Two programs are always employed in the application of our watermarking technology. The additional information is introduced into the audio signal with the watermark embedding software. This software is available for different audio formats.
ContentMarkPCM permits embedding of watermarks in uncompressed audio signals. The audio formats supported are PCM, AIFF and WAV/RIFF. The result of processing is still uncompressed audio files that are provided with watermarks.
ContentMarkPCM is available for Windows and Linux operating systems and a Mac OS-X version is available on request.
ContentMarkCD is a specialised form of the product ContentMarkPCM. With the help of ContentMarkCD, it is possible to create any number of copies of an audio CD, all of which have a different watermark. The program also supports the printing of CD labels including information about the particular recipient. The recipient of an audio CD made with ContentMarkCD is thus aware that the audio CD in question was made especially for him.
ContentMarkCD is Windows software and currently only runs in conjunction with CD/DVD recording solutions manufactured by Rimage.
ContentMarkFLAC processes audio files which have been created with the free lossless Audio Codec, FLAC. ContentMarkFLAC is also a specialisation of the product ContentMarkPCM, since here the audio files are first decoded with the FLAC decoder, before the watermark is introduced. However, the user does not need to manually perform the decoding and the subsequently required FLAC coding, the ContentMarkFLAC-software takes over the control.
ContentMarkFLAC is available for Windows and Linux operating systems and a Mac OS-X version is available on request.
ContentMarkMP3 is a product for embedding watermarks in existing MP3 audio files. The format is not changed by the watermark. So after using ContentMarkMP3, the MP3 audio file still conforms with standards and can be played on any MP3 player or any MP3 player software that also accepts the original MP3 file.
The embedding of the watermark thus takes place directly in the MP3 domain, so the audio signal is not completely decoded beforehand. In this way, transcoding effects which could reduce quality are avoided. ContentMarkMP3 thus delivers the best possible audio quality and robustness of the watermark.
ContentMarkMP3 is available for Windows and Linux operating systems and a Mac OS-X version is available on request.
The software for watermark detection is compatible with all above named products. So, if different audio formats are provided with a watermark using our technology, it is not important to know when analysing a watermark which watermark embedding software was used in a particular case.
The watermark detection software is also available for Windows and Linux operating systems and here also a Mac OS-X version is available on request.
