Announce of Audio Fingerprinting Tools (AFT)

AudioWatermarking.info announces availability of Audio Fingerprinting Tools (AFT) – a proprietary acoustic fingerprinting technology and software solution enabling reliable acoustic matching, comparison and identification of audio by means of very compact, highly representative and resistant acoustic fingerprints (hashes).

Some of the technology feature highlights:

– robust and compact fingerprints
– real-time hashing
– on-the-fly DB updates
– instant search over very large DB
– live stream and file tools
– cross-platform software
– console tools for easy automation and quick deployment on servers
– client-server architecture
– unique, proprietary technology and algorithm

AWT0 (AWT-Zero) – new technology in the AWT family

AudioWatermarking.info announces availability of a new product in the Audio Watermarking Tools family: AWT0 (“AWT-Zero”). AWZ-Zero allows for high capacity, completely inaudible watermarking and signaling over lossless audio PCM channels. It is an ideal, and generally the only solution allowing to protect your extremely short audios such as impulse responses (IR) and short audio samples. AWT0 successfully watermarks wave recordings even below 100ms in length.

AWT2 0.12.00 – major technology update

Major update of AWT2 technology – version 0.12.00 is now available.

  • (Encoder) new ‘-quality’ switch and SDK parameter. The parameter is related to an optional mechanism responsible for preservation of the original signal quality. The quality setting can be from 0 to 10. Zero setting switches the mechanism off. Non-zero settings force the encoder to perform additional signal analysis aimed to further improve original audio signal quality in its parts which are “sensitive to manipulations”.
  • Raspberry real-time audio watermarking SDK and example are available

Refer to the full changes log.

AWT2 0.11.05 – major technology update

Major update of AWT2 technology – 0.11.05

  • now the CLI encoder tool uses only a fraction of RAM it required earlier. The encoding is now done buffer-by-buffer, and the tool does not load the entire audio file into memory.
  • added support for a “compound payload”, i.e. a sequence of different payloads that are to be embedded at different time-locations within the audio stream. Each payload must be accompanied with the time where the payload should start. Such sequence must be of the following form: time_sec:hex_payload;time_sec:hex_payload;… No spaces are allowed in the compound payload, the semicolon “;” is used as a delimiter. The ‘time_sec’ can be a positive offset (in seconds) relative to the start of the file, or a negative offset relative to the end of file. You can use ‘void’ payload to designate bypass (no watermarking).
  • the decoder now consumes significantly less RAM in sliced analysis operation; can now process even shorter audios
  • improved non-standard WAV files support
  • various bugfixes
