Add air with Doo Harmonics¶
Use the Doo / Air knob to add harmonic excitement and presence to the high-frequency band. This raises perceived "air" on TX to make your signal cut through, or on RX to improve intelligibility of incoming audio.
Before you start¶
- The PUDU stage must be enabled in the audio chain. If it is not visible, enable it via the CHAIN widget on the matching TX or RX side.
- Open the Aetherial TX Poodoo™ or Aetherial RX Poodoo™ applet in the Applet Panel, or double-click the PUDU stage in the CHAIN widget to open the floating editor titled "Aetherial Poodoo™ — TX" or "Aetherial Poodoo™ — RX".
Steps¶
- Locate the Clarity group — the three knobs on the right side of the applet, under the "Clarity" bracket label.
- Turn the Air knob to set the amount of harmonic content added at the high-frequency band. The value is shown in dB below the knob.
- Watch the AetherVoice™ logo pulse increase as the wet-signal level rises. Use this as a rough indicator of how much processing is being applied.
- If the result is too aggressive, reduce Air or lower Doo / Mix to blend the effect back with the dry signal.
Settings are saved automatically. The value persists in ClientPuduTxDooHarmonicsDb (TX) or ClientPuduRxDooHarmonicsDb (RX).
What each control does¶
| Control | Default | Valid range | Persisted setting (TX / RX) | Behavior |
|---|---|---|---|---|
| Doo / Air | 6.0 dB | 0.0 to 24.0 dB | ClientPuduTxDooHarmonicsDb / ClientPuduRxDooHarmonicsDb |
Sets the amount of harmonics added at the Doo frequency band. Linear mapping. |
| Doo / Tune | 5000 Hz | 1000 to 10000 Hz | ClientPuduTxDooTuneHz / ClientPuduRxDooTuneHz |
Centres the high-frequency excitement band. Logarithmic mapping. Displayed as X.X kHz above 1 kHz, X Hz below. |
| Doo / Mix | 30 % | 0 to 100 % | ClientPuduTxDooMix / ClientPuduRxDooMix |
Blends the excited highs back with the dry signal. Linear mapping. |
Tips¶
- Start with Air at 6.0 dB (default) and Doo / Mix at 30 % (default), then increase Air gradually while listening to the effect on program material.
- The Doo / Tune knob centres the band where harmonics are added. Set it to match your mic's presence peak on TX, or to the intelligibility range of incoming audio on RX. See Centre Doo on the presence band for your mic (TX) or for RX intelligibility for that procedure.
- Even mode (Aphex-lineage) produces warmer even harmonics; Odd mode (Behringer-lineage) produces brighter odd harmonics. The character of Air differs between the two. See Pick Aphex (Even) vs Behringer (Odd) character.
Troubleshooting¶
- Air knob has no audible effect — The PUDU stage may be bypassed. When the stage is bypassed the entire applet tile dims to reduced opacity. Check that the stage is enabled in the CHAIN widget. See Bypass PUDU from either chain.
- Effect sounds harsh at moderate Air values — Lower Doo / Mix to reduce the wet blend rather than cutting Air entirely. See Blend the Doo excitement with Mix.
