For sound trucks
SpotFacil for sound truck operators
Write, voice and finish a client's message for the truck in minutes, with a mix made for horn speakers, ready-to-use scripts and a calculator to price the job.
Your first spot is free, with any voice, premium included, and unbranded.

Most sound truck jobs start the same way. The client wants to run tomorrow, doesn't have a message and doesn't know what to say. You end up writing it on a napkin, recording it on your phone in the cab and playing something that sounds like a phone recording in the cab.
Or the client hands you a file made for Instagram, and on the horns it sounds thin and muddy, and you turn the amplifier up until someone complains.
SpotFacil fixes both problems.
How it works
- Write the message. Type the client's name, the offer and the place, and the AI writes a script sized for a loop. Or paste the text the client gave you.
- Pick a voice. Choose an AI voice with the energy you want, or record your own and let the system clean it up.
- Add music. The library suggests a licensed track that fits the mood. You can also upload a track you have the rights to.
- Choose "sound truck" as the destination. The file comes out mono, heavily compressed, loud and without the bass that horn speakers can't reproduce.
- Download the MP3 and put it on the truck's player.
A new message, from scratch to the player, takes a few minutes. When the client changes the price on Friday night, you change one line and download again.
What matters for sound trucks
A mix built for horns. Mono, compressed, no low end. The voice carries over traffic without pushing the amplifier to distortion, which also means fewer complaints.
Ready scripts by business type. Grocery stores, butchers, furniture, gyms, grand openings, events. Start from one and adapt it to the client.
Short loops. The generator writes 15 and 30-second versions, with the name and offer repeated the way truck copy needs.
A pricing calculator. Enter your fixed costs, fuel, wear and wage, and get a minimum hourly rate, a day rate and a route estimate.
A rules checklist. Permits, quiet hours, volume and quiet zones to check before each route. Rules are local, so it tells you what to ask, not what your city says.
Spot production as a service. Many operators charge separately for writing and recording the message. With professional-sounding audio, that becomes an easy add-on.
Your first spot is free, with any voice, and comes without a watermark.
Frequently asked questions
Will the audio work on my truck's speakers?
The "sound truck" destination is mixed for horn speakers: mono, compressed and without bass. Test it on your system at the volume you normally use before the first route.
Can I use my own voice?
Yes. Record or upload it, and the system reduces background noise and evens out the volume before mixing it with music.
Is the music safe to play in public?
The library's tracks are licensed, royalty-free music for the spots you produce. Don't add popular songs from other sources unless you hold the rights.
Can I make spots for several clients?
Yes. Each spot is separate, and you can keep versions for each client and update them when their offer changes.
