Cart AGC (Software Codecs)
Adaptive Digital Technologies, Inc.
Description
The AGC algorithm performs gain adjustments incrementally at a rate determined by the input signal level to avoid distortion of the output signal. The algorithm also incorporates functionality to prevent excessive gain increases during prolonged intervals of silence.
Software Details
| Codec Type | Voice / Speech |
| Name or Standard/Profile | AGC |
| Audio/Voice Sample Rate | 8kHz |
| Operating System | Linux, Android, DSP/BIOS |
| Supported Tools/Features |
The Automatic Gain Control algorithm is used to automatically adjust the speech level of an audio signal to a predetermined value. In digital network-based equipment, audio signals come from different locations, each signal having its own nominal level. The AGC algorithm can be used to maintain the speech levels from these various sources at a common level so that subsequent processing operates on signals within a specified dynamic range.
