Are there any problems peculiar to analog recording in the matter of frequency modulation?
Yes. In analog recordings, we have speed variations at a higher frequency than flutters. When flutter occurs above a certain frequency, there is a grainy quality to the recording. Can you fix the problems that cassettes might present? We can, but cassettes are more difficult to fix. Howarth has a unique way of tackling the problems he encounters.) When a recording is made, there may be a background noise. For example, if the recording had been made in, say, a cafe there may be the background noise of a refrigerator. Or in some cases, there may be the noise of a fan or an air conditioner. The rhythmic ‘whir’ of a fan moves in consonance with the errors in the recording — it speeds up or slows down in accordance with the errors. So, I use this background noise as a cue to tweak the timing of the recording to make it similar to the original. Once, I fix the rhythmic background noise to make it sound as it must have originally, then I can fix the rest of the recording in a similar manner.
