FRONTEND AUDIO CAPTURE FOR VIDEO CONFERENCING APPLICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240046957 titled 'FRONTEND AUDIO CAPTURE FOR VIDEO CONFERENCING APPLICATIONS
Simplified Explanation
The abstract describes a system and method for a frontend capture module of a video conferencing application. This module is designed to modify an input signal received from a microphone device in order to match predetermined signal characteristics, such as voice signal level and expected noise floor. The module consists of an input stage, a suppression module, and an output stage.
- The input stage amplifies the voice signal portion of the input signal and selectively applies gains defined by a gain table based on the signal level of the input signal.
- The suppression module selectively applies a suppression gain to the input signal based on the presence or absence of a voice signal in the input signal.
- The output stage further amplifies the input signal in portions containing a voice signal and applies a gain table to maintain a consistent noise floor.
Potential applications of this technology:
- Video conferencing applications: This technology can be used in video conferencing applications to enhance the quality of the audio signal by modifying the input signal to match predetermined signal characteristics.
- Voice recognition systems: The frontend capture module can be utilized in voice recognition systems to improve the accuracy of voice recognition by suppressing noise signals and amplifying the voice signal.
Problems solved by this technology:
- Inconsistent signal characteristics: The system solves the problem of inconsistent signal characteristics by modifying the input signal to match predetermined signal characteristics, such as voice signal level and expected noise floor.
- Noise interference: The suppression module effectively suppresses noise signals in the input signal, resulting in improved audio quality.
Benefits of this technology:
- Improved audio quality: By modifying the input signal and suppressing noise signals, this technology enhances the audio quality in video conferencing and voice recognition applications.
- Enhanced user experience: The consistent signal characteristics and reduced noise interference contribute to a better user experience during video conferencing or voice recognition tasks.
Original Abstract Submitted
disclosed are systems and methods for a frontend capture module of a video conferencing application, which can modify an input signal, received from a microphone device to match predetermined signal characteristics, such as voice signal level and expected noise floor. an input stage, a suppression module and an output stage amplify the voice signal portion of the input signal and suppress the noise signal of input signal to predetermined ranges. the input stage selectively applies gains defined by a gain table, based on signal level of the input signal. the suppression module selectively applies a suppression gain to the input signal based on presence or absence of voice signal in the input signal. the output stage further amplifies the input signal in portions having a voice signal and applies a gain table to maintain a consistent noise floor.
