Sonic Audit:
How to Analyze the Sound of Your Brand and Category
Before a brand can sound new, someone has to establish how it sounds today. That is exactly what a sonic audit does: an inventory of every acoustic touchpoint, a look at the sound codes of the category, and an honest consistency check. Skip this step and you are composing into the void.
The short version
A sonic audit maps where and how your brand already sounds, analyzes the sound of competitors and the category, and checks whether the sum is consistent. It belongs at the start of any serious sonic branding project, because it is what makes briefing, budget decisions, and later measurement possible. A first self-assessment fits into one afternoon, and the instructions are below.

1. What a sonic audit is
A sonic audit is to sound what a brand audit is to the visual side: a systematic inventory of what already exists, taken before anyone thinks about anything new. It answers three questions. First: where does your brand actually make sound today? Second: how does it sound in those places, and who decided that in each case? Third: does the sum of those sounds fit what the brand wants to stand for?
The most common surprise: practically every brand already has sound. The hold line has been playing the same royalty-free track an intern picked in 2019. The social team pulls trending sounds for Reels. The trade fair booth runs on the contractor's playlist taste, and the explainer video uses whichever voice happened to be available. Every single decision was defensible on its own. Heard together, they add up to an acoustic accident that has little to do with the brand.
The audit makes this state visible, or rather audible. At the end you have an inventory of all acoustic assets, an assessment of their consistency and fit, a map of the category codes, and a list of hypotheses about what a coordinated brand sound would have to achieve. That is the working basis for everything that follows.
2. Why the inventory comes before the project
You can commission a sound logo without an audit. It happens all the time, and it goes wrong remarkably often, for three reasons.
First: no baseline, no measurement. If you never documented how your brand sounded before the project and what listeners associated with it, you cannot prove any change afterwards. The research shows what is at stake: Ipsos measures audio branding 8.5 times more effective than purely visual campaigns, and Veritonic measures 77 percent of consumers recalling a brand more easily when a specific sound belongs to it. But you can only demonstrate such effects for your own brand if there is a before state to measure against. The audit delivers exactly that baseline. How the measurement works afterwards is covered in our article on the ROI of sonic branding.
Second: no category analysis, no differentiation. Every industry has acoustic conventions. Insurance sounds like warm strings and calm male voices, tech like clean synth pads, discount retail like fast jingles. If you do not know these codes, you will very likely compose the category average by accident and then wonder why attribution fails. If you do know them, you can decide which codes to serve and where to break them deliberately.
Third: no inventory, no sensible prioritization. Sonic branding budgets are finite. The audit shows which touchpoints actually carry reach and repetition and which merely sit on the list. The hold line with 40,000 calls a year beats the brand film that everyone loves internally and hardly anyone sees externally. Those decisions should be made before anything gets composed.
Practical note: The sentence we hear most often in first conversations is: "We do not really have any audio yet." It is almost never true. What it means is: nobody has ever written down what exists. That is precisely what the audit is for.
3. The four dimensions of a sonic audit
A useful audit works on four levels that build on each other. Leave one out and the picture comes out crooked.
| Dimension | Guiding question | Typical result |
|---|---|---|
| Touchpoint inventory | Where does the brand sound today, with which assets, at what reach? | Complete list of all acoustic contact points including owners and rights |
| Competitors and category | How does the category sound, which codes do competitors share? | Map of category codes and of unclaimed acoustic positions |
| Consistency check | Do the touchpoints sound like one brand or like many? | Assessment of contradictions, sorted by visibility and damage |
| Effect hypotheses | What should the sound achieve, and how would you recognize it? | Measurable assumptions as the baseline for later evaluation |
The touchpoint inventory covers more than most teams have on their list at first: advertising and social media, obviously, but also the phone system and voicebot, product sounds and app notifications, trade fairs, events and in-store audio, podcasts and webinars, internal formats like townhalls and e-learning. For each entry, note which asset runs there, who chose it, which rights exist, and how many people hear it per year.
For the category analysis you listen in a structured way instead of just collecting: the same touchpoints of your main competitors, noted by tempo, instrumentation, voice type, tonality, and recurring patterns. After ten competitors you will recognize the conventions on your own. Two lists become interesting afterwards: the codes listeners expect from the category, and the positions nobody has claimed yet.
The consistency check puts your own assets side by side, ideally in a single listening session. The question is uncomfortable and simple: would a stranger attribute these sounds to the same brand? System1 and TikTok measure 191 percent increased brand awareness in the first two seconds when brands are recognizable there. Those two seconds only work if the same acoustic signal can be learned across every channel.
Finally, the effect hypotheses translate what you heard into testable sentences: "Our hold line signals randomness; a dedicated sound scheme would raise perceived professionalism." Sentences like that force precision and make the later project measurable.
4. Step by step: your first self-assessment
For the first round you need no budget, just an afternoon, a spreadsheet, and headphones. Here is how to proceed:
- Build the inventory. List every point where your brand emits sound. Ask every department, not just marketing. IT knows the phone system, the events team knows the trade fair sound.
- Collect the assets. For each touchpoint, obtain the actual audio file or a recording of it. Call your own hotline and record it. Whatever you cannot collect is already a finding.
- Listen in one sitting. Play all assets back to back in a single session, ideally with colleagues who had nothing to do with them. Write down spontaneous impressions before anyone starts discussing.
- Listen to competitors. Repeat the exercise with your main competitors: their spots, hotlines, social channels. Note what everyone does the same way and who stands out recognizably.
- Assess. Give each of your own touchpoints two grades: does the sound fit the brand? Does it fit the other touchpoints? Sort the list by reach and you will immediately see where the biggest contradictions hit the most ears.
- Formulate hypotheses. For your three most important touchpoints, write one sentence each on what a better sound would have to achieve there and how you would recognize it.
If you would like some structure for this exercise, there are two free tools we built for exactly this purpose: The 15-Minute Sonic Audit walks you through the inventory as a self-test, and The Sonic Brand Score condenses your answers into a single figure you can use internally as a basis for discussion. Neither replaces a professional audit, but both show you where you stand in very little time.
5. When you need a professional audit
Self-assessment has a built-in limit: you hear your own brand with the ears of people who hear it daily. What is familiar sounds right. That is not a character flaw, it is habituation. An external audit pays off as soon as one of these conditions applies:
- Many markets, many touchpoints. Beyond a few countries and dozens of contact points, the inventory becomes a project in itself, and cultural differences in sound perception enter the picture.
- A rebrand is coming. When the visual identity is being rethought, that is the natural moment to rethink the sound as well, based on a proper analysis rather than gut feeling.
- Results must be provable. The moment a board member asks about the effect, you need a measurement design with a baseline, a sample, and defined KPIs. That is craft worth buying.
- Rights are unclear. If the inventory reveals that nobody knows which licenses cover the background music in the flagship store, you have an issue that goes beyond sound aesthetics.
A professional audit adds what is hard to produce internally: listener research with people who do not know your brand, a trained reading of the category codes, and the translation of the findings into a sound strategy with priorities and a budget logic.

