If you've noticed you keep reaching for the volume knob mid-podcast, you're not imagining it. Podcast ads, particularly programmatic ones inserted via dynamic ad insertion, have quietly climbed several decibels above the show audio over the last few years. This is why, and what a listener can actually do about it.
The short version
- Podcast ads are consistently louder than the show audio around them, often by 3 to 6 dB LUFS.
- The reason is loudness competition: advertisers optimise ad audio for attention capture, and podcast platforms have no equivalent of the broadcast loudness rules that keep TV ads in check.
- Listeners can level the playing field with volume-normalisation features in modern podcast apps, but the underlying incentive structure keeps ads loud by default.
- The apps that offer loudness normalisation for spoken-word audio are the ones worth switching to if this bothers you.
How loud are the ads, actually?
Podcast loudness gets measured in LUFS (Loudness Units Full Scale), the same standard used for broadcast television, streaming music, and film. Lower numbers mean quieter. For reference:
- Spotify normalises music to around -14 LUFS.
- Apple Music normalises to around -16 LUFS.
- YouTube normalises to around -14 LUFS.
- BBC broadcast target is -23 LUFS.
- Well-mastered podcasts typically ship around -16 to -19 LUFS.
- Ad drops inside those podcasts routinely hit -12 to -14 LUFS.
A four-decibel jump between show content and ad content is a genuinely noticeable loudness change. It's the same size jump you'd notice if a TV commercial came on louder than the show. On television, that's regulated in most jurisdictions (the CALM Act in the US, similar EBU R 128 practices in Europe). On podcasts, it isn't.
The result is that the ad reads and programmatic drops effectively "punch through" the show's audio bed. If you were listening at a comfortable level to a conversational podcast, the ad break can be 3 to 6 dB louder without any warning.
Why podcast ads got louder
Three overlapping reasons.
Advertiser competition. Ad creative is optimised to grab attention. When every ad in the marketplace is being mastered as loud as possible to stand out, the collective loudness floor rises. This dynamic has played out in music (the "loudness wars" of the 2000s), on radio, and on television before regulation stepped in. Podcasts are the current arena where it's unchecked.
Dynamic ad insertion mechanics. With DAI, the show audio and the ad audio come from different masters. The show may be mastered at -18 LUFS by a careful audio engineer. The ad might be mastered at -12 LUFS by a marketing team focused on impact. When the platform stitches them together at playback time, no normalisation happens by default. The listener hears the raw handoff.
No industry-wide loudness standard. Podcasts have no equivalent of the CALM Act. There is a rough set of recommended targets (the AES podcast loudness guidance from 2021 suggests -16 LUFS for stereo, -19 LUFS for mono), but adherence is voluntary and inconsistent. Ad supply houses have little incentive to comply because compliance means being quieter than the competition.
None of these are conspiracies. They're the natural equilibrium in an unregulated market where every actor optimises for local benefit.
What listeners can actually do about it
Three routes, in ascending order of effectiveness.
Route 1: turn on your app's volume normalisation
Most modern podcast apps have a volume normalisation or audio boost setting that measures the loudness of each episode (or in some cases, each ad break) and adjusts playback volume to hit a target LUFS.
The catch is that per-episode normalisation only helps at the episode level. If an episode is on average quieter than another episode, the quieter one gets boosted. But if the ads inside a single episode are louder than the show content in that same episode, per-episode normalisation does nothing to level them out.
The apps that go further and normalise within an episode (adjusting for loud sections vs quiet sections in real time) are the exception, not the rule. Overcast's Voice Boost does something in this direction. Pocket Casts has a Trim Silence feature that also lightly compresses dynamics. A handful of other modern podcast apps ship similar EQ-plus-compression presets tuned for spoken-word audio under names like "Enhance Voices" or "Speech Boost".
None of these fully eliminate the ad-vs-show loudness gap, but they narrow it enough that you don't have to reach for the volume knob mid-episode.
Route 2: use a podcast app that reduces ad exposure entirely
Different problem, different tool. If the loudness gap is what bothers you most, the loudness features above are the direct fix. If it's the ads themselves, the answer is to reduce ad exposure via a podcast app that helps you skip past them (or to subscribe to ad-free member feeds where available).
Many popular podcasts now offer ad-free member feeds to paying supporters, either via the podcast's own membership programme (Patreon, direct memberships) or via network-level programmes (SiriusXM subscriptions for Stitcher-network shows, Spotify Premium for Spotify Originals). If the shows you listen to most support this, it's often the cleanest solution.
For shows that don't offer ad-free feeds, a podcast app with silence-detection and skip-forward controls tuned for the podcast use case will get you past ads faster than the default 30-second skip button in Apple Podcasts.
Route 3: system-level equalisation and volume clipping
More technical, but worth mentioning. Both iOS and macOS have accessibility settings for audio balance, mono audio, and (on some models) dynamic range compression as system-level toggles. Android has similar in some manufacturer skins.
Enabling Reduce Loud Sounds on iOS (Settings > Accessibility > Audio & Visual > Headphone Safety, then Reduce Loud Sounds) will hard-limit peak volume in your headphones to a threshold you choose. It's blunt (it caps loud content, but doesn't lift quiet content), but it will keep an unexpectedly loud ad from making you flinch.
The industry angle: will loudness normalisation get standardised?
Maybe eventually. There's ongoing work at the AES on refining podcast loudness recommendations, and platforms like Spotify and Apple have shipped some backend normalisation on music that could theoretically be extended to podcasts. But the incentives against a strict standard remain strong: advertisers benefit from louder ads, and platforms benefit from advertisers who spend money.
The realistic outcome is probably per-platform normalisation at some point (Spotify or Apple deciding to apply a target LUFS across their ad inventory), rather than a cross-industry regulated standard like the CALM Act. Neither is imminent.
For now, the fix stays on the listener side. A modern podcast app with volume normalisation, plus judicious use of system-level audio settings, plus a preference for ad-free member feeds where the shows you love offer them, gets you most of the way to a comfortable listen without needing the whole industry to agree on anything.
Frequently Asked Questions
Is there a "correct" loudness level for podcasts?
The AES recommends -16 LUFS integrated for stereo podcasts and -19 LUFS for mono. Well-mastered podcasts typically hit these targets. Ad drops in the same podcasts often measure 3 to 6 dB louder than the surrounding content, which is why the jump is noticeable.
Does Apple Podcasts normalise volume?
Apple Podcasts does some per-episode loudness matching (episodes from different shows are broadly balanced), but does not offer within-episode volume adjustment that would level ad breaks against show content. Third-party apps like Overcast go further on this axis.
Are podcast ads louder on Spotify specifically?
Not systematically louder than other platforms, but Spotify's use of dynamic ad insertion means the ad audio and show audio come from separate masters and are stitched together at delivery. Any loudness mismatch between the two masters shows up directly at the join, without any normalisation pass in between.
Can I complain to a regulator about loud podcast ads?
Not in most jurisdictions. The CALM Act in the US covers broadcast television, not podcasts or streaming audio. The EBU R 128 practices in Europe similarly apply to broadcast, not podcast distribution. There's no direct regulatory body for podcast loudness.
What's the easiest one-setting fix?
If you use Apple Podcasts, turn on Reduce Loud Sounds in iOS Accessibility settings. It won't fix the underlying loudness gap, but it will hard-cap the peak volume of any ad that starts unexpectedly loud. If you use a third-party podcast app, enable that app's volume normalisation or voice-boost feature.
