Hello I would need way to check the amplitude (over time) for a sound file in python. I'm sure this can be done, for example the audioop.rms function seems to be able return amplitude values. However, it would be really great to get the results in dB, which does not seem to be the case. Anyone who has more information about this, or a way to convert the results? I've searched google but info about audioop seem to be quite scarce. Also, does audioop function perfectly also for wave files? Also, cross-platform solutions are of course preferred, but I'm running linux (with oss).
I've also looked somewhat into tkSnack (http://www.speech.kth.se/snack/) which has a dBPowerSpectrum function which might be doing at least partially what i want it to, however, the returned values are approx. -100 ... which I find odd. The "real", recorded sound was somewhere in the 50-60dB range. thanks in advance -- http://mail.python.org/mailman/listinfo/python-list
