Abstract:

AES41 provides for the carriage of audio metadata by embedding it in the audio samples themselves. This tightly associates the metadata with the audio, yet makes it fragile so that changes to the audio will invalidate the metadata. Several metadata sets have been defined, covering applications such as cascaded compression (bit rate reduction), and loudness control. This part describes the format for the data to be transmitted with audio decoded from MPEG-1 Layer II or MPEG-2 LSF Layer II encoding. The data may be used to aid a subsequent re-encoding process. A method of carrying this data is described in Part 1 of this Standard.This standard revises AES41-2009: AES standard for digital audio – Recoding data set for audio bit-rate reduction
