Watch live gain reduction while speaking or listening¶

The ClientCompApplet shows a live gain-reduction meter and an animated transfer curve while audio is passing through the compressor. Use these indicators to see how hard the compressor is working in real time — while transmitting (TX side) or while receiving audio (RX side) — without opening the floating editor.

Before you start¶

The Aetherial Audio (TXDSP) parent container must be visible in the applet panel.
The compressor stage you want to monitor (TX or RX) must be enabled — the tile renders at reduced opacity when the stage is bypassed. See Bypass the compressor from the chain if the tile appears dimmed.

Steps¶

Locate the "Aetherial Compressor" sub-container (TX side) or "Aetherial AGC-C" sub-container (RX side) inside the Aetherial Audio (TXDSP) parent container in the applet panel.
Speak into your microphone (TX) or let received audio play (RX).
Watch the Gain-reduction bar — the horizontal amber strip below the transfer curve. The strip fills from the right as gain reduction increases, up to a maximum of 20 dB.
Watch the Transfer curve — the live envelope ball moves along the static curve to show the current input level relative to the threshold and ratio settings.
Use the -6 dB tick mark on the Gain-reduction bar as a reference. A fill that consistently reaches or slightly exceeds that tick is a typical working amount of compression.

What each control does¶

Control	Kind	What you see	Notes
Transfer curve	Indicator	Static input/output curve with a live ball at the current envelope level.	View-only in the applet; editable in the floating editor.
Gain-reduction bar	Meter	Horizontal amber strip, right-filled. Scale runs 0 to 20 dB of gain reduction. A tick marks the -6 dB point.	Refreshed at approximately 30 Hz with smoothed ballistics.
Thresh	Knob	Current threshold. Default -18.0 dB; range -60.0 to 0.0 dB.	TX: `ClientCompTxThresholdDb`. RX: `ClientCompRxThresholdDb`.
Ratio	Knob	Current ratio. Default 3.0; range 1.0 to 20.0. Displayed as X.XX:1.	TX: `ClientCompTxRatio`. RX: `ClientCompRxRatio`.
Attack	Knob	Current attack time. Default 20.0 ms; range 0.1 to 300.0 ms.	TX: `ClientCompTxAttackMs`. RX: `ClientCompRxAttackMs`.
Release	Knob	Current release time. Default 200 ms; range 5 to 2000 ms.	TX: `ClientCompTxReleaseMs`. RX: `ClientCompRxReleaseMs`.
Makeup	Knob	Current makeup gain. Default 0.0 dB; range -12.0 to 24.0 dB.	TX: `ClientCompTxMakeupDb`. RX: `ClientCompRxMakeupDb`.

Tips¶

If the Gain-reduction bar never moves, the input level is not crossing the threshold. Lower the Thresh knob or raise your microphone gain.
If the Gain-reduction bar is pegged at or near 20 dB continuously, the ratio or threshold is set very aggressively. Raise the Thresh value or lower the Ratio knob to ease the compression.
The envelope ball on the Transfer curve rests at the threshold line when no audio is present. During audio, it travels along the curve; a ball sitting in the bent portion of the curve confirms active compression.
Both the TX and RX tiles update independently. You can monitor both simultaneously if both sub-containers are expanded.

Troubleshooting¶

The tile appears dimmed — The compressor stage is bypassed. The tile now renders at approximately 55 % opacity when the stage is disabled, matching the dim effect used on the EQ curve. Enable the stage from the CHAIN widget (single-click the COMP stage) or see Bypass the compressor from the chain.
The Gain-reduction bar shows no movement during audio — The input level is not reaching the threshold. Reduce the Thresh knob value or check that the correct audio device is active and producing signal.
The envelope ball does not move — The applet is not connected to an active audio engine. Verify the radio is connected and audio is flowing through the relevant TX or RX processing chain.
