    Noise Suppression Library
    This application library suppresses the noise interference
    in a speech signal, such as ambient noise picked up by
    a microphone while capturing speech. This algorithm is
    particularly useful for systems such as hands-free phones,
    speakerphones, intercoms and headsets where an isolated
    noise reference is not available. The algorithm handles
    0-4 kHz audio bandwidth and provides adjustable noise
    reduction up to 44 dB.
    Acoustic Echo Cancellation Library
    This library provides a function to eliminate the echo
    generated in the acoustic path between a speaker and a
    microphone, such as in a speakerphone or an intercom
    system. This library is compatible with the G.167 standard
    and provides 16, 32, 64 or 128 ms echo delays. It handles
    0-4 kHz audio bandwidth and provides echo cancellation of
    40-50 dB. It also includes some sample rate conversion
    functions.
    Line Echo Cancellation Library
    This library provides a function to cancel electrical line
    echoes caused by 2- to 4-wire conversion hybrids in
    telephone lines. The library can be used in long distance
    voice communication applications, especially in links
    involving satellite networks and intercontinental long haul
    networks, as well as digital networks, such as Voice over
    IP (VoIP). This library is compatible with the ITU-T G.168
    recommendation. The library can be used for full-duplex
    operation. It handles 0-4 kHz audio bandwidth (8 kHz
    sampling of 16-bit speech data).
    Equalizer Library
    The Equalizer library allows applications to change the tonal
    properties of a signal by offering an 8-band frequency band
    amplitude control. The library processes an 8 kHz sampled
    signal. The library works readily with the rest of Microchip’s
    dsPIC DSC Speech and Audio Processing Algorithms.
    Libraries for Speech and Audio Applications
    Speech Encoding/Decoding Libraries
    Three options exist for a variety of speech compression/encoding and decompression/decoding applications:
    ■ The library is an implementation of the ITU-T G.711 standard which uses A-law or μ-law
    companding to achieve 2: 1 compression.
    ■ G.726A is an implementation of the ITU-T G.726 Annex A standard which uses Adaptive Differential Pulse Code
    Modulation (ADPCM) encoding algorithm. It can achieve up to an 8:1 compression ratio depending on output bit rate
    selected.
    ■ Speex is a popular standard in the open source software community which has been adapted for the dsPIC DSC.
    It uses Code Excited Linear Prediction (CELP) algorithm. It can achieve a 26:1 compression ratio.

    dsPIC DSC
    Note 1: Includes both encoder and decoder processing in full duplex.
    dsPICDSC Automatic Gain Control Library
    The dsPICDSC Automatic Gain Control Library
    automatically adjusts the amplitude of a speech signal to
    match a set level. This is useful in speech applications
    where the distance between the speech source and the
    microphone is not fixed. The Automatic Gain Control Library
    can be used readily with Microchip’s Speech and Audio
    Solutions for speech signal pre-processing.
    Speech and Audio Fast Forward (SAFF)
    The dsPIC DSC Speech and Audio Fast Forward tool
    provides user’s with real-time control of Microchip’s Speech
    and Audio Processing Algorithms as they are running in a
    embedded system application. This PC GUI tool facilitates
    code generation and easy tuning of Microchip’s Noise
    Suppression, Acoustic Echo Cancellation, Line Echo
    Cancellation and Equalizer algorithms in speech and audio
    applications by simplifying parametric tuning of algorithms.
