Free online song remixer — slowed + reverb, nightcore, 8D and lo-fi
The Ajenza Song Remixer turns any track into a remix right in your browser. Upload a song and pick a preset — Slowed + Reverb, Nightcore, 8D Audio, Lo-Fi or Club — or fine-tune the speed, reverb, bass boost, echo and stereo rotation by hand, then download the result as a WAV. Everything is processed locally with the Web Audio API, so your music is never uploaded to a server.
Is my song uploaded to a server?
No. Your track is decoded and processed entirely in your browser — the audio never leaves your device.
How do I make a slowed + reverb remix?
Upload your song, choose the Slowed + Reverb preset (or lower the speed and raise the reverb yourself), preview it, then download the WAV.
Can I make a nightcore or 8D audio version?
Yes — there are one-tap Nightcore, 8D Audio, Lo-Fi and Club presets, plus manual controls for everything.
What formats can I use?
Upload MP3, WAV, M4A or OGG; the finished remix downloads as a WAV.
