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. A single WebRTC media session supports up to 250 participants, however you can reach more participants with media replication. A WebRTC media session can be replicated to up to 40 additional WebRTC media sessions, providing media distribution to a further 10,000 participants. Messaging, media pipelines, speech enhancement, and PSTN audio capabilities are also available with pay-for-use pricing.

    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.

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. The application hosts 20 weekly sessions for students. 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

Total Cost per Week
$3.06 per course session × 20 course sessions per week = $61.20 per week

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. The application hosts 5 keynote presentations each week. 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

Total Cost per Week
$52.224 per session × 5 sessions per week = $261.12 per week 

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.

 

Rate per WebRTC media session attendee minute Rate per PSTN audio minute
Noise reduction with Amazon Voice Focus Included in the per WebRTC media session attendee minute rate $0.0045
Echo reduction with double talk improvement $0.0023 N/A

PSTN Audio Application Usage
$0.002

Each “attendee” (i.e. an instance of your application that has implemented the SDK) 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) it is connected to a meeting session with PSTN audio. 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 per-month basis for DID/DDI and toll-free numbers and by the minute for PSTN access, and for AWS Lambda usage (See AWS Lambda Pricing).

  • 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.
    Service Rate per minute
    Amazon Chime SDK PSTN Audio call recording  $0.0028

    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**)

SIP Trunking

Amazon Chime Voice Connector enables you to connect your on-premises phone systems to the Public Switched Telephone Network (PSTN) and Amazon Chime SDK meetings service, replacing your legacy network. Voice Connector is available for inbound calling only, outbound calling only, or both inbound and outbound calling. Calls to other Voice Connector customers are free of charge. Audio from Voice Connector calls and on-premises SIP-based media recording (SIPREC) devices can be streamed to Amazon Kinesis Video Streams for analytics and machine learning.

Amazon Chime Voice Connector offers pay-per-use pricing with no upfront fees. You can send as little or all of your voice traffic to the Voice Connector paying by the minute for incoming and outgoing calls. The service elastically scales to meet your voice capacity demands. For telephony, Amazon Chime Voice Connector offers both direct inward dial (DID/DDI) and toll-free phone numbers. DID/DDI and toll-free phone numbers are charged at a per number per month rate. There is a charge of 1/10 of the per-minute rate every 6 seconds (minimum of 6 seconds) for any calls based on the type of phone number for inbound calls, and the destination for outbound calls. For Amazon Chime Voice Connector streaming usage, you will be charged 1/10 of the per-minute rate every 6 seconds (minimum of 6 seconds). Charges begin when the called party answers and stops when either party hangs up.

Pricing Examples

Amazon Chime Voice Connector

Consider a company of 50 employees wanting an easy way to chat, and to make outbound phone calls to the public telephone network. The company averages 11,100 monthly minutes of US outbound calls that are connected to the public switch telephone network with Amazon Chime Voice Connector.

The cost for Amazon Chime Voice Connector is:

Outbound Minute Usage Cost = 11,100 (minutes) x $0.0048 (per minute) = $53.28

Total monthly cost: $53.28**

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

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. *

 

Rates

Send message (Standard message up to 4KB)

$0.0007/message

Send control message (Limited to 30 bytes)

$0.000003/message

System message

$0.000003/message

Message delivery

$0.00001/endpoint

Storage

$5/GB-month

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

Media Pipelines

Media capture pipelines allow you to capture the contents of a meeting created using the Amazon Chime SDK and save them to an Amazon Simple Storage Service (S3) bucket of your choice. The S3 bucket must be in the same region as the meeting that is to be captured. The media capture pipeline feature captures meeting audio, video, and content share streams at a per minute per stream rate* and uploads the contents to the designated S3 bucket. Events and data messages are also uploaded, but there is not a separate charge for capturing these items.**

  Rate per minute
Capture of active speaker video and combined audio stream (duration of capture) $0.0034
Capture of combined audio stream (duration of capture) $0.0017
Capture of individual video streams (when active) $0.0017
Capture of individual content share streams (when active) $0.0017

By default, the media capture pipeline with the Amazon Chime SDK provides the ability to capture the mixed meeting audio stream for the duration of the capture with the video of the active speaker when their video is available, along with the content share streams when available. Builders can configure APIs to customize the media capture experience. You can switch the audio stream capture to choose between AudioOnly and AudioWithActiveSpeakerVideo mode, as well as choosing to enable or disable capture of individual video streams and content share streams. You can also use SourceConfiguration to select specific attendee video streams to capture, and do not need to capture all individual streams.

* Cost per minute (including any part minute, measured in 6 second increments at 1/10 the per-minute rate, with a 6 second minimum) to stream media capture pipeline video, audio or content to S3. See Amazon S3 pricing for additional fees related to S3 storage and data transfer. 

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

Media Pipeline 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 sessions need to be captured to play back at a later time for students who missed the lecture. The application hosts 50 weekly sessions that need to be captured for students. Each course includes 1 instructor and 29 students, and is 60 minutes in duration. The application allows the instructor and students to share webcam video and the capture features a video capture of the active speaker and the combined audio from the meeting. The instructor also shares a screen (content) for the duration of the meeting. The CreateMediaCapturePipeline API is called when the class starts and runs the entire duration of the class.

In this example the cost for the Amazon Chime SDK and media capture pipeline is:

Each Course Session

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

Media Capture Pipelines
1 active speaker video and combined audio stream x 60 minutes x $0.0034 per stream-minute = $0.204
1 content stream x 60 minutes x $0.0017 per stream-minute = $0.102

Total for Session
$3.06 for Amazon Chime SDK + $0.204 for active speaker video and combined audio capture + $0.102 for content capture = $3.366

Total Cost per Week
$3.366 per course session with capture × 50 course sessions per week = $168.30 per week

Media Pipeline Pricing Example 2

The developers of a telehealth application have used the Amazon Chime SDK to have audio and video sessions between physicians and patients. All of the sessions need to be captured for compliance reasons. The developers need to capture the audio for the full duration of the meeting as well as the individual video tiles for both the physician and the patient whenever they are active. The application hosts 100 weekly sessions that all need to be captured. On average each session is 20 minutes. The CreateMediaCapturePipeline API is called when the session starts and runs the entire duration of the meeting. 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.

In this example the cost for the Amazon Chime SDK and media capture is pipeline:

Each Session

Amazon Chime SDK
1 patient × 20 minutes + 1 physician × 15 minutes × $0.0017 per attendee-minute = $0.0595 per session

Media Capture Pipelines
1 combined audio stream x 20 minutes x $0.0017 per stream-minute = $0.034 per session
1 patient video stream × 20 minutes + 1 physician video stream × 15 minutes × $0.0017 per stream-minute = $0.0595 per session

Total for Session
$0.0595 for Amazon Chime SDK + $0.034 for combined audio capture + $0.0595 for individual video capture = $0.153

Total Cost per Week
$0.153 per average session with capture × 100 sessions per week = $15.30 per week

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