Frequently asked questions

How do I make a slowed + reverb version of a song?

Upload your song, select the Slowed + Reverb preset (or manually set speed to 0.8x, add reverb, boost bass), preview it, and download. The entire process runs in your browser. No server upload, no account.

How do I make a nightcore version of a song?

Upload your song and select the Nightcore preset. This speeds the track up to around 1.25x and shifts the pitch higher. You can fine-tune the speed and pitch to get the exact sound you want.

What is the difference between slowed + reverb and vaporwave?

Slowed + reverb typically reduces speed to 0.8x with heavy reverb. Vaporwave goes slower (0.6-0.7x) with more reverb and sometimes a lo-fi or chopped effect. Both create a dreamy, atmospheric sound from the original.

Can I adjust the speed and reverb separately?

Yes. Use the sliders to set speed (0.5x to 1.5x), reverb amount (dry to wet), and bass boost independently. The presets give you a starting point, then you can fine-tune.

Does this upload my song to a server?

No. Speed change uses the Web Audio API's playbackRate, and reverb is rendered locally through a convolution buffer. Your audio stays in browser memory and is never transmitted anywhere.

Can I use this on my phone?

Yes. The tool works in any modern mobile browser. Upload your file, pick a preset, and download the result directly to your phone.

What format is the output?

Lossless WAV at the original sample rate. WAV preserves full quality with no compression artifacts. You can convert to MP3 afterward if you need a smaller file.

Does the pitch actually change when I slow the song down?

Yes. This tool links speed and pitch like a turntable, so slowing to 0.8x lowers pitch by about 3.8 semitones and a nightcore 1.25x raises it by about 3.7 semitones. That linked pitch shift is what gives slowed + reverb its characteristic sound.

Can I use the output on TikTok or YouTube?

The tool creates the audio file. How you use it is up to you. Many people upload slowed + reverb or nightcore versions to TikTok, YouTube, and SoundCloud. Make sure you have the rights to the original song.

How do I make a slowed + reverb version of any song for TikTok?

Upload your song, select the Slowed + Reverb preset, and download the WAV. The preset slows the track to 0.8x with reverb and bass boost. Import it into your TikTok video editor or CapCut. The whole process takes under a minute.

How do I make a nightcore version of a song without software?

Upload the song here and click the Nightcore preset. It speeds the track to 1.25x with a higher pitch. Fine-tune the speed if you want it faster or slower. Download and use anywhere. No software to install, no account to create.
