What Is PCM Audio?

Explanation

PCM stands for Pulse Code Modulation, which is a method used to digitally represent analog signals. In the context of audio, PCM is the standard method for storing and transmitting uncompressed audio data. It is the most common format used in digital audio systems, including CDs, DVDs, and digital audio files.

PCM works by sampling the analog audio signal at regular intervals and converting each sample into a digital value. These digital values are then stored as a series of numbers that represent the original audio waveform. When the audio data is played back, the digital values are converted back into analog signals, which can be amplified and played through speakers or headphones.

What Is Known About PCM Audio

PCM audio is widely used in professional audio production and is known for its high fidelity and accuracy in reproducing sound. It is a lossless format, meaning that no data is lost during the encoding and decoding process. PCM audio files can be of different sample rates and bit depths, with higher values resulting in better audio quality but larger file sizes.
