TikTok audio effects for your next song edit

Choose an effect by the change you want to hear: playback speed, pitch, space, bass weight or stereo movement.

These are suggested starting points, not fixed preset specifications. Adjust them against your source recording.

Start with one effect. Adding heavy reverb, extra bass and stereo rotation together can hide the vocal and soften the kick.

Make an edit in three steps: load audio, adjust a looping selection, then render the version you want.

1. Drop your audio file or tap "Try a demo track". Playback starts so you can hear the source before changing it. Choose a file within the 10-minute and 100 MB limits.
2. Pick a preset and shape the clip. Drag across the waveform or use the 15 s, 30 s or 60 s buttons. The selection loops while you adjust sliders. Use the Effect/Original switch to compare against the source.
3. Download the clip or full track. Choose MP3 or WAV, then render your selection. Check that you selected the clip rather than the whole file if you only need one hook.

Keep the first pass simple. Find the musical moment before spending time adjusting room size or rotation speed.

Use modest settings first: 90% speed, 10% reverb mix or +3 dB of bass is enough to judge the direction.

Speed and pitch are different jobs. Speed changes move both tempo and pitch together. The pitch slider changes semitones while keeping tempo fixed.

If a slowed vocal becomes hard to understand, move speed closer to 100% before adding more effects. If bass boost makes the kick crackle, reduce the boost. More level is not the same as more punch.

Slowed edits suit lingering shots, while sped-up edits suit quick movement and tighter cuts.

For late-night footage, start around 85-90% speed and keep reverb below the point where words smear together. For dance or workout clips, try 110-115% and check whether the main movement still lands on the beat. Nightcore pushes the vocal higher, which can suit animated action but can also make an already bright voice sharp.

Use 8D for headphone-focused listening clips. Its stereo movement is less obvious through a single phone speaker. Bass boost fits car and gym footage, but audition it on a phone too.

Place your video cut on a clear kick, snare or lyric entrance. Listen to the exported file before placing it in your video editor. An effect cannot guarantee reach or prevent a weak cut.

Your audio stays on your device: the browser processes it locally and never uploads the file.

The tools are free and need no account. On a phone, use the file picker to select audio stored on the device. A smaller source file is a sensible choice when memory is tight. Keep the browser tab open while rendering your download.

Input compatibility depends on what your browser can decode. MP3 and WAV are practical formats to try; if a file will not open, check its format and the 10-minute and 100 MB limits. Download options are MP3 and WAV.

A failed import is not a reason to keep changing effects. Get the source playing correctly first, then start editing.

Changing speed, pitch or reverb does not change who owns a song, and platforms may mute or claim edits of other people's recordings.

For an original, make a track with SoundUser using the TikTok music generator, then bring that audio into the effects tool.

Here is a full generation prompt for an original you could edit: Instrumental electronic pop at 120 BPM in A minor, dry kick, tight clap, rounded synth bass and a short plucked synth hook. Keep the melody clear and leave space between phrases. No vocals.

The intended result is a steady beat with a recognizable hook that remains readable when sped up. If the generated arrangement is too busy, replace the instrument description with kick, clap, bass and one repeating plucked melody. If the later edit sounds muddy, reduce reverb before changing the source prompt. This is an intended workflow, not a claim about a rendered result.
