Simulink multimedia processing PSK modulation

A Music File Transmission with BPSK

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

Same error here... Did you got the solution?

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?
