This is a homepage of Audio Watermarking Tools (AWT) — robust sound watermarking and steganography 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 are quickly deployable in server environments. AWT are free to try.
Three different audio watermarking products are offered:
(FEATURED!) 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.
(NEW!) Audio Watermarking Tools 3 (AWT3) — an audio trigger codes and watermarking solution especially designed for using in acoustic front-end applications requiring transmission of digital codes over-the-air (e.g. retail stores) and also in so called "second screen" applications. AWT3 is a direct extension of AWT2 and is fully based on its patented technology. Details and demo (including Android app allowing to detect watermarks over-the-air) are available upon request.
