During childhood, the majority of the adverts that stick in our memory are the ones with the catchy music and jingles. In the 90s most ads on the radio and TV seemed to have elaborated, yet often cheesy, jingles and claims. Unfortunately, most original jingles have since disappeared.

However, having high-quality audio in your ads is still a game-changer in the advertising space. But how can your business take advantage of this in a scalable and affordable way?

The costs of Audio Production

There are many reasons why audio and video ads feel so much more generic than they used to 20 years ago: maxed-out media time, short campaigns, or cross-channel-marketing just to name a few. With the internet being omnipresent for the majority of people nowadays, advertising has accelerated and become more competitive than ever. 

On top of that, there’s an ever-growing discrepancy between the budgets of huge corporations as well as unicorns on the one side, and everybody else on the other. There are many unicorns that we could mention memorable ads from, however not so much because of their wit and memorability, but rather because of their sheer volume. That kind of media volume costs a lot of money.

Delivering More Value

In principle, radio and audio ads are not rocket science. Still, they require serious planning, concept work, and flawless execution. These things often take months, which equals a lot of expenses and time for your company. The worst part of it all is that you have no idea how the campaign will go down your audience, and what you could have done better.

The challenge is that audio production is not scalable. Yes, you can create 3 or 4 different versions and test them against each other but not only will that increase your production costs, it’s also still very limited in terms of version-testing.

That's why Aflorithmic created a solution for creating audio at scale. With you can now create thousands of audio ads in a matter of minutes. We think this is a no-brainer use case for our technology because it can address all of the issues previously mentioned, and offers limitless additional possibilities:

  1. Production cost and time to market

Instead of hiring an ad agency, contracting a matching voice actor, booking a studio, hiring an audio engineer, and polishing things up in post-production, you can now do all of this in minutes with, saving you thousands, as well as your precious time which is priceless.

  1. Personalization and dynamic content

Just imagine a drugstore offering a specific product range in some, but not all of their stores. Another case would be offering discounts for sunscreen when it’s hot outside, and umbrellas when it’s raining. You can now create automated ads that are personalized with different variables, making each ad feel personal and relevant to the listener. 

Another example would be offering tickets for the artist you’re listening to on Spotify if they have a concert coming up in your area, or a supermarket offering daily deals. Recording these would not only be expensive, but also the turnaround time would take longer than the offer being valid. And there are countless other options in industries such as Gaming, Health, Education and more.

  1. A/B and Multivariate-Testing

Given that audio production with is so fast and easy, you can now create an unlimited number of versions of your ad. You can try different copies, personalized and non-personalized content, different music choices, or different speakers. There is literally no limit to how many versions of your ad you can produce within minutes. will also produce a VAST file to go with your ad. This will make it incredibly easy to hand your ad over to a wide variety of advertising players.

  3. Select a speaker out of 500+ available text to speech voices in 60+ languages
  4. Select a sound design that matches the look & feel of your ad
