From audio device puts out data by frame. Now my problem is how can I form each data into integrated singnal stream?

My friend, many thanks for your valuable reply.
Integrated signal stream means that each frame signal is saved in a variable and the variable will be processed.
If the frame signal is not saved in a variable, I will write each frame signal(10 s) into .mat file by To File and the data matrix size is 256x313. However, when the data is read from mat file by From file, only part of data can be read and the matrix size is 51x256. (The signal sampling is different). My problem is how can I read all the data, not part of data of the mat file?
I am looking forward to your answers and your suggestions. Thanks.

It's probably best if you don't accept your own answer.

It sounds like you are referring to the From Audio Device block from the Signal Processing Blockset. Yes, it outputs a frame-based signal. There are a number of advantages in using frame-based signals, particularly for signal processing applications. You might want to have a read of Working With Signals in the Signal Processing Blockset documentation. If that doesn't answer your question, you should probably clarify what you mean by an "integrated singnal stream".
HTH,
