lossyWAV 1.2.0 is released.
lossyWAV is a near lossless audio processor which dynamically reduces the bitdepth of the signal on a block-by-block basis. Bitdepth reduction adds white noise to the processed output. Changes from 1.1.0c:

I have some trouble with mp3 transcoding. Last month i compared original V5 mp3 vs lossywav -P V5 mp3 . I abxed 5/5 several times on nearly every sample i tried. The problem wasn't always noticeable but sound very peculiar - like an artifact. Today i tried again with v1.2 -q 2.5, 3.0 and 1.5. I found a passage again and abxed 5/5, the narrowed it down and got 8/8
At -q 4 i didn't abx it. Not sure what is happening or what quality level is needed. With wv lossy 300k range its generaly much harder. I remember Bryant mentioning lossywav noise goes in steps of 6db - could that be problem for transcoding ? |

QUOTE (shadowking @ Dec 21 2009, 12:56)  At -q 4 i didn't abx it. Not sure what is happening or what quality level is needed. maybe you have established that lossyWav -q 4 is needed for your transcodings. Keep in mind that lossyWav was never specifically tuned for transcoding. It is just hoped that it has an advantage to other lossy->lossy transcoding. All depends on how the last encoder handles the added noise... With lossyWav, due to the tuning that has been done, every release you must again find your "sweetspot" -q value. And now there is also the alternative setting with --altpreset, that has a subtle different range. I'm not complaining, it's progress  .
