Picture the folder on a shared drive at most agencies right now. Inside it, a fifteen second cut, mixed for a feed where most people scroll past with the sound off. Somebody built that mix on purpose that way, layered so the visuals still land even if nobody ever presses unmute.
Now picture the deadline. The CTV buy is due end of day, and the fastest thing to do is drag that exact same file into the connected TV upload. Same file, same mix, same assumptions baked into every frequency choice. Nobody re-opens the session. Nobody asks whether the audio was built for this room.
That night, somebody actually watches it. Living room, real TV, soundbar doing what soundbars do, phone resting in their other hand just in case. The volume is already up. It was never going to be muted. And what plays is a mix engineered for the one environment guaranteed not to happen here.
That gap, between the file that got shipped and the room it actually lands in, is the whole story of what's happening with connected TV advertising right now. Budgets moved into this channel faster than most sonic strategies noticed. This isn't a hook borrowed from a stats deck. It's what's sitting in a shared drive somewhere today, waiting to go out the door exactly like that.
The Budget Moved Before Anyone Adjusted the Mix
The numbers behind that shift are worth sitting with, not because they're shocking on their own, but because of how fast they arrived. Connected TV upfront commitments are on track to overtake primetime linear TV in 2026, for the first time ever. Roughly 37.95 billion dollars is flowing into a screen that comes with sound on by default, no mute icon waiting to be tapped, no silent autoplay to work around.
243.6 million people are watching CTV in the US this year. That audience now accounts for 43.8% of total TV viewing time. In head to head studies, 57% of viewers actually said they prefer CTV ads over the traditional linear kind.
None of that reads like a niche experiment anymore. It reads like where the money already is. And that's exactly the problem. Ad planning, media buying, creative production, all of it has processes built up over years to move budget quickly once a channel proves itself. Sonic strategy doesn't have that same muscle memory yet, because sound was never the thing anyone had to plan around when the assumption was "most people watch muted anyway."
CTV broke that assumption overnight, at least for this specific channel. And a lot of teams simply haven't caught up to what that means for the audio file itself, not just the media plan around it.
Why the File Swap Feels Reasonable, and Isn't
It's worth being fair to the teams doing this. Nobody's being lazy on purpose. Under deadline, reusing an existing asset is the responsible move, not a shortcut anyone would call reckless. The social cut already exists, it's already approved, it already carries the brand's visual identity cleanly. Why wouldn't you reuse it.
Here's the part that gets missed. Marketing teams will A/B test headline copy for a feed ad. They'll run variants on the thumbnail, tweak the exact shade of a call-to-action button, all in service of a channel where the ad might get two seconds of attention before someone scrolls past. Then that same team will ship an unedited audio file into a channel where the ad is guaranteed to be watched with sound on, uninterrupted, in someone's actual living room.
Say that out loud and it sounds backwards, because it is. The channel that gets the least attention gets the most testing. The channel that gets the most attention, the one where sound is never optional, gets a copy-paste job. That's not a hypothetical failure mode. That's the default behavior across a huge share of CTV buys running today, quietly, without anyone flagging it as a decision at all.
Not every team is dragging the same file over out of pure habit either. Some genuinely believe volume solves the problem on its own, that a sound-on environment is automatically a more forgiving one for whatever audio happens to be sitting in the timeline. That belief deserves its own look, because it's the second half of why this gap persists.
Turning the Volume Up Isn't the Fix
There's a tempting shortcut in all of this: audible is audible, right? If the CTV ad plays with sound on, doesn't that solve the problem the muted social cut had?
Not really, and the reason matters. Loud and recognizable are not the same thing. A track mixed to be a pleasant, unobtrusive backdrop for a muted scroll doesn't become a distinctive brand signal just because someone's living room speaker happens to be playing it out loud. It's still doing the job it was built for: sitting quietly under visuals, not carrying a message on its own.
And the demands on that audio are only getting heavier. Shoppable and interactive CTV ads are projected to make up ten percent of all CTV ads this year. QR codes embedded in these spots are seeing scan rates as high as 70% for well known retailers. Voice-activated formats are letting viewers ask for more information out loud, mid-ad, without touching a remote.
That means the audio increasingly has to do actual work, not just decorate whatever's happening on screen. A QR code sitting quietly in the corner of the frame does nothing if nobody tells the viewer, out loud, that it's there and worth scanning. The voiceover carrying that instruction now carries as much weight as the visual design of the code itself, which is a job most CTV audio was never briefed to handle in the first place.
The Living Room Is a Different Room
Part of what makes this trickier is that the listening environment itself has changed shape. CTV audio isn't playing through a cinema system, and it isn't competing with the controlled silence of a movie theater. It's coming out of a soundbar or a built-in TV speaker, in a room with its own ambient noise, often while the viewer's phone is sitting right there in their hand as a second screen.
