You could also analyse the spectrum of a sample to see what is going on and try to replicate that...

Thanks Matti, the filter sweeping approach is something that sounds like it might work. At least one can hear that kind of thing happening in the sound. I don't want to use a sample as ultimately I want to be able to tweak parameters to give each punch a unique sound.

However, note also that for some of the more realistic punches (like in the video) you may actually need recorded audio (e.g. punching a piece of meat or leather).

I’ve had some success previously by layering noise that has been filter swept in different ways.

I.e. have multiple noise samples (e.g. pure white noise) and then perform different filter envelope on them so that they blend together to form a full punch sound. Additionally you may want to focus on two separate sounds, the transient (the main hit) and the tail. You might want to try distorting some of the noises as well to get that “in your face” effect.

I'm trying to create a punching sound for a computer game. While it's not tricky to get something that would toe the line in an 80's video game(see below), I can't quite get that punchy sound I'm after. Something like this would be fine:

Any ideas? I thought opening the bandwidth of my filter over the duration of the sound might work, but it doesn't seem to help.

Don't know if this helps but maybe you can do an analysis on the
"whip" sound as well, the punch sound just sounds like a whip sound
with a bass drum added to it to me.
