Audio File - Specific frequency range filtering

[P3tson]

Hi! Im very noob in labview, i need help for my exam! The task is to do a audio filtering program in labview. Sorry about my bad english. 😕

here it is:

First thing: We must do a wav file with some noise then we need  to describe with some aspects:

-The noise's specific frequency range

- The wav file's specific frequency range

We need to with the program:

-Specific frequency range filtering ( with windowed -sinc)

- One input : the wav file

- One output: the filtered wav file

- Compare the filtering with the built in digital filters

( we can change the parameters in the front panel! )

Hello.

I suggest you to start with examples from Example Finder (in Labview go to Help>> Example Finder). There you can do a search for function you are interested in and figure out how those simple example are implemented. Combination of those examples will bring you result.

Functions which can be usefull for your task, you can find on Sound and Vibration subpalette (block diagram).

Links for examples, which explains how to use those functions, you can find in detailed help of those functions.

Do a serach how to write in wav file in LV, how create signals with specified features, how to add noice to signal, how to filter signals,...

I do not think that asking for a code, without trying firstly, is good aproach...Did you try to do your task by yourself?

Best regards, 

S.P.
