This guide teaches you how to build a spatial audio UX design workflow entirely inside Figma, covering annotation systems, interaction states, and developer handoff. The full workflow takes roughly three to four hours to set up the first time and about thirty minutes per feature after that.

What You'll Build

  • A reusable spatial audio annotation component library in Figma
  • Interaction state flows for directional sound triggers, volume zones, and mute states
  • A prototype handoff spec that maps audio events to UI states developers can implement
  • A QA checklist for testing spatial audio UX before release

Prerequisites

  • Figma Professional or Organisation plan (for branching and library publishing, tested on Figma 116+)
  • Basic familiarity with Figma components and Auto Layout
  • A project that uses the Web Audio API, Howler.js, or a spatial audio SDK such as Resonance Audio or Mach1 Spatial
  • Optional: access to a design system already published in Figma

Step 1: Define Your Spatial Audio Interaction Model

Before opening Figma, you need a clear map of every audio event in your product. Spatial audio UX fails at handoff because designers skip this step and developers make guesses about what triggers what.

What audio events should you document?

List every sound your app produces. Group them into three categories: positional sounds (tied to a specific UI element or 3D coordinate), ambient sounds (background audio that reacts to user movement or scroll depth), and notification sounds (one-shot events with directional cues).

A common pattern in Australian productivity apps and Canadian gaming platforms is to use positional audio on notifications so users can locate an alert without looking at the screen. Document that intent here, not in code.

Write this list in a FigJam file or a linked Notion doc. You will reference it in every subsequent step.

Common pitfall: Listing only the happy-path sounds. Include error states, timeout silences, and fallback behaviours for users running without audio hardware.

Step 2: Build Your Spatial Audio Annotation Component Set

Annotation components give developers a visual grammar for audio behaviour. Without them, spatial audio intent lives only in your head.

How do you structure the annotation components?

Create a new Figma page called _Audio Annotations. Build the following four base components.

Component 1: Sound Origin Marker. A circular badge with a speaker icon at its centre. Add a boolean property called is-positional. When true, attach a directional arc to indicate the sound's angle relative to the listener (0 to 360 degrees). Use a Text property for the sound ID so developers can match it to their audio asset manifest.

Component 2: Volume Zone Overlay. A semi-transparent filled rectangle with rounded corners. Add a numeric instance property called db-attenuation that accepts values from 0 to minus 60. This tells developers how much the audio fades as the user moves away from the origin marker.

Component 3: Audio State Badge. A small pill component with four variants: Playing, Paused, Muted, and Error. Attach this to any UI element that has an audio state so developers know which component owns that state.

Component 4: Interaction Trigger Arrow. A directional arrow with a dashed stroke. Use it to connect a user action (tap, scroll, hover) to an audio event. Add a text label property for the event name, such as onEnterZone or onFocusElement.

Group all four under a single published library called Spatial Audio / Annotations. Publish to your team library immediately so every designer on the project pulls from the same source.

Pro tip: Use Figma Variables to store your decibel scale and angle values as Number variables. This lets you update the entire annotation system from one place when the audio engineer changes the falloff curve.

Step 3: Map Interaction States in Your Flow Diagrams

A spatial audio feature has more states than a visual-only feature. Every state needs a frame in your flow.

Which states are commonly missed?

Most designers document Playing and Muted. They miss: Loading (audio buffer not yet ready), Degraded (mono fallback active because the device does not support spatial rendering), Blocked (browser autoplay policy blocked the sound), and Interrupted (phone call or system alert suspended playback).

Create a new Figma page called Audio State Flows. For each feature that uses spatial audio, build a flow diagram using your annotation components from Step 2. Connect states with your Interaction Trigger Arrow component. Label each transition with the triggering event and the resulting audio behaviour.

For a mobile app screen that plays positional ambient audio when the user enters a map zone, your flow should include at minimum: Idle, Loading, Playing, Volume Zone Active, Exited Zone (fading), Muted by User, and Blocked by System.

Common pitfall: Building the flow on top of your production frames. Keep flow diagrams on a separate page. Mixing annotation layers into production frames breaks developer inspect mode and confuses handoff.

Step 4: Prototype the Audio Feedback with Figma Smart Animate

Figma cannot play audio files natively as of 2026, but you can prototype the visual feedback that accompanies spatial audio so stakeholders understand the UX before a single line of code is written.

What can you actually prototype without audio?

Use Smart Animate to prototype the visual response to audio events. For a volume zone, animate the zone overlay opacity from 0.1 to 0.4 as the user's avatar moves into the zone. For a positional notification, animate the Sound Origin Marker badge to pulse and rotate the directional arc toward the notification source.

Add a secondary prototype connection that shows the Audio State Badge switching from Idle to Playing. This is enough for a stakeholder demo and a usability test. For usability testing in Figma, use your prototype alongside a separate audio track played manually by the facilitator. This lo-fi approach is faster than building a coded prototype for every iteration.

