python - How to get audio spectrum analysis? - Software ...
https://softwareengineering.stackexchange.com/questions/179607/how-to-get-audio-spectrum-analysis
I need to find or create a tool that analyzes the audio spectrum of a sound file (like a .wav or .mp3). I need to output the "volume" or power of x number of frequency bands and output the data as text. This will be used to produce a visualization, a graphic equalizer like you'd see on a stereo. I am currently looking at python to do it.
