WebRTC Media

The Amazon Chime SDK allows you to add real-time audio, video, screen sharing, and messaging capabilities to your applications. You can simplify operations, and build these features without managing real-time communication infrastructure services. The Amazon Chime SDK elastically scales to your applications needs, and allows your application to place WebRTC media sessions in other AWS regions. Visit the AWS Service Region Table for the list of available regions.

The Amazon Chime SDK offers pay-for-use pricing with no upfront fees. Developers using WebRTC media can choose to implement some or all of the available media modalities (audio, video, and screen share) for a single rate.

Developers can choose between a standard or high definition WebRTC media session. A standard session supports up to 250 interactive participants, with video up to 720p (1280x720) resolution and screen share up to 1080p (1920 x 1080). A high definition session supports up to 25 interactive participants, with video up to 1080p (1920 x 1080) resolution and screen share up to 4K (3840 x 2160).

Both types of sessions can be replicated to up to 40 additional sessions, providing media distribution to 10,000 participants for a standard session and 1,000 participants for a high-definition session.

  • WebRTC Media

  • WebRTC media sessions are billed per minute for each “attendee” (i.e. an instance of your application) while connected to the session, regardless of which media modalities (screen share, screen view, two-way audio, one-way audio, two-way video, or one-way video) are used. 
    Media session capacity minutes are billed based on the capacity set for the meeting and the duration of the meeting. 
    Sessions are billed in 6 second increments, with a 6 second minimum. 

  • Media Replication

  • Media replication is billed minute for each destination WebRTC media sessions, regardless of the number attendees connected to the session. Media replication is billed in addition to the attendee minutes billed for attendees connected to both the destination WebRTC media sessions.

  • Live Connector

  • Live connector enables you to live stream media from Amazon Chime SDK meetings by sending video to streaming platforms such as Amazon Interactive Video Service (IVS), Amazon Elemental MediaLive, Wowza, Facebook Live, and YouTube Live for distribution to a large audience. Customers can live stream real-time media to a large audience by using live connector in conjunction with streaming platforms. Real-time media that can be live streamed include active speaker video along with audio and content share, and composited video. Live connector is billed in addition to the attendee minutes billed for attendees connected to the WebRTC media sessions.

  • Media Capture

  • Media capture allows you to capture the contents of an Amazon Chime SDK WebRTC media session and save them to the Amazon Simple Storage Service (S3) bucket of your choice. Media is stored in 5-second segments that can be used with the concatenation feature to create a single file from a sequence of segments.

    When media is captured, events and data messages are also captured, but there is not a separate charge for capturing these items.

    * Cost per minute (including any part minute, measured in 6 second increments at 1/10 the per-minute rate, with a 6 second minimum. Refer to Amazon S3 pricing for additional fees related to S3 storage and data transfer.

  • Media Streaming

  • Send audio from Amazon Chime SDK WebRTC media sessions to Amazon Kinesis Video Streams. Sending WebRTC session audio to Amazon Kinesis Video Streams provides you with access to the audio for live analysis during the session. You can send the meeting audio to a single stream, the audio for each attendee to a separate stream, or both.

    Media streaming is billed per minute per stream*

    * Cost per minute (including any part minute, measured in 6 second increments at 1/10 the per-minute rate, with a 6 second minimum. Refer to Amazon Kinesis Video Stream pricing for additional related fees.

  • Concatenation

  • Concatenation creates a single file by processing a sequence of segments created by Amazon Chime SDK media capture.  Concatenation supports processing audio, video, content, and transcriptions media segments.  Files created using concatenation can be used for on-demand playback, archived for compliance purposes, or to perform additional analysis using AWS artificial intelligence (AI) services.

WebRTC Media Pricing Example 1

The developers of a learning management system (LMS) have integrated the Amazon Chime SDK into their solution to allow students to attend live lectures from their web application. Each course includes 1 instructor and 29 students, and is 60 minutes in duration. 

In this example the cost for the Amazon Chime SDK is:

Each Course Session

Amazon Chime SDK
30 attendees × 60 minutes × $0.0017 per attendee-minute = $3.06 per course session

Total for Session
30 attendees × 60 minutes × $0.0017 per attendee-minute = $3.06 per course session

WebRTC Media Pricing Example 2

The developers of an online events platform have integrated the Amazon Chime SDK into their solution for keynote presentations. They are using one WebRTC media session for the presenters with media replication to separate WebRTC media sessions for audience members.  Each presentation includes 1 moderator, 1 presenter and 500 audience members, and is 60 minutes in duration.

