Topic: Edirol R-44 - 4 Channel Recorder (Part II)

[Rick]

Call me stupid - but when late last night I was testing whether the R-44 does bit-perfect digital input, and it was coming out not at all right, I had the MS effect on...

From which first of all we can see that effects will affect the digital input, which is worth knowing.

Second, the digital level controls do not affect the digital input, which is also worth knowing (and of course that's the way it should be).

Third - and most important - when I record one minute from a CD into the R-44 via spdif, then rip that CD into my DAW and invert it against the R-44, I get silence - the spdif recording is bit-accurate.

For proof here's the readout from Audition for the mixdown of the two files, one inverted against the other -

   Left   Right
Min Sample Value:   0   0
Max Sample Value:   0   0
Peak Amplitude:   -inf dB   -inf dB
Possibly Clipped:   0   0
DC Offset:   0    0
Minimum RMS Power:   -inf dB   -inf dB
Maximum RMS Power:   -inf dB   -inf dB
Average RMS Power:   -inf dB   -inf dB
Total RMS Power:   -inf dB   -inf dB
Actual Bit Depth:   float

Using RMS Window of 50 ms

Eureka!  Sorry for the scare last night.  Never do stuff late.

Nice

Great work Lee.
What technique did you use to record the show?

Hypers, DINa, DFC, hung from the ceiling.  about 20' from the stage.  mics were about 10' from the floor, about 5' from the ceiling.  rca > xlr from the board.  50/50 matrix.

Oh yeah.  i'll post a couple of pics of the ceiling mount when I get home tonight.

This is at 25 pages so I am either going to suggest swapping to the team thread, or to have the OP (Rick) lock this and begin a new thread.

[leehookem]

Either or

[Ozpeter]

It's bound to resurface here in some shape or form anyway.
