Freelance engineer Sean Sullivan has toured with Sean “P. Diddy” Combs, Justin Timberlake, Jennifer Lopez and 98 Degrees and is currently on tour with Jessica Simpson.
The real-time analyzers most touring vendors send out are simple LED units with few features or functions — not much help if you want to measure the room in 20 different spots and save 20 different presets of what the room looks like. I use [Metric Halo's] SpectraFoo, which can re-create a third-octave — style analyzer, but being software-based, it can memorize as many snapshots as I want. I can also send my console solo cue bus to it and use SpectraFoo's phase scopes. For interfacing several sources from my console to a laptop (which lacks multiple inputs) to run SpectraFoo, I use [Metric Halo's] Mobile I/O. This turns your laptop into a miniature console, with eight analog I/Os, and AES and S/PDIF digital I/Os. With that setup, you have a little matrix mixer and everything a console would have, except there's no surface.
