What is a PCM File?

PCM, short for Pulse-Code Modulation, is a standard method for digitally representing analog signals. It is often used for uncompressed audio in formats like WAV and AIFF.

Key Advantages of PCM Files:

Uncompressed Quality: PCM retains the exact waveform of the original analog audio signal, ensuring high fidelity.

Simple Encoding: PCM is straightforward to encode and decode, making it widely compatible with audio processing software and hardware.

Lossless: PCM does not compress audio data, preserving audio quality without any loss or artifacts.

Limitations of PCM Files:

Large File Sizes: Uncompressed PCM files can be very large, which may not be practical for storage or distribution without compression.

Compatibility: While widely supported, PCM's uncompressed nature may limit its use in scenarios requiring efficient storage or transmission.


PCM is ideal for scenarios where maintaining the highest audio quality is crucial, such as in professional audio production and archiving.
