1. Introduction Thank you for purchasing the Vocalstrip plug-in for the SSL Duende platform. Vocalstrip is a one stop solution for superior vocal processing, with all the tools you need to take your vocal sound into the big league. Vocalstrip features 4 configurable processing blocks to take care of unwanted artefacts, dynamics and equalisation and extensive metering and visual feedback give you invaluable information during your work. Liberated from any analogue style control legacy, the Vocals

Hardware Limitations Because of the many processor-intensive processes that are part of Vocalstrip, this plug-in uses a large number of Duende DSP cycles. Although this is un-noticeable for most ‘normal’ use, it does mean that if 6 or more Vocalstrips are loaded onto one Duende DSP at 44.1/48kHz and all of the modules are enabled (ie De-esser, De-ploser etc.), then a 7th will not have time to be processed. This will result in the audio ‘crackling’ or glitching. To minimise this situation we have

3. Installation & Authorisation A time limited trial version of Vocalstrip will be installed during the Duende v2.6 software update. This allows Vocalstrip to be run in evaluation mode, which means the plug-in can be used with full functionality until a certain number of samples of audio have been processed. At 48kHz this gives 10 hours of continuous use for either stereo or mono plug- ins. At the point where 10 minutes of the evaluation period remains, the countdown timer will turn red. Once th

4. Vocalstrip In Detail 4.1 De-esser Sibilance is a resonance often found in vocal recordings which can cause undesirable distortion artefacts which sounds like the ‘S’ constants are overly high in level. The De-esser in Vocalstrip intelligently detects these sounds and gives you control over how much attenuation to apply. The blue indicator between the controls ‘glows’ to show that the de-esser is working. The Thresh (threshold) control sets the relative detection point, so that the de-esser ca

4.3 Equaliser Three popular EQ types are provided to allow you to cut low frequencies, find and attenuate resonances and shape the top end of the signal. Each EQ type features independent in/out switching: • The low cut filter operates in the range of 30Hz to 300Hz – you will see from the graphical EQ display that it causes a slight boost around its cut- off frequency. • The notch filter operates in the range 200Hz to 10kHz and offers 12dB of boost and 36dB of attenuation. It has a high Q 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 0dB 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 (releas

5. Graphical Displays Vocalstrip features an assignable display in the top right hand corner of the plug-in GUI. This toggles between showing the Compander Law Graph and the EQ response curve. Clicking on any of the controls in either the Compander or EQ section will switch to the appropriate display. When displaying the EQ response there is also the option to show a real-time FFT analyser engine reports the amplitude of all frequencies at any moment in time. The analyser can be placed at either

5.3 Compander Law Display This shows the output level for any given input level according to the Compander controls which are currently being used. You can see both the compressor and expander threshold, indicated by the two knees. As the ratio of the compressor is increased, you can see the top portion flatten out indicating that the output level for any given input is being reduced. 5.4 I/O Difference Display Also known as an amplitude histogram, the I/O Diff meter shows the relative occurrenc

5.5 Meters The Vocalstrip input and output meter displays are, in fact, three meters in one. They offer various ways to easily read the Peak and RMS levels of a signal over time, and the ‘dynamic 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 0dB 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

6. Control Options Move the mouse cursor either up/down or in a circular movement over a knob to adjust its parameter value. The exact nature of the movement you need to make to change a knob value is dictated by your DAW. • The scroll wheel can also be used to alter parameter values here • Press whilst scrolling for increased resolution • Press & click (Windows) or ⌘ & click (Macintosh) on a knob to reset it to its default value • Exact numerical entry is possible by double click

Clicking the Load button with the left mouse button will bring up a standard Macintosh OS X or Windows dialogue box asking you to choose a file to load. The Save button behaves in the same manner, and when clicked will ask you choose a destination to store the file. It is suggested that Vocalstrip presets are stored in an SSL Presets directory created on one of your hard disks. Alternatively, you may wish to store the presets in a sub-directory within your project folder. 6.2 A/B Functionality A
