Convertion from FFT to waw

Hi everyone,

I had createed a labview application for grab my microphone audio using Bass.dll (http://www.un4seen.com/)

but i'm stuck .

I have useed this function

DWORD BASS_ChannelGetData(
    DWORD handle,
    void *buffer,
    DWORD length
);

The function works well.

I recieved a string data from  void *buffer , the data are a sample of FFT and I recieved a lenght data.

The problem is :

How is it possible to convert my FFT data in to a wav file .

Any Help or advice is much appreciated

Simone

Hi Simone,

Take a look at this documents that maybe can help you:

http://www.scribd.com/doc/15962724/Reading-and-Writing-Audio-Files-in-LabVIEW

 

http://cnx.org/content/m14771/latest/

 

Once you know how to convert raw (array of numbers) to wav, you can extrat this RAW data from FFT and do the job.

Let me know.

Eh...What are you trying to do? Your attempt to record sound is very awckward. Go to help in the toolbar. Then Find Examples. Search for sound. And use one of the examples as template for your project



Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)
