Are there libraries for extraction of sound wave features?
From the ones I've been using I can recommend:


YAAFE - very pleasant to work with in Python
ESSENTIA - another one I like particularly due to Python integration
aubio
FEAPI
Aquila - friend of mine used it extensively and he likes it a lot




Recently I came across this paper and I believe that this should perfectly answer your question. 


  Moffat D. et al - An Evaluation of Audio Feature Extraction
  Toolboxes


They do provide a detailed comparison based on:


Amount of features available
Ease of usage
Output format of the features
Computational efficiency


They tested following libraries:


Aubio
Essentia
jAudio
Librosa
LibXtract
Marsyas
Meyda
MIR Toolbox
Timbre Toolbox
YAAFE
