Om konvertering fra FLAC til AMR
AMR (Adaptive Multi-Rate) is a narrowband speech codec standardized by 3GPP, operating at bitrates between 4.75 and 12.2 kbps. It was the backbone of GSM and 3G voice calls for over a decade. Converting FLAC to AMR is a dramatic compression — from lossless CD-quality audio down to telephone-grade speech encoding. This conversion only makes sense for very specific scenarios involving legacy telephony systems, feature phones, or embedded devices that require AMR input.
Hvorfor konvertere FLAC til AMR?
AMR remains the mandatory speech codec for GSM networks and many VoIP gateways. Certain IVR (Interactive Voice Response) systems, automated calling platforms, and legacy voicemail systems accept only AMR-encoded audio. Converting FLAC recordings of voice prompts, announcements, or instructional content into AMR ensures compatibility with these older but still-operational telephony infrastructures.
