In a volume control method applied to an audio processing system, firstly, a digital audio stream including a plurality of digital audio packets is received from a transmitter. It is determined whether an excitation signal is detected. The digital audio packets are sampled within a predetermined sampled period according to codecing rules, on condition that the excitation signal is detected. Output values corresponding to the digital audio packets are retrieved from the sampled digital audio packets according to the sampling operation. The digital audio packets are analyzed to generate sums of sampled frequency. An averaged volume level is calculated according to the sums of sampled frequency. An audio shift value is generated according to the averaged volume level and a predetermined standard volume level. Volume control is implemented to subsequently received digital audio packets from the digital audio stream according to the audio shift value.

1. Technical Field
The present disclosure relates to network communications, and more particularly to a volume control method and system typically applied to a Voice over Internet Protocol (VOIP) system.
2. Description of Related Art
Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
FIG. 1 is a block diagram of a typical volume control system applied to a VOIP system.
FIG. 2 is a flowchart of an exemplary embodiment of a volume control method in accordance with the present disclosure, the volume control method applied to a VOIP system.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references can mean “at least one.”
An exemplary embodiment of a volume control system of the present disclosure receives audio signals from an outgoing side, detects volume levels of the audio signals and, before the audio signals are transmitted to separate incoming sides for broadcast, implements volume control to the audio signals according to a preset or calculated volume level. Accordingly, the volume levels at separate incoming sides may be closer in value to each other. An exemplary embodiment of a volume control method carries out the above-described processes of the system.
FIG. 2 is a flowchart of an exemplary embodiment of a volume control method in accordance with the present disclosure. The volume control method is applied to an audio processing system, such as a VOIP system for example.
