Title: Converting DAT > MT, weird questions
Post by: gmm6797 on February 21, 2007, 11:20:22 PM
Quick question for ya....

When converting old DATs, I am going from my R300 > MicroTracker via digital coax.

Some of my shows are coming out where the DATs sounds fine, but the speed on the WAV is ~33-50% too fast.  Any clue what could cause that?

I haven't messed too much with it, because on  the MT I can only hit record when using digital in, as it is considered a digital input and reads the proper settings from the incoming signal.

Any help is appreciated, thanks!

sounds like the recorder needs to have the sample rate set manually.

when going digital in, you are not able to change any of the settings, they come from the digital signal.

no bit depth, or anything can be changed

try setting the sample rate on the mt to the same as the dat -- prior top hooking it up.
a mismatched sample rate will cause a pitch change. so somewhere it's off, i'd bet.

dunno, i don't own one.

Had a similar problem with the JB3 doing similar transfers???

Some of my DATs start at 48k for about 1sec then switch to 44.1 or the other way around.  The JB3 locks onto the first but doesn't switch when the DAT does... 

I had to double check what the actual recording was and make sure the JB3 was recording the same...

see page 12. if followed by their words, you set your rate/depth before engaging record. fwiw, my 744 need to be told to record at 44 if i've previously set the rate at 96. i'm probably missing a setting on the box, but i do it too infrequently to care.

Just in case make sure you are set to 16 bit and sample rate auto under the record settings menu. I am not sure if the bit depth setting matters when taking SPDIF in but it can't hurt to make sure.
