listen should provide a way to specify sample rate

[sameermahajan]

listen API currently does not provide a way to specify sample rate. It seems that it uses some non standard sample rate / wave.getframerate() of 44100 which is making it difficult for me to process the wave file that I am trying to save and post process. Most wave processing packages look for frame rates like 8000, 16000, 32000, 48000
