This work explores a practical way of using digital signal processing to adjust the equalization curve of an audio signal, correcting the distortions produced by the acoustic response of the environment. Equipment such as signal generators, spectrum analyzers and equalizers can be used to correct these distortions, but its correct utilization requires technical knowledge not always available to the audio equipment operators.
