Digital Real Time Analyzers

[coolwhip]

On the software side, I use this free plugin for real time spectrum analysis:

rnd | inspector

Here's a couple more if that doesn't work for you:

Blue Cat's FreqAnalyst - Real Time Spectrum Analysis Plug-in (VST, Audio Unit, RTAS, AAX, DX) (Freeware)
VertexDSP - MultiInspectorFree

Signal Scope

Two standalone (non-VST, non-AU) analyzers I use regularly:

TrueRTA can do 1/1, 1/3, 1/12, 1/24 octave analysis, at prices up to $99. The latter modes are useful as there are 12 notes to (most) octaves. 1/3 is good for setting up speakers in a new environment and general sound balancing. Very easy to use.

Sonic Visualizer is free (rather: paid for by the EU taxpayers) and has a lot of different analysis plug-ins available. Too many to list, but I last used it recently to determine the pitch ranges of the toms in a drum library (as IMHO toms should always be tuned to the scale thr music is in).

I like SignalScope the best. Runs on your iPhone. Very detailed, although it is limited by the frequency response of the microphone (primarily at the low end, below 100Hz).

Since you use Logic 9, when you pull up the EQ on a channel, click on the little blue "Analyzer" button. This will show you a real-time frequency analysis of the track.

Thank you all for the suggestions!
