at this time, we're looking for practical patches, solutions etc. for the following methods:

search-tone method, Frequenzsuchtonverfahren, Oktavsieboszillograph, Tonfrequenzspektrometer we don't prefer the look of spectrograph~ but we need the result as described at p.239 in the schematic by the attached file

these patches should be possible to work in realtime (analyzing of incoming soundfiles etc.)

thanks
