What is PCM?
Pulse-Code Modulation (PCM) is the standard form of digital audio used in computers, compact discs, and digital telephone systems. It represents the sampled amplitude of the audio signal at uniform intervals, providing a direct digital representation of the analog waveform. As the fundamental building block of digital audio, PCM ensures that the signal is captured with high fidelity without the initial loss associated with compression algorithms.
Unlike compressed formats such as MP3 or AAC, PCM stores raw audio data without discarding any information. This uncompressed nature makes it the preferred choice for professional recording, editing, and archiving where audio quality is paramount. While the file sizes are significantly larger than compressed alternatives, the integrity of the sound remains intact from the source to the final output.
PCM is widely supported across virtually all hardware and software platforms, serving as the backbone for many container formats like WAV and AIFF. Its universal compatibility ensures that audio engineers and consumers alike can access and manipulate the data without proprietary restrictions. Whether used in high-resolution music production or standard CD playback, PCM remains the gold standard for digital audio representation.
