UTF-8 is not supported natively in Windows. Your choices are MBCS or UTF-16 ("Unicode"). You'll need to convert your strings to UTF-8 manually whenever you need UTF-8. --Mike-- Visual C++ MVP :cool: LINKS~! Ericahist | PimpFish | CP SearchBar v3.0 | C++ Forum FAQ Hungarian notation FTW

The asnwer is that you must manually analyze the raw wave data stored in WAV file, either by fourier analysis or any other means. That is the way good WAV->MP3 converters work. ------------------------- Don't worry, be happy :o)

See this[^] article. As has already been pointed out, the resulting .WAV file will not be the original since MP3 compression is lossy. /ravi This is your brain on Celcius Home | Music | Articles | Freeware | Trips ravib(at)ravib(dot)com

The same APIs can do it but you still need an MP3 codec (the "dec"oder part of "codec") or you'd need to write your own. The APIs are available with the OS but the codec is not due to MPEG-3 licensing restrictions. Mark "If you can dodge a wrench, you can dodge a ball."

You don't need a library (you can write your own) if you know the WAV file format and the MP3 format/compression. Google may help :) "If you can dodge a wrench, you can dodge a ball."

Just search CodeProject for Convert To Mp3. Trinity: Neo... nobody has ever done this before. Neo: That's why it's going to work.
