This is a homepage of Audio Watermarking Tools (AWT) — robust sound watermarking software solutions based on a proprietary patented* technology. The tools come in form of file-to-file console (CLI) applications with intuitive GUI front-end. The tools are cross-platform, easy to use on workstations and quickly deployable in server environments. AWT are free to try.
Digital audio watermarking allows to imperceptibly embed (hide) digital signature into audio content (audio file) so that this information cannot be removed without damaging the original audio quality. The embedded inaudible information can be used to verify authenticity of the audio content, identity of its owners or recipients.
Two different audio watermarking products are offered:
Audio Watermarking Tools 2 (AWT2) — a watermarking solution realizing so called "blind watermarking" approach in the sense that the watermark can be extracted directly from the watermarked audio recording (the source audio is not needed).

Audio Watermarking Tools 1 (AWT1) — a watermarking solution realizing so called "strict watermarking" approach in the sense that the source (not watermarked) audio data is required in order to find and decode watermark in the watermarked recording. Watermark extraction is performed by “comparing” source and watermarked streams.
