Sound Forge White Noise mixing?

2004-06-01 01:31:49

I have an application that needs audio wav files to sound like they're coming out of a noisy radio. I though of just doing a batch where I mix every sample (over a thousand) with "filtered noise" which sounds rather nice but I can't figure out how to MIX that in for each sample. I can get it place before the sample or after the sample but not THROUGH the entire sample.

Anyone know how to pull off what I'm looking to do?

Probably better to use an eq (and maybe some delay/reverb) to acheive the effect you want.  Most eq's have a preset for radio or something similiar.  You can try the Waves 30 day trial.  There also some plugins out there to add a "static" or "hiss" to the signal to recreate vinyl or radio sounds.  A little distortion probably wouldn't hurt either.


If what you're going for is at all similiar to "Wish You Were Here", they acheived that sound by actually making a quick recording of the intro onto a cassette and then went out to the car and actually played it in the car while recording it. 

Sometimes the best way to approximate a sound is to get the genuine sound, ie, if you want it to sound like it's coming out of a noisy radio, play it on a noisy radio and record it.

I don't know if it's still available, but there used to be a Batch Converter free download from sonicfoundry before Sony bought soundforge.  If it's not still available, pm me.

Paste Special -> Mix    (iirc)

But, yeah, plugins could be a better idea..

Cakewalk has a plugin, Audio FX2, that includes a tape simulator. You can simulate tape hiss--this might not be the sound you're looking for, but at least it's noise, and it's in an easy-to-use plugin form. There's a demo available here.

If it's just a matter of mixing two waves together, SoX (sox.sf.net) will do what you want. You will need a white noise sample the same length as the target sample - you can easily generated that with only a few lines of C.

Well, this is for an air traffic control simulator so you've got cockpit noise, radio noise, etc.

I don't want to have to do any matching of lengths as that'd be a REAL pain. I just want to select a noise and have it loop through the sample from start to finish.

I also used to own the Batch Converter but assumed it was in the latest Sound Forge. I guess I'm wrong on that one.

If you're up for a challenge, you could take an acoustic impulse of the inside of a cockpit and then apply that to the sounds.  Search teh SoundForge help for "acoustic Impusle"
