Set room size for a small or large-hall feel¶
The Size knob controls the modelled room dimensions in the Aetherial FreeVerb TX reverb. Turning it up shifts the character from a tight booth toward a large hall.
Before you start¶
- The Reverb stage must be enabled in the CHAIN widget. If the "Aetherial FreeVerb" sub-container is not visible in the Aetherial Audio (TXDSP) panel, enable the VERB stage first.
- A radio connection is not required to adjust reverb parameters.
Steps¶
- Open the reverb controls using one of these two methods:
- In the Aetherial Audio (TXDSP) panel, locate the "Aetherial FreeVerb" sub-container and adjust the Size knob directly in the compact row.
- Double-click the VERB stage in the CHAIN widget to open the floating "Aetherial FreeVerb — TX" editor.
- Turn the Size knob left for a smaller, tighter room character; turn it right for a larger, more spacious hall feel.
- The knob label updates in real time and shows the current value as a percentage (for example,
50 %).
Live visualisation¶
The "Aetherial FreeVerb — TX" editor includes a compact waveform display (90 px tall) that updates in real time as you adjust any of the five knobs. It shows three overlaid signal layers:
- Cyan — the dry sine packet. Its amplitude decreases as Mix is raised.
- Yellow — first-order reflections. Spacing and count reflect the Size and Damp settings.
- Magenta — the reverberant tail. Length tracks Decay; damping of high frequencies tracks Damp; onset position tracks Pre-delay.
The display uses a dark background with a subtle grid. No interaction is required; it updates automatically whenever a knob value changes.
What each control does¶
| Label | Default | Range | Setting key | Behavior |
|---|---|---|---|---|
| Size | 50 % | 0 % to 100 % | ClientReverbTxSize |
Sets the modelled room size. Linear mapping. |
| Decay | 1.20 s | 0.3 to 5.0 s | ClientReverbTxDecayS |
Sets the reverb tail length. Exponential mapping. |
| Damp | 50 % | 0 % to 100 % | ClientReverbTxDamping |
Higher values damp high frequencies faster in the tail. Linear mapping. |
| Pre | 20 ms | 0 to 100 ms | ClientReverbTxPreDelayMs |
Pre-delay between the dry signal and the first reflections. Linear mapping. |
| Mix | 15 % | 0 % to 100 % | ClientReverbTxMix |
Dry/wet balance. Linear mapping. |
Tips¶
- Size and Decay interact closely. A large Size with a short Decay sounds unnatural; if you increase Size significantly, consider raising Decay to match.
- The live visualisation in the floating editor gives immediate feedback on how Size, Decay, Damp, Pre-delay, and Mix interact before you transmit.
- Both the compact applet knob and the floating "Aetherial FreeVerb — TX" editor control the same underlying parameters and stay in sync automatically.
- Double-clicking a knob resets it to its default value.
