nRF Audio application feature support Application
Description
Limitations
Maturity level
Broadcasting audio using Broadcast Isochronous Stream (BIS) and Broadcast Isochronous Group (BIG).
Play and pause emulated by disabling and enabling stream, respectively.
The following limitations apply:
One BIG with two BIS streams.
Audio input: USB or I2S (Line in or using Pulse Density Modulation).
Configuration: 16 bit, several bit rates ranging from 32 kbps to 124 kbps.
Experimental
Receiving broadcast audio using BIS and BIG.
Synchronizes and unsynchronizes with the stream.
The following limitations apply:
One BIG, one of the two BIS streams or a mixed stereo comprising of the two (selectable).
Audio output: I2S/Analog headset output.
Configuration: 16 bit, several bit rates ranging from 32 kbps to 124 kbps.
Experimental
One Connected Isochronous Group (CIG) with two Connected Isochronous Streams (CIS).
Transmitting unidirectional or transceiving bidirectional audio using CIG and CIS.
The following limitations apply:
Audio input: USB or I2S (Line in or using Pulse Density Modulation).
Audio output: USB or I2S/Analog headset output.
Configuration: 16 bit, several bit rates ranging from 32 kbps to 124 kbps.
Experimental
Receiving unidirectional or transceiving bidirectional audio using CIG and CIS.
Coordinated Set Identification Service (CSIS) is implemented on the server side.
The following limitations apply:
One CIG, one of the two CIS streams or a mixed stereo comprising of the two (selectable).
Audio output: I2S/Analog headset output.
Audio input: PDM microphone over I2S.
Configuration: 16 bit, several bit rates ranging from 32 kbps to 124 kbps.
Experimental
nRF Audio DNs and QDIDs
See the following pages for the Design Numbers (DNs) and Qualified Design IDs (QDIDs) for SoCs that are compatible with nRF Audio applications:
A full Audio product DN will typically require DNs and QDIDs for the Controller component, Host component, Profiles, and Services component and LC3 codec component. The exact DN/QDID numbers depend on the project configuration and the features used in the application.
Note
The DNs/QDIDs listed in the Compatibility Matrix might not cover all use cases or combinations. The full details of what is supported by a given DN or QDID can be found in the associated Implementation Conformance Statement (ICS).
The Audio applications do not demonstrate the full capabilities of the underlying DNs and QDIDs. At the same time, the Audio applications may demonstrate features not available in the underlying DNs or QDID.
