Bauer Media Audio this week released Sound Check Europe 2026, a large-scale research study showing that 96% of senior advertising and agency decision-makers across nine European markets plan to maintain or increase their audio advertising spend. The announcement, dated 29 April 2026 and issued from Hamburg and London, draws on responses from more than 1,000 professionals and is described by Bauer as one of the most comprehensive snapshots of audio advertisingattitudes in Europe.

The headline figure - 96% - is striking precisely because it sits against a long-documented structural imbalance. Audio accounts for roughly one-fifth of total media consumption across Europe, yet consistently attracts only around a 5% share of advertising investment. That gap is not new. PPC Land has tracked the persistent disparity between audio consumption and advertising budgets for some time, with the IAB releasing standardised guidance in June 2025 to address what it described as chronic underinvestment. What is new is the scale and the geography of the survey behind today's findings.

The methodology and scope

The research was conducted by Bauer Media Audio in partnership with Elevate Consultancy. Responses came from more than 1,000 senior agency and advertiser decision-makers operating across nine European markets. The study does not restrict itself to existing Bauer clients or partners; it positions itself as a cross-market temperature check on how the planning community views audio as a budget line item and a strategic tool.

Bauer Media Audio reaches over 63 million listeners every week across those nine countries, operating a portfolio that spans digital radio, streaming platforms, podcasts, and social media. That footprint gives the company a direct commercial interest in the study's conclusions, which is worth noting when weighing the framing - though the underlying numbers, such as the 1,000-respondent sample size and the nine-market spread, suggest genuine scale.

Core findings: intent, trust, and the measurement problem

The study's top-line finding - that 86% of advertisers now consider audio a core part of their media strategy - is supported by four more granular observations that cut to the heart of where the market stands heading into 2026.

Digital audio as a brand-safe environment emerges as the most settled question. According to the study, 70% of advertisers view digital audio as brand-safe and 66% consider it capable of delivering broadcast-scale reach while retaining digital targeting flexibility. Those two attributes together - safety and scale - are precisely the combination that programmatic buyers have historically struggled to find outside of walled-garden environments. That they now associate both with audio signals a meaningful shift in perception.

Podcast advertising is the fastest-moving sub-segment. According to the study, 82% of advertisers say podcasts reach highly engaged audiences, and 47% are planning to increase podcast investment. Yet the same respondents characterise the channel as underutilised, suggesting that recognition of its value has not yet translated into proportional budget allocation. This mirrors findings from other recent data points. Podcast advertising spending surged 26% year-over-year in Q3 2025, with nearly 1,700 new brands testing the channel for the first time in a single quarter, according to Magellan AI's Q3 2025 Podcast Advertising Benchmark Report. The IAB Australia data showed podcast advertising reaching $134 million in 2025, growing 13.5% year-on-year, faster than streaming audio's 5.0% rate.

Measurement and attribution remain the most significant structural barrier. According to Sound Check Europe 2026, only 13% of advertisers confidently use audio attribution tools. Yet 73% say that stronger effectiveness evidence would increase their investment. That combination - low confidence in measurement tools, high responsiveness to proof of performance - defines where the industry bottleneck sits. It is not audience size. It is not creative capability. It is the ability to demonstrate, within existing measurement frameworks, what audio actually contributed to a campaign outcome. Comscore addressed this directly in January 2026 by launching content-level audio contextual targeting and cross-platform campaign measurement on The Trade Desk platform. The integration covers streaming audio and a catalogue of 4.6 million podcasts, operating without cookies or user identifiers.

AI in audio production is rising but trust is fragile. According to the study, advertisers are adopting AI in audio for its speed, scalability, and efficiency. However, 38% cite trust as the biggest barrier, with concerns clustering around brand risk, the impact on human creativity, and overall quality control. This reflects a tension visible across the wider ad tech market: automation reduces cost and time-to-market, but in audio - a medium that relies heavily on tone, voice, and authentic human delivery - the stakes of a misjudged creative execution are high.

The investment gap in European context

European digital audio advertising crossed €1.05 billion in spending during 2024, the first time the channel had exceeded the billion-euro threshold, according to IAB Europe's 2024 AdEx Benchmark Report. That figure represents 18.3% year-on-year growth. Impressive in isolation, but modest when set against the total European digital advertising market, which reached €118.9 billion in 2024 - meaning audio's €1.05 billion represents less than 1% of the continental total.

The Bauer study's 5% investment share figure refers to audio's share of total ad investment rather than total digital ad investment, which partially explains the discrepancy between the two datasets. Either way, the direction is the same: audio attracts a fraction of the budgets its consumption share would justify. A Neustar analysis, referenced by PPC Land in June 2025, found that a 1.8% shift of media investment into audio produced a 23% increase in overall return on advertising spend for automotive advertisers. That kind of leverage ratio is rarely documented this precisely, which makes the measurement gap all the more consequential: the data to justify audio investment exists, but the tools to surface it within standard campaign reporting do not yet reach the majority of buyers.

What the operators are doing about it

Bauer Media Audio is not a passive observer of these trends. The company has spent recent months building the infrastructure required to capture the budget shift the study anticipates. In November 2025, Bauer Media Audio expanded its audioXi advertising network through a direct reseller agreement with TuneIn, adding inventory across Poland, Slovakia, and Portugal. The audioXi platform operates as a digital audio marketplace connecting advertisers with inventory across digital radio, podcasts, and streaming services, using Bauer's first-party data for targeting.

