The dsPIC DSC Noise Suppression Library provides a
function to suppress the effect of noise interfering with
a speech signal. This function is useful for microphone-
based applications which have a potential for incoming
speech getting corrupted by ambient noise captured by
a 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 or Speech
• Any microphone-based application that needs to
• Any application that needs to eliminate noise
The Noise Suppression Library uses an 8 kHz sampling
rate. However, the library includes sample rate
conversion functions that ensure interoperability with
libraries and speech sampling peripherals configured for
higher sampling rates (9.6 kHz, 11.025 kHz or 12 kHz).
Key features of the Noise Suppression Library include:
• All functions can be called from either a ‘C’ or
• Full compliance with the Microchip C30
• Precompiled library archive files
• Highly optimized assembly code, utilizing DSP
• Audio Bandwidth: 0-4 kHz at 8 kHz sampling rate
• 10-20 dB noise reduction depending on type of

Preliminary
11.10 Acoustic Echo Cancellation Library
The Acoustic Echo Cancellation (AEC) Library
provides a function to eliminate echo generated in the
acoustic path between a speaker and a microphone.
This function is useful for speech and telephony
applications in which a speaker and a microphone are
located in close proximity to each other and therefore,
susceptible to signals propagating from the speaker to
the microphone resulting in a perceptible and
distracting echo effect at the far end. It is especially
suitable for these applications:
• Hands-Free Cell Phone Kits
• Speakerphones
• Intercoms
• Teleconferencing Systems
For hands-free phones intended to be used in compact
environments, such as a car cabin, this library is fully
compliant with the G.167 standard for Acoustic Echo
Cancellation.
Like the Noise Suppression Library, the Acoustic Echo
Cancellation Library also includes sample rate
conversion functions.
Key features of the AEC Library include:
• All functions can be called from either a ‘C’ or
• Full compliance with the Microchip C30
• Precompiled library archive files
• Highly optimized assembly code, utilizing DSP
• Echo cancellation for 16, 32 or 64 ms echo delay
• Fully tested for compliance with G.167
• Audio Bandwidth: 0-4 kHz at 8 kHz sampling rate
• Convergence Rate: up to 43 dB/sec.,
• Echo Cancellation: Up to 50 dB, typically > 40 dB
