Про конвертацію AIFF у AMR
AIFF stores studio-quality uncompressed PCM audio, while AMR (Adaptive Multi-Rate) is a narrowband speech codec running at 4.75-12.2 kbps. This conversion represents one of the most extreme compression ratios in audio: from 1,411 kbps (CD-quality AIFF) down to 12.2 kbps AMR-NB, a 115:1 ratio. The output is designed exclusively for telephony — voicemail, IVR systems, and cellular voice transmission.
Навіщо конвертувати AIFF у AMR?
Telecom infrastructure worldwide runs on AMR. When studio-recorded voice prompts (IVR menus, hold music announcements, automated greetings) need to be loaded into a telephone switch, PBX, or voicemail platform, they must be in AMR format. The extreme compression makes AMR ideal for transmission over 2G/3G cellular links where bandwidth is measured in kilobits.
