Every producer has a folder of voice memos, studio takes and old project bounces with great moments buried inside them: a vocal ad-lib, a log drum, a guitar lick, a two-bar groove. This free sample maker helps you pull those moments out. Load a recording, chop it on the waveform, clean each piece up and download it as a WAV named with its tempo and key, or grab the whole set as a ZIP sample pack. It all happens in your browser, so your unreleased audio is never uploaded.
How it works
- Choose a recording from your phone or computer (a vocal take, a drum loop, a keys idea) or try the demo loop. It is opened in your browser and never uploaded.
- Mark chops: drag across the waveform, tap "Chop at playhead" in time while it plays, or press Auto-slice and set the sensitivity so each drum hit or syllable becomes its own chop.
- Tap a chop to edit it: trim the edges (they snap to zero crossings so there are no clicks), add fades, normalise, reverse or shift the pitch, and loop it to hear how it sits. Set the loop to 1, 2, 4 or 8 bars to lock it to the tempo.
- Tempo and key are detected for the whole file, or for one chop, using the same analysis as Beat Lab. They go into each file name, like mypack_vox_01_112bpm_Fmin.wav.
- Download one WAV or the whole pack as a ZIP, in 16-bit or 24-bit at 44.1 or 48 kHz, ready for FL Studio, Ableton, Logic, GarageBand or an MPC.
Frequently asked questions
What is a sample maker?
It is a tool that turns a longer recording into short, reusable pieces of audio called samples: a drum hit, a log drum, a vocal chop, a guitar stab or a two-bar loop. Producers load those pieces into a beat-making app or drum pad and play them in new patterns. This one cuts, cleans and names the pieces for you and exports them as WAV files or a ZIP pack.
How does auto-slice find the hits?
It looks for sudden jumps in loudness and brightness, which is what a drum hit, a pluck or the start of a sung syllable looks like, then places each cut just before the jump. Turn the sensitivity down if it cuts in the middle of sounds, or up if it misses quieter hits. Smooth pads and long held notes have no clear hits, so mark those chops by hand.
Are the BPM and key in the file names accurate?
They are estimates from the same analysis that powers Beat Lab, and they are usually right on loops and full beats. Very short chops (under about four seconds) don't have enough beats to measure tempo, so they use the whole file's BPM, and one-shot drum hits often have no real key. Always check by ear, and rename a chop if you know better.
Does pitch shift change the length?
Yes. It works like a classic hardware sampler: raising a chop by 12 semitones plays it twice as fast, so it is half as long, and lowering it makes it slower and longer. That is the sound producers expect from repitched vocal chops. When you set a tempo-synced loop length, the tool allows for the pitch change.
16-bit or 24-bit, 44.1 or 48 kHz?
Choose 24-bit for production: it keeps more detail when you process the sample further. 16-bit files are smaller and play in every app and device. 44.1 kHz is the music standard; choose 48 kHz if your project or video work runs at 48 kHz. Every app listed above reads all four combinations.
Can I sample any song?
Only audio you own or have the rights to: your own recordings, loops and beats you licensed, or royalty-free sounds whose licence allows sampling. Sampling a released song without clearance from the label and publisher can get your track blocked or claimed on streaming platforms, even if the sample is short. The Sample Maker doesn't download from YouTube, TikTok or any other link.
Is my audio uploaded anywhere?
No. The recording is opened, chopped and saved inside your browser. The ZIP is built on your device too. Nothing is sent to Centertainment, so unreleased vocals and beats stay private.
Terms of use and copyright
- Only process audio you own or have permission to use: your own recordings, beats you have licensed, or tracks whose licence allows editing. Removing vocals, cutting or converting a song does not give you any rights to it.
- Don't publish, sell, stream or perform results made from other people's music without permission from the rights holders. Platforms may mute, block or claim such uploads, and you are responsible for how you use what you make.
- Audio Lab does not download or fetch audio from links (YouTube, TikTok, Instagram, Spotify, Audiomack, Boomplay or anywhere else) and does not host any music. You choose files that are already on your device.
- Your files are processed in your browser and never uploaded to Centertainment. We don't see, store or keep copies of your audio. Voice notes may contain other people's voices: respect their privacy.
- The tools are provided free and "as is". Results are automatic and can contain artefacts, so check them before you share, and keep your original files.
Three ways to chop
- Drag: drag across the waveform to mark exactly the part you want, then fine-tune the start and end in milliseconds.
- Tap in time: press Play and hit “Chop at playhead” on each sound, the way you would finger-drum on an MPC or SP-404. Each tap closes the last chop and starts the next.
- Auto-slice: one press finds the hits (kicks, snares, plucks, the start of each sung word) and cuts between them. Use the sensitivity slider to catch more or fewer.
Shape each chop
Tap a chop to open its controls. Edges snap to the nearest zero crossing so the sample starts and ends without a click, and a short fade-out is added by default. You can normalise each chop to a consistent peak level, reverse it for risers and swells, and shift it up or down by up to 12 semitones. Pitch works like a classic hardware sampler, so a chop pitched up also gets shorter and brighter: the chipmunk vocal-chop sound used across Afrobeats, amapiano and hip-hop.
Use Loop preview to hear a chop repeat. For loops, set the length to 1, 2, 4 or 8 bars and the end point locks to the detected tempo, so the loop drops straight onto your project grid.
BPM and key in every file name
When you load a file, the sample maker estimates its tempo and key with the same analysis as our Beat Lab BPM and key finder. You can also detect them for a single chop. The result goes into the file name, for example mypack_vox_01_112bpm_Fmin.wav, so your packs stay organised and you can find a matching sample fast. Tempo needs a few seconds of audio to measure, so very short one-shots use the whole file’s tempo; always trust your ears over the label.
Export for any DAW or drum pad
Download a single WAV or the whole pack as a ZIP with a short README that lists each sample’s length, tempo and key. Choose 24-bit for production or 16-bit for the smallest files, at 44.1 kHz or 48 kHz. The files open in FL Studio, Ableton Live, Logic Pro, GarageBand, BandLab, Koala and hardware samplers.
Sampling and copyright
Use only your own recordings or audio you have the rights to: your vocals and instruments, beats and loops you licensed, or royalty-free sounds whose licence allows sampling. Lifting a piece of a released song, even a second or two, usually needs clearance from both the label and the publisher, and streaming platforms can block or claim tracks that use uncleared samples. The sample maker never downloads audio from YouTube, TikTok, Spotify or any other link; it only works with files already on your device.
Need to tidy a recording first? Clean up hiss with the noise cleaner, trim a long take with the MP3 cutter, or pull a rough instrumental from your own mix with the vocal remover. A Pro version with batch pack export, longer files and stem-based chops is planned: join the waitlist below.
