AUDIOLIFT / A LITTLE MORE PRESENCE
Quiet clip.
Clearer handoff.
Bring a short WAV to a peak level you choose.
One careful adjustment. All on your device.
01 / BRING YOUR WAV
A small lift, not a full studio.
Integer PCM · mono or stereo · 8 / 16 / 24 / 32-bit
Under 50 MB, up to 5 minutes, at most 8 million total samples. Opening a file clears the previous workspace immediately.
Choose a local WAV or try the three-second synthetic tone. Nothing plays automatically.
02 / CHOOSE YOUR LEVEL
Keep some headroom.
−24 to −1 dBFS. Default −3 leaves sample-peak headroom. This is not a loudness or true-peak measurement.
Both channels receive the same multiplier, preserving their balance. Gain is capped at +60 dB; silence stays silent.
03 / OPTIONAL LISTENING CHECK
Compare, with volume lowered.
Lower your device volume first. The lifted version can be much louder. Both previews use the same playback volume and are converted to 16-bit WAV.
Listening is optional. No automatic playback.
Preview volume does not change the exported file. Headroom cannot guarantee safe listening levels on your equipment.
04 / KEEP YOUR RESULT
Your clip, ready for the next step.

Supported formats, privacy & beta limits
Little-endian RIFF/WAVE with exactly one PCM format chunk and one data chunk. Integer PCM only: 8, 16, 24 or 32-bit; mono or stereo; sample rates 8,000–96,000 Hz. Float WAV, WAVE_FORMAT_EXTENSIBLE, RF64, RIFX, MP3, AAC and other codecs are rejected. Unknown chunks are skipped; malformed, duplicate or truncated required chunks are rejected.
All limits apply together: file size under 50,000,000 bytes, duration at most 300 seconds, and at most 8,000,000 interleaved samples. At 48 kHz stereo the sample limit permits about 83 seconds. Parsing and export briefly run on the main thread. Browser memory behavior on low-memory devices has not been verified.
Peak normalization only: no noise removal, compression, LUFS normalization, resampling or repair of clipping in your source. Full-scale samples trigger a warning, not a diagnosis. A 16-bit export reduces precision from 24/32-bit sources; quantization is toward zero without dither so the exported peak never exceeds the calculated peak.
No application upload, analytics, browser storage or microphone access. Nothing is saved automatically. Downloads are not encrypted. Clear, replace or reload to release the current workspace. No real-browser decode, playback, device, visual-layout or accessibility acceptance testing has been completed for this beta.
Free beta. Your work stays local.
No account. No charge. No automatic saving. Audio is processed in this tab, not uploaded by the app. No app analytics or browser storage. If hosted, the hosting provider may receive normal access logs. Downloaded WAVs are unencrypted; clearing this page does not remove saved files.
Review exports before relying on or sharing them. Browser, device and accessibility acceptance checks remain pending; automated tests are not a guarantee of real-device behavior.
