Giới thiệu về chuyển đổi AMR sang ALAC
AMR is a speech-only codec standardized by 3GPP for mobile telephony, encoding at bit rates as low as 4.75 kbps. ALAC (Apple Lossless Audio Codec) is a lossless compression format developed by Apple, capable of reducing PCM audio to about 50-60% of its original size without losing a single sample. Converting AMR to ALAC gives you an Apple-native lossless file that is smaller than AIFF or WAV while remaining perfectly reconstructible.
Tại sao nên chuyển đổi AMR sang ALAC?
If you want an uncompressed-equivalent archive of a voice recording that plays seamlessly in Apple Music, iTunes, and all iOS/macOS apps, ALAC is the best choice. Unlike AAC, ALAC is mathematically lossless — you can decode it back to the exact PCM stream that came out of the AMR decoder. It is also smaller than AIFF/WAV, making it practical for archiving large collections of call recordings on Apple hardware.
