While the human ear is not as sensitive to the phase of audio frequencies (involving delays of less than 1/30 second), music professionals may favor certain equalizers because of how they affect the timbre of the musical content by way of audible phase artifacts.<ref>[http://emusician.com/tutorials/square-one-phase/ Linear Phase EQ, ''Electronic Musician'']</ref>

  Early telephone systems used equalization to correct for the reduced level of high frequencies in long cables, typically using [[Zobel network]]s. These kinds of equalizers can also be used to produce a circuit with a wider bandwidth than the standard telephone band of 300&nbsp;Hz to 3.4&nbsp;kHz.  This was particularly useful for broadcasters who needed "music" quality, not "telephone" quality on landlines carrying program material.  It is necessary to remove or cancel any [[loa(contracted; show full)*[http://www.wikirecording.org/EQ WikiRecording's Guide to Equalization]
