well.. i know there is a soudn tutorial already made by hacker dan...but he didnt cover on how to use the frequencies...
well as you know the sound in turing is based on the frequency and duration lets look at the basics
for most pianos*especialy digital* are tuned to the frequency "440" this is the note "A" below middle C.....well thats usefull enough but how do u gte lets say "middle C"well..theres this simple formula you have to rember:-)
x-is the note we want to get
y-the note we know
z-semi tones between them
x= y*2^(z/12)
so lets try for c
x=440*2^(3/12)
x=440*2^(0.25)
x = 523*rounded*
now lets try this formula ot make a chromatic scale
| code: |
var x := 220 loop sound (x,500) x := round(x*2**(1/12)) end loop |
as you see everytime the loop is intiated the frequency goes up by one semitone...this cna be usefull to make keyboard type programs like the none in "turing sourcecode"...i made that one based on this formula
well i hope this helps
*ps*this is my first tutorial* show mercy and give advice
