To make a lo-fi remix, open a track you already own in the Slowed + Reverb tool, pull the speed down slightly, add a touch of reverb, then warm it up by rolling off the highs in the Equalizer. Both tools run entirely in your browser with a live preview, so your audio never leaves your device. No account, no upload, no server — you drop a file in and export when it sounds right.
That two-step order is how I'd work: shape the space first, then shape the tone.
Lo-fi music leans on three things: a slight slow-down, a warm top end with the highs rolled off, and a small amount of gentle space. It's a chill, slightly dreamy feel rather than a dramatic one.
That's the key difference from a full slowed-and-reverb edit. When you make slowed and reverb songs, you slow the track hard and drench it in reverb — a big, sinking, underwater effect. A lo-fi remix is more restrained: you nudge the speed down just enough to relax the groove, keep the reverb subtle, and let the warm EQ do most of the mood work. If you push the speed the other direction instead, you're heading toward a nightcore song — the opposite feel.
Worth saying plainly: neither tool has a dedicated vinyl-crackle or tape-wobble generator. The "vinyl feel" people describe comes mostly from softening the high end (the EQ step below) plus the slight detune from slowing down. You'll get a warm, rounded, slightly-off character — not synthetic record crackle layered on top.

It sounds muddy or boxy. You've likely over-boosted the low-mids. Ease the 240 Hz bump back toward +1 dB, and don't stack it with a big 80 Hz boost. Our guide on why your mix sounds muddy walks through the usual culprits. If instead you want a fuller low end without mud, see boosting bass cleanly.
It sounds washed out or distant. Too much reverb. Go back to Step 1 and lower the Reverb mix toward 15–20%, or shorten the Reverb length. Lo-fi wants a hint of space, not a cathedral.
The pitch dropped too far / it sounds gloomy. The Speed slider is pulled down too low. Nudge it above your starting band — around 92–96% keeps the relaxed feel without the track sagging into a deep slow.
The highs still sound harsh. Pull the 6 kHz band down a couple more dB before touching 12 kHz — a lot of "brightness" lives around 6 kHz.
Do I need to upload my song anywhere? No. Both the Slowed + Reverb tool and the Equalizer run entirely in your browser, so your audio never leaves your device. There's no account, no upload, and no server processing your file. You drop in a track you already have — MP3, WAV, FLAC, or M4A — and everything, including the live preview and the export, happens locally on your own machine.
How slow should I set the speed for a lo-fi remix? Only slightly slow. Aim for roughly 88–92% on the Speed slider rather than the deeper drops used for full slowed-and-reverb edits. Because lowering speed also lowers pitch, even a small reduction adds that relaxed, gently detuned feel. If the track starts sounding gloomy or sagging, raise the slider back toward 100% until it settles into a comfortable groove.
Can these tools add real vinyl crackle or tape wobble? Not as a dedicated effect — there's no crackle or wobble control. The vinyl-like warmth comes from two real things you can do: rolling off the highs in the Equalizer to soften the top end, and the subtle detune that slowing the track introduces. Together they give a rounded, warm, slightly-imperfect character, but they won't layer synthetic record noise over your track.
Why export a WAV between the two steps? WAV is lossless, so it carries the full quality of your slowed version into the Equalizer without adding compression. If you exported MP3 after Step 1 and MP3 again after Step 2, you'd stack lossy compression twice and lose a little clarity each time. Keep WAV in the middle, then choose MP3 or Opus only for your final shareable file.
My remix sounds muddy — how do I fix it? Muddiness usually means the low-mids are too strong. Reduce any boost around 240 Hz back toward +1 to +2 dB, and avoid pairing it with a large 80 Hz boost. A gentle roll-off of the highs is what gives lo-fi its warmth — you don't need heavy low-mid boosting to get there. The Flatten button lets you reset and rebuild the EQ curve if it gets away from you.
