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 FLAC online free, no account required — FLAC is a lossless compressed audio format.
Change AMR to FLAC without losing quality — convert AMR to FLAC 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 FLAC
FLAC (Free Lossless Audio Codec) compresses audio without losing anything: the files are typically half to two thirds the size of WAV and decode back to the exact original samples.
Music archives, CD rips and high-resolution downloads.
FLAC files are several times larger than MP3, and some older players and car stereos do not play them.
Why convert CDs to FLAC instead of MP3? The copy is bit-for-bit identical to the original, so the archive never loses quality however often it is converted later.
What changes when you convert AMR to FLAC
- The audio is decoded and re-encoded as FLAC at the default settings, so the result is close to the AMR but not bit-identical.
- AMR is a lossy format and FLAC is not: the FLAC 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 FLAC, 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 FLAC file is kept for 2 hours, then deleted.
AMR to FLAC: questions and answers
Does converting AMR to FLAC reduce quality?
The audio is decoded and re-encoded as FLAC at the default settings, so the result is close to the AMR but not bit-identical. AMR is a lossy format and FLAC is not: the FLAC 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 FLAC?
AMR is a narrow-band speech codec from mobile phones. FLAC is a lossless compressed audio format.
Can I change the settings when converting AMR to FLAC?
Before you convert AMR to FLAC, 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 FLAC?
No. You can convert AMR to FLAC without an account; signing in raises the file-size and daily limits.
How long is my converted FLAC file kept?
The FLAC file you convert from AMR is kept for 2 hours, then deleted automatically.
Does converting AMR to FLAC restore the quality the AMR lost?
AMR is a lossy format and FLAC is not: the FLAC 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 FLAC, is the audio re-encoded?
The audio is decoded and re-encoded as FLAC at the default settings, so the result is close to the AMR but not bit-identical.
