From https://www.armbbs.cn/forum.php?mod=viewthread&tid=108801 , translated ty google:QuoteBLA Basic Lossless Audio
is a lossless audio compression format I modified based on SLAC.
SLAC is a simple lossless audio compression format written by David Bryant, one of the authors of WAVPACK. It can be found here https://github.com/dbry/slac The original intention of the author of the original file is to create a compression format that is comparable to FLAC level 0. After testing and optimization, I made BLA Basic Lossless Audio.
I think , bla, this format is ideal for the card with lite memory et performance (cpu), not for PC ou smartphone
