 Bass
Frequencies and Note Conversion

Tips for creating original and fat bass sounds with harmonics,
starting with ordinary samples and waveforms.
The reason they are called harmonics is that they are usually
HARMONIOUS with each other. Lets say you sampled some insane noises,
stacked, resonant filtered, and enveloped to get some interesting
mid/upper harmonics then added the result to a sine wave at 80 hz
(cause my dumb ass told you to). Then you carefully lowered the volume
of, or low-pass filtered, the mid/uppers so that they sound natural
with the bass frequency and perhaps enveloped the whole thing to make
"one sound". The result sounds good, but it makes you cringe
a little - like it's "off key" or something. Some of you
maybe got some real kick-ass "dark" sounds this way and think
im a freekin genius, while maybe some of you didn't tweak and tune (and
work hard) enough and said "this guys a jerk". Keep in mind
my original post talked about using a wave at ABOUT 80, and I mentioned
that you must experiment to get results that sound good (sorry but
giving you an EASY, EXACT formula for a NEW AND ORIGINAL BASS would be
a contradiction- think about it) . In any case those "off
key" results come from the bass frequency being "out of
harmony" with the uppers. Fine tuning the frequencies is the key
(bad pun?). This table might be a useful tool for those who already
have an ear for pitch, and may be a starting point for self-taught
punks like me that are starting to develop actual musical knowledge
from all this sampling nonsense....
