Speech & Audio Solutions
Audio provides a means of communication, improves
ease of use and delivers entertainment. It can transform
the mood of an environment, help us escape a noisy
commute, assist us in machine interface or improve the
quality of life for the visually impaired. Bringing audio to
your application enhances its ability to meet the needs
of your customers. Bringing your product to market with
the right mix of performance and price in the timeliest
manner is important to your business. Microchip provides
microcontrollers, development platforms and free software
source code to help you bring a cost effective design to
market in the shortest time possible.
Audio Application Support
Featured Products
Most 8/16/32-bit PIC microcontrollers can generate
tones, alarms and musical notes in various applications.
The dsPIC DSCs and PIC32 MCUs have DSP libraries
included in their respective compilers to enable higher
performance and more efficient processing of high quality
audio. Many devices now offer I 2 S/SPI modules for more
convenient CODEC interface. The PIC32MX1/MX2 Series
of MCU’s offer CODEC master clock support with very
fine control for reduced CODEC cost and audio buffer
management.
