I've been a fan of ffmpeg since I discovered it (around version 0.4). In the current version (2.0), OpenCL has been included. OpenCL has made it quite a bit faster. (Pun intended)
Something I'd like to do is the following:
1) Choose the WMA file you'd like converted:
2) Choose the output file specs:
3) Enter your email, so the finished file can be sent/downloaded:
4) Made a mistake? Click Start Over. Ready to go? Click Done, upload audio file.
When your file is uploaded, I will then use ffmpeg to convert your file with the settings you specified. The converted file will then be uploaded to the site (and email sent with a link), ready for you to download and enjoy.
