What is the best audio format to upload in. Server will convert to mp3 and ogg

Question

Which audio format would provide the least lossy conversion into mp3 and ogg through ffmpeg.

I am tending towards wav, but I would like to make sure.

Also, I am using the SDK java audio applet to allow users to upload. Does anyone know if there are any issues with this applet, or if there is a better option out there?

Answer 1

Obviously, uploading files already in MP3 and OGG format would provide the least lossy conversion since you don't need to convert at all.

About the SDK java audio applet: Is this really needed? You can also upload a file using just a HTML form and PHP.

Answer 2

FLAC is lossless, and so is WAV. FLAC is smaller than WAV. If you need something that you will be converting into multiple formats, opt for a lossless format.
