AMR File Converter

The AMR codec uses a combination of linear predictive coding and algebraic code-excited linear prediction to compress audio. It achieves compression by exploiting the repetitive patterns in human speech, resulting in lower file sizes without sacrificing intelligibility. The format is designed to handle narrowband audio sampled at 8 kHz. AMR's efficiency and low latency make it ideal for real-time voice transmission.

AMR files typically store encoded speech and are often used in telecommunication systems and mobile devices. The codec supports multiple bit rates ranging from 4.75 to 12.2 kbps, allowing it to adapt to changing network conditions. This flexibility helps maintain understandable voice communication even in poor signal areas. The AMR format is widely supported by many audio players and conversion tools.
