Using 'From Multimedia File', how to split the channels
显示 更早的评论
When using the 'From Multimedia File' and a stereo audio file in simulink, how can you take the output of the block and split into two matrices. (eg. output is 256x2 and is split into two matrices of 256x1). My last resort would be to load the file first into a workspace and then get the matrix from there, but I would like to avoid that
What I have tried and didnt work: Demux Direct lookup table Matrix Multiply
Any way to do this?
thanks J

Hello, I have a similar problem, where I need to seperate a stereo signal into two monos each with a size of 1024. Thank for for your explanaition, it saved me precious time rearching fro the right answer. It can also basically be considered a matrix 1024*2. Now the problem that have is dispaying the seperate sinals in each scope. I get this warning and even after waiting a lot the signal is not right. what sould i do and what settings have to be set right ? Thanks you.

Demux only works with vectors, but this signal is a matrix. You can use two Selector blocks. Set the input dimensions to 2, select all from the first index and 1 from the second index for the first block, 2 for the second block.
