What C ++ libraries should I look for if I want to change the sound file and save it back?

I am looking for some tips for sound related libraries for C ++.

My requirements are as follows:

  • upload a sound file - this means that I need to know what type of sound is being input, and then deal with it. For example, an MP3 file must first be decoded before further processing.

  • Changing the sound - we should be able to play with the whole sound file. I mean, for example, the ability to accurately determine the period of time (for example, 10.25 seconds of this sound), moving part (for example, from 10 to 20 seconds) of the sound around, etc.

  • save the sound file back to disk - after we process a respected sound, we must save the sound back to disk.

I am new to this area, so honestly I don’t know where and how to approach. If you know how to approach sound programming, please help me. Many thanks.

FYI, I use both Windows and Mac.

Audacity is a leading open source editor and recorder. This is a cross platform and C ++, and looking at the source code should give you an idea of ​​how to do this. It is licensed under the GPL, so you cannot directly use its source.
