Best Chopped and Screwed Settings
Every preset shows its speed ratio and the semitone drop that comes with it, because the two are the same fact stated twice.
| Preset | Settings | When to Use |
|---|---|---|
| Classic Screw | 0.75x · −5.0 st · skip back every 8 | The reference setting. A 90 BPM source lands near 68 BPM, inside the documented screwed window. |
| Slow & Chopped | 0.75x · −5.0 st · stutter every 4 | Same slowdown, twice the chop density. Good for hooks and short edits. |
| Heavy Stutter | 0.80x · −3.9 st · stutter every 2 | A chop on every other beat. Obviously a remix rather than a tape. |
| Screwed Only | 0.75x · −5.0 st · no chops | Slowed and pitched down with no chopping — screwed but not chopped. |
| Triplet Bounce | 0.85x · −2.8 st · triplet every 4 | Lighter slowdown with a three-against-four repeat that pushes the groove. |
Speed and pitch move together here, which is the point — screwing came from slowing physical media, and that always drags pitch down with tempo. If you want the tempo down but the key intact, that is a different effect and the speed changer or the slowed reverb generator is the better tool.
Why Use This Chopped and Screwed Maker?
It actually chops
Most tools that rank for this term only slow the song down. This one cuts, repeats, and skips beats — the chopping half of the name.
Chops land on the beat
The tempo is estimated from the audio itself, so repeats fall in time instead of wherever the clock happens to be.
Screw to a target BPM
The classic screwed target is an absolute 60–70 BPM, so the correct speed ratio depends on the source. Pick the target, not the percentage.
Insert or replace
Insert keeps every bit of the original and lengthens the track. Replace overwrites the beat and preserves the runtime. Both are real approaches.
No account, no export cap
No signup, no watermark, and no daily export limit — full-length MP3 or WAV every time.

Chopped and Screwed Is Two Things, Not One
The name is a pair of verbs, and almost every online tool only does the second one. Screwed means slowed: the record plays back at a lower speed, and because the medium itself is running slow, the pitch falls with it. Reference sources put the target around 60 to 70 beats per minute, which for most source material is a ratio somewhere near 0.75x and a key drop of roughly five semitones.
Chopped is an edit, not a filter. It means taking a phrase apart and putting the pieces back in a different order — repeating a line, stuttering a word, skipping a beat so the track lurches forward. Slowing a song down does none of that. If you have used a "chopped and screwed" converter and the output was simply a slower version of the input, this is what was missing.
How DJ Screw Actually Did It
Robert Earl Davis Jr. — DJ Screw — was born in Smithville, Texas in 1971 and started DJing at twelve. He began making his slowed mixes around 1990, and by late 1991 they had become his main focus. The output was enormous: over 350 screwtapes, sold from Screwed Up Records and Tapes on Cullen Boulevard in Houston, with the Screwed Up Click — Lil KeKe, Big Hawk, Big Moe, E.S.G., Fat Pat — rapping over them. He died in Houston in November 2000, aged 29.
The method was physical and worth understanding, because it explains the sound. Two copies of the same record spun at once, one running slightly behind the other, and he cut between them with the crossfader at the moments he wanted to bring out. His fader was set hamster-style — reversed from the standard orientation — so he could make faster stabs between the discs, and some recordings ran four turntables. The slowdown came from the turntable pitch control and from running the recording back through a four-track tape deck at reduced speed, taking it down another generation. Nothing about that process preserves pitch, which is precisely why screwed vocals sit so far below the original.
One piece of the story is genuinely contested and we would rather say so than pick a side: the origin of the name. One account credits a friend reacting to Davis defacing records he disliked with a screw; another names a different friend and a screwdriver, a year earlier. Both circulate widely. The mechanism people often repeat — that he slowed the disc by hand and let it speed back up — is uncited even where it is most often quoted, so treat it as folklore rather than technique.
Chopped and Screwed vs. Slowed and Reverb
Slowed and reverb descends directly from chopped and screwed, by way of vaporwave, and the differences are real rather than cosmetic. Chopped and screwed is varispeed — pitch falls with tempo — plus arrangement editing, and it came out of a specific place and scene in Houston in the early 1990s. Slowed and reverb usually keeps the pitch closer to the original, adds a large reverb, and does not chop at all. When slowed and reverb went mainstream around 2020 there was a documented backlash over attribution, with critics calling it a gentrified version of Screw's work; that argument is worth knowing about whichever side of it you land on. If the modern sound is what you are after, use the slowed reverb generator — it answers the comparison and the copyright questions in more depth there.