The company's wider strategy has also moved into out-of-home. Bauer Media completed its acquisition of Clear Channel Europe-North for $625 million in April 2025, adding 110,000 advertising sites across 12 European countries. The combined portfolio now spans 200 magazine brands, 150 audio brands, and those 110,000 OOH sites, giving the group a multi-format reach of up to 350 million consumer touchpoints across 16 European markets. That scale matters for the conclusions of Sound Check Europe 2026: cross-channel planning is one of the areas Bauer explicitly names as a priority for strategic partnerships with advertisers.

The broader ad tech market has been moving in the same direction. SiriusXM and YouTube struck a deal for audio ad representation, giving advertisers guaranteed impression-buying against audio-first moments on YouTube for the first time. StackAdapt added AM/FM broadcast radio inventory to its programmatic platform through an iHeartMedia integration in November 2025, allowing data-driven campaign execution across audio formats simultaneously. Amazon and SiriusXM expanded programmatic audio reach through a DSP integration that brings SiriusXM Media's 160 million monthly digital listeners into Amazon DSP targeting. These infrastructure moves - which happened before the Bauer study published - show that the supply side of the audio market has been building toward exactly the kind of scale that planners say they need.

Simon Myciunka's statement

Simon Myciunka, President of Bauer Media Audio and CEO of Bauer Media Audio UK, framed the study's findings in commercial terms. According to Myciunka: "Advertisers are no longer testing audio, they're scaling it. When 96% of the market is either increasing or maintaining audio spend, that signals a fundamental shift. But the bigger story is the opportunity. Audiences are already there, effectiveness is proven, and now is the time for investment to grow."

He went further, addressing the competitive calculus directly. According to the statement: "The direction of travel is clear. Advertisers aren't asking whether audio works anymore - they're deciding how fast to scale it. Those that do will see the advantage first."

On Bauer's own positioning, Myciunka described the company's approach in terms of partnerships rather than products: "For us at Bauer Media Audio, this is about turning that momentum into something actionable. We are working with customers on strategic partnerships that bring clearer impact, stronger cross-channel planning, better data integration, and measurable outcomes for advertisers across all our markets."

The language around "measurable outcomes" and "data integration" is significant given that only 13% of respondents currently report confident use of audio attribution tools. It suggests Bauer's commercial pitch to planners will lean heavily on closing that measurement gap as a precondition for the budget growth the study anticipates.

What the numbers mean for media planning

For the marketing community, Sound Check Europe 2026 matters primarily because of the three-way tension it documents. First, intent to spend is high - 96% of respondents are either maintaining or growing audio budgets. Second, strategic belief in the medium is broad - 86% call it a core part of their media mix. Third, practical measurement capability remains weak - only 13% feel confident in attribution.

That combination points to a specific risk. When budget intent outpaces measurement confidence, allocation decisions default to proxies: reach metrics, brand safety scores, or gut instinct shaped by previous campaigns. Media fragmentation has already forced advertisers to restructure budget allocation strategies across multiple platforms, and audio's investment-to-consumption ratio suggests it remains the most structurally underfunded channel relative to actual audience presence.

The podcast figure is worth isolating. According to the study, 47% of advertisers plan to increase podcast investment, yet many still treat it as underutilised. Given that nearly half of podcast listeners never skip their favourite show, the loyalty and attention characteristics of podcast audiences are well-documented. The gap between that documentation and actual budget allocation - described by The Trade Desk as a "significant imbalance" - is the same gap the Bauer study is measuring from the advertiser side.

AI deserves a closer read in this context. The finding that 38% of advertisers cite trust as the biggest barrier to AI adoption in audio is not simply a technology adoption problem. In audio, the creative output is the ad itself - voice, tone, pacing, and authenticity are not decorative elements but the core of what makes an audio placement effective. A misjudged AI-generated voice can undermine brand equity in a medium that operates on intimacy. The fact that more than a third of respondents flag trust, not cost or complexity, as their primary concern suggests that audio's AI challenge is qualitatively different from the same challenge in display or programmatic video.

Broader implications

Sound Check Europe 2026 was released as the wider audio advertising ecosystem in Europe is undergoing rapid structural change. Bauer itself is navigating significant internal shifts: the company recently announced the closure of its German digital publishing subsidiary, Bauer Xcel Media Deutschland, scheduled for September 30, 2026, citing AI search disruption to publisher traffic. The parts of Bauer being wound down or restructured are, as PPC Land noted, predominantly those most exposed to organic search traffic. The parts being invested in - audio, outdoor, radio - are the ones least dependent on Google referrals. Sound Check Europe 2026 is, in that context, partly a document produced by a company that has a material strategic need to make the case for audio investment.

That framing does not invalidate the findings. A 1,000-respondent sample across nine European markets, conducted with a named external research partner in Elevate Consultancy, provides a credible baseline. But the study's conclusions - and their commercial use - should be read with that context in mind.

The more durable finding may be the one that cuts across all the noise: 73% of advertisers would increase investment if effectiveness evidence improved. That is a very large majority waiting to be persuaded by data rather than conviction. If the measurement infrastructure that is currently being built - by Comscore, by The Trade Desk, by Triton Digital, by SiriusXM - delivers the standardised attribution that buyers say they need, the budget shift documented as intent in Sound Check Europe 2026 could, over the next planning cycle or two, begin to close a gap that has persisted, stubbornly, for years.
