Hi all 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. The results: 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 ?.
