What Sample Agent actually is

A search engine for the sounds you already own. If you make music you have folders full of samples: kicks, loops, vocals, one-shot hits. Finding the right one is the slow part. Sample Agent listens to every file on your drive, so you can ask for a sound and have it in your track seconds later, in the music software you already use (your DAW: FL Studio, Ableton, Logic, whichever it is).

  1. 1

    Show it your samples folder

    Wherever your packs live, internal drive or external SSD. It reads everything once, on its own. You don’t rename, tag or sort a single file.

  2. 2

    Ask for the sound you want

    Type a word, describe how it should sound, or point at a sample you like and ask for more like it. It goes by the sound itself, so a badly named file turns up just the same.

  3. 3

    Drag it into your track

    It arrives already at your project’s speed and in your project’s key, so it fits the moment it lands. No stretching, no re-pitching, no guessing.

300 GB of samples. You use 2%. Now use the other 98%

🧠 It listens. Bad filenames stop mattering.

SEARCH

Find it by sound, not by filename

Type screech and you get actual screeches, even if every last one of them is called “Music Loop 07”. Spell it wrong and you still get them: snair finds your snares, because Sample Agent corrects against the words that exist in your library.

Found one you love? Select it and press S. Sample Agent re-ranks by how close each sample sounds to it, across categories, packs and names, and scores every match. Press ← Back to browsing and you are exactly where you were, filters and all.

Find Similar: the library re-ranked by sound, every match scored
LOOP REGION

Drag out only the part you want

Drag across the waveform to mark a section. Loop plays just that part, and dragging it out gives your DAW just that part, already stretched to your tempo and re-pitched to your key. Turn Drag: Rendered off and you get the untouched original instead. Double-click clears it.

ONE-SHOTS

Every loop is also a kit

A loop is a bar or two of music. Open the One-Shots tab and Sample Agent chops it at every hit, so you get the kick, the snare and the hat as separate sounds, each named by note. Click one to hear it. Drag any one of them out on its own. The punch at the start of each hit stays intact, so nothing sounds soft or clipped.

One loop sliced into single hits, each labelled by note and draggable on its own
MIDI

Turns your own audio into notes

MIDI is the notes of a melody rather than the recording, so you can put them on any instrument you like and change them freely. When a pack includes MIDI, Sample Agent shows you the notes, moves them into your key and drags them out next to the audio. When a pack includes none, Generate MIDI works the notes out from the audio itself.

That part is still in beta, and we would rather say so than let you find out. It is sharpest on basslines and single-note melodies. Chords and drum loops come out rougher and usually need a tidy-up. Every other browser we know of hands you a MIDI library, or nothing at all. None of them turns your audio into notes.

TEMPO & KEY

It doesn’t ask your DAW. It listens.

Tell it your track’s speed and key once, and everything you click plays back at that speed and in that key. Drums keep their punch while it happens. That works everywhere: Mac, Windows, on its own or inside your music software. Loaded as a plugin it doesn’t even ask, it just takes the speed from your project and stays in time with it.

Audio Sync goes one better. Run Sample Agent on its own and it simply listens to your speakers, works out the speed and the key of what it hears, and matches everything to that. Nothing to load, nothing to connect, no settings to line up. It just hears your track. That means it follows any music software, FL Studio included, and it is clever enough to ignore its own sound so it never follows itself.

And it doesn’t care what is making the sound. Put a reference track on Spotify or YouTube and audition your own loops straight over it, in time and in key.

Audio Sync needs macOS 14.2 or newer, or Windows 10 build 20348 or newer, and runs in the standalone app only. You don’t need it inside a DAW, because there the plugin takes the tempo from the host.

How it compares

Four ways producers deal with a big sample library. Here is where each one stops.

Sample Agent Subscription sample services Classic sample managers Free library toolsa different app for each job
Works with the library you already own Yes Their catalogue Yes Yes
Buy once, no renewals Yes Monthly, forever Usually Free
Previews already in your tempo and key Yes Their catalogue only Varies In one of them
Searches your own library by how things sound Yes No Some In another
Writes MIDI from your own audio Yes (beta) No No No
Follows your DAW with nothing loaded in the session Yes (standalone) No No No
Everything runs on your own machine Yes No Yes Varies

Free tools are the fiddly column: one app searches, another syncs previews, a third reads tags, and you end up running three. One honest caveat too: one DAW now has similarity search built in, so if you work only inside that one, you already have part of this.

Works in any DAW, and on its own

Standalone app, VST3 and AU plugin. One licence covers all three.

  • Standalone
  • VST3
  • AU
FL Studio, Ableton Live, Cubase, Logic Pro, Studio One, Bitwig and more

Sample Agent is a fast browser for the sample collection you already own. Point it at your folders once. It reads names, tempo, key and the actual sound of every file. From then on the right sample is a search away.

What you're buying

  • Standalone app: the full browser, on its own
  • VST3 and AU plugin: the same browser and library inside your DAW
  • One licence covers all three. Running the standalone and the plugin doesn't use two slots.
  • Your licence key is emailed the moment the payment goes through, and it also sits on the order in your Sample Agency account, so you can copy it any time.

Your licence

  • Perpetual. Buy once. No subscription, no renewal, no expiry.
  • Two computers on one key: your studio machine and your laptop. Mac and PC can share the same key.
  • Free 7-day trial. Full version, no card required.
  • Moving to a new machine? Deactivate in the app, or move the licence yourself.
  • Updates are included at no extra charge.