In this example the cost for the Amazon Chime SDK is:

Each Session

Amazon Chime SDK
502 attendees × 60 minutes × $0.0017 per attendee-minute = $51.204 per presentation session
2 media replications x 60 minutes x $0.0085 per minute = $1.02 per presentation session

Total for Session
$51.204 for attendees + $1.02 for media replication = $52.224 per session

WebRTC Media Pricing Example 3

The developers of virtual fitness application have integrated Amazon Chime SDK into their solution to livestream fitness sessions by sending real-time video to YouTube Live. Each session includes 1 fitness instructor, 5 customers and is of 60 minutes duration.

In this example the cost for the Amazon Chime SDK:

Each Session

Amazon Chime SDK
6 attendees × 60 minutes × $0.0017 per attendee-minute = $0.612 per session

Live connector to send video to third-party streaming platforms*
1 HD video stream x 60 minutes x $0.09 per stream-minute = $5.4 per session

Total for Session
$0.612 for Amazon Chime SDK + $5.4 for sending real-time video to YouTube Live = $6.012

*Streaming platform charges may charge additional fees for distributing content

WebRTC Media Pricing Example 4

A learning management system (LMS) enables students to attend online class from within the web application. Each class includes 1 instructor and 30 students, and is 60 minutes in duration. Classes need to be captured so students can download and replay the class.The application uses Amazon Chime SDK WebRTC media sessions with media capture to create a 1080p composited capture of the meeting audio, the instructor’s webcam video and screen share, and concatenation to create a single file from the capture media segments.  The CreateMediaCapturePipeline API is called when the class starts and runs the entire duration of the class.

In this example the costs for the Amazon Chime SDK are the following:

Each Session (Class)

WebRTC media
1 instructor + 30 students = 31 attendees31 attendees × 60 minutes × $0.0017 per attendee-minute = $3.162 per session

Media capture
1 x 1080p composited media x 60 minutes x $0.0125  per minute = $0.75 per session

Concatenation

1 sequence of composited media segments x 60 minutes x $0.002 per minute = $0.12 per session

Total for Session
$3.162 for WebRTC Media + $0.75 for media capture + $0.12 for concatenation = $4.032 per session

WebRTC Media Pricing Example 5

A telehealth application enables online consultations between physicians and patients. Consultations are typically takes 20 minutes. All of the sessions need to be captured for compliance reasons.

The application uses Amazon Chime SDK WebRTC media sessions with media capture and concatenation to capture of the meeting audio and the individual webcam video of the physician and the patient.  The patient joins 5 minutes before the physician and begins sharing video immediately upon joining the session. The physician shares video the entire 15 minutes while on the session.  The CreateMediaCapturePipeline API is called when the consultation starts and runs the entire duration of the consultation. 

In this example the costs for the Amazon Chime are the following:

Each Session (consultation)

WebRTC media
1 patient × 20 minutes × $0.0017 per attendee-minute = $0.034 per session

1 physician × 15 minutes × $0.0017 per attendee-minute = $0.0255 per session

= $0.0595 per session 

Media capture

1 combined audio stream x 20 minutes x $0.0017 per stream-minute = $0.034 per session

1 patient video stream × 20 minutes × $0.0017 per attendee-minute = $0.034 per session

1 physician video stream × 15 minutes × $0.0017 per stream-minute = $0.0255 per session

= $0.0935 

Concatenation

1 sequence of audio segments x 20 minutes x $0.002 per minute = $0.04 per session

1 sequence of patient video segments x 20 minutes x $0.002 per minute = $0.04 per session

1 sequence of physician video segments x 15 minutes x $0.002 per minute = $0.03 per session

= $0.11 per session 

Total for Session

$0.0595 for WebRTC media + $0.0935 for media capture + $0.11 for concatenation = $1.1045 per session 

* May incur additional charges for using other services or products.

WebRTC Media Pricing Example 6

A language school provides online tutoring to help student learn new languages.  Tutoring sessions are one-on-one and typically last 30 minutes.  During each session, the student performs a 5-minute assessment where their speech is analyzed by a proprietary algorithm.

The application uses Amazon Chime SDK WebRTC media sessions with audio streaming to Kinesis Video Streams to perform the assessment.

