Σχετικά με τη μετατροπή MOV σε AMR
MOV files from Apple devices store high-quality audio (typically AAC at 128-256 kbps stereo) alongside video. AMR (Adaptive Multi-Rate) is a narrowband speech codec developed by Ericsson for GSM cellular networks, encoding voice at 4.75-12.2 kbps mono at 8 kHz sample rate. It was the standard voice format for 2G/3G telephony worldwide.
Γιατί να μετατρέψετε MOV σε AMR;
AMR's extremely low bitrate makes it ideal for voice content that needs to be as small as possible — voice notes, dictation, and telephony applications. A 1-minute voice recording in AMR is roughly 100 KB compared to 1-2 MB for the same content in AAC. This matters for MMS messaging, low-bandwidth networks, and embedded systems with minimal storage.
Some voicemail systems and legacy PBX platforms still require AMR input, making this conversion relevant for business telephony workflows.
