PCM-Beispieldateien

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.

Validation Methodology
  • Verify duration, sample rate, and channel count in your decoder.
  • Test metadata extraction and malformed-tag handling.
  • Validate seek/stream behavior over slow networks.
