dsPIC30F Noise Suppression Library
The dsPIC30F Noise Suppression Library provides a
function to suppress the effect of noise interference
with a speech signal. This function is useful for
microphone-based applications, which have a potential
for incoming speech corruption by ambient noise
captured by the microphone. It is especially suitable for
systems in which an acoustically isolated noise
reference is not available, such as:
• Hands-free Cell Phone Kits
• Speakerphones
• Intercoms
• Teleconferencing Systems
• Headsets
• As a front-end to a Speech Recognition system
• Any microphone-based application that needs to
Features
• Only 2 user functions (“NoiseSuppressionInit”
• Full compliance with the Microchip dsPIC30F C30
• Simple user interface – just one library file and one
