AMR to WAV Conversion FAQ
What bitrate does the WAV file end up at?
+
A lossy WAV is encoded at 192 kbps by default. The Audio Quality setting also offers 320 kbps for the best quality and 128 kbps for a smaller file. A lossless WAV (WAV, FLAC) ignores the bitrate and keeps every sample.
Does converting AMR to WAV improve the audio quality?
+
No, and it is worth being blunt: nothing can. The AMR already discarded detail during its original encode, and wrapping what remains in a lossless WAV preserves exactly that — no more. The file gets several times larger and sounds identical. It is still the right move before editing, because WAV will not add a second generation of artefacts when you export. WAV is the correct format for editing, mastering and archiving, because it can be re-encoded any number of times without accumulating artefacts. AMR destroys music: its 8 kHz bandwidth removes everything above telephone frequencies, and no amount of re-encoding brings it back.
Why does music sound so poor in this conversion?
+
Because one side of it is a speech codec rather than a music codec. It models the human vocal tract and discards everything outside telephone bandwidth, which is fine for a voice memo and destructive for anything with instruments in it. Converting away from it cannot restore the missing frequencies — they were never encoded in the first place.
Will going from AMR to WAV actually reduce my audio quality?
+
If AMR is lossy (MP3, AAC) and WAV is lossless (WAV, FLAC), the WAV is no better than the AMR — you cannot recover information already discarded by the lossy AMR codec. If AMR is lossless and WAV is lossy, expect the WAV encoder to recompress; at 192 kbps the loss is imperceptible to most ears.
Can I batch-convert hundreds of AMR files into WAV?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Can I normalize loudness in the AMR to WAV step?
+
Not in this step. The converter has no loudness setting and leaves the level as it is. To even out the volume, run the finished WAV through a Normalize tool on this site.
Will the WAV play on my car stereo / iPod / Sonos / Bluetooth speaker?
+
MP3 plays almost everywhere. AAC plays on Apple devices, most Android phones and Sonos. FLAC plays on Sonos and Android but not on older iPods, and WAV plays on nearly everything but makes large files. There are no device presets on this page, so choose the target format your player supports. WAV is enormous — roughly 10 MB per stereo minute at CD quality — and the classic format has a 4 GB ceiling and no room for proper tags.
Is my AMR file private during conversion?
+
Yes. Uploaded AMR files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted WAV are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
How long does converting a 1-hour AMR to WAV take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
