Watermark discovery and removal by a third person is extremely hard.

  Watermark is resistant to MPEG audio compression up to low quality factor (high compression ratio) and to various digital audio processing operations such as filtering, resampling and requantization.

  Watermark detection in an audio file is performed without use of the original audio.

  AudioMark offers approximately real-time watermark casting and detection on a Pentium computer.

  Storage of the detection results is provided.

  AudioMark is user friendly.
