Recording voice RT (case 34074)

    Recording voice RT (case 34074)

    I have set up an experiment in DirectRt where I record audio responses. Although the computer is set to record sound at 44100 Hz, 16-bit resolution in the system sound settings, the recording I get from Direct RT is 22050 Hz, 8-bit. 22050 Hz is fine but not 8-bit, which is quite noisy. How can I set this to 16-bit? This is not a system limitation because using Audacity and other audio recording software, I can record at 16 bits using the same microphone and USB sound card. Thanks for your help.

    Unfortunately, it's not currently an option to set the recording quality. DirectRT records at this rate because when I wrote that code, I needed to pick a fixed rate to allow for the various analysis algorithms that were required--like assessing reaction times and such. I chose this lower rate because of the reduced impact that would have on processing. Not the answer you want to hear, I'm sure. It's certainly possible that offering a choice of recording qualities could be added in the future, it's just not an option now.

    Best,
