Ok, it not work wit 32 bit float files. Just convert to 24b Type 1. Don't worry it is perfect to lossless: 32b = 24b + 8b (exponent to manipulate, not really important) ;)

See: http://en.wikipedia.org/wiki/Single_precision_floating-point_format

- Do you have problem to encode? Try to Disable Replaygain.
- I don't know why, but Once I had to disable the Add Tags to work...

what do you mean "you can not decode"?

Don't you understand how this works?

Encode your high quality wav files (direct CD rip) with flac, then you can play them with foobar2000 - absolutely no quality loss.

And, btw, NO your files will not be of better quality, when you encode your mp3 files to flac. You need to have highest quality for source material - mp3 is already crippled audio - it still sounds good, at least for non-musicians, but FLAC is for the elite studio guys.

mp3 means degradation and degeneration of your perception, it will kill your senses.

You will not understand this, when you are young today - you will understand, when you will be old, but then it will be to late.

If you really love music - USE FLAC!

cant decode doesnt even give any error while decoding dont you have GUI for these?!

I cant get it to decode anything. It just gives error messages. If anyone knows what is going wrong, please let me know.