An audit that ends up in a PDF graveyard was occupational therapy. The value emerges in the steps that follow, and they can be named precisely.
Prioritization and roadmap. Inventory and assessment turn into an order of work: which touchpoints get addressed first, what can wait, what simply gets switched off. Often the most effective first step is removing the worst contradictions rather than composing anything new.
Sound identity and guidelines. The unclaimed category positions become the basis for the actual sound identity: sound logo, sound world, voice profile, functional sounds. To make it last, audio guidelines belong with it, defining how the elements are used so that two years from now each department does not start making its own decisions again. How such an identity is developed is described on our sonic branding page.
Measurement. The effect hypotheses from the audit become KPIs: brand recall, attribution accuracy, emotional association. You measure against the baseline the audit documented. That is how "people seem to like the new sound" becomes a defensible result.
This is the real reason the inventory belongs at the beginning: it turns a matter of taste into a matter of strategy. A brand that knows how it sounds can decide how it wants to sound. A brand that does not is buying sound like decoration.
One closing thought: Start with the self-assessment, honestly and with open results. If it raises more questions than answers, that is not a bad sign but the normal case, and a good moment to talk to people who listen to brands for a living.

the sonic audit.
A sonic audit is the systematic inventory of all acoustic touchpoints of a brand, extended by an analysis of competitors and the category. It answers three questions: where does the brand sound today, how does it sound there, and does that sound fit what the brand wants to be. The result is an inventory, an assessment, and a list of hypotheses against which the later sonic branding project can be measured.
A first self-assessment with a touchpoint list and structured listening fits into one afternoon, and the self-test at soundproduc.ing takes a quarter of an hour. A professional audit typically needs several weeks, depending on the number of markets and touchpoints, because assets have to be collected, competitors listened to, and internal stakeholders interviewed.
It depends on scope: the number of touchpoints, markets, languages, and whether listener research is included. An audit for a brand with a handful of channels is a manageable project; a corporation with thirty country markets is commissioning a different order of magnitude. A serious quote requires a look at your touchpoint list first, which is why we do not publish flat rates. As a rule of thumb, the audit is the smallest line item of a sonic branding project and prevents the most expensive mistakes.
The first round, yes. Inventorying touchpoints, listening to competitors, checking consistency: your team can do that internally, and this article provides the instructions. Self-analysis reaches its limit at the assessment stage, because whoever hears their own sound daily stops hearing it. For listener research, measurement design, and deriving a sound strategy, an outside ear pays off.
