Nick.C: Is an option to specify output file name in the plans for the future, or do you want to stay with just the output directory option?
Yes, I understand the need for the FACT chunk (see this post of yours) but I'm thinking there could be a way of noting in some tag that the file was processed by LossyWAV.The FACT chunk should still be added to the lossyWAV-processed WAV file.But upon losslessly compressing the lossyWAV, perhaps add a tag to the output file that contains the same information as the FACT chunk would. Of course, there is nothing to stop the user from removing this tag later, but that's his fault, so to speak. Of course, it could be more trouble than it's worth, and ultimately you never know how "lossless original" a PCM file is, but if the technical capability exists, we might decide to let the user know in good faith that his file is no longer "pristinely original".
Is it possible yet to use lossywav with multichannel lossless Dolby True HD & DTS Master ?I haven't tried personnaly but I am more & more interested in it ... I am specially scarred by this:1.2.0: Checking of S (=L-R) channel for matrix surround contentshould i wait for 1.2.0 to give it a try ?
lossyWAV 1.1.2 attached to post #1 in this thread.

I haven't been able to download either.

Some questions:Do we need dither?Do we need 32-bit integer processing?Do we need the capability to create correction files?I ask as these all add to the time taken to process files (even if the options themselves are not selected).
... About quality ,I did a few blind tests here ,& could tell the difference, ( with 90% success), ...
lossyWAV does indeed pipe output so there is no need for an intermediate WAV file when encoding to a lossless codec which accepts piped input.--insane (I assume) is the upper quality limit (-q 10). Please supply ABX logs. And samples which you were able to ABX.

-I == --insane == -q 10 = the highest available quality setting.If you go to post #1 in this thread you will find the foobar2000 converter settings for lossyWAV processing piped to FLAC, Tak & Wavpack.foobar2000 also has an ABX capability.Others are more knowledgeable regarding acceptable ABX methodology.If you could upload some representative samples (up to 30 seconds each) of the track(s) which you managed to ABX in the Uploads forum it would be greatly appreciated.
... the only switch I used was "-I". ...
Thanks for the informative replies !I will get to it , this should prove to be a more reliable test !
... my 1st test file provided enough input ...
Quote from: B0RK on 29 January, 2009, 07:01:43 PM... my 1st test file provided enough input ...Really, especially as you were using '-I', didn`t you?What come to my mind is that '-I' uses noise shaping to the max, meaning all the added noise is collected in the 13+ kHz range.This is not expected to be a problem, but who knows for sure?Do you mind testing with the additional switch '-s 0' which disables noise shaping, or a low noise shaping setting like '-s 0.3'?As '-S' is wanted to yield transparent results I'd prefer to have this setting tested. shadowking's proposal of using '-P' is of course intersting too. As a positive side effect for you using '-S' and '-P' testing should be easier.Can you tell a bit about what is wrong with the lossyWAV result?
