Input Switch

Choose one of two explicitly connected inputs.

Visual walkthrough2 configuration controlsSynced audio walkthrough
See how it works ↓

Normal uses a 0.5-second equal-power crossfade; Slow uses two seconds. Shift-click offers the slow choice in the canvas. A lone connected source is audible only when its side is selected.

01 / Understand

The idea, before the settings.

Connect one source to A and another to B. The selected side is heard at the single output. Switching crossfades rather than cutting abruptly.

Input A + Input BInput SwitchOutput

Use it in AudioRouter

  1. Connect the two alternative sources to the switch.
  2. Choose the source to hear and select a fade suitable for the transition.
  3. Switch while both sources are active and listen through the whole fade.

What success looks like

One source replaces the other through a transition; this is not a permanent sum like Mixer.

If it does not work

If the chosen input is silent, check its incoming source before repeatedly switching.

Select the node to open Properties. Click its name to rename it. While playing, supported parameter-only edits save after a short pause. For structural edits, use Save when the canvas marks a change. Enabled and Bypass are distinct live controls; see the in-app help for their behavior.

02 / Explore

Make the behavior visible.

Input A is drums/bass; Input B is a bell melody. Listen to either reference separately, then Output while changing selection. Slow fade lasts two seconds in this example.

The example repeats until you press Stop, and control changes are heard immediately. The picture shows the tool's shape rather than time; follow the timing in Follow the sound below. This is not a DSP measurement or control for your running AudioRouter session.

03 / Configure

Every control, with a reason.

01

Active input

Which explicitly wired port is heard.

Range / choicesa · bDefaulta

↓ Lower / alternativeChoose A to transition toward A.

↑ Higher / alternativeChoose B to transition toward B.

Try thisA can be voice and B can be a backup source.

Keep in mind Selecting an empty side is silent.

↑ Higher / alternativeSlow uses two seconds.

Try thisChoose Slow for a leisurely program handoff.

Keep in mind The transition briefly contains both sources.

04 / Put it to work

Start with a useful example.

Example 1

Alternate two programs

  1. Connect program one to A and program two to B.
  2. Choose A, then B during playback.
  3. Use Normal for a deliberate transition.
Example 2

Make a slower handoff

  1. Choose Slow, or use the canvas Shift-click action.
  2. Switch once and allow the two-second fade to complete.

These are starting points. Compare at a comfortable monitoring level and adjust for your own source.

05 / Get unstuck

Small details that matter.

  • Input Switch is not a Mixer: it does not keep both inputs at full volume.
  • Selecting an unconnected side produces silence.
