Sample Rate creeps up......what the????

[Mike H]

As an extra piece of information, I left the ProTools session open while I was typing the post above, with no playback going on. When I just now checked the sample rate on the Big Ben, it is up to 45.77. So, it just keeps slowly rising.

oo-err.... that does sound very odd....i'll do the same thing here with my gear and see if i can reproduce the problem....

i know this next statement is a bit of a smarmy OT kinda thing...and i might be doing things totally wrong my end... but .... why record the audio in in real time rather than just import the file direct off the cd...!!??

(maybe it's jus the studio elves in conjunction with the computer plotting to make you work at 96k the whole time!!!! lol)

This backing track was not sent to me as a file on a disk, but rather it was recorded as an audio CD. Yes, that was kinda dumb, but that is what they did.

Your point is still valid though. I could have recorded into a 96/24 session and converted the input. But I saw to reason to manipulate the data, since it was already down at 44.1/16.

Anyway, this was a good thing, since I will learn something from this. The question I am pondering now is: has this problem (whatever it is) been causing any mischief with earlier sessions, when I convert my 2-bus file from 96/24 to 44.1/16 into a new session, in preparation for burning a CD?

... back from control room.... very odd.... couldn't get it to do anything - sync'ed solid.... (blue light on whole time ....

re: importing audio.... jus Shift-Apple-I and import into session.... ok..so PT has to split the file into a .L & .R (why oh why doesn't PT natively handle interleaved files!!!come on Digi..sort it out!!lol) but... apart from that i wasn't aware it was doing any cunning trickery behind the scenes...

Eh?....surely the CD player should be master clock....you'll get no "pops 'n' clicks

I've had a similiar issue with the HEDD. Is the HEDD in your chain only outputing wordclock or is there some processing going on too?

Basically, I wanted to get the HEDD to output wordclock and also process audio at 44.1/16 so I could add the dither. The sample rate would go up to 48 when I tried this.

Dave Hill said the Hedd couldn't do what I was trying to do. I think he's looking into it.

The HEDD can work at 44.1/16 and add the dither and processing etc., it just can't do wordclock at the same time. I'm sure there is a perfectly logical reason for this. Maybe its too much to have the unit do so many things at once.

I don't know if this helps you, but I thought I would throw this in.

Good luck with it!

In this particular case I didn't have the HEDD doing anything else.

However, your input is very useful since I do use the HEDD to both (1) act as master wordclock and (2) dither when I am going through steps to convert files from 96/24 to 44.1/24 to 44.1/16, in preparation for burning a CD. So I need to discuss my situation with Dave. Thanks for the info!
