Choose a recording you have permission to use, identify a musical passage, then trim or chop it in an audio editor or sampler. Arrange the pieces to your project's pulse, listen for clicks and clashes, and check the rights for your intended release.
To sample a song, select a passage from a recording you have permission to use, cut it into a loop or smaller pieces, and arrange those pieces in a new project. Match the timing to your beat, listen for clicks and conflicting notes, and keep a record of the source and its license.
A sample is audio taken from a recording. A loop repeats a passage; a chop is a smaller piece you can place or trigger in a new order. You can start with a recording you made, a licensed sample, or an authorized song recording. Sampling an existing commercial song for release can involve rights in both the recording and the underlying composition; changing or isolating the sound does not automatically grant permission.
1. Choose a source and a musical moment
- Start with a permitted file. Keep the original, source URL or creator information, license and any correspondence. Check whether the permission covers your planned release, platform, attribution and commercial use.
- Listen for a usable phrase. A piano chord, drum break, vocal word or two-bar instrumental passage can each become a different kind of sample. Choose a relatively exposed sound if you need it to stand alone.
- Mark the boundaries. Identify the first intended beat or note and the end of its phrase. Leave a little room for an attack or decay, and note the source timestamps so you can return to them.
If you have the original multitrack project or an authorized isolated track, start there. A finished stereo mix combines instruments, effects and vocals; cutting a passage does not remove the other sounds occurring at the same time.
2. Trim the passage and listen to its edges
In a digital audio workstation (DAW), import the permitted recording onto an audio track, zoom in, select the phrase and make a copy or split it at its boundaries. Play just the selection, then repeat it: a cut that sounds fine once can click or feel late when looped. Move the cut or try a short fade, while making sure you do not soften a drum attack or cut off a note's tail.
For one short excerpt, the free audio trimmer accepts supported mono or stereo MP3 or WAV files up to five minutes and 50 MiB. Set the start and end, prepare a WAV and preview the actual download. Its optional 5 ms edge fade can soften a click, but may affect a transient at the boundary; move the cut earlier or disable it if needed. The tool makes one continuous excerpt at a time, not a batch of slices. WAV output is 48 kHz, 16-bit PCM, and output size is capped at 50 MiB.
3. Loop it or make chops
For a loop, place the whole phrase on the timeline and repeat it. The start and end need to form a musically useful cycle; a note's reverb can spill over the boundary, so listen to several repetitions rather than only the first pass.
For chops, split a copy at meaningful points such as drum attacks, chord changes or the start of a word. Place the pieces on your DAW timeline or load them into a sampler that maps slices to notes or pads. Ableton's Simpler documentation describes slice playback and warp behavior; controls vary with software and version.
A four-chop starting exercise
Imagine a one-bar phrase in 4/4 with four distinct chord attacks on beats 1, 2, 3 and 4. Make a working copy, cut just before each attack, and name the pieces A, B, C and D. Place A, C, B and D on beats 1–4 of a new bar. This is an exercise, not a rule: adjust the cut points and lengths by ear. If a chord sustains over the next attack, its tail may be interrupted; allow overlap or choose a different cut rather than assuming every beat is an independent sound.
| Problem | What to try |
|---|---|
| Click at a cut | Zoom in, move the boundary or try a short fade; check that the attack remains intact. |
| Loop drifts against drums | Check the actual start, bar length and source tempo. A live performance can vary in tempo. |
| A note or reverb is cut short | Extend or overlap the slice, or use a less crowded passage. |
| The sample clashes with the bass | Check the notes and harmony by ear; change the bass, the sample pitch, or the selected passage. |
4. Match the beat and pitch
Set a project tempo that suits the source, then align the first meaningful beat with the grid. The tap tempo tool can give you a starting estimate; tap several bars and check the actual loop against a metronome. If the sample is 100 BPM and the project is 100 BPM, one 4/4 bar lasts 2.4 seconds. A different tempo or a phrase that is not exactly one bar changes that length.
Use your DAW's time stretching or warping if the loop needs to fit a different tempo, then listen for transient smearing and artifacts. Some samplers change speed and pitch together when transposed unless a suitable stretch mode is enabled. If the musical key matters, the song key finder offers candidate keys for supported short audio; verify by ear because a short or ambiguous sample may not identify its parent song's key.
5. Add new parts and export a test
Build a simple drum pattern or bass line around the sample. Leave space for its strongest rhythm and compare the sample alone and in the mix. Check whether overlapping low frequencies make the kick or bass hard to hear. Save an editable project and export a short test; listen to the rendered file for the loop seam, levels, beginning and ending. For software-specific cutting and arrangement, see how to sample in FL Studio; for a concrete drum pattern, follow the FL Studio beat tutorial.
Can you isolate one instrument before sampling?
If the only available source is a finished mix, a separator can estimate an instrument or voice to audition as a working source. In Saturalabs, upload a supported file up to 50 MB, describe the audible target and compare Isolated sound with the original. It may retain bleed or omit wanted notes; it does not recover the original track. AI downloads require an account and sufficient credits, with cost shown before download. The instrument isolation guide explains how to compare the result. Isolation does not change the rights in the underlying material.
Do you need permission to sample a song?
Plan rights before releasing or distributing the new recording. In the United States, the U.S. Copyright Office distinguishes the sound recording from the musical composition; using an existing recording can implicate both. Its sampling guide explains these separate interests and licensing. A license for one use does not necessarily cover every platform or territory. There is no universal number of seconds that automatically makes a sample safe to release; rules and exceptions depend on the facts and jurisdiction. When uncertain, get qualified advice or use material with a license that covers your use.
Common questions
Is sampling the same as interpolation?
Sampling uses audio from an existing recording. Interpolation generally involves making a new recording of a musical element; it can still involve rights in the underlying composition. Check permissions for the specific use.
Can I sample from an MP3?
Yes, if your software can decode the file and you have the necessary permission. An MP3 is lossy; converting it to WAV for editing will not restore information removed during encoding. Keep the source and avoid repeated lossy exports.
Do I need a sampler plugin?
No. You can cut and arrange audio clips directly on a DAW timeline. A sampler is useful when you want to trigger or play slices from MIDI notes or pads.
