Aetherial TX Voice Processor / Aetherial RX Poodoo™ overview¶

The Aetherial Poodoo applet is the harmonic-enhancement stage at the centre of the Aetherial Audio chain. It runs as two fully independent instances — one on the TX path ("Aetherial TX Voice Processor") and one on the RX path ("Aetherial RX Poodoo™") — letting you shape low-end weight and high-frequency air separately for transmit and receive audio.

Before you start¶

The PUDU stage must be enabled in the CHAIN widget on the matching TX or RX side before the applet is visible.
The Aetherial Audio (TXDSP) parent container must be open in the applet panel.

How it works¶

Each Poodoo instance processes audio in two parallel bands, referred to as Poo (low-frequency) and Doo (high-frequency). The character of the processing is set by the mode you choose:

Even mode uses Aphex-lineage asymmetric shaping — predominantly even harmonics, warmer in character, with Big Bottom low-frequency saturation.
Odd mode uses Behringer-lineage symmetric tanh shaping — pure odd harmonics, brighter in character, with a feed-forward bass compressor.

Both bands produce a wet signal that is blended back with the dry signal using their respective Mix knobs. The animated PooDoo logo pulses with the brightness of the processed (wet) signal RMS, giving a visual indication of how much enhancement is active.

The TX and RX instances are opened by double-clicking the PUDU stage in the CHAIN widget on the corresponding side. The floating editor is titled "Aetherial Poodoo™ — TX" or "Aetherial Poodoo™ — RX". You can also right-click the "Aetherial TX Poodoo" or "Aetherial RX Poodoo" sub-container titlebar to float, pop out, or hide it. Bypass is handled from the CHAIN widget directly; there is no separate Enable button inside the applet. When the stage is bypassed, the entire applet tile dims to reduced opacity to indicate that DSP is inactive.

All settings are persisted independently for the TX and RX sides.

What each control does¶

Body group (low-frequency processor)¶

The three knobs under the Body group label shape the low end.

Control	Default	Range	Behavior	TX setting key	RX setting key
Drive	6.0 dB	0.0 – 24.0 dB	Drives the low-frequency saturator or compressor harder. Linear mapping. Displays as "X.X dB".	`ClientPuduTxPooDriveDb`	`ClientPuduRxPooDriveDb`
Tune	100 Hz	50 – 160 Hz	Centres the low-frequency focus band. Linear mapping. Displays as "X Hz".	`ClientPuduTxPooTuneHz`	`ClientPuduRxPooTuneHz`
Mix	30 %	0 – 100 %	Blends the enhanced low band back with the dry signal. Linear mapping. Displayed as percentage.	`ClientPuduTxPooMix`	`ClientPuduRxPooMix`

Clarity group (high-frequency processor)¶

The three knobs under the Clarity group label add presence and air.

Control	Default	Range	Behavior	TX setting key	RX setting key
Tune	5000 Hz	1000 – 10000 Hz	Centres the high-frequency excitement band. Logarithmic mapping (1000 * 10^n). Displays as "5.0 kHz" above 1 kHz, "X Hz" below.	`ClientPuduTxDooTuneHz`	`ClientPuduRxDooTuneHz`
Air	6.0 dB	0.0 – 24.0 dB	Amount of harmonics and air added at the high band. Linear mapping. Displays as "X.X dB".	`ClientPuduTxDooHarmonicsDb`	`ClientPuduRxDooHarmonicsDb`
Mix	30 %	0 – 100 %	Blends the excited highs back with the dry signal. Linear mapping. Displayed as percentage.	`ClientPuduTxDooMix`	`ClientPuduRxDooMix`

Mode¶

Control	Behavior	Persisted setting
Even	Selects Aphex-lineage asymmetric shaping. Lit amber PooDoo-colour when active. Exclusive with Odd.	`ClientPuduTxMode` / `ClientPuduRxMode`
Odd	Selects Behringer-lineage symmetric tanh shaping. Exclusive with Even.	`ClientPuduTxMode` / `ClientPuduRxMode`

Indicators¶

Indicator	Behavior
AetherVoice logo	Animated branded logo that pulses with the wet-signal RMS. Displays "AetherVoice™" wordmark. Minimum 40 px height.
Body group bracket	Group label — the three knobs below belong to the low-frequency processor (Drive, Tune, Mix).
Clarity group bracket	Group label — the three knobs below belong to the high-frequency processor (Tune, Air, Mix).

Using the value editor¶

Each knob supports inline value editing. Click a knob's displayed value text to activate the editor, type a number, then press Enter or click elsewhere to commit. The value is clamped to the knob's valid range. The editor accepts both locale-aware formats (e.g., "12,5" in comma-decimal locales) and raw numeric input. Press Escape while editing to cancel and revert.

Theme support¶

Knob colours and text colours throughout the PUDU applet now read from the theme system rather than using hardcoded values. The following theme namespaces control the PUDU appearance:

color.knob.background — the knob ring background track
color.knob.foreground — the knob arc that represents the current value
color.knob.handle — the knob pointer line
color.text.primary — the value text displayed below each knob
color.text.secondary — the label text above or alongside each knob

The PUDU applet container is registered under applet/pudu, which allows per-applet theme overrides. Theme overrides enable the amber PooDoo colour on the Even radio button when it is selected.

Bracket labels in both the applet panel and the floating editor use {{color.text.primary}} from the theme for their text colour, ensuring consistent appearance across different themes.

Tips¶

Keep Mix values moderate — both Mix defaults are 30 %, which blends the effect in without overwhelming the dry signal.
Body Tune uses a linear mapping across 50 – 160 Hz. For a typical male voice TX, tune toward the lower end of that range; for RX program material, tune to taste by ear.
Clarity Tune uses a logarithmic mapping, so the knob gives finer resolution at lower frequencies within the 1 – 10 kHz range.
The TX and RX instances are fully independent. You can run Even on TX and Odd on RX, or different Drive and Air amounts on each side.
When the PUDU stage is bypassed from the CHAIN widget, the applet tile dims visually. This matches the dim behaviour on the EQ curve and confirms at a glance that no DSP is being applied.
