Reverse Sound Search: Searching by Sound
Last updated July 13, 2026
Normal search runs on words: you type what you want and hope the tags and filenames agree with you. Reverse sound search flips that around. Instead of describing a sound in text, you hand the search the sound itself, and it finds more that resemble it. For producers and composers — who almost always have a reference in hand and rarely have the right word for it — that is a far more natural way to dig. This guide explains what reverse sound search is, how it works under the hood, and how to use it to find sounds you can actually keep.
Try it now: drop any clip into reverse sound search and get cleared samples that resemble it — public domain and CC0, ready to use.

Reverse sound search — also called reverse audio search or searching by sound — is search where the input is audio, not text. You give it a clip, and instead of returning pages that mention a keyword, it returns sounds that resemble the one you gave it. It is the audio equivalent of a reverse image search: the query is the thing itself.
That matters because the hardest sounds to find are the ones you can hear perfectly but cannot name. Reverse sound search removes the naming step entirely.
How it works: fingerprints vs embeddings
There are two flavors, and the difference decides what you get back. Fingerprinting matches your clip to one exact known recording — this is what a song-ID app like Shazam does, and it answers “what is this.” Embedding similarity turns your clip into an acoustic profile and finds everything that sounds like it — this is what people usually mean by reverse sound search, and it answers “what resembles this.”
Most digging wants the second kind: not the single record that matches, but the field of sounds that feel related. We break the two apart in reverse audio search vs Shazam.
What you can search for
- Full musical phrases — a loop or a bar whose mood you want to echo.
- One-shots and hits — a snare, a stab, a key you are chasing.
- Sound effects and foley — see find similar sound effects.
- Textures and atmospheres — drones and beds matched by feel, not label.
Why producers and composers use it
The workflow fits how music actually gets made. You hear something you love — in a record, a temp, an old film, a field recording — and you want that energy in your own work. Typing tags to approximate it is guesswork; handing over the clip is not.
It also quietly solves a rights problem. The reference you love is often copyrighted and hard to clear, so chasing that exact record is a dead end — see how to find the sample in a song. Reverse sound search points you at cleared sounds that resemble it instead, which you can keep.
Search by sound on Selekt
Drop the Needle is Selekt's reverse sound search. You drop in a clip and it returns cleared samples that sound like it — every match public domain, CC0, or CC-BY, each with a license certificate per download. It reads your clip's BPM and key so you can filter matches to a compatible tempo or key, and you can keep pulling “more like this” on any result to follow the thread.
Getting better matches
- Trim tight. Give it the single most characteristic moment, not the whole track.
- Pick the tell. Choose the part that carries the feel you want echoed — the groove, the texture, the hook.
- Use the tempo and key filters. Steer matches toward something that drops straight into your project.
- Follow the thread. When a match is close, search from it again to close in on the one.
Give reverse sound search a clip and it hands back cleared samples that resemble it — nothing to license, ready to build on.
Search by sound →Frequently asked questions
What is reverse sound search?
Reverse sound search is searching by audio instead of keywords. You give it a sound clip and it returns other sounds that resemble it, ranked by similarity — the audio equivalent of a reverse image search.
How is it different from Shazam?
Shazam fingerprints your clip to identify one exact known recording. Reverse sound search uses acoustic similarity to find many sounds that resemble your clip. Shazam answers "what is this"; reverse sound search answers "what sounds like this."
What can I search for?
Musical phrases and loops, one-shots and hits, sound effects and foley, and textures or atmospheres — anything with acoustic character. Because it matches by sound, it handles the sounds that are hard to describe in words.
Are the results cleared to use?
On Selekt, yes. Every match returned by Drop the Needle is public domain, CC0, or CC-BY, and each download includes a license certificate documenting where the sound came from.
Is it free?
Yes. Reverse sound search on Selekt is free with a free account — no credit card and no trial — and browsing and downloading the cleared catalog is free too.
Key takeaways
- Reverse sound search takes a sound as the query and returns sounds that resemble it — search by audio, not words.
- Fingerprinting identifies one exact recording; embedding similarity finds many resemblances — the latter is what digging usually wants.
- It fits how music is made: you have a reference you love and want that energy in your own work.
- Chasing the exact copyrighted reference is a dead end; reverse sound search points you at cleared look-alikes you can keep.
- Selekt's Drop the Needle returns cleared, tempo- and key-aware matches, and is free with a free account.
