My only concern is that the isolator might modify the data stream in some way (like maybe a lower frequency response curve for the transformers Transformers do have non-linear characteristics. One of the more noticeable effects is the loss of low bass frequencies. Transformers that are substantiall...

Which outputs on the mixer have you got connected to the computer - the RCA "tape outputs" or the 1/4" jack "Main Out" (or some other)? Do you have a "master" control on the mixer that controls the overall level for the output that you are using? (for example, the ...

@Koz, Have you got, or could you rustle up a strongly reverby track with real reverb that I could try Postfish Deverberation on?

FWIW I've tested recording and playback through my H2 and the timing is extremely close - I've only recorded a couple of minutes, but the "tempo" seems to be spot on and the playback length is exact as accurate as I'm able to time. Are you playing back through the Realtek sound card or thr...

[Update]
I've just been trying out Postfish and to my amazement the "Deverberation" seems to actually work

Here's the before and after of my first test:

The spectrum will change due to materials absorbing different frequencies to different degrees - this will not affect the frequency of the spikes in the spectrum, but the amplitude of the spikes will change as the reverberation decays. Very few bathrooms and conference rooms feature Helmholz resonat...

Excellent - you're getting close to tracking down the source of the noise. If you plug your headphones directly into the mixer, can you hear the hum in your headphones? If you completely unplug the turntable from the mixer do you still hear the hum? By the way, where is the "phono (RIAA) pre-am...

And works famously as long as the show arrives on the "left" cables. If it doesn't, you get a perfect mono recording of empty track noise. Good point koz - If that happened it would be necessary to either swap the cables round, or record in stereo and discard the empty channel. I think mo...

Starting the highpass at 110 instead of 80 retains more warmth? I see why you question that and you are right - on it's own, highpass at 110 will remove more warmth than at 80Hz (especially as I used a 12dB/octave filter at 110Hz and you used a 6dB/octave filter at 80Hz). It is the combination of t...

Which version of Linux are you using? Is it a standard or customised installation?
