ERA Noise Remover is the most suitable tool to repair your audio when it’s suffering from static background noises produced by fans, air-conditioners, electric hum & hiss, etc.
Hum and Buzz are two of the most common problems in audio recordings. Both of these noise types are usually caused by poor groundings in electrical installations, faulty wiring in the audio path or external electromagnetic interferences.
Hum normally sounds like a low-frequency tone based at either 50 Hz (for USA) or 60 Hz (for Europe), plus harmonics. If the harmonics are especially strong, the hum becomes an edgy Buzz.
Although ERA Noise Remover could already handle cases where a hum/buzz noise was affecting the audio, we implemented this extra module to improve the audible results even further. So, the next time a Hum/Buzz noise is hunting your audio, just enable the Hum/Buzz button to get rid of any persistent tonal noise.
Keep in mind that Hum/Buzz module will eliminate any hum or buzz completely, but it may add some artifacts to the useful audio, depending on the case. We strongly advise to use it only when it's needed.
