Frequently asked questions
What are the best settings for slowed + reverb?
Most slowed + reverb edits sit between 80% and 90% speed with a reverb amount around 30–40%. Lower the speed for a heavier, sleepier mood, and lengthen the reverb for a bigger, more distant sound.
Does slowing the song also lower the pitch?
Yes. Like a turntable running slow, the pitch drops together with the tempo. That deeper tone is a big part of the classic slowed + reverb sound.
Can I make the reverb longer without slowing the song more?
Yes. Speed, reverb amount, and reverb length are independent, so you can keep the tempo and only change the size of the space.
Is this tool free?
Yes. It is completely free, with no account, no watermark, and no limit on how many files you process.
Are my files uploaded anywhere?
No. Your audio is processed entirely in your browser and never leaves your device.
Which file formats are supported?
You can open MP3, WAV, FLAC, M4A, AAC, and OGG files, and download the result as MP3 (320 kbps), WAV, or FLAC.
