Hi everyone

I'm just starting with pd and I have zero sound design experience. However, I would like to design the sound of someone blowing up a birthday balloon (no breathing, just the sound of the air filling up the balloon).

I've been unsuccessfully trying to tweak a hissing example I have (attached). The sound is exactly what I want, but I would like to have more control over the result, and maybe add an attack and decay?

Any tips or advices will be fully appreciated.

Thanks in advance.

Hey, welcome to this forum!
I'm a little curious.. why do you need a blowing-up-sound of a balloon, especially a birthday balloon, if I may ask..?!

To get some more dynamics, you could try to use [vcf~], with low Q. The filter-frequency could be controlled by the volume-signal (scaled of course).
To gain better control over the envelope (attack/ decay etc.) maybe build your own with a [line~]/ [vline~] (for the table-index) and a table/array (for the wind-volume), have a look at [tabread~]/[tabread4~].

I've just played/messed with your patch. It's basically a setup as described above. I didn't think one could get some relatively authentic sounds of wind that easily... ..wind in the trees, wind at a field, rough wind, tough wind, windy wind...

Hi, Flipp

This is for an animation I'm working on. I've managed to create other sounds, but struggling a bit with this one!

Thanks for your suggestions, I'll have a look at those settings. It is hard to figure out how to create recognizable sounds other than noise or abstractions

I always wonder if the sounds one creates are recognizable.. or if it just sounds familiar cause I know how they thould sound...
Don't you have a balloon and a mic?!...;)
