Questions

Audio Production FAQ

Straight answers on cost, turnaround, formats, and how we work.

What is Sound Fire?

Sound Fire is an independent audio production company that creates broadcast-ready sound for brands and creators worldwide. We produce Spotify ads, radio commercials, voiceovers, podcast audio, sound design, and video mixes, working directly with clients rather than through an agency.

What audio services do you offer?

Our three flagship services are sound commercial production (Spotify ads, radio commercials, audio adverts), video sound mixing (dialogue, music, and SFX for film, TV, and social), and voiceover (English voice talent, casting, and direction). We also handle sound design, Foley and SFX, video game audio, podcast production and editing, music sourcing and licensing, e-learning narration, audio restoration, and audio branding (sonic logos).

How long should a Spotify ad or radio commercial be?

Most audio ads run 15 or 30 seconds. Spotify audio ads are capped at 30 seconds, and UK radio commercials are typically booked in 10, 20, 30, or 40 second slots, with 30 seconds the most common. We write and produce to the exact duration your media booking requires.

How much does audio production cost?

Every project is quoted individually based on length, complexity, voiceover, and music licensing, with no agency markup because you work directly with the producer. Tell us the brief, deadline, and where the audio will air, and we send a clear fixed quote, usually the same day.

How fast is your turnaround?

We confirm scope and questions the same day you get in touch, and most straightforward commercials and voiceovers are delivered within a few working days. If you have a fixed air date or campaign deadline, tell us up front and we plan the production around it.

Do you provide the script and voiceover talent?

Yes. We can write or polish the script, cast and direct the right voice, and produce the full mix, or work from copy and talent you already have. We offer native English voiceover plus a trusted network of additional voices for other styles and languages.

What file formats do you deliver?

We deliver mastered audio in whatever format your platform or station requires, commonly WAV for broadcast and MP3 for online use. Levels are mastered to spec, for example EBU R128 loudness for UK broadcast and around -14 LUFS for streaming platforms like Spotify, so your audio is ready to air with no further work.

Do you work with clients outside the UK?

Yes. Sound Fire is UK based and works remotely with businesses and creators worldwide. Briefs, drafts, and final files are handled by email and file transfer, so location is never a barrier to working together.
