I am working on a project to visualize music in simulink. I'm trying to recreate the schematic presented in this video.
I use : #1 From multimedia file to open .wave audio file #2 lowpass filter #3 idealized 8bit ADC #4 Convert 2D to 1D #5 Delay line #6 Unbuffer #7 Generic LED
I get this 2 errors
Error in port widths or dimensions. Output port 1 of 'licenta_LED/Unbuffer' is a [1x2048] matrix.
Error in port widths or dimensions. Input port 1 of 'licenta_LED/Generic LED' is a one dimensional vector with 1 elements.
This means your LED block can take only scalar inputs while you are trying to send it a vector data. Unbuffer works on channels. You will get a scalar output from unbuffer for each column of data. You have 2048 columns. Try using reshape with output set to "Column vector (2-D)" instead of converting 2-D to 1-D. Your input to delay line and unbuffer should be a column vector.
Hi Mike , I am working on the same project . But I have a difficulty finding the required Low pass filter and specifying its parameters . Can you send me some information about the parameters and the blocks used.Thank you
