The Dynamic Spectrum Mapper (DSM) plugin is intended to provide multi-dimensional dynamic control over both the spectral response and dynamic characteristics of audio programme, in order to bring a whole new dimension of facility and artistic ability to the sound engineer. The use of novel processing and programme capture algorithms provides the ability to achieve exemplary results in common tasks such as programme compression and enhancement, vocal expression and instrument characterisation very quickly. The ability to capture, modify and re-apply the spectral characteristics of programme is a powerful creative tool in all stages of the production cycle, from recording and mixing to mastering stages.
The DSM is a dynamic compression and expander application. The basic architecture of the plugin is similar in concept to a multi-band compressor and expander, except that the method of band splitting produces far greater frequency resolution in the higher mid and high frequency ranges. Oversampled FFT technology means there's zero phase distortion.
This high frequency spectrum resolution allows a more natural and musical compression, it also provides a high degree of functionality and artistic modification of the programme character. Since the process produces different artefacts to conventional band splitting dynamics applications, a new range of programme character can be achieved, such as tape saturation effects and the softening of high frequency content. The signal is split into multiple bands using an FFT based process. An adaptive dynamic gain control process operates on the effective power represented within each band, before recombination back into the output signal domain.
Manipulation of the threshold curve changes the threshold target level for each band. This allows the frequency content to be modified based on dynamic changes in the signal over both time and rate. Because the dynamic gain control process includes frequency domain information captured from the original programme (as well as user-defined target responses), it provides a large degree of novel artistic functionality.
