Frequently Asked Questions
IMA ADPCM is the standard codec for embedded audio, game consoles, and telephony devices. It achieves 4:1 compression with very low decode complexity.
Embedded systems, retro game consoles, voice recorders, and industrial audio equipment that need simple, fast audio decompression.
IMA ADPCM compresses audio to one quarter of WAV PCM size while being trivial to decode — perfect for resource-constrained hardware.
Yes — IMA ADPCM discards some audio detail during encoding. Quality is adequate for voice and sound effects but not ideal for music.
Upload a batch of WAV files and produce IMA ADPCM data for each one simultaneously — ideal for firmware audio assets.
