know of a good noise filter?

Post by Rat-Sass » Tue Sep 07, 2004 10:33 am

Currently, to filter noise, I go into edit mode on MTStudio, and delete all sound data between signals; then I fade in/out to smooth it over. This works well for the most part.

However, back in the day (when I used QBase) I could sample a specific sound on a track, and eliminate that sound throughout the track (ie: amp hum, etc).

Any suggestions for doing that in MTStudio? Procedure, plugins?

The best approach I've found is to eliminate noise before it's recorded or at least reduce it to an acceptable level. Noise gates and isolation set-ups work well for me. So far, I've been lucky with hum problems, but have heard for those not so lucky, that the Ebtech Hum Eliminator works well.

Sometimes when I'm working with an online collaboration, I'll get tracks that are a bit noisy - in that case I'll use the GoldWave editor for noise editing. It has the feature you are talking about - sampling a specific sound to remove throughout a track. If you can find the free copy of CoolEdit96, it also has this feature. What I've found though in using this feature, is that it also removes sounds I'd like to keep. :?

The addage - "an ounce of prevention is worth a pound of cure" is very true here. :)

There are four ways I can think of to reduce noise using MultitrackStudio:
  • 1. Record the track without noise :wink:
  • 2. Use the Noisegate effect. This one only works if there are 'silent' parts.
  • 3. Use the Dynamics effect (set up to works as expander only) to make the soft parts even softer. This can work on tracks without silent parts.
  • 4. Use a Band Effect, set the number of bands to two and the crossover frequency at approx. 2 kHz. Load a Dynamics effect in the treble band and set it up to work as expander. Now play the track and watch the Dynamics effect's display: the 'gate' is supposed to be open during loud treble parts. This one processes the treble frequencies only (that's where most of the noise is, but only a little bit of the music). DNL (Dynamic Noise Limiting), as found on older cassette decks, works like this.
If you prefer to do it manually, it may be easier to use an Automated Fader effect rather than to delete parts of the track.
