Lofi Maker

Make a song lofi in your browser: slow it a touch, darken the tone, add moderate reverb and some bass. Honest about what it cannot add, settings and MP3 export.

Open the free editor: upload MP3, WAV, AAC, OGG or FLAC, adjust speed, reverb, bass, tone, width and space, then export MP3 or a ZIP of many tracks. Everything runs in your browser.

A lofi maker, in the sense people usually mean, turns a clean modern recording into something that sounds older, softer and further away. The editor above gets you a good part of the way there with four moves: slow the track slightly, roll off the top end, add a moderate reverb, and put a little weight in the low end. This page gives you the recipe, the settings, and a straight answer about what the tool cannot do, because lofi as a genre uses several tricks this editor does not have.

The same controls power the slowed reverb maker, and the two styles overlap. The difference is degree. Slowed + reverb pushes speed and reverb hard; lofi is gentler on both and leans more on tone. The Tone and Reverb pages explain those two controls in detail.

What lofi means as a sound

Lofi, short for low fidelity, started as a description of recordings made on cheap or worn equipment and became a style of its own: hip hop beats and chill instrumentals with a dusty, muffled, slightly unsteady character. Listeners associate it with a specific set of textures:

• A rolled-off, soft top end, as if heard through a wall or an old speaker
• A gentle, slightly slow tempo, often in the 70 to 90 BPM range
• Warm, rounded low end
• Room or tape ambience that fills the gaps
• Surface noise, vinyl crackle, tape hiss
• Pitch wobble and flutter from worn tape or a drifting turntable
• Chopped, looped samples with abrupt edits

The editor can produce the first four. It cannot produce the last three. That is the honest frame for everything below.

The lofi recipe with these controls

Slow a touch

Lofi does not want the deep slowed drop. Set Speed between 0.90x and 0.96x with Preserve pitch off. That is roughly 1 to 2 semitones down, enough to make the track feel relaxed and slightly heavier without turning the singer into someone else. If the source is already slow, 0.95x may be all it needs. If it is an upbeat pop song at 120 BPM, 0.90x brings it to 108 BPM, which starts to feel like a lofi tempo.

Dark Tone

Tone is the control doing most of the work. It is a high shelf from -10 to +10 dB, and lofi wants it well into the negative. Start at -6 dB. That takes the sheen off cymbals and vocal sibilance and gives the heard-through-a-wall quality. Go to -8 dB for a heavier muffle. The Haze Chamber preset sits at -10 dB, which is darker than most lofi needs, but try it to hear the extreme.

Moderate Reverb

Lofi uses reverb for ambience, not for drama. Set Reverb to 25 to 40% and Space to 2.0 to 3.0 seconds. Short decay with moderate mix reads as a room rather than a cathedral. If the track feels dry and clinical, raise Reverb first. If it feels cloudy, shorten Space.

Some Bass

Lofi low end is warm and round, not booming. +3 to +5 dB on the Bass shelf is usually enough. Pair it with the dark Tone and the balance tilts toward the low mids, which is where the warmth lives. Avoid stacking +10 dB Bass with -10 dB Tone unless you are going for heavy slowed rather than lofi.

Width

Keep Width near 1.0. Old recordings tend to be narrow rather than wide, and a slightly reduced width of 0.8 to 0.9 can suggest age. Width at 0 is mono, which is a legitimate lofi choice for some material.

Settings table

The Wave Drift preset, at 0.90x, 50% reverb, 2.8 s, +2 bass, -1 tone, is a reasonable starting point if you lower its Reverb to around 35% and pull Tone down to -5 dB. See the Wave Drift preset page for its exact character.

Step by step

1. Add the file. MP3, WAV, AAC, OGG or FLAC, decoded in your browser.
2. Start from Dry so you are not inheriting a heavy slowed setting.
3. Set Speed to 0.92x. Listen to whether the groove still moves.
4. Pull Tone to -6 dB. This is the moment it starts sounding lofi.
5. Set Reverb to 30% and Space to 2.6 s.
6. Raise Bass to +4 dB.
7. Nudge Width down to 0.9 if the source is very wide.
8. Compare with Dry while playing. Then Create preset and name it, so the next track gets the same treatment.
9. Download. MP3 at 96 kbps and 32 kHz.

What this lofi maker cannot add

Being clear about this saves you a frustrating half hour.

No vinyl crackle or tape hiss. There is no noise layer in the editor. If you want surface noise, add it afterwards in a video editor or DAW by layering a crackle recording under the exported MP3.

No tape wobble or pitch flutter. Speed is fixed for the whole file. There is no modulation, so the slight drift you hear in lofi records cannot be reproduced here.

No chops, stutters or loops. The editor processes the file as one continuous piece. It cannot cut a sample, repeat a bar or skip beats. The chopped and screwed maker page explains what the tool can and cannot do for that related style.

No bit reduction or saturation. The muffle comes from the Tone shelf, which is a clean filter. There is no distortion, no sample rate crunching, no tape emulation.

No sidechain pumping or beat-synced effects. Nothing in the chain follows the tempo.

No trimming. Cut intros and outros elsewhere.

MP3 at 96 kbps only. Some people like that a lower bitrate adds a touch of grain to a lofi edit, and at 96 kbps you may hear a little. It is not a deliberate lofi effect, just the encoder. It is fine for YouTube, TikTok and streams that re-encode. For a release, finish in a DAW from a WAV source.

In short, this editor makes a song sound lofi in tone, tempo and space. It does not make it sound like a sampled, chopped, tape-recorded lofi beat. If your target is the full genre, use this as the first pass and add texture in a DAW.

Making a lofi playlist in one pass

Add every track you want to treat, Select All Tracks, apply your saved lofi preset, and Download All. The ZIP contains one MP3 per track with the same treatment, which is exactly what a consistent lofi playlist needs. Tracks that need a different speed can be selected on their own and adjusted. The settings by genre guide has further starting points for different source material.
