You could read wav files in to LabVIEW using these VI's: http://zone.ni.com/reference/en-XX/help/371361H-01/lvpict/sfilevis/ Once you have read them, split the waveform in to frames of your choice.

i hav read the audio data from a wave file.. i just needed to split the data into frames. because only in shor duration the signal properties remains constant.. could u pls help me split the audio data into frames..

supposing i hav around 186500 samples i need to separate those samples into 20 or 25 frames to do my further processing...

What does your question have to do with this thread about audio signals. Please start a new thread with some details and the code you have.

hi i m doing project on activity detction module for ppg signal.In that I want to compute the energy profifile of ppg signal using kaiser teager operator from each frame and after that i want to calculate the mean,variance,interquartile range,skewness from the computed kaiser teager energy.could anyone plz anyone help me how to code this since i am new to labview i dont know the basic ideas regarding it.so plz help.......

hello, I'm sorry but I felt the need to express to you how useless answers like these are to people learning the program, and how people like you are the reason AI's like we have today are so important. To answer questions without stupid gatekeeping rules and impatient smart people who have nothing better to do than remind newbies of the rules and how little they know. Answer the question, or get a life.
