DUY has launched an audio plug-in trio, the DUY|31, consisting of its DUY31|graphic, DUY31|analyzer & DUY|noiser for TDM (Time-Division Multiplexing) and Mac OS X based systems. The DUY|graphic plug-in is a 31-band linear-phase graphic equalizer, with fader controls covering a dynamic range of 48 dB. The DUY31|analyzer is a spectrum analyzer which provides a visual representation of the audio signal over 31 bands. The third plug-in, the DUY|noiser generates white and pink noise and can be used with the DUY31|graphic to calibrates audio spaces.

The plug-in trio installs Audio Units (AU), TDM, RTAS, VST & MAS versions for the Mac, requiring Mac OS X 10.3.9 or higher. It costs $350, but is on sale for the remainder of 2008 at $300.
