Hello,
is there any way to get near-realtime audio spectrum info faster than FFT ?
For example- VST graphic 7 band EQ,with level meters for each band..

Hi,

By Real-time, do you mean the delay or processing power? If it is the delay then a FFT would
delay as much as a band-pass filter depending on the FFT lenght. However, you can get more
relevant audio spectrum ( by spacing the bands frequencies in log seperation) using a band-pass
filter. 

Regards,
Amit

Hello,

Bandpass filters is the preferred approach.
