Tune the audio with Spelvin

Let the Mac listen to every source and Spelvin propose steps for each, then apply the ones you want.

Get a starting point for every source at once, with a reason for each, before the show. The Mac listens; Spelvin reads what it heard and proposes Live Producer’s own steps. Nothing changes until you apply it. See Processing.

  • Sign in, with Spelvin in your plan. A Tune Audio costs one action; a try that fails costs nothing. See Actions and limits.
  • Have the presenters speak as they will in the show, at their places, with their microphones.
  • For a place you return to, choose its venue first: Spelvin then starts from the room and the steps kept there.

In Window › Audio Routing (⌥⌘A), click Tune Audio… in the toolbar, or choose Audio › Tune Audio with Spelvin….

The sheet listens to every source with sound for 4 seconds, all at once. The sound never leaves the Mac: Spelvin gets numbers for each source, such as how loud the room is under the voice, how much the voice swings, a hum and whether it is at 50 or 60 Hz, rumble, hiss and clipping, the steps it has now, and whether a bus is playing to the PA.

The Tune Audio for This Show sheet: a row per source with its tick, Spelvin’s reason, the proposed steps and the delay now and after

Each source has a row: its tick, Spelvin’s reason, the steps with the preset each starts from (such as Clean Voice · Lav Mic), or No change, and its delay now and after. The foot says the picture’s delay now and after.

Spelvin names the cause when a step will not fix it. A hum at 50 or 60 Hz gets the Equalizer’s low cut and a note that it is likely a ground loop, which an isolator or another power socket takes away. Clipping gets a word about the gain.

Untick the sources to leave as they are, then click Apply. The ticked sources’ steps are replaced, as one undo (⌘Z). Cancel changes nothing.

  • The applied sources show the proposed steps in their processing half.
  • Hold to Compare in a step’s window lets you hear each change.
