View Full Version : Hi and Lo Pass Audio Filters

11-23-2012, 05:07 PM
Joe discusses the filters and uses values in his demo in order to filter out certain sounds on the audio display. How do we determine the best values to enter in order to produce a proper audio display to ease sequencing? I tried the values used in the demo. I am not familiar with Lo and Hi pass filters. Can anyone provide some values or guidance so we can better utilize this feature? Thank you!

If you could envisage a piano keyboard then you could establish some idea.
A lowpass passes all the notes equally up to a certain key. From there on you get a diminishing return.
A highpass passes all the notes equally from a certain key and upwards but a diminishing return below that certain key.

So it's up to you to determine which notes you want to pass and which notes you want to reject with diminishing return.
There is no right answer, but rather what effect you want to achieve.
