AC3 to WAV Conversion FAQ
What bitrate does the WAV file use?
+
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 AC3 to WAV improve the audio quality?
+
No, and it is worth being blunt: nothing can. The AC3 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. AC-3 is inefficient by modern standards and is not accepted by browsers, phones or most web players without a downmix to stereo.
Will going from AC3 to WAV reduce my audio quality?
+
If AC3 is lossy and WAV is lossless (e.g. MP3 → WAV), the WAV file is no better than the AC3 — you can't recover information that's already been thrown away. If AC3 is lossless and WAV is lossy, expect the WAV codec to recompress; at 192 kbps this is transparent for most content.
Can I batch convert hundreds of AC3 files to 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.
Will the WAV keep the same sample rate as AC3?
+
By default yes (48 kHz AC3 → 48 kHz WAV). If you need to downsample for compatibility (e.g. 96 kHz → 44.1 kHz for CD burning) the advanced sample-rate option does this with high-quality resampling.
Can I normalize loudness in the AC3 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 / audiobook app?
+
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.
Is my AC3 file private during conversion?
+
Yes. Nobody listens to or shares the audio, which matters for personal audiobook libraries, and uploaded AC3 files and their converted copies are deleted automatically about 24 hours after conversion.
How long does converting a 10-hour audiobook AC3 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.
Why is the WAV file louder / quieter than the AC3 source?
+
The converter does not change the level: it has no gain or normalize setting. If you hear a difference, your player or media library is probably applying ReplayGain or its own volume levelling on playback; switch that off to hear the WAV as it is.
