Signalizer Signal Display

Signalizer is a all-in-one signal visualizing package with a bunch of unique focus-points; real-time audio visualization with optimized 3D GPU graphics, everything being scalable and zoomable gridlessly as well as being arbitrarily precise in both settings and display.

Combined with a rich feature set, Signalizer is suited both for electrical/audio engineers fullscreen-inspecting signals, or for general small windows giving an overview of your audio as you create it.

Description & features

General

Freely resizable window
Fullscreen mode
UI from cpl (including UI, skin and colour customization)
Global presets
Software and OpenGL rendering engines
Pure vector graphics UI
Supports any DPI displays (including Retina)
No load on the audio thread at all
Variable graphic settings, multisampling levels (hardware antialiasing), variable FPS or vertical sync
Each plugin/visualizer has separate sample sizes, colouring for visualization and preset handing
Channel modes including phase, separate, side, mid, left, right etc.

Vector scope

“3D view” of waveform, with time as z-axis
Line or point rendering
Lissajous- or “polar” coordinate system displays
Toggleable auto-gain
Balance- and phase-correlation meters

Spectrum

Precise and classic FFT
Customly developed resonating filter bank, with constant-Q behaviour and windows
Choosable and tunable window functions, including none (rectangular)
Non-power of 2 sizes (freely scaling)
Tunable settings for dsp windows, interpolations etc.
Phase cancellations
Spectrogram or spectral view modes
Freely zoomable in all axes
Logarithmic / linear modes

Oscilloscope

Inter-sample interpolation in different modes, including fluid lanczos
Assortment of triggering methods like zero-crossing, spectral harmonic analysis, peak/enveloping and timing windows
Time, cycles or beat/tempo mode
Overlaid or separate scopes for each channel
Waveform can be painted spectrally with custom colours for each band, with per-sample in-phase precision
Adaptive grid adjustable in density
Freely zoomable infinitely
Features in the work:
Statistics
Graphs over quick/slow RMS, peak values, true peaks, a-weighted loudness etc.

Other

Stable support on Unix and Linux
Multiple views in the same display
Custom vertex- and postprocessing shaders and effects
Scripting support for certain algorithms (like, triggers on oscilloscopes)

Alpha, beta testing

I’m looking for people to test the program. Stability is #1 priority for me, so please report any bugs. Signalizer includes logging of exceptions (see the read me). Next topic of interest is the UI and how it feels to use.