Files it reads

  • WAV, AIFF, MP3, FLAC and OGG on both platforms, plus M4A, AAC, ALAC and CAF on macOS.
  • A MIDI file sitting next to a loop is picked up as its companion and drags out with the audio, transposed to your key.

System requirements

  • macOS 10.15 or newer, with one universal build for Apple silicon and Intel
  • Windows 10 or newer, 64-bit
  • On macOS the VST3 and AU plugin need 11+, and so does searching by sound
  • Audio Sync needs macOS 14.2+ or Windows 10 build 20348+, and runs in the standalone app only. Inside a DAW the plugin takes the tempo from the host instead

Worth knowing

  • Generate MIDI is in beta: sharpest on basslines and single-note melodies, rougher on chords and drum loops.
  • The app's interface is English only.

Frequently asked questions

Can I try it before buying?
Yes. 7 days, the full version, no card needed. Nothing is crippled or watermarked: it’s the same app you’d buy. Hit Try on macOS or Try on Windows above.
What exactly do I get when I pay?
A licence key, by email, the moment the payment goes through. There is nothing to ship and nothing to wait for. Paste the key into the app you already downloaded for the trial and it turns into the full version on the spot. This is software: a standalone app plus a VST3 and AU plugin. The box and the desktop unit in the photos are renders, not hardware.
Is it a subscription?
No. You pay once and the key never expires. No renewals, no credits, no “your licence has lapsed” email two years from now.
What if it doesn’t work out?
That’s exactly what the 7 free days are for, and we mean it: install it, point it at your real library, and put it through a proper session or two before you spend anything. Nothing is held back during the trial, so what you test is what you buy. If something is broken, or it doesn’t do what this page says it does, write to info@sample.agency and we’ll sort it out with you. Once a key has been issued we can’t take it back. A licence key is digital goods, and that is exactly why the trial is a full one.
Is there a Windows version?
Yes, and it is the same app. Windows 10 or newer, 64-bit. The download is a zip: unpack it and run Sample Agent Setup.exe, which installs the standalone app and puts the VST3 where every DAW looks. Run the installer from the unpacked folder rather than from inside the zip. The one thing Windows doesn’t get is the AU plugin, because AU is an Apple format. VST3 covers Windows DAWs.
What are the system requirements?
macOS 10.15 or newer, with one universal build for Apple silicon and Intel. Windows 10 or newer, 64-bit. A few things need more: on macOS the VST3 and AU plugin need 11+, and so does searching by sound (Find Similar still works below that, just on plain audio analysis). Audio Sync needs macOS 14.2+ or Windows 10 build 20348+, and runs in the standalone app only.
How many computers can I use it on?
Two at the same time: your studio machine and your laptop, for example. Running the standalone and the plugin on the same computer counts as one, not two. Mac and PC can share the same key.
What if I get a new computer?
Deactivate it in the app on the old machine, then activate on the new one. Old machine dead or sold? Enter your key on the new one and choose Move licence here. No email to us needed.
Do I get updates?
Yes. Updates are included, no extra charge. Your key keeps working.
Do I have to tag or organise my library first?
No. Point it at your folders once. It reads the name, the tempo, the key and the actual sound of every file, and sorts everything on its own. You never label a thing.
How big a library can it handle?
Hundreds of thousands of files without breaking a sweat. It scans once, then opens straight from a cached index while it quietly checks in the background for anything you’ve added or removed, so start-up stays fast however big the folder gets.
Which file formats does it read?
WAV, AIFF, MP3, FLAC and OGG on both platforms, plus M4A, AAC, ALAC and CAF on macOS, where the system decodes them for us. MIDI files sitting next to a loop are picked up as its companion, so the notes drag out with the audio.
Can my library live on an external drive? And do my favourites survive a reinstall?
Yes to both, and that’s how most big libraries live anyway. Point it at a folder on an external SSD and it works the same. Scanning is just as fast as the drive is. Favourites, colour labels, saved searches, corrected tempos and keys are all kept separately from your audio files, so reinstalling the app doesn’t touch them.
Which DAW does it work with?
Any DAW. Sample Agent runs as a standalone app and as a VST3 and AU plugin, and drags audio and MIDI into anything: Ableton, FL Studio, Logic, Cubase, Studio One, Bitwig. Loaded as a plugin it reads the tempo straight off the host transport, so previews are in your project’s tempo without you setting anything.
What exactly can Audio Sync listen to?
Anything your computer is playing. Your DAW, any DAW, FL Studio included, but also a reference track on Spotify or YouTube: it works out the tempo and the key and locks your previews to both, so you can audition loops straight over whatever is on. It ignores Sample Agent’s own preview, so it never chases itself. Audio Sync needs macOS 14.2 or newer, or Windows 10 build 20348 or newer, and works in the standalone app only. You don’t need it inside a DAW, because there the plugin takes the tempo from the host.
How good is the MIDI generation?
If the pack ships MIDI, Sample Agent just shows it, and that is exact. Generate MIDI is for when it doesn’t: it writes MIDI from the audio and is still in beta. It’s sharpest on basslines and single-note melodies; chords and drum loops come out rougher and usually need a tidy-up. Try it on your own packs during the 7-day trial and see.
Do you upload my samples anywhere?
No. Not one file, not one filename, not a fingerprint of either. The index, the search and the sound analysis all run on your machine, and nothing about your library is sent to us or to anyone else.
Is the app in my language?
Not yet. The app’s interface is English only, even though this shop speaks five languages. It’s a small vocabulary of studio words most producers already use, but we’d rather you knew before you bought.
