Tentang Konversi VOB ke AMR
DVD VOB files contain high-quality audio (AC3, DTS, or LPCM) designed for home theater systems. AMR (Adaptive Multi-Rate) is a narrowband speech codec operating at 4.75-12.2 kbps, mono, 8 kHz — designed for GSM cellular voice. The quality gap between DVD audio and AMR is enormous, making this conversion appropriate only for speech content.
Mengapa Mengonversi VOB ke AMR?
AMR produces the smallest possible audio files — about 90 KB per minute. This extreme compression is useful only for extracting speech-only content (dialogue, commentary, lectures) from DVDs when the audio needs to be delivered via MMS, legacy voicemail, or IVR systems with strict format requirements.
The conversion reduces DVD audio quality to telephone-grade, which is acceptable for speech recognition and transcription pipelines that do not require high fidelity.
