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

All tools are built for extreme accuracy and thus can be used in studio applications. Many of the tools are configurable to adapt them to your needs. 

Features: 

- 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.

Release notes:
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.
