About AMR
AMR (Adaptive Multi-Rate) is a speech codec designed for mobile networks; its narrow-band form codes voice at 4.75 to 12.2 kbit/s.
Voice notes and call recordings from older phones and dictation apps.
AMR keeps only the frequency range of speech, so music in an AMR file sounds poor, and converting it cannot bring the missing range back.
Convert AMR to ALAC online free, no account required — ALAC is Apple's lossless audio codec.
Change AMR to ALAC without losing quality — convert AMR to ALAC free in your browser.
Why do my recorded calls sound so tinny and robotic? AMR was designed to squeeze narrow-band speech over 2G networks, so it discards almost everything but the voice — no conversion can restore the missing range.
About Apple Lossless (ALAC)
Apple Lossless (ALAC) is Apple's lossless audio codec, usually stored in an .m4a file; Apple released it as open source in 2011.
Lossless music in iTunes, Apple Music and on iPhones.
ALAC files are smaller than WAV but several times larger than AAC, and many devices outside Apple's prefer FLAC.
Why convert a CD to ALAC? You keep every sample of the original at half the WAV size, and it syncs and plays inside the Apple ecosystem untouched.
What changes when you convert AMR to ALAC
- The audio is decoded and re-encoded as ALAC at the default settings, so the result is close to the AMR but not bit-identical.
- AMR is a lossy format and ALAC is not: the ALAC keeps the decoded AMR exactly, but it cannot restore detail the AMR compression already removed, and the file is usually larger.
Settings you can change
Before you convert AMR to ALAC, you can adjust: Audio codec, Rate control, Audio bitrate, Quality (VBR), Sample rate, Channels, Normalize loudness, Trim start, Trim duration, and Keep tags.
Limits
Each plan sets a maximum file size and a number of conversions per day, and video and audio files also have a maximum length. Guests can convert files up to 100 megabytes and 5 per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your converted ALAC file is kept for 2 hours, then deleted.
AMR to ALAC: questions and answers
Does converting AMR to ALAC reduce quality?
The audio is decoded and re-encoded as ALAC at the default settings, so the result is close to the AMR but not bit-identical. AMR is a lossy format and ALAC is not: the ALAC keeps the decoded AMR exactly, but it cannot restore detail the AMR compression already removed, and the file is usually larger.
What is the difference between AMR and ALAC?
AMR is a narrow-band speech codec from mobile phones. ALAC is Apple's lossless audio codec.
Can I change the settings when converting AMR to ALAC?
Before you convert AMR to ALAC, you can adjust: Audio codec, Rate control, Audio bitrate, Quality (VBR), Sample rate, Channels, Normalize loudness, Trim start, Trim duration, and Keep tags.
Do I need an account to convert AMR to ALAC?
No. You can convert AMR to ALAC without an account; signing in raises the file-size and daily limits.
How long is my converted ALAC file kept?
The ALAC file you convert from AMR is kept for 2 hours, then deleted automatically.
Does converting AMR to ALAC restore the quality the AMR lost?
AMR is a lossy format and ALAC is not: the ALAC keeps the decoded AMR exactly, but it cannot restore detail the AMR compression already removed, and the file is usually larger.
When I convert AMR to ALAC, is the audio re-encoded?
The audio is decoded and re-encoded as ALAC at the default settings, so the result is close to the AMR but not bit-identical.
