“Radio Silence” · Episode 3 · From script to tracks · Sample values
01
The script knows its roles
Lines in round brackets become direction, lines in square brackets sound effects. The delivery – “whispering”, say – sits with the character name above the paragraph. You see it all while recording, without having to record a take for it.
02
Every character in view
From Premium you assign text to characters and produce on separate tracks. Sound effects, music and ambience live in your library.
03
Every voice in its scene
From Premium you give a character or a single paragraph a voice effect – telephone, radio, megaphone – or put them in a place: outdoors, in a church, under water. In Pro you build your own effect chains. In stereo you place every character left or right in the scene.
04
Record together, review precisely
In Premium you invite your cast by email and assign paragraphs. Voice actors set their own pauses and pronunciation in reading mode, and you apply what fits. For review, a link is enough from Premium: direction or the client listen to takes, pick favorites and comment at the exact spot.

Voice and data
Your voicestays yours.
AI helps with the script. You speak.
If you want, the AI suggests structure, characters and direction. The wording stays; you check and decide. SoloBooth does not generate or clone voices. Your recordings never go to an AI service and train no models.
Your project lives in Switzerland.
Projects, scripts and recordings are stored in Swiss data centers. AI prep also runs with a Swiss provider that neither stores your scripts nor learns from them. Auto-scroll and breath detection run locally in your browser.
Details are in the privacy policy.
Your work deserves a demo.
Publish up to three voice samples at your own SoloBooth address. From Premium it becomes a profile page with a request form, in Pro your own website – under your own domain if you like.

Frequently asked questions
What do I need to record?
A computer with Chrome, Edge or another Chromium browser and a microphone your computer recognizes – a USB microphone works as well as an audio interface.
Do I have to install anything?
No. SoloBooth runs in the browser. If you like, you can also install it as an app.
What happens if the connection drops briefly?
You keep working when the connection is gone for a moment. Your account, syncing and other online features need a connection again.
Can I export for free?
Yes. With Free you export as MP3, one file per chapter. WAV and the check report are included from Premium.
Does the check report guarantee acceptance by Audible?
No. It shows the measured technical values against the ACX requirements. The platform decides on acceptance.
What does beta mean?
SoloBooth is still being developed. Features and controls may still change.
