Hi Winy.
How good is your ear when it comes to naming musical notes? That
can help a lot.
If you can name some notes by ear, you can learn the frequency
values of those notes.
Fourth octave A has a frequency of 440 Hz. Hz (Hurtz) just means
vibrations per second. If you double the frequency, your sound
will be an octave higher. So, 5th octave A is 880 HZ, 6th octave A
is 1760 HZ. Going the other way, you cut the frequency in half for
each octave you move down. 3rd octave A is 220 HZ, 2nd octave A is
110 HZ, 1st octave A is 55 HZ, and the A at the bottom of the piano
keyboard is 27.5 HZ.
Experimenting with the keyboard a little can tell you that bass is
down say 200 HZ and below. Midrange is near the middle of the
keyboard, and high frequency sounds like symbols, the S sounds of
someone speaking or singing, or the brilliance of an acoustic
guitar are up pretty high, 5,000, 10,000 etc.
You need to take an equalizer band, turn its gain up fairly high so
you can really hear where it is boosting, and then adjust the
frequency slider for that band up and down. Listen to how the sound
is changing as you sweep the frequency way up, and way back down again.
