What is it?

TrustedAudio (TA) is a professional web-based tool that provides an easy and reliable way to share, deliver, and distribute audio files securely by means of watermarking and digital signing.

Simply log in, upload your audio files, fill in the recipients' info, and send the files! All recipients receive their own uniquely and inaudibly watermarked ("digitally signed") copy of each distributed audio file, ensuring your copyright.

Unique watermarks are embedded into acoustic content of every audio file copy delivered to each individual recipient. Records of each watermark, together with the file meta-data and the recipient info associated with the delivered file, are securely stored in the TA database, enabling the file owner to identify and backtrace delivered copies at any time, instantly and reliably.

A user can choose to make a signature public; in such case any TA visitor will be able to authenticate the track by analyzing even a short fragment of it and retrieving its copyright information.


Who is it for?

For musicians, recording studios
and music labels

Send watermarked music promos and releases to your desired recipients without fear of piracy; you can backtrace the pirate and easily identify the leak source by retrieving the hidden digital signature with the recipient's info from any fragment of your watermarked music.
Claim your authorship by watermarking your track with a publicly retrievable digital signature before sharing it with the world; anyone interested will be able to authenticate your track by retrieving its signature directly on the TA front page.
Got your own web store? Easily integrate it with TA, and start selling watermarked tracks to prevent piracy.
