What are the best affordable c++ audio libraries?

Question

I'm looking for a c++ audio library that can play mp3s and mix audio. I can spend some money on it, but I'm on a somewhat tight budget, so the less the better. It really needs to just run on Windows and Mac OS X although Linux and embedded devices are a big plus. Anyone know of a good library or two?

Thanks!

Answer 1

Have you looked at libavcodec? seems like it would be what you are after. You are able to grab it from the ffmpeg site.

Answer 2

I'd have a really close look at sox. It's excellent. We're using the sox C++ library to do real time transformation of RTP streams. Works well.

Answer 3

JUCE is an awfully nice portable toolkit for graphics and audio. The main architect created it for real time audio processing, but it's evolved into a wider range of tools.

Answer 4

No firsthand experience, but PortAudio is highly recommended.

Answer 5

Though it does do ten zillion more things that you don't mention, I can't fail to recommend Qt with Phonon -- I learned about it only earlier today (from another Q&A on SO!) and it's opening new frontiers for me. If you need even a tiny fraction of the incredible power of Qt, that's definitely something worth trying (LGPL, so free and unencumbered as long as you don't modify the library itself).
