A lossy MPEG audio format used in broadcast and legacy media workflows. MP2 is Layer II audio and is distinct from the later MP3 Layer III format.
Bitrate and sample-rate choices must be supported by the encoder; output does not become lossless.
MP2 file format guideA simple audio container associated with Sun and Unix systems. An AU header describes the sound encoding, sample rate, and channel count.
Tested output uses signed 16-bit big-endian PCM; AU also has encodings with different playback requirements.
AU file format guideChoose the sample rate, trim range, and mono or stereo output. Compressed audio formats can discard detail; converting to a lossless format cannot restore sound already lost. Container support depends on the codec inside the file.
