Are there any EQ plugins with a real time spectrum analyzer

I’m trying to EQ drums and it’s just difficult using filter curve when I can’t see what frequencies are present. Is there a plugin that exists that has a real time spectrum analyzer?

TDR Nova is the best freebie I’ve seen:
it’s a EQ/Compression plugin which can show the real-time spectrum of input or output …

Thank you! exactly what I was looking for. Just got it works great.

Eventide SplitEQ maybe?
There is a new structural technology in this plugin. Eventide describe this technology very well.

$99 and 64-bit only.

whereas TDR Nova has a free version, and is available in 32 & 64-bit.
