MIXING & EFFECTS
Vocodex is the last word in vocoders, featuring advanced articulation envelopes, integrated Carrier synthesizer and
Soundgoodizer maximizer, vocoder envelope control and up to 100 variable-width multi-parameter vocoder bands. Vocodex - By your command!

Vocoding is the process of using the real-time frequency spectrum of one sound (Modulator) to modulate the frequency spectrum of another (Carrier). The vocoder engine consists of a series of bandpass filters
that allow through only those frequencies detected in the Modulator source. So, for example, when a human voice is used to modulate a synthesizer chord, it will sound like the synthesizer is talking, the classic
robot voice from many sci-fi movies.
The Mixer section controls Modulator and Carrier levels, input routing and provides controls for fine-tuning input/output signals. From left to right:
These controls adjust the dynamics of the per-band envelope follower. Note that individual band behavior can be modulated relative to these settings using the Modulation Mappings section (below). From left to right:
- HOLD - Hold time for the Modulation envelope follower, set by ear. In PEAK mode (see below) the HOLD setting sustains the peak band levels for a defined duration. In RMS mode the HOLD
setting changes the integration window length. In this way PEAK produces stepped volume envelope and RMS produces a smoothly changing volume envelope (most evident at the longest HOLD settings). CPU
load also increases with HOLD length for PEAK, but not RMS.
- PEAK/RMS - Select the modulation envelope follower mode to PEAK or
RMS. RMS may sound better with some Modulators, so it's worth checking as it also presents a lower CPU load.
- Freeze (snowflake) - Press this switch to hold the current band levels. This is a good automation target for cool effects.
- ATT - Band attack time. Faster times (rotate left) will more closely track the Modulator volume envelope.
- Attack curve - Knob below ATT, fine-tune the band attack envelope curve. Labels show curve shape range.
- REL - Band release time. Longer times (rotate right) will make the sound more 'laggy' and reverberant.
- Release curve - Knob below REL, fine-tune the band release envelope curve. Labels show curve shape range.
- MIN TIMES - Ensures bands remain open for a minimum duration (minimum HOLD length). This reduces audible glitching.
These controls adjust the number of vocoding bands, their width and input filtering. While technical descriptions are given for each control, we recommend you 'tweak and seek' your desired sound.
- ORDER - Detection band filter order (1,2,3,4). Lower setting (1) has a lower slope to the input window edges while higher settings (4) have a steeper slope to the input window edges. In other words,
the filter order adjusts the roll-off in sensitivity either side of the central detection frequency. The default setting (2) is usually good, when adjusting by ear, sounds good, is good!
- Bands - Select from 5 to 100 vocoder bands (click on the control and move up/down). Each band is a slice of the Carrier frequency spectrum under the control of the Modulator signal. However, more is
not necessarily better or the sound you are after. Many 'classic' vocoder effects from the past use 8-16 bands.
NOTE: More bands also means more CPU usage. Vocodex uses a precise detection system, so it is possible to achieve great results with few bands.
- Band width (sideways arrows) - Adjusts the width of the vocoder bands. When a modulator sound is active, adjusting this knob will change their apparent width of the bands display. Set by ear, not by sight.
- Filter flatness - Controls if the bands have pointy (rotate left) or flat (rotate right) peak. This will affect the relative distribution of frequencies within each band. Another control to set by ear, tweak and smile.
- Modulator bandwidth multiplier (mouth) - Sets the bandwidth of the Modulator detection filters. Lower settings (rotate left) produce a more resonant sound, while higher settings
(rotate right) produce a softer more 'breathy/raspy' sound.
- Modulator pitch shift (gender symbols) - Slew the pitch of the vocoder down for a more masculine sound (rotate left) or up for a more feminine sound (rotate right).
- Modulator unison shift (people) - Control the pitch shift between unison voices. NOTE: The Modulation unison order must show a number for this control to be active.
- Modulator unison panning (speakers) - Control the unison voice panning. No panning is the 12'Oclock position, max panning happens at max left/right rotation. Direction changes voice panning mode.
- Modulation unison order (number display) - Off when set to ' - '. On - '1' to '5' voices. Unison is similar to a 'Chorus' effect where voices (copies) of the output are detuned and panned.
Warning: CPU usage scales with order (voice) number.
NOTE: Per-band adjustments to the above controls can be made using the Envelope section, see below.
Displays the vocoder bands, peak-level curve and Mapping Envelopes for the Modulator sound input.
- Follows Modulator pitch shift (lips) - Per Mapping Envelope switch, links the Mapping Envelope frequency-scale to the Modulator pitch-shift knob. When selected - the frequencies affected by the
Mapping Envelope will follow their original target frequencies in the Modulator as the pitch-shift knob is adjusted. When deselected - the Mapping Envelope remains at the original fixed frequencies while
the Modulator pitch moves relative to it (as the Modulator pitch-shift knob is tweaked). It is useful to enable 'Follows Modulator pitch shift' when a particular frequency/sound in it has been identified for modification
with the Mapping Envelope. Leaving this off will save some CPU load.
- Options menu - Opens to show standard envelope options including:
- Open state file / Save state file - Opens/saves envelope states. Opens a directory containing a number of pre-defined Envelope state files. Files are labeled according to the control they are intended
- Copy state / Paste state - Use this to copy and paste envelopes, usually between instances of the EQ editor across open plugins.
- Undo - Undoes the last envelope edit.
- Undo history - Shows the editing history since the last reset.
- Flip vertically - Inverts the current envelope.
- Scale levels - Opens the Scale Level tool.
- Normalize levels - Scales the envelope so the highest and/or lowest levels reach +/- 100%.
- Decimate points - Opens a simple tool that allows manipulation of the number of control points in the envelope (useful in conjunction with Analyze audio file).
- Filter - Opens the Envelope Filter tool (useful in conjunction with Analyze audio file).
- Smooth up - Opens the Smooth Up tool that allows smoothing of the envelope shape (useful in conjunction with Analyze audio file).
- Smooth up abrupt changes - Quick removal of 'spikey' or sudden changes in the envelope.
- Turn all points smooth - Preset filter to quickly filter the envelope.
- Create sequence - Opens the Envelope Sequencer tool. While this feature is common to all native FL Studio envelopes, it has been included as
it may be useful with creative uses of Vocodex.
- Analyze audio file - Open, analyze and replicate the volume envelope of an input sound file. Drag and drop audio files directly on the Envelope editor for automatic analysis. While this feature is common to all native FL Studio envelopes, it has been included as
it is particularly useful with creative uses of Vocodex.
- Freeze (snowflake) - Freeze all envelopes to afford a clearer view of the envelope/mapping. It's also useful to stop your little brother/sister/kids messing with your carefully crafted shapes (or you).
- Step editing - Sprays control points like drive-by machine-gun fire, allowing you to draw envelope curves.
- Slide remaining points - When selected, slides all control points after the moved point.
