audioop.lin2adpcm(fragment, width, state) Convert samples to 4 bit Intel/DVI ADPCM encoding. ADPCM coding is an adaptive coding
aifc.getframerate() Return the sampling rate (number of audio frames per second).
oss_mixer_device.reccontrols() Returns a bitmask specifying the mixer controls that may be used to record. See the code example
oss_mixer_device.get_recsrc() This method returns a bitmask indicating which control(s) are currently being used as a recording
aifc.aifc() Create an AIFF-C file. The default is that an AIFF-C file is created, unless the name of the file ends in '
aifc.tell() Return the current frame number.
aifc.getparams() Returns a
audioop.rms(fragment, width) Return the root-mean-square of the fragment, i.e. sqrt(sum(S_i^2)/n).
Wave_write.setparams(tuple) The tuple should be (nchannels, sampwidth, framerate, nframes, comptype, compname)
aifc.getcompname() Return a bytes array convertible to a human-readable description of the type of compression used in the audio
