The audio side of video is often not well recorded due to small production budgets and short time frames. Therefore, during post-production, producers can be assaulted by a series of previous sonic missteps. An annoying rumble or hum in the low end is a common problem in audio recorded for video.

Software plugins that remove noise from audio abound and some function very well. However, under a fast approaching deadline, one may not have the time to find, purchase, and learn the nuances of a new plugin. For these situations, simply turn to the default equalization and reverbs provided in your audio or video editing software.

Use standard package plugins and the following tips to eradicate nasty noise from the bottom end of your audio recordings:

Initially you can try using a Single Band EQ to attempt to erase much, if not all, of the unwanted hum. Using such an EQ you can take away all the audio below or above a certain frequency. For instance, since a low end rumble from an air conditioner emits around 60 Hz then by placing a Single Band EQ at 80 Hz one can most likely eradicate most of the unwanted noise without damaging any voice tracks.

Next, target a very small width of the offending sound spectrum by using a Parametric EQ and "notching," which decreases a certain frequency and its octaves such as 80 Hz, 160 Hz, and 320 Hz. One preserves the surrounding audio by being able to target a small area of audio.

Next, a Parametric EQ can also be used to boost the wanted audio. Boosting the desired frequencies will give them prominence over the unwanted noise and thus redirect the listener's attention from the noise. For instance, put a small hump in around 5 Khz will amp the human voice over a lower rumble.

Fourth, after cutting out the lower end, a bit of reverb can be used on the mix. Such an effect can wash over and warm up a "tin can" feel that might come from taking out the bottom end.

Following the above strategies may not completely erase all problems associated with bad audio, but they can improve the quality of the product when unwanted noise and dialog are competing for attention in the mix.
