compare audio files programatically
Posted on 2013-12-05
Hi everyone, I'm looking for a solution to compare audio files of voice recordings.
One file will be recorded in the studio.
Users are asked to imitate that recording as adequately as possible.
We need to compare each user recording to the original, and determine programatically, preferably using server side scripting (php or node.js), which ones are most similar to the original.
I was thinking we could make a spectrogram out of each recording and compare the bitmap data looking for similarities. I guess there must be other ways of doing this.
Tips & Tricks are more than welcome !
