Every output on target, and the log to prove it.
SAudio measures and controls loudness on each SPO playout output. Automatic level brings programmes, promos and breaks to your target without pumping, a true-peak limiter holds the ceiling, and every item that goes to air gets its EBU R128 figures in the compliance log.

Top 20 Countdown
SAudio is in early access. Dolby E pass-through, 5.1 groups and dialogue-based loudness are on the roadmap. The meters shown here are an illustration, not a capture of the product.
What SAudio does
Built for the audio desk and the night shift.
- 01
Automatic level
Slow, loudness-based gain riding to your target (−23 LUFS by default) within ±12 dB. It holds still through pauses and silence and never pumps with speech.
- 02
R128 compliance log
Integrated loudness, max true peak and loudness range for every item that goes to air, per output and stereo pair, with CSV export.
- 03
EQ and true-peak limiter
Up to six parametric EQ bands and a look-ahead brick-wall limiter at −1 dBTP by default.
- 04
Works per SPO output
Processing runs inside the SONE server on the programme audio of each SPO output, per stereo pair of 8 or 16 embedded channels.
- 05
Loudness tiles in SMonitor
Each processed output gets its own SMonitor tile: out of range, limiter working hard, silence on air.
- 06
Live meters in any workspace
Momentary, short-term, integrated, loudness range, true peak and the gain applied, with a 60-second history.
Meters
Loudness you can read across the room.
The meters panel shows each output the way an audio engineer expects: momentary and short-term against the target band, true peak per channel against the ceiling, and what automatic level is doing right now.

Compliance log
Proof for every item that aired.
When an item leaves air, SAudio writes its integrated loudness, max true peak and loudness range next to the target, so a viewer complaint or a regulator’s question is answered in seconds.
