Riffhold answers one question: is this upload one of our tracks? This demo shows the whole loop in three steps.
First you add an original. You upload the audio file, or paste a link to it, and Riffhold turns it into an acoustic fingerprint plus file hashes. The audio itself is deleted once the fingerprint is made, so what stays in your catalog is a compact description of the recording, not the recording.
Next, someone uploads a copy. In the demo it is promo-cut-v3.mp4: a 31-second excerpt inside a video, re-encoded at a lower quality. An exact-file check would miss it, because the bytes are different. Riffhold compares the file and its segments first, then the acoustic fingerprint, against your catalog and nobody else's.
Then you get the verdict. Here it is Protected, with a confidence of 91, the matched track (Harbour Lights) and the span that lines up: 0:41 to 1:12 of your original. Those seconds are what you need to decide what to do next, whether that is a takedown request, a licence conversation or simply letting it through.
Every check ends in one of five words: Owned, Protected, Review, Own duplicate or Clear. Owned and Protected are strong matches you can act on. Review means a person should listen, for example when your music sits under speech. Clear means nothing in your catalog matched. A match is evidence for a person to look at, not a legal ruling.
