Tip-toeing in from Vegas Video forum... Bass/Rumble

Jay Gladwell wrote on 5/6/2004, 1:47 PM
This may be a stupid question... I'm not a "sound" person, so you can take that into consideration.

On several sound effects, a jet fly over (5.1), for example, I would like to add more bass (rumble) that simple isn't there. Is there such a thing as a generic "bass/rumble" track that one can buy/download/obtain for adding bass to tracks that otherwise lack it? I think it's referred to as sweetening?

Thanks for your patience and help!

Not a stupid question...

This may be though.....

Are your monitors capable of reproducing the lo-freq you are wanting to hear?

If so....

Try opening the Jet Fly Over in sound forge:
1. Effects/Pitch/Shift
2. process file -12 semi tones (this is down an octave lower), Accuracy at maximum and check "Preserve Duration"

Make sure to click on "Save As" and rename the file so you don't overwrite the original file.

You can then timeline correct the edited file along side your original file and send it directly to the sub channel. You may want use a lo pass filter (EQ out everything above 500hZ) because they will be useless frequencies when sent only to the sub.

That should provide your track with plenty of low end (Vertigo & Nausea) which should leave viewers of your video running for the bathroom...

Yes, they can reproduce the low-end frequencies very well. I'll give that a shot, Todd, thanks!

Great J,

Let me know if that works ... I prefer using this method to bring in rumble effects when mixing in 5.1.

I'll sometimes render the entire audio portion and treat it this way and timeline correct it in.

The nice thing about using this method is; the low frequency will be the result of the original audio and won't sound canned.

You can automate it in and out as wanted, too....

Another Idea if that don't work, like you mentioned would be to add Sound FX's and mix them in. I have a large library of Sound FX's CD's and what I would do is look for an earthquake rumble sound FX and mix it in with your original Plane flyby sound. Lots of SFX libraries with actual earthquake rumble recordings. Sony is offering a new Sound FX library package, you might want to check that out. The majority of my Sound FX's come from Hollywood Edge, and Sound Ideas. Usually you buy these in set volumes, but maybe they can be purchased individually, or maybe you can find something for free with a little searching on the internet.

Todd, when I tried adjusting the EQ as you suggested (assuming I did it correctly) the dB got so loud as to make it clip! When I lowered the dB, the "rumble" was lost.

Brian, I did find a "rumble" at Sound Dogs, where you can buy individual FX . Thanks for the suggestion!

"(assuming I did it correctly) "

It sounds like you did it incorrectly. Todd said "Low Pass filter" which is the correct terminology, but this could be a little confusing using the Sony Track EQ.

Do this:
Open the Sony Track EQ. Select Preset "Default all parameters".
Select Dot #4, which is a "high Shelf". If you boast the gain, it's really a "high shelf", if you reduce the gain it becomes a "Low Pass filter". Anyways, set the frequency of Dot #4 to 150Hz, and set the gain to "-inf", now you have a Low-Pass filter, and you won't get any clipping like you, where. Now adjust the track fader to mix that in. If you want more of the high frequencies, raise the frequency fader, if you find you're getting too much higher frequencies, then lower the frequency fader. The majority of the rumble sound you're looking for is around 80 Hz and lower.

Thanks, Brian, I'll give that a try tomorrow. Right now, I've got a head ache, and need to give it and me a rest. I'll let you know how it turns out.

Brian, you've just proven once again that knowing what you're doing makes all the difference in the world.

In video/film, sound is equally as important as the picture, in most people's mind, anyway. Which brings me to the question, where does, can, should, a person go to gain an understanding of all the ins and outs of sound? I see all these really great audio tools in Vegas, but I have little or no idea how to properly apply them!

Thanks again for your help, all of you!

I got most of my recording training through the Recording Institute of Detroit. I later became an instructor there and taught classes for 5 years. This school was started by Bob Dennis. He was a mastering/mixing engineer for Motown in their Hay day. I can owe most of my recording knowledge to Bob. Since the time, I've left the school Bob has expanded the school to online training courses. I haven't been through his online training, although he has asked me to go through some of his mastering study guides, but I can tell you if Bob wrote it, there's a lot that can be learned.

There are two or three "low end rumbles" on the free 1001 Sound Effects CD. It used to be downloadable ... I'll see if I can dig up the link. Or does anyone remember what the link was?
