Noise Suppression Library
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
Encoding system
Any microphone-based application that needs to
eliminate undesired noise
Any application that needs to eliminate noise
interference from signals received over a
communication channel
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
assembly application program
Full compliance with the Microchip C30
C Compiler, Assembler and Linker
Precompiled library archive files
Highly optimized assembly code, utilizing DSP
instructions and advanced addressing modes
Audio Bandwidth: 0-4 kHz at 8 kHz sampling rate
10-20 dB noise reduction depending on type of
noise

Demo application source code is provided
Accessory Kit available for purchase includes:
audio cable, headset, oscillators, microphone,
speaker, DB9 M/F RS-232 cable, DB9M-DB9M
null modem adapter and can be used for library
evaluation

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
assembly application program
Full compliance with the Microchip C30
C Compiler, Assembler and Linker
Precompiled library archive files
Highly optimized assembly code, utilizing DSP
instructions and advanced addressing modes
Echo cancellation for 16, 32 or 64 ms echo delay
or ‘tail length’ (configurable)
Fully tested for compliance with G.167
specifications for in-car applications
Audio Bandwidth: 0-4 kHz at 8 kHz sampling rate
Convergence Rate: up to 43 dB/sec.,
typically > 30 dB/sec.
Echo Cancellation: Up to 50 dB, typically > 40 dB
