The Art of Sampling

Sampling turns existing recordings into new music. It built hip-hop, jungle and much of modern pop. This lesson covers where samples come from, how to chop and stretch them, how to "flip" a sample into something new, and the legal basics you need to know before you release.

What is Sampling?

Sampling means taking a piece of an existing recording and reusing it in a new track. A sample can be anything: a single drum hit, a two-bar drum break, a vocal phrase, a chord from a record, or a field recording of rain.

Producers use samples in two main ways:

The tool that plays samples is a sampler. It maps audio to keys or pads so you can trigger it with MIDI, change its pitch, and shape it with envelopes and filters.

A Short History

Breakbeats and hip-hop

In the Bronx in the early 1970s, DJ Kool Herc noticed that dancers went wildest during the break: the part of a funk or soul record where everything drops out except the drums. He used two copies of the same record on two turntables to switch between them and extend the break. That technique is the root of hip-hop.

A few breaks became the most sampled recordings in history:

Samplers and the MPC

Digital samplers made this possible in the studio. The E-mu SP-1200 (1987) had only about 10 seconds of 12-bit sample time, and its gritty sound shaped late-80s and 90s hip-hop. The Akai MPC60 (1988), designed with Roger Linn, combined a sampler with a sequencer and 16 pressure-sensitive pads. MPCs became the classic hip-hop production tool, and the pad grid they made famous is now on controllers everywhere.

In the early 2000s, producers such as Kanye West and Just Blaze popularized chipmunk soul: soul vocal samples sped up so they sound higher and faster.

Finding Samples

Crate digging is the old-school practice of searching through second-hand record shops for obscure records with usable breaks and loops. Many producers still do it, both in shops and online.

Producer tip

Organize your samples by type (kicks, snares, loops, vocals, FX) and add your favorites to a "best of" folder. You'll spend more time making music and less time scrolling.

Chopping

Chopping means cutting a sample into smaller pieces, then rearranging or replaying them. A chopped sample can sound completely different from the original.

  1. Find the part you like: a 1–4 bar phrase, a chord, a vocal word.
  2. Cut at the transients. A transient is the sharp start of a sound, like a drum hit or a plucked note. Cutting just before a transient gives clean chops.
  3. Trim to zero crossings. Cut where the waveform crosses the center line, or add a tiny fade of about 2–10 ms, to avoid clicks.
  4. Assign each chop to a pad or key in a sampler.
  5. Play a new pattern using the chops.

Slicing to MIDI

Most DAWs can do steps 2–4 for you. They detect the transients, cut the audio into slices, and map each slice to its own MIDI note:

Now you can rearrange a drum break just by moving MIDI notes. This is how jungle producers rebuilt the Amen break into endless variations.

Time-Stretching vs Repitching

A sample rarely matches your track's tempo. You have two ways to fix that:

MethodWhat happensSound
Repitching (resampling)Speeds up or slows down the audio, like a record on a faster or slower turntable. Pitch and tempo change together.Natural, no artifacts. Faster = higher; slower = lower.
Time-stretchingSoftware changes the tempo while keeping the pitch the same (or changes pitch without changing tempo).Fine for small changes. Big changes add warbles and smearing (artifacts).

The repitching math

Speed ratio = new BPM ÷ original BPM Semitones = 12 × log2(ratio) Example: 90 BPM loop → 100 BPM track ratio = 100 ÷ 90 = 1.11 pitch change ≈ +1.8 semitones Double speed (×2) = +12 semitones (one octave up) Half speed (×0.5) = −12 semitones (one octave down)

Repitching a loop up about 2 semitones is often unnoticeable. Repitching up 4–7 semitones gives the bright "chipmunk soul" sound.

