Error when recording vocal responses + playing a sound

Group: Forum Members Posts: 4, Visits: 4	Hello all, In my experiment I will be recording participants' vocalizations, which are cued by both a visual (picture) and auditory (beep sound) signal. I have coded this as follows: <trial 1> / stimulustimes = [0=image, beep] / beginresponsetime = 0 / trialduration = 3000 / validresponse = (anyresponse) / inputdevice = voicerecord / recorddata = true /responseinterrupt = trial </trial> <picture image> / items = ("image1.jpg") / size = (700, 700) </picture> <sound beep> /items = ("beep.wav") /playthrough = true </sound> The problem is that when I run this, I get an error: DirectSound Error -2004353017: Unknown DirectSound error.. Line 170, File win\SoundPlayer.cpp Recording vocal responses without playing a beep sound and vice versa is not a problem, but doing both simultaneously gives this error. Doe anyone perhaps know how to solve this issue? Thanks a lot in advance!

Doe anyone perhaps know how to solve this issue? Thanks a lot in advance! That DirectSound Error is indicative of a problem with the "beep.wav" file you are using. Specifically, the file probably has the wrong sample size (32bits). Windows DirectSound API (which the <sound> element maps to) expects files to have a sample size of 16bits. If you open said file in an audio editor of your choice and save explicitly save it as 16-bit PCM WAV, things should work fine. If you have trouble figuring out how to do this, put the WAV file in a ZIP archive and attach it to this thread (click +Insert -> Add File). I can then convert the file to 16-bit sample size for you.

Thanks a lot for this information! I managed to convert it into 16-bit PCM WAV myself and it works now!
