Sound Generator

[Ham]

Hi,
I am trying to do some experiments with sound generator. I have tried to change the frequency and wave form of the generated sound without success. I can hear a sound is generated but how can I control its frequency and wave form?


Best Regards

Hi,

When you change the wave type or so, you have to re-generate the sound. Then, add the sound to the MMF bank.

E.g.

Set wave type to 2
Generate sound
Add sound as "Hello"

Then use the Sound Player object to play "Hello".

EDIT: You just added a file..... do not generate before changing the wave type :P

Thanks Looki,

I will give it a try now.

Is this object fixed now? Last time i checked it wouldn't even show in the object list anymore, well the flash versions anyway.

Hi Looki,
I did as you mentioned. I can change the wave form without any problem. But still I cannot change the Frequency. In fact it generates a sound even if I do not mention the frequency which I suppose it is the default frequency being used. If I try to change the frequency before I generate the sound, no sound is generated and if I do it after the sound is generated it does not change the frequency of the sound.

Yes you are right I had the same problem. But it is ok now.

Ham I can't test it right now because I don't have any sound output here... maybe later! I'll get back to you.

Oops, I know the problem now. You use extremely high values!
The variables accept values around 1. The default frequency is 0.3. You can get all the values via expressions if you need guidance. Also, you can enumerate them and output name+value for a quick overview. Sorry for that, needs better documentation+examples!

Thank you Looki for the explenation. I can change the frequency now. But as I understand this is a factor which is being multiplied by another to generate a frequency which can be heard. What frequency is generated if the factor is 1?

I honestly didn't know because I simply implemented the source code of sfxr.

Now that I looked at the code (which is a bit messy and there are no comments), it seems to be quite complex. I can't make any sense out of it. It would probably be easier to use a program like Audacity to measure it.
