How to do an FFT on a WAV file ?

I would like to know what VI I should use
to do an FFT on a WAV file. Thank you.

You can use the "Snd read waveform" vi, located in the function palete:
Graphics & Sounds -> Sounds
to read the actual sound in the wave file. Then use the appropriate FFT vi in the signal processing menu.
there is an example provided with LabVIEW that can be of help to your effort. It is called "Simple Sound Spectrum Analyzer" and its description is that "Demonstrates how to acquire a waveform from a sound input device, window it, compute the autopower spectrum and the power and frequency of the peak frequency component."

  • How do I open a Quicktime created wav file in other sound editing software?

    A friend sent me three wav files created in QuickTime but they won't open in ANY sound editing software or players I have other than Quicktime. I need to use these for an upcoming podcast but can't do anything with them until I can open them with my editing software (WavPad Sound Editing).
    Can someone please tell me how to do this?

    On a Windows system you can't. There is a plugin codec for WMV for the Mac version of QuickTime, but not for Windows. You'll need to use other software.

  • How do you make itunes not play wav files?

    I know how to make it play wav files but how do I remove it from the default player list? I want them to all play in Quicktime. I have done the right click, holt alt and press Always Open With... and also done the right click and specify it to open in Quicktime. I have done this on 3 different Macs with 2 different OSX versions. It will open in Quicktime that one time but then the next time I open a wav file it goes back to Quicktime.
    Anyone have any suggestions?

    It will open in Quicktime that one time but then the next time I open a wav file it goes back to Quicktime.
    Do you mean, "goes back to iTunes"?  "A wav file," or the same wav file you just changed?
    Did you select the additional option in Get Info's Open With window to, "Change all of this kind to open with Quicktime"?

  • How to bounce or render a mono wav file?

    Hello all....this seems like a basic question, but I'm stumped. How do you bounce a stereo project to a mono (sum of both L and R) file? I switched the little "interlocking circles" symbol on the master output to a single circle, but that seems to move the summed audio to the L channel only, and then looking at the bounced file, it creates a stereo L + R channel, with the audio showing up on the L and a blank R channel. What I want is a single waveform containing both L + R audio, resulting in a balanced sound in L and R speakers. This should also result in half the file size of a stereo wav file the same length.
    Thanks in advance.

    Set the Stereo Outst to mono, then use the little bounce button underneath the fader to bounce. Using a bounce keycommand will always result in a stereo bounce. Using that little button will create a true mono file. If you have already inserted stereo Plugs on the Master Out this will not work, the Outs will remain stereo. So remove those plugs first.

  • Applying FFT decomposition to wav file

    Hi,
    I need to read a wav file and do a FFT decomposition on the same to change from time mode to frequency mode.After which I need to do a male-female transition of voice stream and change it back to Time mode.
    Can anyone please give me a idea.
    Should I use the JMF API of java.
    With regards

    I think you can use javasound for that purpose. I know someone had written a library that came with a book that implemented DSP.
    http://www.jsresources.org/faq_resources.html
    Just download the code from Craig Lindley's book. I could use it with a little modification. There is a FFT, pitch shifter and all the nifty stuff.

  • How to determine time value of a .wav file in real time as it plays?

    Hi all.
    I need to build a vi in which a .wav sound file is represented in a Waveform graph, and at the same time, I want to play that file, and have a vertical cursor line running along the Waveform graph, in order to have a visual representation of where the sound track is, in terms of time.
    Making the .wav file to appear graphicaly on a Waveform graph was an easy task to do, but then, I was´nt able to extract the time information of that .wav file, at the same time that this file is being played.
    This is a very common situation in music players, video players etc, where some kind of graphical artifact, represents in real time where the track is while it plays.

    Hi, this is the first ActiveX control I have played with but its really cool.
    I read this first: -
    http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmplay10/mmp_sdk/iwmpcontrolsinterface.asp
    Which covers "The IWMPControls interface provides a way to manipulate the playback of a media item."
    Then built the attached sample.
    It should now be straight forward to attach the position information shown to a graph control cursor postion.
    You will need to set a file of your own choosing in the VI first.
    Let us all know if this is what you wanted.

  • How to do a FFT tranformation for every file in a folder of another folder?

    Dear all,
    I have a folder A, there are seven folders in folder A, I call these seven folders B. and there are 100 files in every folder B. These files are all the data information of current.
    ok, now I need to transfer every current file into a FFT tranformation, and save the transferred files corresponding to the original file.
    Does anyone have some idea? Thank you for any help!
    Jing

    Hi Mike
    In this way, How can I save the transferred files as the same way as the original files and folders?
    after FFT transformation, I hope to get 100 files in every "transferred B" and seven "transferred B" folders in one "transferred A" folder.

  • How Do I Convert iTunes Songs to .wav files

    Is there any way to convert iTunes downloaded music to .wav format so they can be used in Adobe Photoshop?

    If your purchases are the new DRM free files from EMI, simply change your import preferences to mp3, then right click on the song you wish to convert, then click on "convert to".
    If the purchase is not one of the new files, you can burn your purchase to an audio CD, that audio CD can be used like any CD you might purchase at your local store.

  • How do I batch convert wav files to mp3?

