Common questions about electric hum

Can I loop the electric hum?

Yes: the files marked Prepared loop repeat without a seam. Loop the WAV; an MP3 adds a short gap where it starts over. The other files are single takes: for a long background, crossfade two files of the same kind.

Is there a fluorescent light buzz?

Yes: the Fluorescent Light Electric Hum files.

Is there an electronic hum for a tech scene?

Yes: the Deep Machine and Low Transformer Electric Hum files.
