Why AudioWrench
Less friction.
More finished audio.
The speed of a browser utility with the controls, previews and evidence expected from serious production software.
Private by design
Core file processing runs on your device, and selected files are not uploaded to AudioWrench. Normal page assets, optional model downloads and system-speech providers are disclosed in the privacy notice.
No installs, no setup
Open a tool, drop a file, tweak, download. Works on Windows, macOS, Linux, Android, iOS and Chromebooks.
Free to use
No subscriptions, watermarks or sign-ups. All 139 tools are free; each file workflow estimates memory from its algorithm, source and available device capacity instead of applying one arbitrary global cap.
Real DSP under the hood
Pitch-preserving time stretch, convolution reverb, spectral noise reduction, parametric EQ β the real thing, in JavaScript.
Built for creators
Viral speed effects, 8D spatial audio and bass boost tuned for TikTok, Reels and Shorts workflows.
Preview before download
Hear your changes in real time, fine-tune the settings, then export to MP3 (320 kbps) or WAV.
FAQ
Frequently asked questions.
Is AudioWrench really free?
Yes β every tool is free with no subscriptions, hidden fees, usage quotas or watermarks. Individual tools still have disclosed input, codec and device-memory limits.
Are my files uploaded anywhere?
Selected files are decoded and processed on your device and are not uploaded to AudioWrench. Normal page assets and optional AI code or model files can still be requested. Live system-speech mode may use a recognition service provided by your browser or operating-system vendor. See the exact data flow.
Which formats can I load?
Input support depends on browser codecs and commonly includes MP3, WAV, FLAC, OGG, M4A/AAC and some MP4, WebM or MOV files. Video audio is decoded and re-encoded, not losslessly extracted. Most tools export MP3 or WAV. File capacity depends on the toolβs algorithm, source duration and the memory available on the current device; each workflow reports its own preflight before processing.
How do I make the viral slowed + reverb sound?
Open the Slowed + Reverb tool, drop a song, pick the TikTok Slowed preset (80% speed, medium reverb), preview, then download. The Vaporwave and Nightcore Reverse presets are one click away too.
What's the difference between Sped Up and Nightcore?
Sped Up raises the tempo while keeping the original pitch, so vocals still sound natural. Nightcore raises speed and pitch together for the classic high-energy, high-pitched sound.
