Re: Sound recording problems with 2 microphones

[David McFarlane]

I am a bit confused. Did you follow the video exactly first and get
SoundIn to work, only to have it fail when you tried combining SoundIn
with the SRBox for RT? Or did you go right to writing a program that
tried to do both, skipping the first step?

If it were me, I would start by making the simplest possible program
that did nothing more than use SoundIn, and get that to work all by
itself. To that end I might follow the video to make my demo, or/and
download the already written "SoundIn Scoring" example from PST.

(BTW, I include an exercise on SoundIn in my online E-Prime 2 course,
but I do not combine that with the SRBox.)

Use a Slide object to present your stimulus, and include a SlideSoundIn
subobject on the Slide to record the sound at the same time.

To get a SlideSoundIn to work on a Slide I do the following:

- Set Buffer Size to how long I want the recording to run.

- Set Stop After to "No" if I want to keep recording after the Slide
object itself times out, set to "Yes" if I want the recording to end
when the Slide object times out (this does not affect the length of the
recording file, only how much of the file ends up actually containing
your recording).

- If I set Stop After to "Yes", set Stop After Mode to "NextOnsetTime",
unless I really need "OffsetTime" & understand why. None of this
matters if Stop After is set to "No". Probably best just to leave this
at "NextOnsetTime" unless you know better.

- Set End Capture to "(none)", "Terminate", or "Jump" depending on what
I want the program to do when the recording reaches its end; typically,
I would choose "(none)".

This has worked fine for me.

Now to combine this with sound RT, I would do the following:

1) Make the simplest program possible that simply uses a Slide &
SlideSoundIn to present a stimulus & record sound. Make sure that this
works and that I understand its operation.

2) Add an input mask to the Slide, probably using a Keyboard. Set the
End Action of the input mask to "(none)" in order to allow the recording
to continue after the response.

3) Add an SRBox device, and add that as an input mask to the Slide;
again, set End Action to "(none)" (remember that each input mask has its
own setting for End Action, etc.!). Set Allowable to "{ANY}", and use
the SRBox buttons to submit responses. Make sure that this all works as
desired.

4) Now plug the second microphone into the SRBox. The voice key acts as
button 6 on the SRBox. With Allowable set to "{ANY}", you should still
get responses using the buttons as well as with sound in the microphone
(and if you left the Keyboard input mask in place you could still use
that as well). Make sure that this all works as desired.

So just work up to this step by step, starting with simple components
that work and then combining them.
