Frequently asked questions
How long should the script be?
For a 30-second ad, about 45 to 50 words read calmly is a good target. A meter under the script says whether it fits, and the ad waits until it does.
Can I write the script myself?
Yes. Terrads writes a first script in your brand's tone, and you can rewrite any of it before you approve. After the ad is made, one line can be recorded again without making the whole ad again.
Which voices can I use?
Sarah, Rachel, Adam, Aria, Laura, Jessica, Matilda, Alice, Lily, Charlotte, Roger, Liam, Will, Eric, Chris, Brian, Bill, George, Daniel, Charlie and River, each with a sample to hear in the app. An audio ad always has a voice; the music can be left out.
Do I get a video too?
Yes. Every audio ad also comes as a 9:16 and a 1:1 video of the same spot, showing your product photo and closing on your headline. You also get a square picture for Spotify.
Where can I run it?
On Spotify, in podcasts and on streaming radio, and, as a video of the same spot, in feeds where audio runs as video. Each platform's lengths, file types and loudness are in our audio ad specs post.
