IP3 2021-AI for Selecting Audio Codec (LOT 12727)

This lot is generally related to a technique of audio compression in a material exchange format (MXF) file to maintain audio quality. Disclosed is a technique to select an optimal audio codec by creating multiple processed audio clips by compressing and decompressing an original audio clip with different audio codec algorithms. The system creates a matched filter using the original audio clip to determine a power spectrum of each of the processed audio to identify a selected audio codec algorithm for compression. The technology may be implemented in audio processing software, audio and video packaging systems, media players, etc.
