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: bring an audio spot, a companion image, a script, or any mix; we generate what is missing, 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 classic 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.
- Bring audio, still, script, or any mix; render a VAST video creative
- Traffic on CTV, OLV, and in-app interstitial inventory
- Optional sound-on bias on the line item (not a mute promise)
- Signal quartile events and household CTV attribution still apply
- Curated sound-on packages for Waveband seats and external DSP requests
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 /formats/sound-on 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. Say that plainly to clients so expectations match operations.
Where Soundframe fits the audio channel story
Classic DAAST and VAST audio still matter when the inventory and creative path exist. Soundframe is for the common case where the creative is audio-led but the reachable inventory is video.
Treat it as an audio planning motion with a video trafficking path. Your rate card and client narrative can stay audio-first while the seat buys verified video supply.
Measurement and creative ops
Because the creative type is video, reporting and Signal events follow the video path you already trust. Quartiles, completion, and CTV household frequency are not a special Soundframe-only metrics invent.
Creative ops stays familiar: version the render, attach to line items, QA in the same creatives library as the rest of the book.
Practical launch checklist
Prefer your masters when you have them; otherwise write a script and an image prompt and preview the render. Attach to a CTV or OLV line with sound-on bias where it fits. Add curated deals when you need packaged supply.
If the client stays on another DSP, send them to /formats/sound-on to request a deal ID. Keep Waveband as the seat when you want plan, propose, and measure in one place.
