becoming more or less “brilliant”, more or less “dampened”.
This is the type of filtering that you will find more often than not on synthesizers that use
subtractive synthesis. It can be found on most of the recent analog and digital
Spectrum of a noise signal proceed with a low-pass filter
The high-pass (high-pass filter or HPF), as opposed to the low-pass,
eliminates low frequencies and only allows high frequencies past. The sound will thus
become “thinner”. It is very useful for removing redundant low frequencies.
The band-pass (band-pass filter or BPF) eliminates the frequencies situated
on either side of the cut-off frequency. Use it to make a certain band of frequencies
that you wish to emphasize appear. This will make the sound more “pinched”.
