  • IMA ADPCM Compression (4 bits per sample)
  • Input: 16 bits PCM sound samples
  • Mono: one channel operation
  • Output includes standard WAV headers
  • Selectable sample rate of recording

Output compatible with any sound player with the IMA ADPCM codec (included by default in every Windows). Includes a testbench that takes an uncompressed PCM 16 bits Mono WAV file and outputs an IMA ADPCM compressed WAV file.

As per the IMA-ADPCM standard, the compression ratio is 4:1.
