    TikTok slowed and reverb maker

    Build a slowed soundtrack for a video edit

    TikTok Slowed starts with a slower, deeper and more reverberant version of your audio: 80% speed, pitch linked to speed and 50% reverb. Use it to prepare a moody soundtrack or a short music segment for a video project.

    Fine-tune speed and pitch, then adjust reverb amount, decay and tone so speech or a melody stays clear. The exported WAV, MP3 or AAC file can be imported into your video editor. This page processes audio; it does not edit video or publish to TikTok.

    How to use this effect

    1. Choose a recording or try the demo.
    2. Adjust the settings. The effect updates automatically; compare the result with the original.
    3. Choose an output format and download your audio.

    The preset is a starting point for edits. Adjust speed, decay and tone to keep the words clear. Your export is a regular audio file for your video editor.

    Privacy and sound quality

    Your recording stays on your device. Effects run locally in WebAssembly. Effects regenerate automatically after settings change. The preview and download share the same processed audio. The soft limiter protects against digital clipping.

    Time stretching can introduce artifacts, especially at extreme settings. Processing long recordings needs more memory; start with a short clip on mobile. Reverb adds a tail to the output.
