Hi,
What's the diference between these three Uncompressed Export Formats (Preferences>File Formats):
AIFF (Apple/SGI 32 bit float), Signed 32 bit PCM (Preferences>File Formats>Other)
and 32 bit float (Preferences>File Formats>Other)?
Thanks in advance

If you need to know a good format to export, let us know how you intend to use the exported data. ie. Is it going to be imported into a pc, or a mac, etc.

Hi,
Fisrt of all, thanks a lot for your reply. I'm a Mac user, that's why I've only listed the Mac related export formats.There are more export formats available there, but they are intended for PC users. Any clues?

I'm not much of a mac user (yet), though I have one I haven't done much audio with it.
I would use... format:other, header:(AIFF/SGI), encoding:signed 24-bit PCM.
I was visiting a studio recently and they were using Digital Performer and I asked him whether or not they were using 24-bit files and he said yes. And I know they were using AIFF. So 24-bit AIFF files are in use by studios these days.
If your Audacity workfile is 32-bit float, you can preserve the dynamic range of the audio by saving it in 24-bit AIFF. Thirty-two bit float uses a 24-bit mantissa and an 8-bit exponent. So, it is quite similar to 24-bit int format.
If someone with more mac and audacity experience is reading this, please chime in.
