There are other losslessly compressedformats such as = TTA, TAK, WavPack, OptimFrog, etc. However, FLAC is fast, flexible and supp= ort 16 and 24 bits per sample. ALS supports IEEE floating point formats and= multichannel signals.=0AWe have noted that for low-amplitude signals, the = audio can be losslessly compressed with high gain (i.e. the ratio output_si= ze / input_size can be up to 10).Your work sounds quite interesting, good l= uck with it!=0A=0AKind regards,=0A=A0=0A=0AFernando A.
