Audacity Forum

I have the same problem with 1.3.5. All files exported to MP3 can be played with iTune and iPod, but not with WMP. After I downgraded to 1.3.4, it worked. After some comparison, my wild guess was the MP3 meta data in which IDv3 v2.3 data was encoded in UTF-16 there, may be the reason that confused WMP. 1.3.4 genereates IDv3 v1.0 data, I think.

FYI.

WMP dies on mp3 with only IDv3 v2.3 metadata, which is what 1.3.5 output. It does play file with both v1.0 & v2.3 metadata.

There's a little box in the lower left corner of the main Audacity window.

WMP was expecting Little Endian style tags and our tag library was writing Big Endian. It's fixed in our source code:

or the fix will be in 1.3.8 Beta when released.

I just tried it here. I record with Audacity (1.3.6), do all my track editing in there, then export the tracks as 24 bit WAV files, import them into Cubase SE for mixing, then I use Audacity to make the MP3 and 16 WAV for my demo CD's. The final tracks play fine in WMP. The raw exported WAV files (24 bit) do not. I got the following message

The audio codec identified by the format tag 1 is required to play this file.
To determine if this codec is available to download from the Web, click Web Help.

Web help does nothing, leads to another page and that says it doesn't exist.

I just tried a 16 bit file exported from one of my projects and that opens and plays in WMP okay

FWIW

BTW, the mp3 file is 16 bit, not 32 bit - it may have been made from a 32 bit file, but when converted to mp3 it is changed to 16 bit.

As far as I understand it, MP3s do not store bit depths at all but simply describe how to reconstruct a continuous audio signal in such a way that it resembles the original signal. When a decoder reconstructs this signal, it must quantize it, but the decoder is free to choose any sample size. Almost all decoders use 16 bit, but there are a few 24-bit ones like the MAD plug-in for Winamp.

WMP 10 on Windows XP seems able to cope with 24- and 32-bit signed PCM WAV, and 32-bit float WAV, as exported by Audacity 1.3.8 alpha...

I'm still on 9 here (I use WinAmp for my audio stuff and everything works fine with that). I'll have to get WMP 10 and try it