That's a meaningfully different sonic environment than the one most broadcast and social audio was originally engineered for. A mix that reads clearly on a phone speaker in a quiet office doesn't automatically translate to a living room soundbar competing with a dishwasher running two rooms over. And a mix that was built to survive being muted was never tuned for either of those rooms, because survival was the only brief it ever got.
This is the layer most teams skip past entirely. They think about the channel, CTV versus social versus broadcast, as a distribution decision. They rarely think about it as an acoustic decision, one that changes what "good audio" even means depending on where the sound actually lands.
"We Already Have a Great TVC Track" Isn't the Answer It Sounds Like
There's a specific pushback that comes up from teams who feel like they've already solved this: "we already have a strong soundtrack for our TV commercial, we're covered." That asset is real, and it's not wasted. But it was very likely mixed for broadcast, built around assumptions closer to cinema playback, maybe even designed for a linear TV slot where the surrounding programming controlled the listening context around it.
CTV is a different room, literally and acoustically. Reusing that broadcast mix wholesale isn't wrong exactly, but it usually leaves recognition sitting on the table, because it was never built to compete with a soundbar, a second screen, and a living room's worth of ambient noise all at once.
This connects to a broader contradiction that's easy to miss if you only ever think about "most ads get watched muted" as a blanket rule. That rule is true on average, and it's also exactly why the specific moments where sound turns back on matter so much more than teams give them credit for. We broke down that wider pattern in why your video ad needs to work with the sound on, looking at what happens the instant a prospect actually unmutes, and why that moment tends to get the least design attention of any part of the funnel. CTV is arguably the biggest version of that moment there is, an entire channel where sound-on isn't an exception, it's the default setting from the first frame. It deserves a dedicated pass, not a leftover mix borrowed from a different room.
This is precisely the kind of campaign and interaction audio work built at Dimulti Music, where the goal isn't a single audio file reused everywhere, but the same brand DNA deliberately remixed for the room it's actually going to be heard in, whether that's a muted feed, a broadcast slot, or a living room soundbar with someone's phone sitting three feet away.
What the Gap Is Actually Costing You Right Now
Here's the part that's easy to underweight because it doesn't show up as a line item anywhere. Every day a brand runs a copy-pasted social cut on CTV, it's not just missing an opportunity. It's actively spending real media budget to play an unrecognizable sound to an audience that's primed, by the channel itself, to actually hear it.
That's a strange kind of waste. It's not a wasted impression, the ad is seen and heard exactly as planned. It's a wasted signal. The one channel where a brand's sonic identity had a guaranteed, undivided moment to land got a version of that identity that was never built to be heard clearly in the first place. Every dollar of that 37.95 billion moving into CTV this year is buying attention. Only some of it is buying recognition, and the gap between those two numbers is entirely a function of what's happening in the audio, not the media plan.
Consider two brands running similar CTV spend against similar audiences. One is running a repurposed social cut. The other spent the extra day tuning the mix specifically for soundbar playback, made sure the sonic signature actually lands clearly in a living room, and treated the voiceover as load-bearing for any shoppable element in the spot. Same budget, wildly different odds of anyone remembering which brand they just watched. That difference doesn't show up in a media report. It shows up months later, in whether a customer can hum the brand's sound back or not.
It also shows up sooner than most teams expect, in the shoppable data itself. If a QR code in a spot is only getting scanned by people who already knew to look for it, that's not a design win, that's the audio failing to do the one job that would have made the number bigger. A voiceover that actually tells a distracted, phone-in-hand viewer why the code matters moves that scan rate. A voiceover that was never written with that job in mind just sits there, technically present, functionally silent.
The Window Is Still Open, Which Won't Last
Here's the actual opportunity hiding inside what looks, on the surface, like a risk. Ad spend moved to CTV faster than most sonic strategies did. That's uncomfortable for any brand ignoring it. It's a genuine advantage for any brand willing to close that gap early, while most competitors are still just uploading the muted cut and hoping it lands anyway.
This window won't stay open indefinitely. As CTV keeps eating into upfront budgets the way it's projected to, more teams will eventually notice the audio mismatch, the same way visual identity eventually became non-negotiable once a channel matured enough for everyone to be paying attention to it. Being early to fix this is a real, if temporary, edge. It's exactly the kind of gap that closes the moment enough brands realize it exists, and it costs nothing today except the willingness to actually check.
Before the next CTV buy goes live, pull up the actual creative and watch it the way a real viewer would. Real TV, sound on, phone within reach, no headphones cleaning up the mix artificially. Does it sound like it was designed for that room, or does it sound like it was built for a feed that was never going to play it out loud anyway. That five minute check is the whole difference between spending your fastest growing ad budget on attention alone, and spending it on attention that actually turns into recognition. Let's build audio that earns the volume it's finally getting, not audio that just happens to fill it.
