Abstract:
1. An audio quality analyzing device, comprising: a first audio quality analyzing unit that picks up from a network a packet containing a bit stream obtained by a compression encoding of an audio sent by at least one terminal, during an audio communication among terminals, and, in addition to analyzing a header of said packet, the first audio quality analyzing unit: detects a deterioration of audio communication service quality by performing at least one of an analysis of a payload header and an analysis of the bit stream contained in said payload; notifies a detection result to an upper level device, wherein the first audio quality analyzing unit detects an abnormality of a device based on a level estimated by decoding a parameter related to a gain in the bit stream contained in said payload; a second audio quality analyzing unit that picks up from a network a second packet containing a control signal and analyzes said second packet; and wherein a detection result of the first audio quality analyzing unit is verified by an analysis result of the second audio quality analyzing unit.
