timetable to wav file

I am working with my sound files as timetables, but I need to convert them back to wav format when I'm done editing/analyzing. I can't convert directly using audiowrite, so I think I need to convert my timetable first?

I never did anything similar, so this is simply the approach I’d try first.

Perhaps first timetable2table then table2array, then save the matrix as a .wav file would work.

This does not work. The file created by table2array is of type 'duration'. I am not sure why.

I think I have to extract the data from the file?

>> A = timetable2table(NMP_tt);

>> B = table2array(A);

>> audiowrite('C.wav',B,fs)

Error using audiowrite

The value of 'y' is invalid. Expected input to be one of these types:

uint8, int16, int32, single, double

Instead its type was duration.

I think this works:

To write timetable 'B' to wav file 'C.wav'

>> audiowrite('C.wav',B.data,fs)

[Star Strider]

The array created by table2array should simply be a numeric array. If it has an associated time vector with it, extract the column or columns that are not duration arrays, then save them.

If saving the timetable directly from the .wav file works, then go with it.
