Effective audio tools

[Donald Harvey]

I was wondering if someone can give me some effective audio tools in a bare Adobe Premiere Pro 2.0, and when i mean bare, no plugins. I dont have the money or time to use plugins right now, even though that would most likely be the best route, however, can someone give me some good effect audio tools to help out problems with shotgun noise or anything that will make it look more professional!

Thank you so much!

When you say, 'shot gun' noise, does that mean a weapon... or a mic... or how the 'noise' appears on a wave form...???

A shot gun mic. There is a lot of "hum" underneath the actors. The boom was too far away and we have no other takes, so the only thing to do now is try and eliminate as much of that unneeded noise as human/technologically possible. Help me please. Thanks.

Check out Audacity; it's free.

As I've said else where audio is not something that I know a lot about... how ever... I do know about Digital Signal Processing, and I understand a lot of the principles but audio people seem to use a specific terminology, that I'm not up to speed on...

But if the 'hum' is a low frequency hum, then one of two types of filters come to mind, a high pass filter which can be adjusted so that the 'voice' signal is mostly retained, but the 'hum' (say 60 cycle, refrigerator, air conditioner), may be reduced to the point that it no longer is interfering with the voices.

Another type of filter is a is a 'notch' filter which when tuned will remove a narrower band of audio, so that if you do need to retain some low frequency audio you can perhaps eliminate the offending 'hum'.

Audio people use terms like 'low shelf', 'high shelf' to indicate different types of filters...

Another 'trick' is if you can get the hum down, but yeah, you can still hear it... use another 'noise' source, to cover the objectionable constant 'hum'. Humans do note when there is no background noise at all... and the audio sounds 'wyrd'... so by adding some 'nice' room tone back into the audio track, with your talent voice levels up good enough, you may be able to 'cover' the objectionable repetive hum sound with some noise that will give the result a 'natural' feel.

you can apply a noise gate if your wanted audio is at reasonable levels above the hum. use a soft clip so that your audio doesnt cut in and out fro the gate too harshly. you could also process the audio within audition if you have it with the suite and just use the sampling noise removal and sample a section of the hum and remove it from all the tracks you need to. there are a bunch f ways to go about getting rid of hum.. first and foremost would be solving it while your on set and carefully monitoring your audio, but imho in post your best option would be a waveform sampling and removal as i described in audition. although a noise gate can be very quick and effective if your vocals are seperated from the hum by a good db percentage.
