Spectre Starter 1.5

Spectre Starter is a multi-instrument real-time audio analyzer for Mac OS X. Designed in Cocoa from the ground up, Spectre Starter proudly takes advantage of Quartz, OpenGL, CoreAudio, and other solid OS X interface features.
Spectre Starter is a simplified version of Spectre that is designed for students and beginners. It offers the Level, VU, Oscilloscope, Spectrograph, Spectrogram, Waveform, Lissajous and Numerical meters. It's priced for students and beginners. Each meter can have any number of traces or indicators, and each trace can have it's own number of input channels, gain, mixing, filtering, ballistics and color (including transparency). You can have as many meters (or copies of meters) as your screen will allow! Spectre Starter also gives you very precise control over color gradients.
