Vocoder in Audacity is Clipping

I'm using the plug-in vocoder for audacity for my robot vocals. However, the effect really lowers the volume. When I increase it to make it fit in with the rest of the project, the clipping ruins the effect. I've all sorts of sound effects on the timeline all different volumes...mostly loud. The vocoder effect is very soft so it's hard to mix. I've used the normalizing and leveler effects to try to smooth them all out no avail. My goal is to burn an audio cd for use in the performing arts. But I've a sneaking suspicion the authoring software is going to sample my loud music tracks thusly throwing off the vocoder tracks even more.
How can  I remedy these problems?
Thx

Hi zoobie,
I'm not fam,iliar with this plug-in vocoder
but being a big user with Audacity, I have found that using wavs if this is the case, I had to reduce the wave volume on the master volume on my taskbar first
otherwise the wav distort.
Open Audacity and drop on your files you want to use,
reduce the wave first but don't close your master volume control incase it changes it.
Then increase the recording volume and master volumes test it first, play the files then clicking on the small mic below the recording graph, note the red bars.

What format is these vocoder?

The vocoder comes with the latest Audacity and a plug-in with earlier versions. The vocoder is an effect on my voice saved as a wav. I'm trying to get the volumes acceptable before I burn a cd for a performing arts project. I've enclosed an image where you can see the huge differences in volumes on import. You can also see my taskbar volume is pretty low. The top graph is the voice/vocoder and the bottom some music. Working with voice-overs (VO's), you probably already know that the voice has to quite louder than the music. The same principle applys here (I think) where they should at least be equal volumes. So you suggest to turn down the music wav volume on the timeline instead of amplifying the voice/vocoder effect and recording to test the levels? I thought what you hear is what you get...Thanks

Hi zoobie,
ok I see.. Recording different sessions of your voice talking then doing voice over music.
I take it these are separate pieces
What I would try..
play your music in winamp or media player and re-record it in audacity but reduce the recording volume then save as mp3. This will lower the volume of the music.
Then drop the new mp3 on and your voice tracks

Another workaround AutoDuck a bit time consuming but once you have it setup works good..
Auto Duck reduces (ducks) the volume of one or more tracks whenever the volume of a specified "control track" reaches a particular threshold level.

They're not really VO's rather butted up against each other. So you think re-recording the song at a lower level and saving as mp3 is better than just turning down the songs volume on the timeline? I've about 200 sound effects all different volumes on the timeline again not overlayed but butted up against each other.
Thx

Yes what you hear is what you get so if you're happy with that go for it.
200 sound effects wow good effort pray you dont close audacity,
what do you have a bunch of wavs and want to join them? and add over a music track?
On that note it's probably quicker to re-record just the music side but less volume in Audacity
volumise them so that it levels out with the wavs
Your basically mixing a track are you?
What other tools do you have?
nero 7? Nero has a nero wave editor
also good stuff in Nero vision for mixing audio with a video if needed.
Acoustic mp3 is a great tool for mixing a track

I'll give you a funny tool if you want to play with voices had to rename it to upload it, so just add .exe to it,
 free funny text to speech tool the kids use for fun, type in some words and select a voice

How do you record the talk machine with Audacity? It's coming out my speakers but is not being recorded.
I'll have to fiddle with the rest on a cd-rw

Thanks
PS - I just noticed still more volume settings on this thing.
