Clean up a microphone

Take the noise out from around a presenter’s voice before it reaches the program, the stream and the recording. See Clean Voice.

Before you start

• Open the show, with the microphone’s source in it: an audio input, a camera’s microphone or a guest slot.
• Do what the room allows first: microphone close, fan off, gain below clipping. See Treat the room first.

Step 1: Add Clean Voice

Open Window › Audio Routing (⌥⌘A). On the source’s card, click Add Step in its processing half (the + when it has steps already) and choose Clean Voice under Live Producer. Or select the source in the main window and choose Audio › Add Step › Clean Voice.

The step is on at once, heard on the program too. Its row shows 30 ms.

Step 2: Open its window

Click the step’s row. The window shows the sound going in, in grey, and coming out, in blue.

Step 3: Learn the room’s tone

Ask the room to be quiet, then click Learn Room Tone. The Studio listens for 5 seconds; the room’s sound appears dashed in the graph, and the row says Learned with the time. Cancel stops it.

Step 4: Choose the strength

Strength	For
Light	a quiet room, a lav, a remote guest
Strong	a noisy room

For a lav in a quiet room, tick Quiet Between Words to silence the room between sentences, and lower Opens At if the start of soft words is cut.

Step 5: Compare

Hold Hold to Compare in the toolbar while the presenter speaks: you hear the source without Clean Voice. Let go to hear it again.

Verify

• The blue line in the graph is lower than the grey between the words.
• The status line under the columns says the picture is delayed 30 ms to match the source.
• ⌘Z takes the step away again if you change your mind.
