40-bit floating point processing
For an exact calculation of the audio signals, a 40-bit floating point resolution is used internally
Different signal processing modules available, e.g. ISOSTEM-Upmix
The XDSP card can operate up to two Isostem upmix algorithms to display stereo signals such as finished mixes in surround.
Level and delay adjustment
Level and delay controls are configurable.
The equalizer unit consists of both low/highpass and two shelving filters as well as four bell filters. All bands can be changed in frequency from 20Hz to 20kHz and with +/-24dB gain. The slope of the bandpass and cowtail filters can be selected in 6dB steps of 0dB-24dB, the quality of the bell filters can be between 0.5 and 9.
Blocking filter (high/low pass, bandpass, all-pass filter (90°)
For many applications, no complex equing is required, only blocking filters that are conveniently applied by the XDSP card.
Dynamic processing (compressor, limiter, expander, gate, de-esser)
Common dynamic modules can be set up and operated by the user.
For e.g. extensive public address systems there is the possibility to set up crossovers on the XDSP board.
The XDSP card can also be used for total matrices.
A level/delay matrix can be created for sound reinforcement tasks requiring a large number of distributed loudspeakers.
The configurable N-1 matrix eliminates the need for a mixing console for conference calls.
