Capture audio with 24-bit sound card

[dgopman]

Dear All,

I would like to use an audio box to record with various sampling rates (44.1-192 kHz) and 24-bit I/O using the LabVIEW  I have run the Sound Device Input vi and I get a returned bit-depth of 16 bits. Can anyone suggest a way to confim/reconfigure the setup so as to realize the full recording depth of my hardware? I am using LabView version 8.2.

Much thanks,

Daniel

Hi Daniel,

Thank you for posting! I'm afraid we might need some further information on the hardware you are tying to use, since it seems you are having little trouble setting it up the way you want. It would be very helpful to know what is what you are conecting to your computer and how (serial, usb, gpib...)

Cheers!

Hello Brahim310,

The error you are seeing is a result of the bcdUSB device descriptor which should be 0x0200 not 0x200.

See this knowledge base article

I see !

so in this case it can't works,

is there any solution that can be done to make it work

I've been looking into it and I apologize I gave you some misinformation. The error that you are seeing is similar to the link that I sent you however the issue seems to be with one of the other descriptors that your USB device is referencing. Unfortunately, I haven't been able to find documentation as to what can be done to fix these types of issues. You might want to look for possible device drivers made from the device company you are using.
