  • SVE Wearable Solution

    SVE near-field product series are suitable for various types of wearable audio (WA) products. The solution innovatively integrates AI-neural network and digital signal process technology to improve the voice call quality of wearable devices in complex acoustic scenarios.

Technical composition & specification
SVE_WA solutions support products ranging from one microphone to multiple microphones and voice bone conduction sensors. According to the number of microphones and sensors used, SVE solutions are named by SVE1000/2000/3000/4000 etc.
  • Acoustic Echo Cancellation（AEC）

    Eliminate echo completely, residual echo < -60 dB; Convergence speed < 300 ms, no echo in the initial segment (Echo free); Support echo cancellation under high volume and heavy bass conditions; Support full-duplex calls

  • Noise Reduction（NR）

    Noise cancellation ranging in 25~40 dB, low voice distortion; Wind noise elimination ranging in 30~45 dB; Suppress steady-state and non-steady-state noise

  • Automatic gain control（AGC）

    Flexibly set the gain control range according to the requirements for transmitting/receiving loudness

  • Algorithm processing by frame

    Flexible frame length: 7.5 ms/8 ms/10 ms

  • Flexible sampling rate

    Support Wideband 16 KHz, narrowband 8 KHz; Support 32KHz Super-wideband (Optional)

  • Compatible with multiple platforms

    Supports popular SoCs and DSPs: BEStechnic, Bluetrum, Airoha hifi series, Qualcomm S51xx series Kalimba processor, WUQI 7036DSP, ADAU1860 Codec DSP, Knowles 8201 DMX core, etc.Other platforms can be quickly transplanted according to needs.

Mass production cases
SVE_WA solution can be adapted to a variety of wearable devices:TWS earphones, XR/audio glasses, watch bracelets, etc,Sound+ can assist client in doing evaluation by providing recording samples or prototype for demonstration.
