lossyWAV 1.2.0 released, Added noise WAV bitdepth reduction method Options

[2E7AH]

thanks for your help and program now it works great (with your modified batch script)
I was using CueTools lossyFLAC feature for correction files, but now it's much easier for me

Maybe all this parameters thing can be simplified?

@Steve Forte Rio
Thanks for the configuration and the batch file.
I'm trying to figure out how the batch file has to look, if I'll want to join the created files? (correction file+ loosy.flac file)

Any help would be appreciated.

[Steve Forte Rio]

Thanks for the configuration and the batch file.

Thanks to 2E7AH and Nick.C

[2E7AH]

seems I posted wrong code
looking to it now, I'll post corrected later

[2E7AH]

OK, nevermind the script, I'll post later as batch or if I can't as vbs, but the point was that merging input and correction files doesn't produce bit identical audio file
Why is that?

[2E7AH]

if someone can delete above two post please do

Here is the script:

lossyFLACcorr.bat

CODE

if not exist "%~n2.lwcdf.flac" goto bye
c:\"Program Files"\encoders\flac.exe -d -s "%~n2.lwcdf.flac"
c:\"Program Files"\encoders\lossywav.exe "%1" & "%~n2.lwcdf.wav" -M -Q --below --silent && del "%~n2.lwcdf.wav"
c:\"Program Files"\encoders\flac.exe -s "%~n1.lossy.wav" -o "%~n2.fla" && del "%~n1.lossy.wav"
:bye

extension: fla
parameters: /d /c c:\"Program Files"\encoders\lossyFLACcorr.bat %s %d

problem with piping double extension destination file avoided with using .fla extension for merged file
the script is just illustrative, it's not for usage - why lossyWAV.exe passes merged file to command line (so launches associated program) I don't know, as I don't know how to interpred below results, but I hope it's just mis-usage from my side:

[Nick.C]

Using the command line:

CODE

lossywav ..\samples\eig.wav -C

produces two files: eig.lossy.wav and eig.lwcdf.wav in the current directory.

Using the command line:

CODE

lossywav eig.lossy.wav --merge

produces one file (if eig.lwcdf.wav is present in the same directory as eig.lossy.wav), i.e. eig.wav.

Using the command line:

CODE

comp ..\samples\eig.wav eig.wav

should result in "Files compare OK".

[2E7AH]

So, what to do with FLAC?

If lossy.flac and lwcdf.flac are converted to corresponding wavs then run:

CODE

lossyWAV.exe lossy.wav -M

equals:
FACT Data missing (lossy.wav)

I even downloaded source files to look for the error:

CODE

if (btrdchunk.fact.header.size=0) then lossyWAVerror('FACT Data missing (lossy.wav).',$12);

Is there obligation for some wav header?

runing:

CODE

lossyWAV.exe lossy.wav & lwcdf.wav -M

produces desired file which isn't bit identical with the original file

[Nick.C]

So, what to do with FLAC?

If you create the lossyFLAC file using piped output to FLAC then the FACT chunk goes missing because FLAC will not store it.

When creating FLAC from WAV, please remember to add "--keep-foreign-metadata" to the FLAC command line to preserve the FACT chunk. eg.:

CODE

@echo off
flac -d sample.lwcdf.flac --keep-foreign-metadata
flac -d sample.lossy.flac --keep-foreign-metadata
lossywav sample.lossy.wav -M --stdout|flac - -5 -osample.flac
del sample.lossy.wav
del sample.lwcdf.wav

[2E7AH]

well, I used your batch script which includes that switch:

CODE

c:\programme\flac\lossyWAV.exe %1 %3 %4 %5 %6 %7 %8 %9 --below --silent
if exist "%~N1.lwcdf.wav" c:\programme\flac\flac.exe -b 512 -l 6 -e -m -r 2 -f --totally-silent --keep-foreign-metadata "%~N1.lwcdf.wav" -o"%~N2.lwcdf.flac"&&del %~N1.lwcdf.wav
c:\programme\flac\flac.exe -b 512 -l 6 -e -m -r 2 -f --totally-silent  --keep-foreign-metadata "%~N1.lossy.wav" -o"%~N2.flac"
del "%~N1.lossy.wav"

It's working finally, thanks, but all this is too far from common user

[Agent69]

I finally got around to trying LossyWAV this weekend as my lossless FLAC music library is too big for my netbook's hard drive. I have to say that I am really impressed. I used the parameters in Nick's signature and I have not noticed a difference between the original lossless versions and the lossy ones (although I do have tin ears).

