Fixed the "alternative" timestamp calculation mode. Still this mode is experimental and the default mode seems to work better for me.

Can somebody send me a sample WMA file that is DRM protected or at least run some tests for me with such file?

I added a check for DRM protected files, because such files cannot be processed (for obvious reasons). However I cannot test it without an example file.

Improved "alternative" timestamp calculation mode (option "-x"). Should be a viable alternative now.

can you add multichannel support? also if the source is 24bit then a 24bit pcm wav is better...

from a file like this i get stereo audio (downmixed)...

Hmm, actually my tool should be prepared for multi-channel audio and higher bit-depths. It dumps the audio data as received.

What you see below "[Audio Properties]" is exactly what the WMReader object reports for the audio stream. So it obviously does the down-mix automatically.
I don't know if there is a way to convince the WMReader object to output the "native" audio without downmixing. But I will look into this. Tomorrow...

For the moment, here is a small update that will detect and print out some Codec information.

About multichannel output:

There are other tool (dshow2wav.exe) here : http://forum.doom9.org/showthread.ph...87#post1209087

And the WMA 5.1ch. in WMV only decodes to stereo? thread

Okay, here is a new test version

It gave me some headache, but I think I found a way to read out the "native" sampling rate and channel count of the WMA stream.
Also I will now try to set the output format accordingly. As a result, we can now get multi-channel output as well as 24-Bit.

This version contains a massive clean-up of the recent changes to allow 24-bit and multi-channel output.

Also I added an option to force the "default" output format. Use this, if more than 16-Bit/Stereo output is not desired.

[UPDATE] Added MSVC 9.0 build that should work on Win2k + added Win2k channel workaround [/UPDATE]

Great work, channels are ok, 24 bits resolution is ok, one thing isn't working though: it always downsample to a maximum of 48 kHz from a 96 kHz or 192 kHz file.
Sample: http://samples.mplayerhq.hu/A-codecs...litchannel.wma

BTW the attached file is a VS2008 build which should run on Windows 2000 (not tested on Windows 2000 though but it's working fine on XP).

Last edited by LoRd_MuldeR; 20th July 2011 at 19:28. Reason: Removed attachment, as that version is outdated now (and I included a Win2k build in latest version). Sorry.

Hmm, that one is reported as 48 KHz by the IWMReader/IWMProfile interface, so the output format is set "correctly", I think.

Also MediaInfo reports:
Code:
Audio
ID                               : 1
Format                           : WMA
Format profile                   : Pro
Codec ID                         : 162
Codec ID/Info                    : Windows Media Audio
Description of the codec         : Windows Media Audio 9 Professional - 192 kbps, 48 kHz, 5.1 channel 24 bit 2-pass VBR
Duration                         : 1mn 13s
Bit rate mode                    : Variable
Bit rate                         : 192 Kbps
Channel(s)                       : 6 channels
Sampling rate                    : 48.0 KHz
And Foobar2000 as well as Winamp agree

Also I think more than 48 KHz output is rarely supported by consumer-grade hardware audio interfaces, let alone all the "on board" audio chips...

My mistake, it seems I got confused by the filename from all of these samples I've grabbed, sorry.
And everything is working fine with a 96 kHz file, at least it does with this sample:
http://samples.mplayerhq.hu/A-codecs...56000_1_20.wma

And please, don't forget to approve my VS2008 build from my previous post

Fixed a bug that could cause the tool to crash, when the ASF file had a very long Title or Codec Info.

You live and learn: wcscpy_s() doesn't gracefully truncate the string when the buffer is too small, but invokes Watson crash reporting instead.

"...which causes the application to crash and asks the user if they want to load the crash dump to Microsoft for analysis."

As I said before, Nic had already created a WMA2WAV.EXE ( for adding a .WAV header to WMA files ). Do you still resist renaming your most useful WMA-decompressor ?
