Spectre

Spectre is an exceptional real-time audio analyzer software designed for Mac OS X that is geared towards live audio analysis. Built using the latest Cocoa technology, Spectre made sure to take advantage of the most solid OS X interface features such as CoreAudio, Quartz, OpenGL, and more. The software boasts nine different multi-channel and multi-trace meters dedicated to audio analysis that can have any number of indicators and traces.

Each trace can further be customized by adjusting the input channels, mixing, ballistics, filtering, and color, all while retaining transparency. You can have as many meters or copies of meters as you need, and the software allows inputs from audio hardware and network sources. Spectre can even receive audio from any Audio Unit insert on your multitrack by using Apple's AUNetSend/AUNetReceive Audio Unit pair that runs on the same or another computer.

The software is incredibly flexible and accurate in its display. Every meter comes with useful factory presets, and you can easily save and customize the meter settings or sets of meters to your liking. The display is optimized using Quartz, OpenGL, and clever memory management, allowing you to resize each meter in real-time without any interruption.

In conclusion, Spectre is a must-have software for any audio enthusiast who requires real-time audio analysis. Its flexible and accurate display, in combination with its extensive customization options, make it the go-to software for every live audio analysis requirement.
