Convert AMR to Lossless WAV Format
Narrowband (8 kHz sampling rate) sounds hollow and tinny; designed strictly for speech, unusable for music. Converting to WAV gives you a key advantage: completely uncompressed pcm audio — the raw digital representation of sound with no processing or quality loss whatsoever. WAV is best for professional audio production, recording studios, and sound design where zero quality loss is mandatory.
Why Convert AMR to WAV?
Narrowband (8 kHz sampling rate) sounds hollow and tinny; designed strictly for speech, unusable for music — converting to WAV overcomes this by providing completely uncompressed pcm audio — the raw digital representation of sound with no processing or quality loss whatsoever
WAV is the right choice when you need to: recording and mixing music in professional daws (pro tools, logic pro, ableton)
Gain broader compatibility — WAV works with Universal — Windows, macOS, Linux, all DAWs, all browsers, all audio hardware
Prevent further quality degradation — once converted to WAV, no additional data is lost on re-saves

Frequently Asked Questions
Will converting AMR to WAV improve my file's quality?
expand_more
No — converting a lossy AMR to lossless WAV preserves exactly what you have, but cannot restore data already discarded by AMR compression. The benefit is that no further quality is lost on subsequent edits and re-saves.
How large will my WAV file be compared to the original AMR?
expand_more
AMR files are typically 10 KB – 2 MB, while WAV files are typically 10 MB – 100 MB per minute. The actual size depends on content complexity and any quality settings you choose.
What software can open the converted WAV file?
expand_more
WAV is compatible with: Universal — Windows, macOS, Linux, all DAWs, all browsers, all audio hardware.
What is the maximum file size I can convert?

What's the difference between AMR and WAV?
expand_more
AMR (Adaptive Multi-Rate Audio) is best for voice recordings from mobile phones, especially mms voice messages and gsm network audio. WAV (Waveform Audio File Format) is best for professional audio production, recording studios, and sound design where zero quality loss is mandatory. Key tradeoff: AMR's advantage is extremely compact voice encoding — a 1-minute voice memo is only about 60 kb at 4.75 kbps, while WAV's advantage is completely uncompressed pcm audio — the raw digital representation of sound with no processing or quality loss whatsoever.
Pro Tips for AMR to WAV Conversion
WAV preserves full quality, so your output file will be as good as the AMR source — no need to worry about compression artifacts
Keep a backup of your original AMR file — while our conversion is reliable, having the source is always recommended
WAV works especially well for: providing sound effects and samples for game development and film post-production
Did you know? WAV files use the same RIFF container as AVI video files — technically, you could embed a WAV audio track inside an AVI file using the exact same binary structure.
