Pulse Code Modulation (PCM)

Pulse Code Modulation (PCM) in Casio Keyboards

Pulse Code Modulation (PCM) is a digital audio encoding method used in many Casio keyboards. PCM technology allows for high-quality sound reproduction by converting analog audio signals (like the sound of a piano or drum) into digital data.

This process involves sampling the audio waveform at regular intervals, quantizing these samples, and then storing them as binary data (1s and 0s). The result is a faithful reproduction of real instrument sounds.

PCM in Casio keyboards provides a rich and authentic audio experience, making it ideal for musicians who want realistic sounds.

Casio uses PCM to store high-quality samples of real instruments like pianos, guitars, and drums, which can then be played back on the keyboard.

PCM Process Breakdown:

Sampling: The original sound is recorded at regular intervals (sampling rate), capturing snippets of the audio.
Quantization: The captured samples are converted into discrete digital values.
Encoding: These values are encoded into binary form for storage or playback.
Playback: When a key is pressed, the digital data is converted back into an analog signal, producing sound through the speakers.

Casio’s use of PCM ensures that even in compact keyboards, the sounds are clear, accurate, and true to life.
