Are there any libraries for channel inversion?

I am trying to compensate for channel effects introduced into a waveform received over a mobile channel and the same waveform when received over a landline channel. Are there any libraries/code out there that do any one of the following:

1. Sound Equalizatio开发者_StackOverflown

2. Channel inversion/normalization

I have looked over the Internet and found nothing much. Any help is most welcome.

The libraries, if they exist, can be in any language, c/C++/Java/Python ... anything.

In general, it's impossible to compensate for a lossy or noise additive channel, which a mobile codec usually implements.
