[78-L] Nero 15 dehum - any help appreciated

[Rodger J Holtin]

I'm certain the original was 60hz as regulated by the TVA when the cassettes
were new in the 1990s or before.  I'm sure the wow and flutter is going to
change that some, and since these are probably dubs, maybe even second or
third generation, from cassettes and/or reels, I'm lucky I get anything,
really.

 

The program does have some tune-ability in that I can select the 50 or 60,
and then select a width range around the selected frequency.  It also has
"automatic hum detection" which would seem just the ticket for a novice to
use, so I did.  Visually, it appeared to drop the noise by 10%, but I cannot
hear any difference when I do an A/B comparison.  

 

Thanks for the thoughts, guys.

Another thought is that the hum may not be exactly 50 or 60 cycles,
especially coming from a cassette. Does Nero make allow you to tune the
filter to something above or below 50/60? If you are working with a dub, or
a dub of a dub, there may be more than 1 hum source in your recording.