In this example the costs for the Amazon Chime SDK are the following:

Each Session

WebRTC media
2 attendees × 30 minutes × $0.0017 per attendee-minute = $0.102 per session

Audio streaming
1 x attendee x 5 minutes x $0.0017 per attendee-minute = $0.0085 per session

Total for Session
$0.102 for WebRTC media + $0.0085 for streaming to KVS = $0.1105 per session 

Speech Enhancement

Amazon Chime SDK offers machine-learning (ML) based speech enhancement capabilities including noise reduction using Amazon Voice Focus and echo reduction. Noise reduction uses ML to help reduce environmental noises like wind, fans, and running water, background noises like lawn mowers and dogs barking, and foreground noises like keyboard typing and shuffling papers.

Echo reduction is designed to reduce disruptive acoustic echoes that can happen in a virtual meeting when the sound played by a participant’s loudspeaker is picked up by their own microphone and recirculated back into the meeting. Standard WebRTC echo cancellation mechanisms are available as a default in the Amazon Chime SDK, but customers can opt to upgrade to Amazon Chime SDK’s state-of-the-art ML-based echo reduction for improved voice quality, especially during double-talk situations when multiple virtual meeting participants are speaking at the same time. By providing improved echo control, Amazon Chime SDK’s echo reduction helps reduce the risk of echo being introduced to a meeting by users who prefer to engage without a headset or headphones.

Call analytics

  • Call analytics
  • Call recording

Call Analytics Pricing Example 1

Consider a bank that wants to use Amazon Chime SDK call analytics to generate real-time transcriptions from communication between financial traders and to obtain voice-based insights using the speaker search capability. On average, each communication lasts 30 minutes and there are 1,000 calls per month between the traders.

In this example the cost for Amazon Chime SDK call analytics is as follows*:

Cost per call:
30*$0.023 = $0.69

Total cost per month:
1,000*$0.69 = $690

*Additional fees apply for Amazon Transcribe, Amazon Kinesis Video Streams, and Amazon S3

Call Analytics Pricing Example 2

Consider an insurance company that wants to use Amazon Chime SDK call recording to record conversations between its insurance agents and customers for compliance and training purposes. On average, each call lasts 15 minutes and there are 15,000 calls per month.

In this example the cost for the Amazon Chime SDK call recording is as follows*:

Cost per call:
15*$0.010 = $0.15

Total cost per month:
15,000*$0.15 = $2,250

*Additional fees apply for Amazon Kinesis Video Streams, and Amazon S3
 

Public Switched Telephone Network (PSTN) Audio

The Amazon Chime SDK allows you to add phone numbers for your meetings so that attendees can participate using a landline or mobile phone. For dial in phone numbers, choose the Phone Numbers link below, and using the AWS Region drop-down selector, select an AWS Region to see the country phone numbers available from that AWS Region. For dial out, the service supports calling to over 100 countries. To use PSTN audio, builders create a serverless IVR application using AWS Lambda.

A “session” is either a new incoming call or outgoing call. PSTN Audio Application Usage is billed for each minute, including any part minute, measured in 6 second increments at 1/10 the per-minute rate, with a 6 second minimum. Calls are automatically connected to an Amazon Chime SDK meeting session. In addition to the PSTN Audio Application Usage, customers will be billed by the minute for connecting to an Amazon Chime SDK meeting session. Customers will also be billed on a per-month basis for DID/DDI and toll-free numbers, by the minute for PSTN access, and for AWS Lambda usage (See AWS Lambda Pricing). An example is given below.

  • Outbound Calling
  • Call Recording
  • With Amazon Chime SDK PSTN Audio call recording, you are only charged for what you use, on a per-minute rate for the time that call recording is on.

    Pricing example

    Let’s assume that you want to record without transcription 200,000 calls per month on the consumer leg, and the average call is about 10 minutes each. This equals 2 million minutes of audio per month in the US East (N. Virginia) region. In US East (N. Virginia), with pricing $0.0028/minute your monthly charges will be as follows.

    Calculation of Amazon Chime SDK PSTN Audio call recording monthly charge:

    Monthly call minutes recorded in US East (N. Virginia) = 2 million minutes

    Total cost = T minutes * P price/min

    Total cost for Amazon Chime SDK PSTN Audio call recording = 2,000,000 * $0.0028 = $5,600

PSTN Audio Pricing Example

Dialing into an Amazon Chime SDK Meeting

Consider a company of 50 employees who wants to make it easy to join Amazon Chime SDK meetings from a landline or mobile phone. The company wants to publish a US toll-free phone number so employees don't incur the costs calling into meetings. On average each employee places 10 calls per month that are 22 minutes in length for a total of 11,000 monthly minutes.

