The "maroon" data you are speaking of is the sound format. This is a cluster which must agree with the type of sound you are trying to record.
A few things you should know before trying to record a wave file:
The type of wave file must be known. This is either 8 bit mono, 8 bit stereo, 16 bit mono, or 16 bit stereo. You have a 2D array, which indicates stereo. The 8 or 16 bit selection is then a matter of the levels of your array (amplitude). If the values are in the range of -127 to 127, then you have an 8 bit array. If they are between -32687 and 32687, then you have a 16 bit array. If they are somewhere in between, you will have to scale them, otherwise, you risk the volume being too low.
In order to input your array, you have to convert
it to an integer. In the math palette, you will find a conversion sub palette. Just drop in a U8 or U16 between your array and the appropriate input, and you will be set.
Again, depending upon your data, you will need either 8 or 16 bit stereo, and you have to put that in the Sound Format cluster (constant). The bottom variable is for the sample rate, which again, depends on your data.
Good luck.
