Studio input
A playlist is not the only path. Audio arriving at the Studio machine's sound card can go straight on air, whether it comes from a microphone, a mixer or another program.
What it is for#
A few typical uses.
- A live announcement. Connect a microphone to the sound card and speak from every point.
- Putting another program's audio on air.
- Taking an external source, such as a mixer output, onto the broadcast.
Settings#
The Studio input screen has four settings.
| Setting | What it does |
|---|---|
| Input device | Which sound card is read |
| Receiver group | Which points the broadcast reaches |
| Sample rate | The rate of the source, preferably 48 kHz |
| Input mode | Mono or stereo |
Once a device is chosen the level meter runs live. Confirm the level here before going on air.
This is what it looks like in Studio.
Level#
The colours on the meter follow console habit. Green is the safe region, yellow is the edge, red is the peak.
If the peak keeps touching red, turn the source output down. Audio clipped at the input cannot be repaired further along the chain.
A very low input is a problem too. The leveler tries to lift it, and lifts the source's noise floor along with it.
Processing#
Audio from the sound card also runs through the broadcast chain. If a source arrives already processed, for instance a mixer with its own limiter on the output, the chain can be bypassed for that source alone.
See Audio processing for detail.
Together with the playlist#
While the studio input is on, the playlist is stopped. The two do not go on air at once, because both write to the same timeline.
When the announcement is over, close the input and the list continues from where it stood.
