Audio algorithms and tuning

ANC, ENC and EQ developed on the Bluetooth chip's DSP and tuned together with the acoustic design, so noise control, calls and sound fit each brand.

How a product sounds, and how well it handles calls and noise, is decided as much by software as by acoustics. Our audio team develops and tunes algorithms on the DSP of the Bluetooth chip, working alongside the engineers who design the acoustic structure. Because both sit in one team, the two are tuned together rather than one being forced to compensate for the other.

Algorithms

  • ANC (active noise cancellation): tuned to the acoustic structure and fit of each product, since the same algorithm behaves differently in a different housing.
  • ENC (environmental noise cancellation): background noise is reduced on calls, so the person on the other end hears the voice, not the street.
  • EQ: a factory sound signature for each product, plus user EQ in the companion app. Gigawit Control, for example, offers five presets and two fully customizable slots.

DSP customization on Kymera

Our audio work builds on Qualcomm’s Kymera audio platform:

  • configurable DSP processing chains
  • porting third-party codecs onto the platform
  • support for the full aptX codec family
  • our own low-latency codec, LightSync (see Bluetooth)

This lets a product carry features that are not in the chip vendor’s reference design.

Acoustic tuning

Tuning starts from the sound the brand wants. We agree a target with the customer, measure the prototype on our test equipment, adjust the acoustic structure and the DSP together, and refine by listening. The result is reviewed with the customer before it is frozen for production.

What it means for the listener

Noise cancelling that suits how the product is worn, calls that sound clear in noisy places, and a sound signature that is recognizably the brand’s own.

Frequently asked questions

Can ANC, ENC and EQ be tuned to our brand's sound?

Yes. Tuning is part of basic customization. The factory EQ sets your sound signature, and ANC and ENC are tuned to the acoustic structure and fit of your product. If you already have a house sound or reference product, we use it as the target.

How does the tuning process work?

We agree a target with you, then measure the prototype, adjust the acoustic structure and DSP together, and refine by listening. You receive tuning samples to review, and we iterate on your feedback until you sign off. The approved tuning is then frozen for production. The number of rounds depends on the project.

Can you integrate a third-party codec or audio algorithm we already license?

In many cases, yes. Our DSP work on Qualcomm's Kymera platform includes porting third-party codecs, and the same approach applies to other licensed audio processing. Feasibility depends on the chip's DSP resources and the form in which the licensor provides the code, so we assess it early in the project.
