1. e Once you have found the offending frequency bring the gain down to a Significant negative value 4 4 Compander The term Compander is a hybrid of Compressor and Expander First the signal enters the downwards expander which has a fixed ratio of 1 5 1 and is designed to reduce room ambience spill or breath noise that is often brought up by the subsequent compression The Thresh threshold ranges from odB FS down to 96dB FS which essentially turns the expander off The compressor offers both hard and soft knee modes alongside fully variable Ratio Thresh threshold Attack Releas release and Makeup controls The output stage which is sourced after the make up gain features an optional Drive feature This introduces non linear characteristics and hence harmonics to the signal and its intensity is controlled by the level of the make up gain knob More make up gain increases the level into the drive circuitry If you use a lot of make up gain to drive the circuit the level can be reduced again by using the Output slider 4 5 Process Order The four processing blocks can be arranged in any serial order using the process order controls at the bottom of the plug in To use just highlight the block you would like to move and press either the left hand arrow or the right hand arrow to move it one place in that direction 5 Graphical Displays Vocalstrip features an assignable display in the top right hand corner of the plug2.

7. ic history meter allows you to see at a glance how the amplitude has been changing over the past second or so A 30dB range from odB FS downwards gives ample information about the amplitude of the signal Peak Meter and Clip Indicator The wide meter bar to the left is a responsive peak meter which allows you to observe the exact input level at any point in time A red clip light at the top of the meters indicates that three consecutive samples are at maximum which is taken to mean that the input is higher than odB FS and is therefore clipping It will stay illuminated for 1 second following clip detection after which it will automatically clear It can also be cleared at any point with a mouse Click Dynamic History Meter The thin white bracket on the far right of the meter gives an indication of the recent dynamic range of a signal The top of the bracket measures the most recent peak level of the signal where as the bottom of the line shows the Smallest peak to have happened recently If the bracket is long it indicates that the signal has a large swing in dynamic range and if it is short the range is small If the top and bottom points of the bracket are quickly moving around it can be assumed that the dynamic range is quickly changing which could be interpreted as an energetic signal RMS Meter The thinner bar to the right of this shows the RMS average level This is useful in graphically judging the loudness of the sig
