deep audio experience

Our team has years of experience with companies such as Amazon, Beats by Dre, Jawbone, Palm, and more. Below are a subset of product categories we have worked on:

  • 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 (similar to Amazon Echo)
    & 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 acoutics
  • 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)
