DBX I have yet to do more testing with, it worked ok but both decks I have require attention and I need to weigh up whether its worth spending the time on them.
I bought an outboard dbx NR box to play around with once. For the most part it worked well with my reel recorder, a few times it lost track of what to expand and what to leave compressed- but it was rare.
Now here's a cool thing: dbx encoded LPs! I had two of them. You heard the point snap into the groove... then... nothing! Absolutely silent until the music started! That was sort of a fore-listen to the noise floor and dynamic range of CD!
Honestly, I have no issue with digital recording in and of itself, but two things should be followed: a high sample rate for accordingly high resolution, and a deep bit depth for more detail in the waveform. In tandem, they produce greater transient response and higher frequency response. The 44kHz/16 bit of the audio CD is the barest passible minimum. On the liner notes of my digitally recorded "Malcolm Frager plays Chopin", Telarc used 50kHz at 16 bits. 16 bits allow 256 values for the shape of the waveform (slope, or rise), and the accuracy of representation depends on the sample rate (transients and wave shapes). Theoretically, digital recording can be absolutely flawless, the only errors being introduced by analog microphones, cable resistance and capacitance, and possible electron noise in preamps.
I think what we like about the vinyl product is a cumulative effect of flaws: the snapoff of the magnetic field "loops" as the tape passes the gap of the head, the resistance of the lacquer to being cut by the lateral excursions of the cutter point, everything in the chain contributing a softening and warming of the audio waves. This point was mentioned in the article, and it appears to be true. Pure digital recording is sharp and hard, like a surgeon with a scalpel that's so sharp it cuts too deep- previous surgical skills are insufficient to account for this sharpness, ablating an organ before it's repaired. The downsampling from the digital master to the CD format is the only flaw introduced, and there just ain't enuff flaw to make it warm 'n' fuzzy, so we get eardrum fatigue.
Digital recording made the editing process much simpler as well, but the first recording engineers weren't ready for the hard accuracy, and therefore produced hard sounding final products. The skills improved with time, but digital itself still remained sharp and cold.
The first CD I bought was Pink Floyd's "Wish You Were Here", actually bought it a couple of months before I found the player I wanted. I noticed that a
GOOD pressing of the LP opened with a faint touch of hiss from the master tape. I was surprised that the CD opened with the same hiss. From all the CDs I bought, it seems the best sounding ones were coded ADD or AAD, and the cold ones were DDD.
8 Tracks, well yeah I mean there is only so much they can do in terms of sound quality,
Yes the split tracks, very common, but so be it.
Song fades out, then a low frequency warble, ka-KLIK, and song fades in. No, no, absolutely NO! No noise reduction. Heads misalign with every ka-KLIK. By the way- the low frequency warble was to tell the manufacturing system where to cut the tape as it was wound onto the hub. The tapes were duped at high speed, all eight tracks simultaneously, and the higher speed made that warble into a tone that was monitored by a tape head to indicate that the whole of the program material was on the hub.
I'll give you
ONE good application for 8-track, and that's quadraphonic. There were only two programs of four tracks each, each being a discrete channel on the tape. You can identify these tapes by a notch on the front/top/left of the cartridge (as you are looking at the label end). If you find any, play it on your stereo deck and quickly hit the track button twice to hear the difference between the front and back programs. For a shits 'n' grins thought-
octophonic could have been introduced adding a height dimension to the music.
