ACOUSTIC ECHO CANCELLER MODULE OVERVIEW CouthIT’s acoustic echo cancellation implementation is designed to continuously and adaptively cancels the unwanted echo generated by the coupling between the loudspeaker and the microphone

Automatic Gain Control (AGC)

Automatic Gain Control (AGC) MODULE OVERVIEW CouthIT’s Automatic Gain Control (AGC) module scales the speech signals to a specified value regardless of the variations in the input level in various

DTMF/Fax Tones

DTMF/Fax Tones MODULE OVERVIEW CouthIT Tones library implements the common tone generation and detection algorithms used in telephony applications. Dual-tone multi-frequency (DTMF) signalling is used in telephony applications such as

Dynamic Range Control (AGC)

Dynamic Range Control (DRC) MODULE OVERVIEW CouthIT’s Dynamic Range Compression (DRC) module adjusts the dynamic range of a audio signal based on the audio level of the input signal. The

Jitter Buffer

JITTER BUFFER MODULE OVERVIEW CouthIT’s jitter buffer implementation intelligently manages the network jitter experienced by IP packets having multimedia content to enable smooth play out of audio or speech without

Noise Suppression

NOISE SUPPRESSION MODULE OVERVIEW CouthIT’s noise suppression module enhances the speech signal by suppressing stationary and non-stationary background noises and other perceivable distortions with minimal degradation in the speech quality.

Sample Rate Converter

SAMPLE RATE CONVERTER MODULE OVERVIEW Sample Rate Converter (SRC) is used for converting a digitized speech/audio stream sampled at a specific frequency to a desired sampling frequency. The algorithm interpolates


VOIP ON ARM MODULE OVERVIEW CouthIT’s Voice over IP library is a bundled collection of software components that allows to make a end-to-end voice calls over IP networks. This module
