FROM SONG TO YOUR SONG

Your next replay, in four steps.

Slowed + reverb lowers a song’s speed and pitch, then adds a soft room-like echo. A familiar track feels more spacious. Prefer more energy? Try the sped-up or nightcore preset instead.

A few things you might wonder.

How do I make a slowed and reverb song?
Choose an audio file or preview the Echo demo. The Slowed + reverb preset starts at 0.85× speed with 35% reverb. Press play, adjust the controls to taste, then download your own audio as MP3 or WAV. The bundled Echo demo is for preview only.
Is this slowed and reverb generator free?
Yes. Previewing and downloading are free, with no signup or watermark. You do not need Echo Equalizer to use this tool.
Does my song get uploaded?
No. Your file is decoded, played and exported in your browser. Audio and filenames are not sent to Hapibits. The website uses standard usage analytics, but these do not include your audio or filename. Reloading the page clears your selection.
Can I make sped-up and nightcore songs too?
Yes. Choose Sped up for 1.20× speed or Nightcore for 1.35× speed, then adjust the speed between 0.60× and 1.50×. Pitch follows speed: slowing a song lowers its pitch, and speeding it up raises its pitch. This tool does not preserve the original pitch.
Which audio files can I use?
Use a mono or stereo audio file up to 5 minutes and 50 MB. MP3 and WAV work in most modern browsers; M4A, AAC, OGG and FLAC support depends on your browser. Downloads are 192 kbps MP3 or 16-bit WAV at 44.1 kHz. Export may take longer on a phone.
Why is my download longer or quieter?
Slowing down increases the duration. Reverb also adds a 2.4-second tail so the ending can fade naturally. The mix reserves headroom for bass and effects and reduces peaks if necessary to avoid sample clipping. Preview volume only changes listening volume, not your downloaded file.
Can I use this on my phone?
Yes, in a current version of Safari, Chrome, Firefox or Edge that supports Web Audio. Choose a file from your phone, preview your mix, and save the download. Shorter songs use less memory. Keep the tab open while exporting.
