Available IIR filter options include parametric EQ, peaking, shelving, tone control, Butterworth, Bessel, notch, and all-pass. IIR filter coefficients can also be entered directly if they are generated in another tool. .

Two-way and Three-way crossovers are available as dedicated blocks in SigmaStudio's library. Crossover types can be selected from Linkwitz-Riley, Butterworth, or Bessel topologies, and a graphical display of the overall frequency response is shown in the crossover window.

Mono and multi-channel dynamics processors are available with a peak detector driving the look-up table.

Mono and multi-channel dynamics processors are available with an rms level detector driving the look-up table.

A limiter is a simpler version of the dynamics processor which will compress the signal above a specified threshold.

The chime designer allows you to design a custom frequency sweep envelope and amplitude envelope for a sine tone output.

The Dynamic Bass boost block provides input level-dependent bass boost. Lower level signals are boosted more than higher-amplitude signals. Using a variable-Q filter, this algorithm dynamically adjusts the amount of boost.

With Midnight Mode, loud sections of an audio signal are attenuated and very quiet levels are readily raised into audibility, while dialog remains unchanged and intelligible. This permits higher overall levels with better clarity for the intended active listeners, especially in television applications, with much less chance of disturbing nearby non-listeners.

The SuperPhat block is an advanced algorithm that allows for a wider stereo image to be played back from two closely spaced speakers. This spatializer algorithm is only meant to widen signals that are already in stereo format, in order to enhance the image. The function is similar to the Phat-Stereo algorithm but performs a more advanced implementation of the algorithm to achieve a better effect. .

Enhanced Stereo Capture is a record-side algorithm which creates a wide stereo image from two closely-spaced microphones.

The Wind Noise Reduction block will detect and remove wind noise from a two-microphone input signal.

Controls the volume setting based on push-button inputs. This includes programmable hold and repeat, as well as two-button mute.

Controls the volume setting based on the input from a rotary encoder.

The index selection of a table of value can be changed based on two control inputs. One input will increment the index pointer and the other will decrement the index.

The real-time rms or peak level of any signal in the SigmaDSP can be measured and read back through the control port. SigmaStudio will also graphically display a level meter in the design.

With a hard clipper, input signals will be limited to a fixed threshold setting.

With a soft clipper, input signals will be limited based on a threshold setting, but the clipping will not introduce as much distortion as a hard clipping.

SigmaStudio supports heirarchical designs to create a cleaner graphical signal flow. Processing blocks can be saved in nested heirarchical boards to be grouped by similar function, or to enable quick reuse of commonly-used signal flows.

The magnitude and phase response of filters implemented in SigmaStudio can be displayed in real-time. Responses of single filters or a series of cascaded filters can be displayed in the same window.

SigmaStudio can import MLSSA files and display a speaker's frequency and phase response in the probe window. This visualization can be used to tune the overall response of the system to a desired target.
