I need to extract pitch, dynamics (loudness or softness), tone color, and duration of an audio file.
This is regarding some research work I am doing.
How should I start ? Provide me with some links if possible!

Is C++ a good option for this?
Or should I try some other language ....

Please Help!

Matlab would be a easier starting point. It already has many functions implemented for you to handle audio processing.
