Audio Processors

Audio processors are integrated chips that are designed to enhance audio signals prior to transmission. While analogue processors converts sound wave into electrical signals, digital processing converts audio signals into digital formats.

Audio processors are typically used in speech recognition, acoustic fingerprinting and noise cancellation systems.

Types of audio processors

  • LFCSP – Lead Frame Chip Scale package
  • LQFP – Low profile Quad Flat pack package
  • SOIC – Small outline integrated circuit
  • TQFP – Thin quad flat pack
  • TSSOP - Thin shrink small outline package

Audio processors are available with a various pins, sizes, channels, audio formats and voltages.
