EQ Envelope

I want to use an EQ to remove things like hissing sounds, lip pops, etc. But I may not want to do it for the entire vocal section. I would like to use the EQ Envelope in Cakewalk 8.3. But after turning on the "Enable Band" and then adding several other bands I could not hear any difference in voice levels. How can I use the EQ Envelopes to alter a sound? I have tried adding nodes and making triangles, etc. I also have used the volume and gain envelopes extensively. But with the EQ Envelope I can not determine difference in the voice levels. See image bellow.

    I'm not to clear on what your doing I see a Lo pass filter, you won't really her much from that. 
     
    What you can do is first clone the track to keep a safety copy. 
     
    Then highlight the offending section and open the EQ plug and "render"  that section. 
     
    If you have a wave editing program like Wave Lab you can also tool copy the track into it and do some fine tuning, that's what I do. I find using Sonar to do wave editing kinda slow and clunky.

    Your screenshot shows a low shelf at 79.7Hz. This would have very little effect on a vocal track except to remove rumble.
     
    What you have to do is first determine the frequency range of the artifact you'd like to reduce, and then select a band-pass filter set to that frequency and just wide enough to reduce its volume. You can use SONAR's Analyst plugin for that, or download the free Voxengo SPAN plugin, which works better. Start by setting a high gain increase and sweep the center frequency until the artifact is made excruciatingly nasty, then use automation to reduce the gain.


    All else is in doubt, so this is the truth I cling to.

    I tried the mid and high tenor bands and still could not hear any difference.

    Try inserting an instance of the Sonitus EQ into the fx bin and automate that instead. That way you'll be able to visually observe the EQ curve change with the automation and thus verify that you're really automating what you think you're automating.

    Yup, I have Sonitus EQ and I have been able to make some nice changes to my voice mid and high levels. A lot of the Mic Static is gone and it sounds nice. But the lip clicks and hissing is still there. Do you know what frequency hiss and lip clicking sounds usually range in.

    Remove lip smacks and mouth noise with a automated volume envelope. Just add a envelope, find the offending noises and pull the level down at that location by adding nodes.  It is really easy and a big part of the engineer's job. As far as hiss, if it's only during quiet passages, ie; when no vocal is present, snip the track to clean that up.
    If you don't want to spend the time cleaning up the track by snipping, you could try a gate on the track if the hiss is only apparent during quiet sections. If the hiss is on top of the vocal, you'll just have to find the frequency and pull it out with the Sonitus eq. start at around 7-8 k. 

    Best,

    As Danny noted, lip smacks have to be mitigated via editing and/or dynamics control, as they cannot be efficiently removed with EQ. To apply enough filtering to make them effectively disappear, you'd have to seriously dull the track to the point where it wouldn't sound good at all.
     
    Vocal track preparation usually does entail a lot of tedious detail work. Like Danny says, it's a big part of why an engineer earns his pay.
