I don't know how far you've got into Metro but you could do this.
I'll give you a quick run through of using a plug in.
- get your audio into metro and lets say its on track 1.
- go to the windows menu and open the "plugins" and "effects/synths" windows (Command 9 & Zero)
The top of the effects/synth window displays the track number and its name. (make sure this matches with the one you want to modify....track1 for now).
- go to the plugins window and drag Apple's AUGraphicEQ into the effects/synths window
- clicking on its edit button in the effects/synths window brings up a window in which you can change settings for this plugin.
- play your audio track and make adjustments and you'll hear the changes.
The cool thing is when you remove the plugin the audio returns to normal and is unaffected..........or you could decide to leave it their, or to save CPU power, record the changes onto another audio track.
This was just a quick demo and not the plug in you were after, but I just wanted to show a plugin that can make a big change quickly.
For gain - my suggestion is go to
http://www.digitalfishphones.com/
enter the site and click on the audio plugins. Go to the fish fillets and download the free plugins. They do de-essing, compressing and limiting. You can't go wrong.
Another thing to try is going to the plugins window and grabbing the AUMatrixReverb. It can add nice touches.....even with the plate or small room. If you like this kind of thing, go to
http://www.silverspike.com/Download/download.html and download RoomMachine 844.
Now you've got a busy weekend.
have fun
