| DeScratcher PlugIn | Sound LaundryÖ 2.5 |
« DeScratcher PlugIn works virtually without artifacts, providing the correct
setting for all parameters.
Since the CPU requirement of the DeScratcher PlugIn is very low (about 20% on an old 133 MHz Pentium for a 16 bit, stereo, 44.1kHz .WAV file), you can optimize all the parameters while listening to the processing in real-time. With today`s PCs all the remaining Sound Laundry PlugIns can be chained to the DeScratcher for complete real-time filtering of your audio material. You can even use this combination for cleaning live old records, by connecting your turntable (assuming, it is equipped with an appropriate pre-amplifier) to the input of your sound card and its output to your stereo system.
The descratching algorithm consists of two main parts: the declicking filter and the decrackling filter. While the declicking filter is used to remove heavy clicks from old shellac and vinyl records or switching noise coming from audio equipment, the decrackling filter removes any remaining small clicks and crackles.
The scratch scope and the scratch level meter help you to find the optimal setting for the declick and the decrackle parameter. Advance parameter like shape, click sense, and crackle sense are useful to minimize the occurrence of artifacts if working with difficult audio material. We recommend you to perform final precise real-time parameter optimization with a critical listening to the signal removed with the descratching algorithm by using the difference feature of the PlugIn-Station.
The DeScratcher provides well defined application profiles which preset the internal parameters and external advanced parameters helping in typical restoration situations: digital spikes, shellac and vinyl.
In addition to its main task, removal of clicks and crackles, the DeScratcher PlugIn successfully smoothes any kind of distortion causes by signal overload (clipping).
