T-RackS 24 is a suite of audio mastering tools that's available as both a Pro Tools RTAS (MAC) plug in and as a standalone application for MAC and PC computers. Called "analog-modeled mastering software", T-RackS uses actual physical models of tube circuitry for each of the five included processors. The five are six-band parametric equalizer, tube stereo compressor with stereo enhancer, multi-band limiter, soft clipper and output section. There is a Control panel for transport control of audio files as well as fade in/outs.

The whole purpose of using tubes or tube modelling is to gain a tube harmonic enhancement for your digital music mix. The internal 32-bit floating point processing combined with familiar analog processor front panel controls make using T-RackS fast, intuitive, accurate and easy...without any learning curve necessary. There is a cool scope for visualizing your EQ settings and a Console for setting preferences.
