Most brands already make sound. The checkout chime, the app open, the founder's voice on a launch video, the playlist behind a product reel. The sound is there. What's missing is anyone asking whether it holds together.
A sonic brand audit answers that question. It's the diagnostic pass you run before you write a single guideline, commission a sound logo, or sign off on a new sonic identity. Skip it, and you end up designing in the dark, building a system on top of touchpoints you never mapped. Run it, and you walk into every later decision knowing exactly what you have, what's broken, and what's worth keeping.
This is the step we run first on every sonic branding project at Supadark. Below is how it works, what you measure, and how to turn the findings into something you can act on.
What a sonic brand audit actually is
An audit is not a creative brief and it's not a taste test. It's an inventory and a measurement. You collect every place your brand currently makes a sound, you judge each one against a consistent standard, and you produce a score plus a short list of fixes.
Think of it the way a designer treats a visual brand audit: screenshot every logo placement, every color, every font, then mark where the system breaks. A sonic audit does the same for the ear. The output is evidence, not opinion. That matters because sound is the one channel where teams trust their gut the most and document the least.
The audit has a second job: it sets the baseline. When you ship a new sonic identity six months later, the audit is the before to your after. Without it, you have no honest way to claim the work moved anything.
Step 1 — Inventory every sonic touchpoint
Start by listing every moment your brand reaches an ear. Be exhaustive before you judge anything. A typical inventory includes:
Product sounds — UI feedback, notifications, success and error states, onboarding cues, the sound a feature makes when it works.
Marketing audio — video intros and outros, ad beds, social reels, the sound logo if one exists, podcast stings.
Brand-owned spaces — hold music, voicemail, event walk-on music, retail or booth audio.
Human voice — how the founder or team sounds on camera, the tone of voiceover, accent and pacing choices.
Borrowed sound — licensed tracks, stock effects, the playlist someone picked once and never revisited.
For each one, note where it lives, who made it, and whether you have rights to it. That last column matters more than people expect. Half the sonic audits we run surface a track nobody actually licensed, which becomes its own fix.
If you work across web touchpoints, this is also where you flag implementation problems worth a closer look later. We've written separately about the most common interactive audio web design mistakes if your inventory turns up a site that autoplays sound or buries a mute control.
Step 2 — Score each touchpoint
Once the inventory is complete, judge each item against five criteria. Keep the scale simple: 1 to 5, where 5 means this is doing real work for the brand and 1 means this is actively hurting us.
Consistency. Does this sound belong to the same family as the others? A bright, synthetic notification next to a warm acoustic ad bed tells the listener two different stories.
Distinctiveness. Could a competitor swap their logo onto this audio and lose nothing? Generic uplifting corporate music scores low here because it's interchangeable. This is the heart of what separates real sonic branding from background noise, a distinction we unpack in audio branding vs sonic branding.
Emotional fit. Does the sound match what the brand claims to feel like? A studio that sells calm and focus should not greet users with a frantic stinger.
Technical quality. Loudness, format, file size, fidelity. A sound logo clipped to a low-bitrate file undercuts everything else. This is where web touchpoints often fail quietly.
Rights and ownership. Do you own or properly license it? Borrowed sound is a liability, not an asset.
Average the five and you get a per-touchpoint score. Average those and you get a sonic brand health score for the whole organization. That single number is what stakeholders remember.
Step 3 — Map the competitive sonic landscape
A brand doesn't sound good or bad in a vacuum. It sounds good or bad next to its category. So before you draw conclusions, listen to the field.
Pull the sonic touchpoints of three to five competitors and run them through the same five criteria. You're looking for two things: the conventions everyone shares, and the gap nobody has claimed. If every brand in your space uses the same warm piano and soft pad, that warm piano is now wallpaper, and the brand that ships something angular owns the room.
The most studied examples make this concrete. The contrast between how two streaming giants approach the ear is worth the time, which is why we broke down Netflix vs Disney sonic branding as a reference for what claimed sonic territory looks like in practice.
Step 4 — Find the gaps and the conflicts
Now read the scored inventory as a system. Two patterns will jump out.
Gaps are the touchpoints that make no sound but should. A purchase confirmation with no audio cue. An onboarding flow that's silent where a small reward sound would land. A launch video that opens cold with no sonic signature. Gaps are usually the cheapest wins, because adding one well-made cue often beats reworking five mediocre ones.
Conflicts are touchpoints that fight each other. The cheerful jingle in the ad and the sterile beep in the product. The founder's relaxed voice on a podcast and the high-pressure voiceover on the homepage. Conflicts erode recognition, because the listener never gets the same signal twice.
Write each gap and conflict as a single line with its score and a one-sentence fix. This list is the spine of everything that follows.
Step 5 — Turn the audit into a deliverable
An audit nobody reads changes nothing. Package the findings so a decision-maker can act in five minutes.
A clean sonic audit deliverable has four parts: the health score up front, the full scored inventory as a table, the prioritized list of gaps and conflicts, and a recommendation on what to build next. Keep the prose tight and let the table carry the detail.
That recommendation is the bridge to the next phase. In most cases the audit makes the case for a documented system, which is exactly what a sonic brand guidelines document exists to provide. The audit tells you what's broken; the guidelines stop it from breaking again. Run in that order, the two pieces of work compound instead of overlapping.
If the audit instead reveals that the brand has almost no sonic presence to fix, the recommendation shifts toward building from zero, and the relevant starting point is the process for sonic branding rather than a repair job.
When to run one
Run a sonic brand audit at four moments: before a rebrand, before commissioning any new sound work, when entering a new market or channel, and once a year as maintenance. The annual pass matters more than it sounds. Sonic identity drifts the same way visual identity does, one well-meaning exception at a time, until the system quietly stops being a system.
For agencies and producers selling this work, the audit is also the cleanest first deliverable to offer a client. It's scoped, it's concrete, and it surfaces the problems that justify the larger project. We covered how to position that kind of offer in how music producers can license to sonic branding agencies, and pricing it sensibly follows the same logic as the rest of the work in our sonic branding pricing guide.
A 10-minute self-audit
You don't need a full project to start. Open a blank document and answer these five questions honestly:
List every place your brand makes a sound right now. How many did you reach before you ran out?
Play your three most-used sounds back to back. Do they belong to the same family?
Could a competitor use any of them unchanged? If yes, that sound isn't yours.
Does anything autoplay, clip, or arrive at the wrong volume?
Do you own or license every sound on the list?
If those five answers make you uncomfortable, that discomfort is the audit working. The fix starts with writing it down.
FAQ
How long does a sonic brand audit take? A focused audit for a small brand takes a day or two. A large organization with product, marketing, and retail touchpoints can run a week. The inventory is the slow part; scoring moves fast once the standard is set.
Do I need a sound designer to run one? You can run the inventory and the self-audit yourself. Scoring distinctiveness and emotional fit reliably is where trained ears earn their keep, which is why audits are usually the first thing a studio delivers.
What's the difference between an audit and a sonic identity? The audit measures what exists. The identity is the system you build afterward. One is diagnosis, the other is treatment.
Sound is the channel most brands own by accident. A sonic brand audit is how you stop guessing and start with evidence. Map what you have, score it honestly, fix what conflicts, and document what works.