Warping

Warping is time-stretching with markers. You place warp markers on the beats of a sample, and the software stretches the audio between them so every beat lands on your grid. This also fixes loops played by humans whose tempo drifts. Your DAW's stretch mode matters:

Note

Drum loops stretch best with a transient-based mode (Beats in Ableton, Slicing in Logic). Melodic or full-mix loops sound better in a polyphonic mode, or simply repitched.

Flipping a Sample

Flipping a sample means transforming it so much that it becomes a new idea, rather than just looping someone else's music. Ways to flip:

Filtering is one of the most common moves. Hip-hop producers often low-pass a sampled loop to hide its original drums, or high-pass it so the new bassline and kick have space. Try it on a sampled drum loop below.

Now hear how a sample-based beat sits together. This boom bap pattern is the kind of beat producers built on the MPC and SP-1200 from chopped drum hits.

The Legal Side

Not legal advice

This is a general overview. Copyright law differs between countries. Before releasing music with uncleared samples, talk to a music lawyer or a sample clearance service.

Every commercial recording usually has two copyrights:

Clearance means getting permission from the owners, usually for a fee, a share of royalties, or both. To sample a recording directly, you normally need to clear both the master and the composition.

Interpolation

Interpolation means re-recording part of a song (replaying the melody or singing the lyric) instead of sampling the original audio. Because you're not using the original recording, you usually only need to clear the composition, not the master. This is often easier and cheaper, which is why it's common in pop.

Lessons from famous cases

Safe options

"It's only 2 seconds" and "I changed the pitch" are not legal defenses on their own. Even short or heavily processed samples can infringe copyright.

Try it in your DAW
  1. Find a royalty-free drum break or melodic loop from your DAW's library or a sample pack, and drag it onto an audio track.
  2. Set your project to a different tempo (for example 92 BPM) and turn on warping or stretching [Ableton: Warp; FL Studio: stretch mode in the sample or audio clip; Logic: Flex Time]. Try a drum mode, then a repitch mode, and compare.
  3. Slice the loop to MIDI [Ableton: Slice to New MIDI Track; FL Studio: Slicex; Logic: Quick Sampler → Slice].
  4. Rearrange the slices into a new 2-bar pattern. Repeat at least one slice and leave at least one gap.
  5. Repitch one slice up 5 semitones and reverse another.
  6. Add a low-pass filter around 2–3 kHz and your own kick underneath. You've flipped your first sample.

The famous drum solo from "Amen, Brother" by The Winstons is called the Amen .

Speeding up a sample to double speed raises the pitch by semitones.

Re-recording part of a song instead of sampling the original audio is called .

1. What is the main difference between repitching and time-stretching?

  1. Repitching only works on drums
  2. Repitching changes pitch and tempo together; time-stretching can change tempo while keeping pitch
  3. Time-stretching always sounds better
  4. There is no difference

Repitching works like changing a turntable's speed. Time-stretching uses software to separate tempo from pitch, at the cost of artifacts on big changes.

2. Where should you usually cut when chopping a drum break?

  1. In the middle of each hit
  2. Exactly every 100 ms
  3. At the loudest point of the waveform
  4. Just before each transient

Cutting just before the sharp start of each hit keeps the attack intact and gives clean chops.

3. To release a track that directly samples a commercial record, what do you normally need to clear?

  1. Nothing, if the sample is short
  2. Only the composition
  3. Both the master recording and the composition
  4. Only the artwork

Direct samples use the recording (master) and the underlying song (composition), so both usually need permission.

4. Which sampler/sequencer, designed with Roger Linn, became a classic hip-hop tool?

  1. Akai MPC60
  2. Roland TB-303
  3. Minimoog
  4. Yamaha DX7

The MPC60 (1988) combined sampling, sequencing and pads, and the MPC line became central to hip-hop production.

5. A 90 BPM loop is repitched to fit a 180 BPM track. What happens to its pitch?

  1. It stays the same
  2. It drops one octave
  3. It rises about 2 semitones
  4. It rises one octave

Doubling the speed doubles every frequency, which is +12 semitones (one octave).
