iTunes can use visual plug-ins that let users watch a visual representation of the music being played, which is synched to the beat of the music. And TechRTA 1.0 is a new, free visual plug-in from Robert Robinson.
TechRTA provides faster transient response, a bigger, more visually engaging display, and more options than the built-in “thumbnail” real-time analyzer of iTunes, according to Robert Robinson of Monmouth. The plug-in will run under iTunes 1.1 for Mac OS 9.x and iTunes 1.1.1 on Mac OS X.
TechRTA uses high-performance 12th order bandpass filters, similar to professional real-time analyzers that cost “hundreds of dollars (or more),” Robinson said. The 31-band capability of the plug-in may be permanently activated by purchasing a US$4 activation key; 10-band capability is free.
Instructions for obtaining the key, more info about the software, and online help are included with the software. You can download TechRTA (a 140k file) at
