MPAI thanks Marina Bosi, Mert Burkay Çöteli, Gérard Chollet, Hüseyin Hacıhabiboğlu, and Mark Seligman who participated in the development of CAE-USC V2.2

MPAI-CAE V2.1

MPAI has developed Technical Specification – Context-based Audio Enhancement (MPAI-CAE) V2.1 implementing all the changes required by the new web-based format of MPAI Technical Specifications.

MPAI thanks Marina Bosi, Mert Burkay Çöteli, Gérard Chollet, Hüseyin Hacıhabiboğlu, and Mark Seligman who participated in the development of CAE-USC V2.1.

MPAI-CAE V2.0

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 Acknowledges the important contributions made by Marina Bosi, Mert Burkay Çöteli, Nadir della Pozza, Mark Seligman, and Matteo Spanio  in the development of MPAI-CAE V2.0.


MPAI-CAE V1.4

Read Conformance Testing Specification: Context-based Audio Enhancement (MPAI-CAE) V1.4.
