Topic: 24/96 s/pdif on Nomad JB3!?!?!?

[joemango]

just to be a shit, I recorded the Bomb Squad Halloween show at Tammany Hall in  Worcester MA using my laptop and my ua-5 in 24bit/96KHz mode.  Thinking that it would convert the bit rate down to 48 K, I plugged the optical out of my UA-5 into my Nomad and hit record.  It showed up as a 48 K WAV recording stream, and I figured I was all good.  Then I noticed that the time elapsed clock on the nomad was running a little fast.  TWICE as fast, in fact.  The thing was actually recording the 96 KHz stream at half speed.

I listened to it later, and it was indeed V E R Y  S L O W....  So I used Sound Forge and changed the sampling rate (without resampling) to 96 KHz and gods be praised, it was all there.  No dropouts, no weirdness.  Yes, it had truncated the signal to 16 Bits from 24, but you get that with a lot of digi-preamps anyway.  It sounded great.

So... Does anyone else think this is a bad idea?  Recording 96K with a nomad?

Oh  and P.S. - The recording time is ~1.5 hours max on a 96KHz stereo signal (truncated to 16 bit)

+T for crazy experiments!  no comment on whether it's a good or bad idea but it's cool that it's possible!

It'd be interesting to see if it was able to record bit perfect on the 96kHz stream... I doubt it, though.

oh yeah, +T for experimentation

so you taped 24/96 on your laptop and undithered 16/96 on the jb3?  have you dithered the laptop version and compared it to the truncated 16bit version?

Actually, I think the thread subject should read:  16/96 s/pdif on Nomad JB3.  

Pretty cool stuff, nonetheless.  If only it did 24-bits!  Even though it doesn't, I'm still considering replacing my portable DATs with it, but have to run through some signal converter testing first as I'd be running V3 > AES/EBU-opt converter > JB3.

Nope, haven't done that yet.  I'll check it tonight and let you know.  I might just post a sample of each.

I recorded the 2nd set of Mule in B'ham 24/48 lappy & ran the JB3 as well. The JB3 read 48K & sounded fine/normal (not slow)

I know this has nothing to do with this post but I thought I'd say it
