I'm looking for a freeware (not shareware) VST effect that functions with low CPU and low latency as an RMS meter. I have plenty of peak meters, just no RMS.

Does one exist? Thanks

Try the PSP VintageMeter from PSPaudioware.com

Does anyone know if there is an AU version of the VintageMeter? The product page says there is, but it's no where to be found on the download page.

Thread resurrection,
but thought I'd point out that the freeware RMS Buddy by destroyfx:
Destroy FX Extras [handies & stupids]

comes in both VST and AU, and provides detailed running averages in number form. (since the last poster wanted an AU solution)
