1. 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.
