AudioWatermarking.info announces release of AWT4 – an audio triggering, signalling and watermarking solution providing time-precise “digital stamping” with high data rate. The technology allows placing/extracting capacious digital codes in audio streams at precise time places to trigger time- and data-specific … Continue reading →

AWT2 0.10.03 is a major technology upgrade. AWT2 now natively supports Dual-Layer watermarking. Two independent watermarks can be embedded into the same audio stream at different stages of audio content distribution. Dual-layer watermarking is available in both AWT2 CLI tools … Continue reading →

I published an open paper that describes a little crazy (but seems to be novel) idea of combining digital sound and QR codes together. The paper briefly describes a new approach that brings quite effective and easy data hiding and … Continue reading →

New AWT2 SDK (0.10.00) is a complete rework of the core encoding engine. It now supports real-time live audio streams encoding with low latency. – Fully rewritten encoder code, backwards/forwards compatible with older decoders – faster encoding, dramatically reduced encoder … Continue reading →

New in AWT2 0.09.04 version: – bugfix in the encoder: noise generation feature (“-noise_level” command line parameter) was ignoring “-skip_first” and “-skip_last” settings; fixed. – improvement in the encoder: “-skip_last” value can be negative, in this case the parameter specifies … Continue reading →

The new AWT2 0.09.00 is a major AWT2 release. Here is what’s new: – AWT2 encoder uses new, redesigned encoding algorithm (backward compatible with the older one). The new algorithm features new “-modulation_gain” parameter that triggers an additional modulation mechanism … Continue reading →

Updated AWT1 package with critical fix in GUI. What’s new: introduced “-no_limiter” command line switch in the encoder, allowing to force normalizing the output audio instead of limiting it fixed critical bug in the GUI front-end: “-auto_answer=a” switch was not … Continue reading →

Audio Watermarking Tools 1 (AWT1) is another product that is now offered at AudioWatermarking.info. AWT1 is a watermarking solution realizing so called “strict watermarking” approach in the sense that the source (not watermarked) audio data is required in order to … Continue reading →

AWT2 0.08.20 has been released, which is a major release of the software. It brings several significant improvements. Here is a full change log: encoder: – significantly improved encoding speed (2 times faster in ‘normal capacity’ mode @ 44.1 KHz) … Continue reading →

The author of AWT2 has been granted a U.S. Patent No. 8,116,514 for the watermarking technology behind this product.
