In forensic analysis, the electric network frequency can often be used to determine the time and date that an audio recording was created. Many forensic scientists working with media question the quality and validity of audio evidence that was created by or has been converted to lossy compressed audio formats. The following work outlines a study designed to quantify the effects of lossy compression algorithms on electric network frequency signals. It shows that no forensic analysis based on the electric network frequency should be disregarded in legal proceedings solely for the reason that the audio file had been converted to any of the ten algorithms tested in this study.
