When a recipient requests 24-bit WAV, checking the extension is insufficient. FileMyLove's current audio converter writes 16-bit PCM WAV. For mandatory 24-bit or 32-bit float delivery, export from an application that lets you choose the required settings.
WAV does not specify every setting
Mediabunny documents 16-bit, 24-bit and 32-bit float PCM as different codecs, with multiple variants supported inside WAV. A .wav extension alone therefore does not establish the required encoding.
FileMyLove chooses pcm-s16 in this path, documented as signed 16-bit little-endian PCM. Its audio-conversion interface currently has no manual bit-depth, sample-rate or channel-count selectors.
Do not confuse this with kbps
The bitrate choices shown for MP3 apply only to MP3. They neither make WAV 24-bit nor select a sample rate.
| Delivery requirement | What to inspect |
|---|---|
| WAV | The output file format |
| 16-bit or 24-bit | Recorded audio bit depth |
| Sample rate | Required versus resulting value |
| Mono or stereo | The required channel count |
Do not overwrite the original merely because an output plays successfully. Keep it available for another export.
Check before delivery
- Obtain the complete specification rather than just “WAV.”
- Inspect source audio properties in an application that reports them.
- If 16-bit WAV is appropriate, try a copy with Convert audio.
- Compare the resulting properties with the specification and listen near the start, middle and end.
- For other mandatory settings, return to the original in an application with suitable controls.
Processing stays in the browser without uploading audio. It does not certify compliance with every recipient's delivery standard.
Preserve the original separately
We recommend clearly separating source recordings from delivery copies. Do not automatically replace an original recording with this converted WAV, especially when the workflow depends on settings the website does not expose.