The costs for Inbound Calling, PSTN Audio Application Usage, AWS Lambda invocations, Connecting to an Amazon Chime SDK meeting session, and the toll-free phone number rental are:

Inbound Calling (Toll-free) Minute Usage Cost
11,000 (minutes) x $0.011910 (per minute) = $131.01

PSTN Audio Application Usage Cost
11,000 (minutes) x $0.002 (per minute) = $22.00

AWS Lambda Requests Cost
$0.2 (per 1M requests) / 1,000,000 x 5 (average invocations per call) x 500 (calls per month) = $0.0005

AWS Lambda Duration Cost
$0.0000000021 (cost for every 128MB-millisecond) x 5 (average invocations per call) x 5 (duration of each request in milliseconds) x 500 (calls per month) = $0.00105

Connection to Amazon Chime SDK meeting session
11,000 (minutes) x $ $0.0017 (per minute) = $18.70

Toll-free Phone Number Cost
$1*

Total monthly Cost
$131.01 + $22.00 + $0.0005+ $0.00105+ $18.70 + $1 = $172.71155**

Adding the noise suppression option for the PSTN calls using Amazon Voice Focus.
As a builder, you can choose if and how your service leverages noise suppression for the PSTN calls. You can programmatically (a) implement a centralized control to enable/disable voice focus for all calls or (b) allow end-users to enable/disable Voice Focus on the client side, as they choose, for all calls, some calls, or parts of the calls, analogous to mute/unmute operation; you may also choose combine these options.

Example (a): Amazon Voice Focus permanently enabled for all calls. 
Amazon Voice Focus cost $0.0045 (per user per minute) x 11,000 (minutes) = $49.50
Total monthly Cost (with noise suppression enabled for all PSTN calls) $172.71155 + $49.50 = $222.21155 (rounded to $222.21**)

Example (b): Amazon Voice Focus is configurable and used for 40% of the PSTN call time.
Amazon Voice Focus cost $0.0045 (per user per minute) x 11,000 (minutes) x 40% = $19.80
Total monthly Cost (with noise suppression enabled for 40% of the PSTN call time) $172.71155 + $19.80 = $192.51155 (rounded to $192.51**)

Messaging

Messaging is pay-per-use with rates for sending messages, message delivery, and message storage. The Amazon Chime SDK only charges you for what you use, allowing you to scale as needed. *

The Amazon Chime SDK can be integrated with other AWS Services, including Amazon S3 for message attachments. Amazon Chime SDK charges do not include usage for other AWS services.**

Message delivery is charged per endpoint. Ten participants, each connected from a single device through an active websocket, would result in ten separate delivery charges. Separate message delivery charges also apply each time the ListChannelMessage API is called to retrieve message history and when messages are sent to Amazon Pinpoint as a push notification.

System messages are messages Amazon Chime SDK sends for events like participants joining or leaving a channel. For a complete list of system messages, refer to the Developer Guide.

The volume of storage billed in a month is based on the average storage used throughout the month. We measure your storage usage in "TimedStorage-ByteHrs," which are added up at the end of the month to generate your monthly charges. Storage size is measured based on the number of objects stored. Each standard channel message is counted as 4KB. Each control message is 30 bytes. All other objects, including channels, app instances, app instance users, admins, channel moderator, channel memberships, user bans, and read timestamps, are 1KB each.

* Except as otherwise noted, our prices are exclusive of applicable taxes and duties.

Messaging Pricing Example 1

The developers of a learning management system (LMS) have integrated the Amazon Chime SDK into the solution to allow students to attend live lectures from their web application. The application hosts 100 weekly sessions for its students. Each session has a chat channel available for students and teachers to communicate. Each session includes 1 instructor and 29 students. For each session, there are an average of 50 standard messages sent and 35 control messages for features built into the chat experience. Control messages in this example do not persist. Messages are stored for 15 days and then are deleted via a retention policy.

(Please note: In this example, we assume the channel and all users were already created before the session so they are not included in storage cost for the session, but would be included in the customers overall storage cost. All participants are connected via one client for the same period of time so receive the same number of messages. This example also assumes 730 hours in a month, (365 days in a year x 24 hours in a day / 12 months in year).)

