audio & voice systems engineering for consumer electronics

optimizing sound for various product form factors

Surfaceink’s audio and voice expertise spans electrical architecture, acoustics, tuning 3rd party DSP architectures for optimal speech/telephony and music playback, as well as testing and validation during prototype phases.

deep audio and voice experience

Our team has years of audio and voice experience with major companies across a wide-range of product categories:

  • headphones (over ear, on ear, & in ear)
  • mobile phones
  • tablets & e-readers
  • action cameras & high noise tolerant designs
  • bluetooth speakers
  • bookshelf and floor standings speakers
  • smart speakers & mic array technologies

technical capabilities

Our skillset spans many areas of audio design and development. We have a cross functional team that handles acoustical, electrical, mechanical, and SW challenges within audio subsystems of various form factor products.

  • electroacoustic component testing & selection
  • enclosure design for optimal acoustics
  • microphone sealing, boot/gasket design, and placement/tuning for array implementations
  • acoustic tuning for bass reinforcement – port structures and passive radiators
  • quick turn acoustic prototyping
  • evaluation of 3rd party audio DSP algorithms
  • codec and algorithm tuning for multiple audio silicon and software vendors
  • tuning for telephony, multimedia, and speech recognition applications
  • device prototype (EVT, DVT, etc.) testing & validation
  • production line testing (developing fixtures, test sequences, and limits)

advanced tools

Our team is trained in the use of well-known audio analyzers and hardware, CAD packages, and prototyping tools.

  • audio analyzers
  • audio measurement – reference transducers and systems
  • mechanical CAD
  • Electrical CAD & layout
  • 3D printing
