To add to my previous comment:
The tool has already proven really usefull. There's this rather popular YouTube-channel from which I already knew the audio-logo used in the videos there was an illegally obtained AudioJungle-item. Long story, I just know. I however never knew who the original author of the item was - so there never was much I could do about this violation. Now with the availability of this great, great tool: I started to play a video, recorded a part of the audio-stream, saved it as MP3 and sent it over to the tool. And there it was: the original author indeed. I can now continue on handling this violation, by informing the author and sending a more detailed report to Envato.
To say it again: this tool, if passing extensive testing, makes for an unmissable asset to the Envato marketplace!
EDIT: this once again shows the brilliance of this marketplace/community. There's so much creativity and talent, so many brilliant people to meet, so much to learn from eachother, so much to work on together. It's amazing.
