BWF (Broadcast Wave Format) not supported

I've tried to play some BWF files and winamp doesn't like them - Error "Couldn't find destination format". Renaming then from .WAV to .MP2 works, but this is a kludge.
BWF are .WAV format files but using MP2 compression, as well as including some extra information blocks. They are used in proffesional broadcasting/editing situations such as radio stations. The 2 main problems I see with winamp is a) not supporting all codecs useable inside .WAV files and b) not being able to show the extra information blocks of BWF.
a) is probably because you have your codecs too closely tied to your file formats (doh!) and b) is just, well, ignorance ;-)
Try http://www.ebu.ch/pmc_bwf.html for some bwf information and http://www.sr.se/utveckling/tu/bwf/ for some sample files (both PCM and MP2 internal data format).

I wouldn't consider it ignorant to overlook a nearly completely useless and unpopularly-used format.

By the way, it's not a bug. This thread belongs in the wishlist.

gonna look into it. these wavs are very similar to those common ones causing "couldn't find destination format" error, but they use mp2 instead of mp3. if we put some general hack to fix mp3 ones, we'll fix bwf too. also, they would probably work if you had mp2 ACM driver installed (don't ask me where to get it).

I posted it as a bug because winamp supports mp2 beautifully on it's own but seemingly not inside a .wav even though this is a valid sub-format.
I work at a radio station and we use BWF, but we can't use winamp so we have to use a 'professional' (ie pay-money-for) player that does support BWF.. Perhaps you could at least add some more helpful feedback to the "coudln't find destination format" error. Eg, at least the type of format...

A workaround for now, is to add WAV to the list of extensions in in_mp3.dll

Prefs -> Input -> MPEG Audio Decoder -> config -> General tab

You might also have to temporarily disable the Wave Input plugin?

Close Winamp
Goto the Winamp\Plugins dir -> rename in_wave.dll to in_wave.dll.off

Of course, this will now disable support for normal uncompressed wav's

But I don't suppose you use Winamp for standard WAV's?

Hopefully though, this WILL get fixed in the next release.
in_wav.dll needs to know when to pass MPEG Layered WAV's onto in_mp3.dll

btw, there was a very similar thread to this one a few months ago, but I've searched the entire forums and can't find it anywhere. I just thought I'd mention this so you know you're not alone
I'd love to know where the thread went though. If I find it I'll let you know.

For more information regarding MMSYSTEM032 - Couldn't find destination format

Check the relevant section from TSGH -> Useful Links

There's also a link to a supposed guaranteed fix, though I'm not sure if it'll work for MP2 Layered WAV's or not. Maybe give it a try.

i think there will be a workaround for that in WA3, but i'm not sure. i don't think it will ever work under WA2.
