The sound engineer engaged in restoration work will always use such classical sound processing means as static and dynamic filters, equalisers, compressors, expanders, limiters, reverberators, etc. He should not forget about scissors and scotch for splicing the magnetic tape.


All the above-mentioned means have been integrated into computer software, thus enhancing sound engineer's abilities for more sophisticated sound processing. Just imagine that you do not need any more to record sound over and over again from one tape to the other letting it through various devices. Now sound processing is achieved by means of mathematical algorithms that totally exclude any new noise formation. For example, it is possible to cut out a 48 to 52 Hz noise having depth of 90 dB without corrupting amplitude and phase characteristics of the neighbouring frequencies.

The more sophisticated problem, which can not be solved even with the help of digital filtration, is the broadband noise suppression.

Combined efforts of mathematicians, programmers and sound engineers highly experienced in phonogram restoration have resulted in the Creation of the Sound Restoration System "Kanon" able to solve this task.

The System allows to considerably lower broadband noise level with the initial signal-to-noise ratio of just 9dB! In addition to that the System automatically suppresses modulation noises and corrects some types of non-linear distortions. Naturally, "Kanon" provides for elimination of clicks and noises resultant from scratches on vinyl discs, electrical crackling, magnetisation of analogue recorders and other reasons.

"Kanon" System is really a filigree device allowing to "cut off" only the unnecessary elements which spoil the phonogram perception without damaging important spectrum areas. You can test the System quality simply by hearing music samples included in this catalogue. Please, treat this CD just like a normal music CD, but ignore the first track. Furthermore, we are ready to provide you with any additional information and recording samples upon request.

Our high-skilled specialists are ready to restore your phonograms using the most advanced technology of noise suppression realised in "Kanon" Sound Restoration System.
