PCM voorbeeldbestanden

PCM (.pcm) files contain raw, unformatted audio samples in Pulse Code Modulation. Used in embedded systems and DSP applications, they require external metadata (sample rate, bit depth). Use sample .pcm files to validate low-level audio processing, buffer alignment, and format conversion.
