Abstract
Disclosed is a method for implementing quality control for one or more components of an audio signal received from a communication device. In one embodiment, a Goertzel calculation is used to identify different frequency components of a selected sample. The identified frequency components of the selected sample may be analyzed based on predefined factors pertaining to the typical music and speech component of a typical audio signal. The analysis of the frequency component of the selected sample gives resulting values that is compared to a bottom threshold for determining whether the identified component is a music component or a speech component. Further, the classified frequency components may be graded based on quality parameters. The quality parameters may include a predefined frequency range, allowable deviation, and noise frequency range. Further, the classified frequency components of the audio signal may be improved based on grading of the classified frequency components.
