Re: OOT Module with shape error

The framework can give you different size input and output buffers. In this case, you would:

nitems = len(input_items[0])

out[:nitems] = input_items[0]

You may have to do more checks, of course, because input could be larger than output.

I am attempting to add an OOT module to my flowgraph. I have generated a General block which I want to place between an Audio Source and a Multiply Constant.

 

The Audio Source is set at a 48K sample rate. Input and Output are float.

 

As a test (I have never tried using an OOT module before) I said:

    out[:] = input_items[0]

in an attempt to simply feed the input to the output unmodified.

 

I get a run time error:

    ValueError: Could not broadcast input array from shape(4800) into shape(256)

 

Obviously I don't know how to perform the simplest possible operation. What is wrong here?

 

I have tried looking on forums and reading some of the GNU docs but no joy.

 

Thanks for any help.