By the way, adding the libfftw3-3.dll library file to my LossyWAV directory produced an incredible speed up in LossyWAV processing. I would highly recommend it to anyone processing a lot of files.

[2E7AH]

I got PMed about batch scripts, so I'm posting it here + to make life easier for others who want to try this and use foobar:

lossyFLAC.bat

CODE

goto %1
goto end
:correction
c:\"Program Files"\encoders\lossywav %2 %4 %5 %6 %7 %8 %9 --%1 --below --silent
c:\"Program Files"\encoders\flac -b 512 -l 6 -e -m -r 2 -f --totally-silent --keep-foreign-metadata "%~n2.lwcdf.wav" -o"%~n3.lwcdf.flac"
c:\"Program Files"\encoders\flac -b 512 -l 6 -e -m -r 2 -f --totally-silent --keep-foreign-metadata "%~n2.lossy.wav" -o"%~n3.flac" && del %~n2.lwcdf.wav %~n2.lossy.wav
goto end
:merge
if not exist "%~n3.lwcdf.flac" goto end
c:\"Program Files"\encoders\flac -s -d "%~n3.flac" "%~n3.lwcdf.flac" --keep-foreign-metadata && ren "%~n3.wav" "%~n3.lossy.wav"
c:\"Program Files"\encoders\lossywav "%~n3.lossy.wav" -M --below --silent && del "%~n3.lossy.wav" "%~n3.lwcdf.wav"
c:\"Program Files"\encoders\flac -s --ignore-chunk-sizes -5 "%~n3.wav" -o"%~n3.fla"
:end

correction part produces %filename%.lossy.flac and %filename%.lossy.lwcdf.flac:


merge part produces %filename%.lossy.fla file which is identical to original file:

All tracks decoded fine, no differences found.

notes:
- because flacs aren't decoded with foobar (nevertheless temp wav is created then delated) but with flac.exe, don't forget that destination has to end in %filename% or equivalent when using merge (output file name format in converter dialog)
- if this is done in foobar media library it's good to exclude *.lwcdf.flac file types from library
- flac parameters for merged files are default foobar parameters for flac encoder, so they can be changed as desired correcting the last significant line in script
- if it's not too obvious, first parameter passed to batch file tell the script what to do (correction, merge or nothing)

have fun

[lvqcl]

By the way, adding the libfftw3-3.dll library file to my LossyWAV directory produced an incredible speed up in LossyWAV processing.

Really? As far as I know FFTW library works faster with floats (4 bytes, single precision) than doubles. If single precision is enough it should significantly speed up FFT calculation.

[Nick.C]

lossyWAV uses data type double for FFT calculations - this was due to early differences between the Matlab output and the Delphi output which were traced back to the FFT calculations.

.... and from me too. The --correction / --merge parameters were implemented quite some time ago but I have not given much thought to re-integration using foobar2000, for example. Thanks for your efforts and patience in creating / testing the batch file.

[Bollerkopp]

Hi,

I tried your script and the "correction"-part works great. I get the "lossy.flac"- and the "lossy.lwcdf.flac"-files... all fine.

