See the groove,
not just the waveform.

Locked to the beat

MIDI Clock sync with Start, Stop, Continue and Song Position Pointer. As a plugin it follows the DAW's transport directly. FREE mode runs at a manual BPM.

Sweep scope

Bar grid, stacked left and right lanes and a bright write head. Windows from a quarter bar to four bars, horizontal zoom and a measurement ruler.

Read the frequency balance

Choose Spectrum (FFT) for a fast Peak or RMS curve with a fading history line, octave smoothing and a frequency readout, or Spectrum (Band) for responsive third-octave bars with peak markers. Both use a black background; the fill and the bars follow your waveform colour. FFT supports stereo, Left, Right, Mid and Side.

In the next release, after 1.0.0 beta 1.

See the stereo image

Polar Sample and Lissajous views reveal channel relationships; Polar Level summarizes the angular level distribution, with correlation and energy balance alongside. Silence and very weak signals are marked as unavailable. Common display gain changes the picture without changing the measurement.

In the next release, after 1.0.0 beta 1.

Three waveform modes

STD, PRECISE and DJ, where colour follows frequency. Display gain up to 64 dB, with optional auto gain.

Latency you can see

Visona Sync puts a bar impulse on the plugin's sidechain, so Visona measures how late the audio arrives after plugins with latency, and draws it on the grid.

Your own studio display

Run Visona standalone on Raspberry Pi with a screen and an audio interface. Keep your scope beside your gear, with full-screen kiosk mode, touch controls and automatic startup. No DAW needed on the Pi.
