SignalSpy is a suite of powerful tools that let you analyze audio signals. Included are an oscilloscope, a spectrum analyzer, level indicator and spectrogram.

  • Four highly accurate audio signal analyzers.
  • The oscilloscope can be synchronized to your waveform using a trigger level.
  • Frequency scale configurable between logarithmic and linear.
  • Very fast screen updating giving you a true real-time display.

  • What's New
    This version brings some important bug fixes and improvements:

  • A completely rewritten rendering engine with greatly improved performance. Now you can open a lot of analyser windows next to each other without a drop in frame rate.
  • Improved appearance of the oscilloscope and spectrum analyser on Retina displays.
  • We fixed a crash caused by some higher end audio devices having a default sample rate that is not 44.1 KHz.