In this example, the cost for messaging is:

Each Course Session

Messages
31 system messages (30 add channel members + 1 delete channel) x $0.000003 = $0.000093
50 messages sent × $0.0007 per message = $0.035
35 control messages sent x $0.000003 = $0.000105
116 messages delivered x 30 participants x $0.00001 = $0.0348

Storage
50 standard messages x (4 x 1024) x 15 days x (24 hours / day) = 73,728,000 Bytes-Hours = 0.0687 GB-Hours
In GB-Month = 0. 0687 GB-Hours/ (730 hours/month) = 0.000094 GB-Month
Total storage cost = 0.000094 x $5/GB-Month = $0.000470

Total for session
$0.000093 for system messages + $0.035 for standard messages + $0.000105 for control messages + $0.0348 for message delivery + $0.000470 for storage = $0.0705 per session

Total Cost per Week
$0.0705 per session × 100 sessions per week = $7.05 per week

Messaging Pricing Example 2

A large brand hosts a product showcase to announce a new product, broadcast to 1,000 viewers. Viewers are all included in a chat channel where they can communicate with each other and the host via chat messaging. During the broadcast, 1,000 standard messages are sent. Messages are stored for 30 days and then deleted via a retention policy.

(Please note: In this example, we assume the channel and all users were already created before the session so they are not included in storage cost for the session, but would be included in the customers overall storage cost. All participants are connected via one client for the same period of time so receive the same number of messages. This example also assumes 730 hours in a month, (365 days in a year x 24 hours in a day / 12 months in year).)

In this example, the cost for messaging is:

1,001 system messages sent (1,000 add members + 1 delete channel) x $0.000003 = $0.003
1,000 messages sent x $0.0007 per message = $0.70
2,001 messages delivered x 1,000 participants x $0.00001 per delivery = $20.01
1,000 standard messages x (4 x 1024) x 30 days x (24 hours / day) = 2,949,120,000 Bytes-Hours = 2.75 GB-Hours
In GB-Month = 2.75 / 730 hours/month = 0.003767 GB-Month
Total storage cost = 0.003767 GB-Month x $5/GB-Month = $0.01884

Total Cost for the session
$0.70 for messages + $20.01 for deliveries + $0.01884 for storage = $20.73

Messaging Pricing Example 3

A delivery company uses Amazon Chime SDK messaging to connect delivery drivers to customers. Both the delivery driver and the customer use the delivery company’s mobile app. Channels are created for every delivery. For deliveries where the delivery driver and customer contact each other, there are an average of 5 messages sent, and users typically close the app after sending a message, so push notifications are sent for all messages. After push notifications are delivered to users, users click on the notification and load the chat which uses the ListChannelMessages API to load the messages. System messages are sent when users are added to the channel, and when the channel is deleted. In most cases the users are not connected to the WebSocket when this happens so there are no delivery charges for the 3 system messages sent. Messages are stored for 30 days based on the retention policy set by the delivery company. Below is an example of how to calculate the cost for a single delivery where the driver and the customer exchange 5 messages.

(Please note: push notifications in the Amazon Chime SDK are sent through an integration with Amazon Pinpoint. Amazon Pinpoint charges are not included in the example below. See Amazon Pinpoint’s pricing page for detail on pricing for push notifications. In this example, because the user closes the application and reopens the channel for each new message there are 5 different calls for ListChannelMessages. If the channel were opened and ListChannelMessages called only after all messages were sent, there would be only one charge. ListChannelMessages can return up to 50 messages per call.) In this example, the Amazon Chime SDK messaging cost for single delivery with 5 messages sent between the delivery driver and customer:

  • 5 standard messages sent x $0.0007 per message = $0.0035
  • 3 system messages x 0.000003 per system message = $0.000009
  • $0.00001 x 5 for delivery to Amazon Pinpoint for push = $0.00005
  • $0.00001 x 5 ListChannelMessages API calls, one for each time the user opens the channel to read new messages = $0.00005
  • 5 standard messages x (4 x 1024) x 30 days x (24 hours / day) = 14,745,600 Bytes-Hours = 0.01373 GB-Hours
  • In GB-Month = 0.01373 / 730 hours/month = 0.0000188122 GB-Month
    Total storage cost = 0.0000188122 GB-Month x $5/GB-Month = $0.00009406

Total cost for Amazon Chime SDK for a single delivery: $0.0035 for messages + $0.000009 for system messages + $0.0001 for deliveries + $0.00009406 for storage = $0.00370306
