What Does ‘Broadcast Ready’ Actually Mean?

If you've ever looked into radio advertising, you've probably come across the term "broadcast ready." It sounds technical. It sounds like something you don't need to worry about — surely the radio station handles all of that?

Not quite. Here's what broadcast ready actually means, why it matters, and why getting it wrong can delay or derail your campaign.

The Technical Reality of Radio Broadcasting

Every commercial radio station in Australia — Nova, Hit Network, Triple M, Southern Cross, ARN, and all regional stations — has specific technical requirements for the audio files they receive. These requirements exist to ensure that every ad sounds consistent and professional when it goes to air, regardless of who produced it.

These specifications typically cover things like:

Loudness levels. Radio stations broadcast at a consistent loudness standard. If your ad is too quiet, it will sound weak on air. Too loud and it will sound distorted or cause issues with broadcast equipment. Getting this right requires professional audio mastering, not just turning up the volume.

File format. Most stations require WAV files at specific sample rates — typically 48kHz or 44.1kHz. Some accept MP3 at high bitrates. Submitting the wrong format can mean your ad isn't accepted or doesn't play correctly.

Bit depth. The resolution of your audio file. Professional broadcast requires 16bit or 24bit audio — not the compressed formats used for streaming or social media.

Duration. A 30second ad needs to be exactly 30 seconds — or within a very tight tolerance. Most stations will reject files that don't hit their duration requirements.

Why This Matters for You

If you produce an ad that doesn't meet these specifications, the station will either reject the file or ask you to resubmit. This causes delays — and if you're up against a campaign start date, delays cost you.

More subtly, audio that hasn't been properly mastered for broadcast can sound noticeably worse on air than it did on your laptop. Levels that seemed fine in your headphones can sound muddy, harsh, or thin coming through a car stereo at broadcast volume. The difference between a properly mastered broadcast file and an unmastered one isn't always obvious until you hear it on air. By then, the campaign has started.

What Broadcast Ready Means at Brand New Day

Every ad we produce is delivered broadcast ready as standard. That means the audio is mastered to the loudness specifications required by commercial radio, the file is formatted correctly for station delivery, and the duration is precise.

If a specific station requests different technical specifications — and some do — we provide those at no extra charge.

For Spotify and Apple Music advertising, we also master to each platform's specific loudness and format requirements, which differ from traditional radio broadcast standards.

You don't need to understand the technical details. You just need to know that when we deliver your ad, it will go to air without any issues.
