[linux-audio-user] LADSPA Bandpass Plugin

I have been trying to create a test CD to use for tuning a PA system in a large auditorium, and I need a pink noise generator and a band pass filter to create "test tones" at each one of the frequencies on the eq. I am running DeMuDi, and using ardour as a recorder. I have a myriad of LADSPA plugins including a pink noise generator, but I cannot find a simple bandpass filter that allows me to dial in the precise frequency and the bandwidth. I have tried the TAP plugs, the CMT plugs, and the SWH plugs, and as far as I can tell none have exactly what I need. If anyone can help me or knows where to find what I am looking for, that would be great. ~Jeff
