M4A kisaca
M4A
Convert to M4A when you need a compact, modern audio file for music, podcasts, lectures, or spoken-word distribution with strong playback support and good metadata handling.
It is an excellent target for listening copies and portable libraries.
For raw editing or mastering, uncompressed or lossless production formats remain better choices.
AMR kisaca
AMR
Convert to AMR when the target is a speech-oriented mobile or telephony workflow, such as voicemail systems, call recordings, or compatibility with older handset ecosystems.
It is useful when bandwidth and voice intelligibility matter more than music quality.
For music or general listening, AAC, Opus, or WAV are better targets.
