1 Answer1. Show activity on this post. I have done this sort of thing in my undergrad course project but with image files. The thing you would want to look into is Cross-correlation. In which you can measure similarities between two signals. Also you might want to preprocess the audio files ie: normalize, apply some low pass filter to remove noise.

Identifying the frequency components of each audio signal is crucial for audio comparison. The time-domain signal is difficult to inspect and must be converted to its frequency-domain equivalent before analysis can be performed. Our software utilizes an algorithm that produces an estimate of the audio signal's frequency content to compose the ...

Analog signals are more accurate than digital signals. Digital signals are less accurate. Analog signals take time to be stored. It has infinite memory. Digital signals can be easily stored. To record an analog signal, the technique used, preserves the original signals. In recording digital signal, the sample signals are taken and preserved.
