3GA in sintesi
3GA
Convert to 3GA when the destination is a mobile or telephony-oriented workflow that expects compact phone-friendly audio recordings.
It is useful for preserving compatibility with handset voice notes, legacy messaging systems, and archives of older device captures.
For broad playback and library management, M4A, MP3, or WAV are usually more convenient targets.
AMR in sintesi
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.
