Context-based Audio Enhancement (MPAI-CAE)

Context-based Audio Enhancement (MPAI-CAE) is an MPAI standard that improves the user experience for several audio-related applications including entertainment, communication, teleconferencing, gaming, post-production, restoration etc. in a variety of contexts such as in the home, in the car, on-the-go, in the studio, etc.

MPAI is making an online presentation of MPAI-CAE V1 and its reference software on 2023/07/07 at 14 UTC. Register here to attend.

MPAI has developed MPAI-CAE V2 containing the data formats required by the Audio Scene Description Composite AIM. This AIM receives an audio stream from a microphone array and produces a description of the orientation of the composing speech streams. MPAI-CAE V2 can be downloaded from