    Just wondering how I can convert a batch of wav files into mp3 files (including metadata).
    I was looking thru features in both soundbooth and bridge, but I can't find it (if it exists).
    Thanls

    Found this FREE easy to use mp3 converter called All2Lame, here:
    http://members.home.nl/w.speek/all2lame.htm
    You will also need to download LAME MP3 encoder, and copy the lame.exe & the lame_enc.dll files into the all2lame directory to get it to work:
    http://www.rarewares.org/mp3-lame-bundle.php
    The program offers a lot of command line type options, so you need to read the documentation to understand all your choices, but here's a 'quickstart' line you can put into the 'switches' line that will make highest quality stereo mp3's using variable bit rate technique:
    --vbr-new -V 0 -q 0 --resample 44.1
    If you prefer mono to save space, use this line:
    --vbr-new -V 0 -q 0 -m m --resample 44.1

  • How can we convert .mov ( implemented by quicktime APi)  to .WAV file

    Hi,
    How can we convert one .MOV audio file (generated by quicktime API) to .WAV audio file ( need LINER - encoding format).
    Here I dont know the encoding format of .MOV audio input file.
    regards,
    Rams

    I wonder why this happens? The "unable to handle.." really does come out twice. Is it because the inputfile.mov which I wanna convert comes from the merging oftwo wave files? If so, then how can I convert this into single wave file? Thank you.That is a weird message, but yes, the .mov file probably stored the 2 original WAV files as 2 tracks of data, rather than 1 track. So whenever it's trying to transcode to a WAV file, it fails to transcode both tracks.
    As for fixing it... I dunno. I know that JavaSound can mix two WAV files at the sample-level, so it actually mixes the sound instead of adding 2 tracks to a file...but I don't know why that's giving you those error messages, unless perhaps it's trying to transcode the video track into an audio track (perhaps the code isn't smart enough to handle transcoding a video file into an audio file? You'd have to check the code to see if that's the case...)

  • How to create a .wav file in visual basic?

    I'm having the audio sample data(scaled data) in an array created by the CWAI_AcquiredData event. How do i convert this to a .wav file so that i can play back the audio data i acquired.
    Can any one help me out ????????

    Hello
    You should probably check out the MSDN for examples on how to do this.
    I think the Speech 5.1 SDK probably has some function that would help you out.

  • Read & Filter Multiple .wav files, Export Filtered SPL

    Hi
    I'm searching for tips on how to use LabVIEW to read multiple .wav files, then filter them, then export just the calculated SPL values to a "database friendly format".
    Basically I want a solution that allows me to point to several files, then press a "go button" that triggers LabVIEW to produce filtered SPL values as exported data.
    I'll skim over the cal approach since I'm confident most readers know how to handle it. Basically, though, for each 30 s .wav file of broadband noise, an associated cal tone file is used to determine the dBFS value (dB below Full Scale) to be associated with 94 dB SPL, or 114 dB SPL, as the case may be. I'll leave it at that.
    Detailed Requirements, (excluding cal steps, tho).
    1) Operates on up to a dozen 30 s time records (44,1 kSa/s, mono .wav files);
    2) Passes the signal from each desired .wav file through 18 of the 1/3 octave filters (IEC 1260 compliant, as in the S/V toolset) not necessarily in real time!;
    3) Calculates the SPL for each 1/3 octave filtered time record; This makes (12 files) x (18 filters) = 216 filtered SPL values if end-user points to a dozen broadband noise files before pressing the "Go" button;
    4) Exports SPL values in a suitable database format; an existing database does the rest of the mathematics and report generation;
    Client FileMaker database functions include:
    - import and store 1/3 octave filtered Leq(30) SPL values;
    - average filtered SPL across the declared qty of mic positions of the present test case;
    NOTES:
    1) In the field, we do NOT use simultaneous / MULTI-mics. Instead, it is absolutely an "open and shut case" that the optimum process is to move one (1) single mic quickly from spot to spot. While holding the airborne noise at a constant level we position the mic at each spot for 30 s to feed the .wav recorder, then move on. We emerge from a typical day of field activity with, say, 60 to 100 .wav files to post-process.
    2) (1), above, explains why we don't use any N.I. DAQ h/w.
    3) LabVIEW, it seems, exports best to a spreadsheet, so if needed, I'm prepared to handle manually any ugly conversion from LV's format to a proper database format ("1st Normal Form, 2nd Normal Form, etc.).
    4) Given a choice to calculate the averages in my database, versus in LV (say, to cut down on exported data qty), I'd likely opt to export the 216 SPL's and then do averaging in the database, (where the ASTM E336 reports are done).
    TIPS Gathered To Date:
    1) S/V toolset has IEC 1260 compliant filters, BUT...
    2) If you use the S/V toolset VI's, then you CANNOT ACCESS the filtered time record NOR CAN YOU WRITE the filtered data back to a .wav file! All you can do is measure the filters' outputs. Fortunately for us here, the available measures include SPL.
    Aside: Although not a show-stopper in this project, this constraint is surprising, nonetheless. To access & record the filtered sound, you'd have to either (a) ask N.I. to unprotect VI's, or (b) develop your own IEC compliant filters from N.I.'s published tap co-eff's etc.;
    3) LabVIEW does not support drag'n'drop operations on files. Instead, the recommended technique is to use multiple "Browse to/ Navigation/ File Open" panels to allow LV to open the user's desired qty of .wav files simultaneously;
    Thanks for any tips!

    The filter VI is password protected in the Sound & Vibration Toolkit (SVT) for two reasons. First, since the filter is compliant to a standard, by locking the code we guarantee that no one has the chance to accidentally change it so that they are no longer compliant. Second, the method of filtering the data is considered intellectual property that we are protecting.
    That said, from reading your post it does not appear that you need to have access to the filtered data since you are making an SPL measurement which is provided in the Sound & Vibration functionality. Is that correct?
    Also, I wanted to point you to another subVI which comes with SVT but is not in the pallette that might be of use. There is an example for SVT which is SVXMPL_Wav Power Spectrum which opens up a wav file and computes the power spectrum of it. Inside the VI, there is a subVI which will open a Wav file and convert it into a waveform which you can use with your SVT functions.
    Hope that helps,
    Jack
