The tape in question was in a dream I had, although it's not
quite so simple as me listening to a tape in a dream.
At one point I believe I purchased the tape in a supermarket
within the dream. At another point, I am still dreaming, but
am listening to the tape (could it have been on headphones 
in the dream?)
And finally, the third situation involving the tape is when
I dream I wake up, and the tape is playing on a stereo
beside my bed - just before I wake up for real.
I am writing something of an introduction here, just as the
voice on the tape reads an introduction to the material
presented there. The dream I tell of here was not just about
the tape I listened to. There were many other parts all
within a very detailed environment which I attempted to
capture at 3:30am immediately after waking up.
Beginning at what I remember as the start of the dream, was
the least clear and I was worried that by the time I got to
writing about the end of the dream, I would have lost the
clarity I begun with. Nevertheless I continued in a mostly
linear fashion.

The "Zoom H4 Handy Recorder" aswell as being a portable sound recording device, can also be used as a USB sound device - a lot like a sound card in actual fact.

Although I already have a sound card, I wanted to use the H4 simultaneously with the M-Audio Delta 66 for Real-Time audio recording/playback/processing. There are two problems with this, and the first is that the two sound cards are completely different and cannot be kept precisely synchronised with each other.

The second problem comes down to the OS I use (GNU/Linux) and the audio server (JACK). Here, the accepted general rule is that only a single audio device, or sound card, can be used at once.

The simplest way around this, is to tell JACK to use the H4 as the input device, and the Delta 66 as the output device. Still, maybe the problem with synchronisation drift still occurrs?

Another method is to configure the sound driver software (ALSA) to merge both devices as a single virtual device, but this disregards the synchronization problem, and requires knowledge of some slightly esoteric configuration code.

The final way, is to use a third piece of software (netjack ?) which measures how much the clocks within each sound device drift and compensate by re-sampling on-the-fly the audio of one or the other. And aparently, this peice of software may be finding its way into a future version of JACK.

Incase you don't have a clue what all that means: digital technology is NOT perfect, nor perfectly reliable ;)
