What is aifc.getmarkers() in Python?

AIFF, which represents Audio Interchange File Format, is an audio file format standard used for storing sound data for personal computers and electronic audio devices. The format was created by Apple Inc. in 1998.

Because of the failure of AIFF, the AIFC or AIFF-C was created. The AIFF record utilizes considerably more circle space than lossy organizations like MP3, about 10MB briefly of sound system sound at an sample rate of 44.1kHz and a bit profundity of 16 pieces. Then again, the AIFC can pack the sound information…

Sound documents have various boundaries that portray the sound information, which are:

  1. Sampling rate or frame rate: This is the number of times each second the sound is examined.

  2. Number of channels: This demonstrates if the sound is mono, stereo system, or quadro.

  3. Frame: A frame comprises of one sample for every channel. In this way, a frame is comprised of the quantity of channels multiplied by the example size in bytes. A second worth of audio is comprised of the number of channels multiplied by sample size and by frame rate bytes.

  4. Sample size: The sample size is the size in bytes of each sample.

For instance, CD quality sound has a sample size of two bytes (16 pieces), utilizes two channels (sound system), and has an frame rate of 44,100 frames each second. This gives a frame size of 4 bytes (2 * 2), a subsequent’s worth possesses 2244,100 (176,400) bytes.

The aifc module defines some methods (functions) for working with the objects. The instance is made as follows:

aifc.open(file, mode=None)

Among the characterized capacities for working with an instance, aifc.getmarkers().

The first is a number ID, the second is the identified position in frames from the start of the data (a number), and the third is the name of the mark (a string). Markers are utilized to identify a significant event in a video or sound record so the event can be addressed rapidly later on.

import aifc
obj = aifc.open('sample4.aiff','wb')
print('following are the markers in the audio file: ', obj.getmarkers())
in[30]:runfile('c:/user/macair/.spyder/marker.py)
wdir='c:/user/macair/.spyder' following are the marker in the audio file: [(1, 1000, b'foo'])
