Reaper | Room Tone
Silence is golden. But it's a little too silent.
We actually don't want true nothing. We want "room tone" or the almost-nothing-not-quite-silence sound we (don't really) hear. Maybe dogs or dolphins can hear it but we can't. But I think they have hired dogs AND dolphins and ACX because they seem to know how to detect it.
We need to keep them happy so let's get them a room tone file.
