Turning audio spots into CTV and in-app reach
Sound-on video inventory as an audio channel: how Soundframe renders audio into VAST video, biases to interstitial placements, and opens curated deals to any DSP seat.
Audio buyers want living-room and in-app reach. Video inventory already has it. Soundframe is Waveband's answer: take an audio spot and a companion image, render a standard video creative, and traffic it on CTV, OLV, and in-app interstitial inventory from the same self-serve seat.
That is not a mute guarantee. CTV is structurally sound-on. On other environments we bias to publisher-declared video interstitial placements and say so plainly. The working demo lives at /features/soundframe.
Why render instead of waiting on audio creatives
Some seats cannot traffic classic audio creatives at all. Video creatives (VAST) are already live-fire verified on Waveband. Soundframe uses that path: the creative type stays video, channel compatibility and Signal quartile events stay unchanged, and you still get household attribution on CTV.
Operators keep control: optional sound-on bias on the line item, curated deals from the shelf, or open-exchange video with the rendered creative attached.
Buy through Waveband or from your existing DSP
The sound-on shelf is available inside Waveband for one-click activation into your deal library. The same packages appear on /marketplace for buyers who stay on another DSP seat: request a deal ID, and our team fulfills through a curation partner. Instant self-serve minting for external seats requires that partnership; until then the path is request-based, not automatic.
