aifc.getcomptype() is a module that provides support for writing and reading AIFF and AIFF-C files. This module carries out its functions by returning a bytes array of length 4 describing the compression type of the AIFF-C files.

The mode is r or rb when the file is opened for reading, or w or wb when the file is opened for writing. When omitted, file.mode is used if it exists, otherwise rb is used.

Audio Interchange File Format, or AIFF, is a file format that stores digital audio samples.

While AIFF-C is a newer version of the format that can compress the audio data, the AIFF file default has a compression type of b’NONE’, as it cannot be compressed.

Several parameters describe audio data. They are:

  • The frame rate
  • Sampling rate: defined as the number of times per second a sound is sampled.

Sample size is the size of each sample in bytes. A frame consists of one sample per channel. Hence, a frame consists of (nchannels * samplesize) bytes, and a second’s worth of audio consists of (nchannels * samplesize * framerate) bytes.

The number of channels in the frame indicates if the audio is mono, stereo, or quadro.

The difference between monophonic sound and stereophonic sound is the number of channels that are used to record and playback the audio.

Furthermore, the aifc.open() function opens an AIFF or AIFF-C file and returns an object instance with a method. The file passed in as an argument is either a string naming or a file object.

import aifc
obj = aifc.open('sample.aif','rb')
print(f"The compression type of the audio file is : ", obj.getcomptype())
