Dear all,
I am currently working on my final year physics project, where my lab partner and I are trying to build a set up which allows the detection of nerve impulses in MRI scanners. Essentially we're just using a low noise amplifier, and sending the signal digitally via SPDIF to a mac.
The sampling rate of the ADC on our amplifier is at 48000Hz, and so we try to set everything on the mac to sample at 48000Hz too.
However when we plug the optical cable into the mac, the sampling rate, as seen on the Audio MIDI setup, automatically changes to 44100Hz. This is causing us many problems. We've tried many things to get around this but with no success. Is there a program or something anyone could please suggest that could fix the input sampling rate permanently??? I'm 99% sure the problem lies here and not in the sampling rate of the programme we are using to record the signal, as this can be changed. Perhaps a program that can hog the settings of the mac in order to fix the sampling rate? I'm quite new to macs so bare with me please.
Our current setup consists of a MacBookPro3,1, 2.2GHz Intel Core 2 Due, running Mac OSX 10.6.8.
Many thanks
