Specification Details

Common Audio Profile 1.0

Common Audio Profile (CAP) specifies procedures to start, update, and stop unicast and broadcast Audio Streams on individual or groups of devices using procedures in the Basic Audio Profile (BAP). This profile specifies procedures to control volume and device input on groups of devices using procedures in the Volume Control Profile (VCP) and the Microphone Control Profile (MICP). This profile specification also refers to the Common Audio Service (CAS).

The following Errata Corrections are mandatory when claiming compliance to Common Audio Profile:

  • Errata Correction 18665 changes the compatible Core Specification version from Version 5.3 to Version 5.2, because the features introduced in Version 5.3 are not required for the implementation of CAP.
  • Errata Correction 18898 clarifies the requirements for the use of Cross-Transport Key Derivation (CTKD) to generate Long Term Keys (LTKs) for devices operating over both the Low Energy (LE) and Basic Rate/Enhanced Data Rate (BR/EDR) transports, harmonizing the requirements with updated Basic Audio Profile (BAP) requirements.
