In a world where every interaction counts, sound has become a powerful tool for shaping how users experience technology. At Seltech, we’ve always been at the forefront of acoustic innovation—and today, we’re proud to introduce a new dimension to our expertise: custom sound design services.
Why Sound Design Matters
Sound is more than just an accessory. It’s a language—one that communicates identity, enhances usability, and creates emotional resonance.Whether it’s the subtle tap of a smartphone, the alert of a wearable, or the signature tone of a connected device, sound defines how users connect with technology.
With our new sound design capabilities, Seltech empowers brands to:
· Enhance user experience with intuitive and emotionally engaging sound cues
· Differentiate in the market with custom-designed audio that aligns with brand values
Our Two Pillars of Sound Design:
· Audio Tags
Audio tags are short, distinctive sound cues designed to provide immediate feedback or signal specific actions in a device. These sounds are often used in consumer electronics, such as smartphones, wearables, and smart home devices, where quick recognition and minimal disruption are key.
As illustrated in Figure 1, tags are crafted using sound synthesis, envelope shaping (1), and automated processing (2 and 3), converting in this example a basic sine into a smartphone taping sound for user feedback, as illustrated in Figure 2.
· Sound Design
Sound design at Seltech goes beyond short cues to encompass longer, more complex audio experiences. These are used in contexts where sound plays a functional and emotional role, such as:
• Electric vehicle (EV) signals
• Robotic movement effects
• Emergency sirens and alerts
As illustrated in Figure 3, sounds are typically built from layering of synthesizers (1, 2 and 3), cumulated with precise equalization to create in this example a Police siren that meets standard requirements.
A Creative and Collaborative Process
Our approach is both technical and artistic. Each project follows a structured yet flexible process:
• Understanding your needs and the context of use
• Defining the right service
• Designing and refining through collaborative feedback
• Delivering high-quality audio assets ready for integration
Let’s Craft the Sound of Innovation
At Seltech, we’re excited to help our partners design the future of sound—where every tone, tag, and texture is crafted with purpose.
