Yahoo Tuning Groups Ultimate Backup tuning Precise and simple frequency analysis program required for mac

Are you planning to make observations. i.e. by

a) recording each bell and processing the audio to reveal the spectrum, or

b) is this to be just a theoretical (calculated) exercise?

If a) I suggest Spear or a more sophisticated Spectrum analysis application. I'll see what el-cheapo FFT application are available (maybe Audacity will do it). If this is what you need, I shall need to do some more research to find the most appropriate method.

if b) FileMaker is probably the most convenient - I you give me the equations, I can write a FileMaker Solution to do all the calculations.

JK likes the new place and is settling in well.

Dear List members,

I have been advice to use Matematica to get a list of the spectrum components of the bells I am analyzing

I have used Spear which is great to provide the graphs and to experiment altering the components in a visual way, but I do have to provide the tables of component values with at least one decimal for Hz values and I would like something accurate or at the least assistance to use Matematica if someone confident has a spare minute.

I am doing this for 150 conic bells, 500 japanese temple bells and 20 chinese opera gongs, so it is a very straight forward process of opening the sound samples one by one and getting the values, unless someone can program a routine for Matematica to do a whole bunch, in which case I am happy to pay for it.

Thanks Charles for suggesting programming FileMaker for the modeling of an ideal bell. At the moment the conic bells are sounding just perfect to me with a strong minor third component ( around 1507 c) and a stretched octave of around 2470 cents which sounds flat (and obscure) when adjusted to 2400 c. There is a lot of work involved on creating a solid steel mandrel, so the 2 mm steel sheet can be spun on a lathe in several stages (to get thickness even all across the bell). I would also imagine that whatever I can simulate with 'Spear' to change the components of the spectrum so I can get a more attractive tone, it might not be that attractive when the a bell designed to favour those partials is created. I would imagine some partials are related and you cannot simply change the shape of the bell to favour on single partial but a combination of them.

I know the people doing the Australian bell have done a lot of work on this but they have the bugs to cast, test, cast, test ... oh well I guess I could practice casting my japanese temple bells! haha!

Any help would be really appreciated!

Sincerely

Tony Salinas
