CVU to WAV Converter
Processing entirely on your device — large files may take a moment.
WAV is required by most video/audio editing tools as the cleanest import format. If your files are still in CVU format, this page is the shortcut: CVU is unfiltered Continuously Variable Slope Delta modulation — the raw codec behind early voicemail and Motorola telephony boards.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the CVU format
CVU is unfiltered Continuously Variable Slope Delta modulation — the raw codec behind early voicemail and Motorola telephony boards.

- −Legacy niche format
- −Modern tools rarely open it
- −Keep the original for archival round-trips
About the WAV format
WAV is the simplest possible audio file: PCM samples — the raw digits of the waveform — inside a RIFF container. CD-quality stereo (44.1 kHz, 16-bit) runs about 10 MB per minute, and studio work uses 24-bit/48–96 kHz without blinking. Every DAW, every interface and every phone records to it; nothing about it can be misinterpreted.
That perfection is why WAV remains the format of recording and editing: every sample is bit-exact, so processing, slicing and mixing never fight artifacts. And it is why nobody streams it — ten megabytes a minute is storage money, not delivery.
+ Strengths
- ✓Bit-perfect, zero-loss audio
- ✓The editing and recording standard
- ✓Supports hi-res depths and sample rates
! Limitations
- −Enormous files (~10 MB/minute at CD quality)
- −Tagging is an afterthought (BWF fills the gap)
- −Impractical for streaming or phones-on-the-go libraries

There is a concrete reason this conversion exists: Legacy niche format WAV sidesteps that — Bit-perfect, zero-loss audio If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this CVU to WAV converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for CVU to WAV?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Can I convert a whole folder of CVU files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
Will converting CVU to WAV reduce audio quality?
If WAV is lossless, the output contains everything the CVU file contains — no further loss is added. If WAV is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
