testsignal.lv2

testsignal.lv2 is an audio-plugin for generating test-signals in LV2 format.

It has 9 operation modes:

• Sine Wave 1kHz
• Square Wave 1kHz
• Sine Sweep 20Hz to 20KHz (at most to samplerate / 2) in 10 seconds
• Uniform White Noise
• Gaussian Shaped White Noise
• Pink Noise
• Impulses (1 sample spike) 100Hz, 0dBFS
• Impulses (1 sample spike) 1Hz, 0dBFS
• Impulses (1 sample spike) 5s (0.2Hz), 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)

Install

Compiling this plugin requires the LV2 SDK, gnu-make and a c-compiler.

  git clone https://github.com/x42/testsignal.lv2.git
  cd testsignal.lv2
  make
  sudo make install PREFIX=/usr

Note to packagers: The Makefile honors PREFIX and DESTDIR variables as well as CFLAGS, LDFLAGS and OPTIMIZATIONS (additions to CFLAGS).
