title: Calculation of fft using python
body: <p>By using <code>wave</code> in Python we can read .wav audio format and can calculate the frequency and power of a signal. But I want to calculate the frequency of .mp3 audio format directly. I've heard a little bit about Pysox. Is Pysox capable of reading frames and can we calculate the fft and frequency using Pysox? Or is there any other software which can calculate the frequency of an MP3 file using Python?</p>
