Mute audio for a slice from the VFO panel¶
Silence the audio output of a single slice without changing its AF Gain setting. Use this when you want to suppress a slice temporarily and restore its previous volume with one click.
Before you start¶
- AetherSDR must be connected to a FLEX-8600 radio.
- The VFO panel for the target slice must be open. If it is collapsed to a frequency-only strip, click anywhere on it to expand it first.
Steps¶
- Click the VFO marker flag on the spectrum display for the slice you want to mute. The VFO panel opens anchored to the marker.
- Click Audio to select the Audio tab inside the VFO panel.
- Click Mute. The button activates, and audio output for the slice stops. The AF Gain slider value is not changed.
- To restore audio, click Mute again. The button deactivates and audio resumes at the previous AF Gain level.
What each control does¶
| Control | Kind | Default | Behavior |
|---|---|---|---|
| Mute button (Audio tab) | Toggle button | Off | Mutes audio output for this slice without changing the AF Gain setting. Click again to unmute. |
| AF Gain slider (Audio tab) | Slider | 100 | Sets the audio output level for this slice (0–100). Unaffected by Mute. |
DSP tab changes in v0.9.7¶
The DSP tab now shows only radio-supplied noise reduction algorithms. The buttons for NR2, RN2, BNR, NR4, MNR, and DFNR have been removed from the VFO panel. Those algorithms are client-side modules; access them through the spectrum overlay menu or the AetherDSP applet.
The buttons present in the DSP tab are:
| Button | Algorithm |
|---|---|
| NR | Noise reduction |
| NB | Noise blanker |
| ANF | Automatic notch filter |
| APF | Audio peaking filter (CW mode only) |
| NRL | Noise reduction level |
| NRS | Spectral subtraction |
| RNN | RNN noise reduction |
| NRF | Spectral noise filter |
| ANFL | LMS notch filter |
| ANFT | FFT notch filter |
A shared DSP Level row appears below the button grid. It contains a slider and a numeric readout. The slider retargets automatically to whichever leveled DSP algorithm was most recently enabled. The label to the left of the slider shows the active target (for example, NR or NB). When no leveled DSP algorithm is active — or when only RNN, ANFT, or APF is on — the row fades out and slider interaction has no effect. The row remains in the layout at all times; it does not shift the button grid when it fades in or out.
Algorithms that support a level via this slider: NR, NB, ANF, NRL, NRS, NRF, ANFL.
Tips¶
- Muting a slice does not reset the AF Gain slider. When you unmute, audio returns at the same level it was before.
- If you want to silence a slice permanently rather than temporarily, drag the AF Gain slider to 0 instead.
- To access NR2, RN2, BNR, NR4, MNR, or DFNR, right-click the spectrum display to open the overlay menu, or open the AetherDSP applet.
