I encounter error when trying part II from the link above. I only use a little part of the example that consists of From Multimedia File, Integer to Bit Converter, Bit to Integer converter and To Audio Device block.
I follow the parameters mentioned in the link but the following error occur:
Error in 'untitled/Integer to Bit Converter': Inputs must be integers in the range 0 to (2^(NBIT) - 1). To use signed integer inputs, set the 'Treat input values as' parameter to 'Signed'.
Details of block parameters:
From Multimedia File
- Inherit sample time from file - Checked
- Samples per audio channel: 1024, Framed based
Integer to Bit converter
- M=16, unsigned, MSB first, double
Bit to Integer converter:
- M=16, unsigned, MSB first, int16

I had the same problem but I solved it, I already had in int16 with uint16 I put all with int16 and it is solved

Got it. Try to reduce the interval of "Read Range" on the "From Multimedia File" block. Try to use [1 5000] or less. It worked for me.

Error in 'untitled/Integer to Bit Converter': Inputs must be integers in the range 0 to (2^(NBIT) - 1). To use signed integer inputs, set the 'Treat input values as' parameter to 'Signed' How to solve this problem?
