ams grows noise cancellation expertise with Incus Labs acquisition
ams claims the leading position as a supplier of analogue ANC to headphone and earphone OEMs, and says that Incus will strengthen its position, with noise cancellation system design tools for a new range of digital ANC solutions, that will bring reduced system cost and size, and improved design flexibility. Digital ANC solutions will offer OEMs easier implementation by eliminating the need to configure and assemble a hardware filter network of passive components tailored to each headphone or earphone design.
Incus’ IP can run on a variety of general-purpose DSP cores while providing the core ANC functionality in DSP-based solutions found in many bundled and aftermarket earphones and headphones today. Incus solutions, ams says, offer a high level of noise attenuation across a broad frequency range, using phase-shift technology which compensates for latency in the digital signal processing chain. Incus’ IP also supports the use of advanced speakers and micro-speakers for outstanding Hi-Fi quality audio reproduction.
The existing ams portfolio of analog ANC solutions includes products based on feed-forward, feedback and hybrid topologies, in both single-ended stereo and mono bridge tied load (BTL) versions.
