Tune Bands on Either Side¶

The frameless editor is where you do all active EQ work: adding and removing bands, dragging them to new frequencies and gains, adjusting Q, switching filter types, and selecting a filter family. The applet tiles are view-only; this floating window is the editing surface.

Before you start¶

The Aetherial Audio (TXDSP) parent container must be visible in the applet panel.
The TX or RX EQ stage you want to edit must exist in the CHAIN widget. If the stage is not yet in the chain, add it there first.

Steps¶

Locate the CHAIN widget for the side you want to edit (TX or RX).
Double-click the EQ stage in the CHAIN widget for that side.
Double-clicking the TX EQ stage opens the editor titled Aetherial Parametric EQ — TX.
Double-clicking the RX EQ stage opens the editor titled Aetherial Parametric EQ — RX.
The frameless editor window appears at its default size (900 × 520 px). Its title bar shows which side is active.
To add a band, use the icon row along the top of the canvas area. Click the relevant band-type icon to insert a band at a default position.
To remove a band, select it in the canvas or parameter row and use the remove control in the icon row.
To tune a band, drag it directly on the canvas:
For peak and shelf bands: drag to adjust frequency and gain simultaneously.
For HP/LP bands: drag to adjust frequency and Q.
Hold Shift while dragging to adjust Q alone.
Click a band's icon to cycle through filter types.
To change the filter family applied to HP/LP cascade math, open the drop-down in the top strip and select one of: Butterworth, Chebyshev, Bessel, or Elliptic.
To freeze the analyzer's peak trace while tuning, click Peak Hold in the editor header strip. The button turns amber when active. Click it again to resume normal decay (~10 dB/sec).
To discard all edits and return to defaults, click Reset. This restores the default 10-band count and parameters and sets the filter family back to Butterworth. The reset saves immediately.
To close the editor, use the close button in the editor's frameless title bar. The applet tiles continue showing the summed curve for their respective sides.

What each control does¶

Control	What it does	Default
Canvas (drag — peak/shelf)	Adjusts frequency and gain for the selected band	Per-band defaults
Canvas (drag — HP/LP)	Adjusts frequency and Q for the selected band	Per-band defaults
Canvas (Shift + drag)	Adjusts Q only for the selected band	—
Band icon (click)	Cycles the selected band through available filter types	—
Filter family drop-down	Sets the math topology for HP/LP cascades: Butterworth (maximally flat passband), Chebyshev (steeper transition, 1 dB passband ripple), Bessel (linear phase, gentler rolloff), Elliptic (steepest transition, ripple in both bands). Persisted per path as `ClientEqTxFilterFamily` / `ClientEqRxFilterFamily`.	Butterworth
Peak Hold	Freezes the analyzer's per-bin peak-hold trace at its highest observed level. Located in the editor header strip. Turns amber when checked. Toggle off to resume normal decay (~10 dB/sec). Applies only to the floating editor — not the docked applet tile.	Off (unchecked)
Reset	Restores all bands to their default values, resets band count to the default 10 bands, sets filter family to Butterworth, and saves immediately. Tooltip: "Reset all bands to default values". Located in the editor header strip.	—
Output Fader	Vertical combined fader + level meter on the right edge of the floating editor. Drag to set post-EQ master gain; scroll wheel adjusts in 0.5 dB steps; double-click resets to 0 dB. The level bar behind the handle shows the smoothed post-EQ peak in real time with the same green-amber-red gradient as the Tube level meter. Persisted separately per path as `ClientEqTxMasterGain` / `ClientEqRxMasterGain`. Range: −36 to +12 dB. Located in the floating editor only — not in the docked applet tile.	0 dB
Smoothing	Applies fractional-octave power-averaging to the analyzer trace for display — does not affect EQ math. Lower fraction = smoother (⅓ is most smoothed; 1/96 is effectively off). Smoothing is applied after the peak-hold update each frame, so both the live analyzer trace and the peak-hold trace are smoothed for display. Shared between TX and RX editors. Persisted as `ClientEqSmoothingFraction`. Tooltip: "Fractional-octave smoothing applied to the analyzer trace. Lower fraction = smoother (⅓ = most, 1/96 = off). Affects display only — EQ math is unchanged." Located in the editor header strip (floating editor only).	Off (1/96)
Filter-type icon row	A row of 8 custom-painted icons (one per band slot) at the top of the editor canvas area. Each icon draws the current filter shape (peak bell, shelf ramp, HP/LP slope) in its band's palette colour. Click an icon to cycle through the filter types for that band; clicking also selects the band, highlighting its handle on the canvas and its column in the parameter row. Located in the floating editor only. Icons dim to 35 % opacity when the band is bypassed.	—
Parameter text row	A row of 8 text columns (one per band slot) below the canvas showing each band's Freq, Gain, and Q values. Values update live during canvas drags. Clicking a column selects that band. Located in the floating editor only. Each column has a transparent background so it does not bleed a dark fill over the band-plan strip at the bottom of the canvas directly above; labels are bottom-aligned within their column.	—
Filter cutoff guide lines (TX / RX)	Dashed yellow vertical lines overlaid on the canvas at the radio's current TX low/high filter cutoff (TX tile) or RX passband edges (RX tile). These lines are updated automatically whenever the radio reports a filter change. Hovering near a line changes the cursor to a horizontal-resize arrow. Dragging a line in the editor moves the radio's corresponding filter cutoff in real time.	—

Tips¶

The editor is a single shared window reused for both sides. Opening it on the TX side while it is already showing the RX side flips its title and content to TX. You cannot have TX and RX editors open simultaneously.
Changes save immediately through the audio engine. Closing the editor does not discard unsaved work.
Bypass is not controlled from inside the editor. To enable or bypass an EQ stage, use the CHAIN widget's single-click gesture on that stage.
The peak-hold trace in the docked applet tile decays continuously at ~10 dB/sec. The Peak Hold button in the floating editor freezes the trace only within the editor view.
The dashed yellow filter cutoff guide lines visible on both the docked applet tile and the floating editor update in real time whenever the radio changes its TX or RX passband, keeping the visual reference always current.
Display smoothing (set with the Smoothing combo) is applied after each peak-hold update. The peak-hold trace itself always tracks raw bins for accurate peak detection; the smoothed version is for display only.
In the parameter text row, each band column uses a transparent background. This prevents the dark application stylesheet from painting over the band-plan strip at the bottom of the canvas directly above the row.

Troubleshooting¶

Double-clicking the EQ stage does nothing — the stage may not be fully initialized if no radio connection is active. Connect to a FLEX-8600 and try again.
Peak Hold button stays lit after you stop using it — click Peak Hold again to uncheck it and resume normal analyzer decay.
Filter cutoff guide lines do not appear — if the radio reports a cutoff value of 0 for either edge, that guide line is suppressed. Verify that the radio has an active mode and slice selected.
Parameter row labels appear misaligned or crowd the band-plan strip — this was corrected in v0.9.7. If you see this on an older installation, update to v0.9.7 or later.
