Abstract
A computer device (100) for processing audio signals is described. The computer device (100) includes at least a processor and a memory. The computer device (100) is configured to receive a bitstream comprising a combined audio signal, the combined audio signal comprising a first audio signal including speech and a second audio signal. The computer device (100) is configured to compress the combined audio signal to provide a compressed audio signal. The computer device (100) is configured to control a dynamic range of the compressed audio signal to provide an output audio signal. In this way, a quality of the speech included in the output audio signal is improved.
Claims17
A computer device for processing audio signals, the computer device including at least a processor and a memory, wherein the computer device is configured to:
- receive a bitstream comprising a combined audio signal, the combined audio signal comprising a first audio signal including speech and a second audio signal;
- compress the combined audio signal to provide a compressed audio signal by:
- selectively reducing an amplitude of the second audio signal only within speech segments of the speech included in the first audio signal using a tube compressor, selectively increasing an amplitude of the speech included in the first audio signal using a speech compressor, and matching amplitudes of the first audio signal and the second audio signal using a dynamic compressor;
- and
- control a dynamic range of the compressed audio signal to provide an output audio signal;
- whereby an intelligibility of the speech included in the output audio signal is improved compared with that of the received combined audio signal.
A method of processing audio signals on a computer device, the method being implemented by hardware of the computer device including at least a processor and a memory, the method comprising:
- receiving a bitstream comprising a combined audio signal, the combined audio signal comprising a first audio signal including speech and a second audio signal;
- compressing the combined audio signal to provide a compressed audio signal, wherein compressing the combined audio signal comprises:
- selectively reducing an amplitude of the second audio signal only within speech segments of the speech included in the first audio signal using a tube compressor, selectively increasing an amplitude of the speech included in the first audio signal using a speech compressor, and matching amplitudes of the first audio signal and the second audio signal using a dynamic compressor;
- and
- controlling a dynamic range of the compressed audio signal to provide an output audio signal;
- whereby an intelligibility of the speech included in the output audio signal is improved compared with that of the received combined audio signal.
