About

A no-frills test-signal generator plugin with 7 operation modes:

• Sine Wave 1kHz
• Sine Sweep 20Hz to 20KHz (at most to samplerate / 2) in 10 seconds
• Square Wave 1kHz
• Uniform White Noise
• Gaussian Shaped White Noise
• Pink Noise
• Impulses (1 sample spike) 100 Hz, 0dBFS

The signal level can be varied between -24dBFS and -9dBFS and defaults to -18dBFS.

• For sine level defines the peak-signal (RMS is identical)
• For square-wave generator the level defines the peak-signal (RMS is +3dB)
• For uniform white noise, the level defines the absolute peak (RMS is about -1.8dB below peak)
• For Gaussian shaped white noise and pink-noise, the level sets the RMS (peak is unlimited, though usually less than +12dB above RMS).