If your team uses Framer for high-fidelity prototyping, export your component specs from Figma and rebuild the animated states in Framer with its real Web Audio API integration. That workflow is covered in a separate Lenka Studio article on scroll-triggered animation systems in Framer.

Step 5: Write the Audio Interaction Spec for Developers

The spec is the deliverable that closes the gap between design intent and implementation. This is where most spatial audio UX falls apart.

What should the spec include?

Create a dedicated Figma page called Audio Handoff Spec. For each audio event in your interaction model from Step 1, document the following fields as a Figma annotation or a linked table.

  • Event ID: a unique string that matches your audio asset manifest, for example zone_enter_ambient_01
  • Trigger: the user action or system event that fires this sound
  • Audio file: the filename and format, for example ambient_forest.webm (use WebM Opus for web, AAC for iOS)
  • Spatial parameters: pan position in degrees, max distance in scene units, rolloff model (linear, inverse, or exponential as defined in the Web Audio API PannerNode spec)
  • Fallback behaviour: what plays (or does not play) when spatial audio is unavailable
  • Accessibility note: the equivalent non-audio cue, such as a visual indicator or haptic feedback pattern

Link each spec entry back to the corresponding frame in your Audio State Flows page using Figma's built-in linking. Developers using Figma Dev Mode (available from Figma 116 onwards) can inspect the annotation, follow the link, and read the full spec without leaving the file.

Pro tip: Use Figma's Section feature to lock the handoff page. Set it to Dev Mode only. This prevents designers from accidentally editing the spec after developer review has started.

Step 6: Run a Pre-Handoff Audio UX QA Review

Before you hand off, check for the most common spatial audio design errors.

What does a spatial audio QA checklist cover?

Work through this checklist before marking the design as ready for development.

  • Every audio event has a corresponding visual or haptic fallback documented in the spec
  • No audio plays without a user-initiated action on first page load (required for browser autoplay policies in Chrome 66+, Safari 11+, and Firefox 66+)
  • All volume zone overlays use attenuation values between minus 6 dB and minus 40 dB. Values outside this range are rarely perceptible to users in real environments
  • The Muted state is reachable from every Playing state in the flow, in one interaction or fewer
  • WCAG 2.2 Success Criterion 1.4.2 (Audio Control) is satisfied: any audio that plays for more than three seconds has a visible pause or stop control
  • The spec includes a reference to the target SDK, for example Resonance Audio 2.0 or Web Audio API AudioContext, so developers know which rolloff model to use

Run this checklist as a design review session with at least one developer present. Spatial audio parameters that look correct in a Figma annotation often require adjustment once a developer tests them against actual audio hardware. Build that feedback loop into your process from the start.

If you are auditing a broader design system that includes spatial audio components, the workflow at Lenka Studio typically starts with a full design system audit before introducing new interaction patterns. That prevents annotation components from conflicting with existing token structures.

Frequently Asked Questions

Can Figma play spatial audio files directly in a prototype?

No, as of Figma 116 in 2026, Figma does not support native audio playback in prototypes. You prototype the visual feedback for audio events and test actual audio in a coded prototype or a browser-based staging environment.

What is the difference between spatial audio UX design and regular audio UX design?

Regular audio UX uses mono or stereo sounds with no positional information. Spatial audio UX places sounds at specific angles and distances relative to the listener, using HRTF (head-related transfer function) processing to create a three-dimensional sound field. The design workflow needs to document those positional parameters, which standard audio UX annotation does not cover.

Do I need a separate Figma library for each project that uses spatial audio?

No. Publish the annotation component set once to your team or organisation library. Any project can enable that library without duplicating components. Update the library centrally when your audio parameters change, and Figma will prompt all linked files to accept the update.

How do I handle spatial audio accessibility for users with hearing impairments?

Document a visual or haptic equivalent for every audio event in your spec. For positional audio, a directional visual cue (such as a pulsing icon that appears at the screen edge nearest the sound source) satisfies the intent. Reference WCAG 2.2 Success Criterion 1.4.2 and WCAG 2.2 Success Criterion 1.4.7 in your spec so accessibility is part of the handoff, not an afterthought.

Does this workflow work for VR and AR app design, not just web and mobile?

Yes, with one adjustment. VR and AR apps use full 360-degree spatial audio, so your Sound Origin Marker component needs a second angle property for elevation (vertical pan) in addition to horizontal pan. The rest of the workflow, annotation, state flows, spec, and QA checklist, applies directly.

Next Steps

Once your handoff spec is approved, schedule a 30-minute audio parameters review with your front-end developer before implementation begins. Walk through the rolloff models and fallback states together. Issues caught in that session cost minutes to fix. Issues caught in QA cost days.
