IMA ADPCM in het kort
IMA ADPCM
Convert to IMA ADPCM when a workflow needs compact audio with very cheap decoding, such as older game engines, embedded devices, telephony-adjacent systems, or legacy multimedia runtimes.
It is a practical target where playback efficiency matters more than modern codec quality.
CAF in het kort
CAF
Convert to CAF when working inside Apple audio pipelines, especially for long recordings, app assets, sound libraries, or technical workflows that benefit from Core Audio compatibility.
It is a good target when AIFF or WAV limitations are inconvenient but Apple tooling is the primary consumer.
For general exchange, WAV, AIFF, or M4A are usually easier handoff formats.
