About AMR and AAC
AMR: AMR is a speech codec made for mobile phones. Older Android and Nokia phones, call recorders and voice-memo apps save recordings as .amr files, which many computers cannot open.
AAC: AAC is the successor to MP3 and the audio codec behind YouTube, iTunes and most streaming services. A .aac file stores the raw AAC stream without an MP4 wrapper.
