Add a gentle pitch wobble or a wider vibrato effect. Adjust rate, depth and wet mix live, compare original audio and download the actual processed WAV.
No file selected.
Up to 128 MiB per file; decoded audio up to 256 MiB (about 23 min mono / 11½ min stereo). Formats depend on your browser's decoder. Working audio and WAV exports use 48 kHz.

Click the waveform to seek the source; use Play/Pause, exact time or jump controls. Vibrato changes apply live while playing. Duration stays unchanged; the waveform remains the original source. The source ruler always shows original source time.
Playback stopped.
Change settings while playing to hear vibrato live. Uncheck to compare original audio; exports always use the selected effect.
Quick sliders pause for exact values finer than their steps; your entered value remains usable.
The original file stays unchanged.
Input up to 128 MiB; source and output float audio each have a 256 MiB limit. Output keeps the source sample count. Live controls use a short smoothing transition and keep oscillator phase continuous. The source waveform stays unchanged; the generated waveform shows the actual effect.

48 kHz · 16-bit PCM WAV · original channel count and frame count. Sinusoidal fractional-delay modulation with cubic interpolation. No normalization or automatic tuning. Interpolation can change peaks; clipped samples are counted. Zero padding beyond clip edges can alter the last few milliseconds; no tail is appended. Tags/artwork are omitted. Inspect and listen to the actual exported result.
Your audio is never uploaded to any server. Decoding, vibrato processing, playback and WAV encoding happen entirely in your browser with self-hosted code. No account, external service or audio history is required.
Vibrato periodically varies pitch using sinusoidal fractional-delay modulation. Rate sets oscillations per second. Depth sets the nominal downward pitch deviation in cents, with 100 cents equal to one semitone. The upward deviation is slightly smaller; the expected full-wet pitch range is displayed. Duration and channel count remain unchanged.
100% wet plays the vibrato signal. Lower values blend the original sample with the modulated signal, which can sound chorus-like and cause phase cancellation or coloration. 0% wet or zero depth exports the unchanged decoded samples before WAV quantization. Stereo channels share modulation to preserve their timing relationship.
Yes. Rate, depth and wet mix update the playing local AudioWorklet without restarting it. A short smoothing transition reduces abrupt changes and oscillator phase remains continuous. Fixed-settings live playback and export use the same engine. The WAV export uses your current fixed settings, not a recording of live knob movements.
The full local source is available for fractional sample lookup, including around a seek position. Fixed-settings modulation is anchored to source time, so seeking does not restart its cycle. Samples outside the clip are zero-padded and no tail is appended; vibrato can alter or shorten the first/last few milliseconds. Source sample count and duration are retained. Live setting changes have phase/smoothing history that a fresh export does not reproduce.
It is a bounded browser vibrato effect using cubic interpolation, not a mastering guarantee. Strong depth, sharp transients or partial-wet blending can introduce coloration and resampling artifacts. No automatic tuning, formant correction, key/BPM detection, normalization or beat matching is included. Listen to the actual exported WAV.
Rate 0.5–12 Hz, depth 0–100 cents and mix 0–100%. One mono/stereo file up to 128 MiB, decoded at 48 kHz within a 256 MiB float-buffer limit. Output has its own 256 MiB float budget; device memory may impose lower limits. Live AudioWorklet needs a supported browser and HTTPS or localhost. Export is 48 kHz 16-bit PCM WAV; tags/artwork are omitted. Out-of-range output samples are clipped and counted. Stop export terminates its local worker.
