I'm trying to record cassettes and LPs to my PC and am experiencing
line noise, possibly from some other device in the house. I have not
determined the source of this noise, but it occurs at random times
during the day, and causes clicks and pops that ruin any recordings. I
have tried moving the computer & audio equipment from the basemeent to
different rooms in the house and still am hearing noise.
The equipment being used is
* System: Pentium 4 PC running Windows XP Pro
* Softwa Sound Forge
* Audio Interface: Tascam US-428
* Cassette deck
* Turntable (with preamp)
I have used most of this equipment for a long time and not had
problems with noise like this in other houses/apartments, and I've
only noticed noise like this in this house in the past couple of
months (then again I haven't tried transferring LPs or cassettes in
this house, however I have recorded guitar/drums/etc here for a couple
of years and not experienced this kind of noise).
A recording of the noise and images of the waveforms can be heard &
seen he

Can someone tell what device in the house might be causing this (the
house has all the normal amenities - lights, A/C, W/D, etc.) or how to
filter this noise out of the signal loop before it reaches the
recordings?
Much appreciated!
From your recordings, this sounds like impulsive noise. Typical sources of
impulsive noise are electrical motors or other devices that create sparks.
The following gives an overview...

the other possibility is that your neighbour has recently bought a
Power-Line home network kit and is currently spurting RF noise in every
direction.

Refrigerator? Freezer? A/C?
Possible, but the pulses sounded a bit too frequent to be switches from
those devices.- Hide quoted text -

do the noise pulses occur at the SAME TIME in both the left and the
right?
in one case it sounded like no.
It is hard to imagine any EMI creating noise at different times in
the L and R.