But when I try the "merge"-part I get the conversion-error (e.g.):

An error occured while finalizing the encoding process (Object not found) : "G:\Downloads\Alice In Chains - Black Gives Way To Blue\Alice In Chains - Black Gives Way To Blue - 02 Check My Brain.fla"

This is my adjusted script:

CODE

goto %1
goto end
:correction
d:\Programme\foobar2000\Encoder\lossyWAV\lossyWAV %2 %4 %5 %6 %7 %8 %9 --%1 --below --silent
d:\Programme\foobar2000\Encoder\Flac\flac -b 512 -l 6 -e -m -r 2 -f --totally-silent --keep-foreign-metadata "%~n2.lwcdf.wav" -o"%~n3.lwcdf.flac"
d:\Programme\foobar2000\Encoder\Flac\flac -b 512 -l 6 -e -m -r 2 -f --totally-silent --keep-foreign-metadata "%~n2.lossy.wav" -o"%~n3.flac" && del %~n2.lwcdf.wav %~n2.lossy.wav
goto end
:merge
if not exist "%~n3.lwcdf.flac" goto end
d:\Programme\foobar2000\Encoder\Flac\flac -s -d "%~n3.flac" "%~n3.lwcdf.flac" --keep-foreign-metadata && ren "%~n3.wav" "%~n3.lossy.wav"
d:\Programme\foobar2000\Encoder\lossyWAV\lossyWAV "%~n3.lossy.wav" -M --below --silent && del "%~n3.lossy.wav" "%~n3.lwcdf.wav"
d:\Programme\foobar2000\Encoder\Flac\flac -s --ignore-chunk-sizes -5 "%~n3.wav" -o"%~n3.fla"
:end

And here the encoder settings:

Encoder: C:\WINDOWS\system32\cmd.exe
Extension: fla
Parameters: /d /c d:\Programme\foobar2000\Encoder\lossyFLAC.bat merge %s %d

What could be the problem? And what do you mean exactly with "- ... don't forget that destination has to end in %filename% or equivalent when using merge (output file name format in converter dialog)"? Is here the point?

Thanks in advance.

[2E7AH]

thanks to all for their feedback on the script, I redirect that to the program author and people involved in it

while I doubted if I should post here (as it is Validated News forum) or open new thread, it seems that I should have opened new thread

@Bollerkopp: I guess you run merge on original file (%filename%.flac) and not the lossy one (%filename%.lossy.flac)

line: if not exist "%~n3.lwcdf.flac" goto end checks if "%filename%.lwcdf.flac" exists, and if it doesn't it ends the script
%~n3 is the name part of the destination file (%d in converter) that you enter here:


I modified my converter dialog, but you'll get the point

[Bollerkopp]

Thanks for your answer.

But no, I used it on the lossy ones (.lossy.flac).

This is how I have done:

1. Convert an album from my Media Library (Monkey's Audio-files... Path: "F:\Musik\A-C\Alice In Chains - Black Gives Way To Blue") to ".lossy.flac" (and ".lossy.lwcdf.flac") - the correction-part.



2. Then I put all the ".lossy.flac"-files from this folder in a playlist and select the merge-part in the converter.


In the Converter-settings under "Output files" - "Convert each track to an individual file" it looks like this:

CODE

%artist% - %album%\$if2(%artist%,unknown artist) - $if2(%album%,unknown album) $if2('CD'%discnumber%,) - [%tracknumber%] %title%)

This post has been edited by Bollerkopp: Jan 19 2010, 07:35

[2E7AH]

you should run converter only on .lossy.flac files (excluding .lwcdf.flac files), and about output name format I won't repeat myself

[2E7AH]

also I just now noticed that I was merging in the source file folder, so maybe that's the problem, as I don't know of a way how foobar could give source file path to the encoder: %s gives destination path and %d gives destination name, or to put it differently - when using merge do this:

- "source track folder" must be selected for output path
- %filename% must be name format of output file

and somehow I forgot to clean up lossywav wav output so please add && del "%~n3.wav" to the last line:

CODE

c:\"Program Files"\encoders\flac -s --ignore-chunk-sizes -5 "%~n3.wav" -o"%~n3.fla" && del "%~n3.wav"

[Bollerkopp]

Yes, I run it on the ".lossy.flac."-files only. That was not the problem. The problem was the name format of the output file. Now I changed it to "%artist% - %album%\%filename%" and it works. Sorry for overlooking it.

I adjusted the last line... now all is fine. Thank you very much for your script and the effort.

[lvqcl]

lossyWAV uses data type double for FFT calculations - this was due to early differences between the Matlab output and the Delphi output which were traced back to the FFT calculations.

Well, maybe this accuracy is redundant?
