Python Time & Space Complexity

Aifc

aifc Module¶

The aifc module provides support for reading and writing AIFF and AIFF-C audio files.

Complexity Reference¶

Operation	Time	Space	Notes
`open()`	O(1)	O(1)	Open file
Read/write frames	O(n)	O(n)	n = frame count

Working with AIFF Files¶

Reading Audio File¶

import aifc

# Open file - O(1)
with aifc.open('sound.aiff', 'rb') as f:
    # Get properties
    channels = f.getnchannels()
    width = f.getsampwidth()
    framerate = f.getframerate()
    frames = f.getnframes()

    # Read audio - O(n)
    audio_data = f.readframes(frames)

Writing Audio File¶

import aifc

# Create file - O(1)
with aifc.open('output.aiff', 'wb') as f:
    # Set properties
    f.setnchannels(2)        # Stereo
    f.setsampwidth(2)        # 16-bit
    f.setframerate(44100)    # CD quality

    # Write audio - O(n)
    f.writeframes(audio_data)
