The Placebo file thread got me thinking... Anybody want to write me a script? $10 reward for it...

[Viper GTS]

I want a script (or a compiled executable - even better - with source code) that will take three variables as input:

Time: In minutes and seconds
Starting frequency: In hz
Ending frequency: In hz

The output is a *.wav file of length time, sweeping evenly from the starting frequency to the ending frequency.

For example, a 74 minute frequency sweep from 0 to 25,000 hz.

Is this even possible with a script? I think it would be something like:

Write header info
Write audio data
Write footer info

Anybody know if this can be done? Anybody have any pointers if I decide to try this myself?

I might be able to write you a basic dos app that uses the PCSpeaker, but no wav output.


I'll see if I can do it (been a while since I've programmed), no need for payment.


And I don't think this can be done with any script...

 

[Keego]

with the right library, I bet you could make a C script that does that...

 

[Viper GTS]

If you can figure out how to do it that way it might get me started on doing the WAV output... Or give someone else the help they need.

I specifically need/want wav output for the ability to make CD's with it.

80 minute sweep from 0 to 25,000 would be a lot of fun to have.

well, I just checked. I can't do it properly...sorry.

 

[Beau]

Working on it.

Why would you want it 80 minutes long?

Are the $10 US Dollars? I don't want to be ripped off like the last time and get Candian Dollars and only afford a can of RC Cola :|

<< Why would you want it 80 minutes long? >>



To fill an 80 minute CD, of course.

Oh, and peto, do you realize 30 IQ points is huge? An IQ score of 130 is considered average, while 160 is extremely intelligent(some might say genius starts here).

This would be cool to have.
Is it posted anywhere?

 

[pulse8]

Yes....post this

 

[Evadman]

Fine. since everyone wants it, go ahead.

Sweep / tone Generator

From ZD-net. It is a tone generator ( Use for phone fun! ) but will also output sweeps to a .wav file.

 

[Jerboy]

Agilent Technology makes a function generator that can do this sort of thing.

Hook it up to input and record it to wav

Nah, 100 is average, 130 is entry-genius (MENSA requires 132 i think), and 160 is extremely intelligent.
