transparent audio coding
<audio, compression> A lossy audio compression algorithm is transparent
if the original and decoded signal are indistinguishable to the human ear. The
bit rate depends on the codec and the audio material. Some codecs (e.g. AAC,
MP3) are optimized for transparent coding at a low data rate, others (e.g. VQF,
MP3Pro, AAC+SBR, WMA) for distinguisable but pleasant reproduction at lower bit
rates.
Typical data rates in kbps for different codecs are:
MP1 288-320
MP2 224-256
MP3 160-224
MPEG-2 AAC 128-160
MPEG-4 AAC 112-144
MPEGplus 160-200
