Analysing audio fingerprint…
About royalty-free vocals & samples: If your track includes licensed vocal samples or loops from sample packs, a match may appear even though your use is completely legal. These samples may have been used in other released songs. Always listen to the matched track on YouTube to verify whether it is a true match.
What is a Music Copyright Checker?
A music copyright checker is a tool that compares your audio track against a database of commercially released songs using audio fingerprinting. Unlike metadata searches, audio fingerprinting analyses the actual sound of the music — so it can detect a match even if the file name, tags, or format are completely different.
This tool is powered by ACRCloud, one of the world's largest audio recognition databases, covering hundreds of millions of tracks across major streaming platforms and record labels.
Why Check Music for Copyright?
Whether you're a DJ buying exclusive ghost-produced tracks, a producer selling beats, or a label A&R vetting unsigned artists — knowing a track is truly original is critical. Uploading or streaming a commercially released song without a licence can result in:
- YouTube Content ID claims and revenue loss
- Streaming platform takedowns (Spotify, Apple Music, Beatport)
- Legal action from rights holders and collecting societies
- Permanent bans from distribution platforms like DistroKid or TuneCore
Running a copyright check before release, purchase, or upload takes seconds and can save you from expensive legal problems.
How Does Audio Fingerprinting Work?
Audio fingerprinting works by extracting a compact acoustic signature — called a fingerprint — from a short segment of audio. This fingerprint captures unique spectral and rhythmic characteristics that survive format conversion, EQ changes, and even minor pitch shifting. The fingerprint is then compared against a reference database of known recordings.
ACRCloud's system was built for broadcast monitoring and is used by major TV stations, streaming platforms, and digital distributors worldwide. It processes millions of identification requests every day.
Understanding the Confidence Score
When a match is found, ACRCloud returns a confidence score from 0 to 100. A score of 85 or above indicates a high-confidence match — meaning the tool is very likely correct. Scores below 85 may indicate coincidental similarities, e.g. two tracks sharing the same royalty-free drum loop or chord progression.
This tool only flags results with a score of 85 or above to minimise false alarms. If your track uses licensed vocal hooks or industry-standard sample packs, a match at this threshold still warrants careful listening to the referenced track.
What to Do If Your Track Matches
- Click the YouTube link provided in the result to listen to the matched recording.
- Compare the matched section carefully — is it genuinely the same melody or production, or a coincidental resemblance?
- If you used a royalty-free vocal or loop pack, check whether the matched song also used the same sample. If so, your track is likely fine for release.
- If the match is a full song copy or an unlicensed interpolation, do not release or sell the track.
- If you are still unsure, consult a music lawyer or contact the rights holder directly.
Who Should Use This Tool?
- DJs — verify that tracks purchased as exclusive or white-label have not been previously commercially released.
- Ghost producers — confirm your tracks are original before selling or delivering to clients. Learn more about our custom music production services.
- Record labels & A&Rs — quickly vet demo submissions for potential copyright issues.
- Content creators — check background music before using in YouTube videos or social media.
- Music distributors — pre-screen submissions to avoid platform takedowns.

ACRCloud identifies tracks with very high accuracy for commercially released music. The tool only shows a warning for matches with a confidence score of 85 or above to minimise false positives. However, no system is 100% foolproof — always listen to the matched track yourself before making a decision.
Yes, this is possible. Popular royalty-free vocal loops and drum samples from packs like Splice, Looperman or Loopmasters may appear in many commercial releases. If your track uses one of these licensed samples, the copyright checker might flag it as a match. This does not mean your track is infringing — it means the referenced sample was also used in the matched song. Listen to the YouTube link to confirm.
A clean result means no match was found in ACRCloud's database at the time of the check. It does not guarantee full originality. The database covers most major commercial releases, but it may not include every obscure release, re-edits, or recently released tracks that have not yet been indexed.
The tool supports MP3, WAV, FLAC, AAC, OGG and M4A files up to 50 MB. For best results, use a high-quality MP3 or WAV at 44.1 kHz.
A small audio sample (approximately 1 MB taken from the middle of your file) is temporarily sent to the ACRCloud recognition service for fingerprinting. It is not stored, logged, or shared. The rest of your file remains on your device.
Yes. WAV, FLAC, AAC, OGG and M4A are all supported. The audio fingerprinting works on the raw audio content regardless of the encoding format.
