I'm looking for the best way to compare two audio files ,determine if they are same conversion, recorded by two different recorders.
I tried to use the VAD in Speex:
For testing, one audio file is a recording of the other , using the PC speakers.
Both are 8kHz, mono read in a 5 & 10 & 20 milliseconds buffers.
5 millisecond buffer - found the speech pauses more accurate, but the two outputs did not look the same.
20 millisecond buffer - ignored small speech pauses , but the outputs look more alike but not enough.
1. Is there any changes ( parameters /code) I can do to make results better for my needs ?
2. Do you know about any other algorithms which will be more suitable for my needs ?.
