Hi All,

Im looking for a document/website or reference guide on Wave forms, specifically detailing what frequency represents a note.

For example 261.63Hz is a middle C and I think multiples of 44Hz (ie 44, 88, 132, 166 and so on) are F in different octaves (anyone jump in here I may be wrong!) But thats the only info I have, Im looking for a complete chart or list - or indeed any further info on this subject!!!

:cheese:
Cheers

A is 440Hz... you should be able to work out the rest from there.

Remember: Apollo 440. :D

Piece of piss.

Wrote a graphing calc program for this ages ago.

Take your frequency and then find out how long each cycle lasts (preferably in the C2-3 region) and multiply that time figure out until you reach between 200-400ms worth, this is your quater bar figure, then put that into this equation

60000/figure = tempo.

this will give you a tempo for an exact number of sinwave cycles in a quater bar...

At the given frequency...

137.655 = D

i had a massive list of the others, but i dont bother with it.

When I'm not banging out tracks I'm a Full-time Graphic Designer, so I made this Keyboard layout that has all the Frequencies, Midi # and Key Notes, I initially made this for a Digital Arts school in San Francisco. Any suggestion to it's refinements would be much appreciated :)
