O převodu WebM na AMR
WebM files contain audio encoded with Opus or Vorbis — codecs capable of excellent broadband audio quality. AMR (Adaptive Multi-Rate) is a narrowband speech codec operating at 4.75-12.2 kbps, mono, 8 kHz — designed for GSM cellular voice calls. The quality gap between Opus and AMR is enormous.
Proč převádět WebM na AMR?
AMR produces the smallest possible audio files — about 90 KB per minute. This extreme compression is useful only for speech content when audio must be delivered via MMS, legacy voicemail systems, or IVR telephony platforms with strict AMR format requirements.
The conversion extracts and radically compresses audio from web video sources for telephony applications.
