In the application experiment we applied the concept of signals and system to a practical signal. We took a audio file as a input from a directory .Then applied the parametric equalization to it.Parametric equalizers are multi-band variable equalizers which allow users to control the three primary parameters: amplitude, center frequency and bandwidth.Practically they can be used to adjust the volume level of a frequency, or range of frequencies, within an audio signal. We displayed the input and output signals on Spectrum Analyzer and then the processed file was played.
