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 Robinson’s Web site.
iTunes can be found at Apple’s Web site.