Chopped and Screwed FAQ
What is the difference between chopping and screwing?
They are two separate operations that usually travel together. Screwing is slowing the record down, which drags the pitch down with it and produces the heavy, syrupy sound. Chopping is editing the arrangement: cutting between two copies of the same record to repeat a phrase, stutter a word, or skip a beat. A track can be screwed without being chopped — plenty are — but a tool that only slows a song down has done half the job and should not really be called a chopped and screwed maker.
What BPM should a chopped and screwed song be?
The commonly cited target is 60 to 70 beats per minute. That is an absolute figure, not a percentage, which is why the correct speed ratio depends on what you started with: a 90 BPM source needs roughly 0.67x–0.78x to land in the window, while an 80 BPM source only needs 0.75x–0.88x. This tool detects the source tempo and works the ratio out for you when you pick a target.
Does the pitch drop when you screw a song?
Yes, and it is supposed to. Screwing came from physically slowing turntables and tape, and slowing a physical medium lowers pitch and tempo together — the effect people mean by varispeed. That is why screwed vocals sit so much lower rather than just sounding slower. Modern slowed and reverb tools often preserve pitch instead, which is a different sound with a different lineage.
How many semitones does chopped and screwed drop the pitch?
It follows directly from the speed ratio: 12 × log₂(ratio). At 0.85x the drop is about 2.8 semitones, at 0.80x about 3.9, at 0.75x about 5.0, and at 0.70x about 6.2. The speed control on this page shows the semitone figure live as you move it, so you can aim for a key drop rather than guessing at a percentage.
Does chopping make the song longer?
That depends which mode you use, and both exist in practice. Insert mode plays the repeats and then plays the beat, so nothing from the original is lost and the track gets longer — this is what copy-pasting a slice in a DAW does. Replace mode overwrites the beat with the repeats, keeping the original runtime, which is closer to a DJ cutting to a second deck and coming back to find the first has moved on. Insert is the default here because it never discards audio.
Should I chop before or after slowing the song down?
For the result, it does not matter much: slowing is a uniform time stretch, so chopping first and then slowing gives the same arrangement as the reverse, just scaled. It matters for the grid. This tool chops in the original timeline, which means the chop positions stay locked to the source tempo and the detected BPM stays meaningful no matter where you set the speed. Historically the question barely arose, because a DJ slowed the decks and chopped in the same live pass.
How often should you chop in a chopped and screwed remix?
There is no correct interval, and anyone quoting one is inventing it. The technique was played by ear — the chops went where the DJ wanted to pull something out, usually a vocal line worth hearing twice. As a practical starting point, a chop every 8 beats reads as a tape-style remix, every 4 makes it a clear feature of the arrangement, and every 2 turns it into an effect. Set the interval, listen, and move it.
How did DJ Screw actually chop records?
With two copies of the same record. He kept both spinning, one running slightly behind the other, and cut between them with the crossfader at the moments he wanted to bring out — which is what produces the stutters and repeated lines. His fader was set up hamster-style, reversed from the usual orientation, so he could make faster stabs between the two discs, and some recordings used four turntables. The slowdown came from the turntable pitch control and from running the tape back through a four-track at reduced speed.
Can you chop and screw a song without a DAW?
Yes — that is what this page is for. The usual advice is to slow the track in one tool and then go and chop it manually in Serato, Audacity, or a DAW, because most online tools cannot chop at all. Here the chopping is built in and beat-locked, so you can screw and chop in one pass in the browser, with no software to install and no account.
Why does my chopped remix sound off-beat?
Almost always because the detected tempo is slightly off, or right but on the wrong beat. Tempo detection is an estimate: it can land on half or double the real figure, and it struggles with rubato, live drumming, and long intros. Nudge the source BPM up or down by one and listen to whether the chops tighten or drift. If the tempo is right but the chops fall in odd places, the track's first downbeat is probably not where the file starts.
