Audio Processing - Tone Recognition [duplicate]

问题:

This question already has an answer here:

• Real-time pitch detection using FFT [closed] 3 answers

I've started developing a simple guitar tuner as a learning project for audio processing programs.

Could someone recommend me an adequate library for this? Here's basically what I'm looking for:

• Microphone input.
• Real-time processing of the signal. I need to be able to perform note recognition on whatever is being played to the mic.
• Cross platform/open source would be a huge plus.
