Best way to launch a large audio file

I have a 90Mb wav file that I would like to play via LV. I have looked at the examples in LV and understand how to play the wave file. Unfortunately, even when the file is done, my system performance is way down. This does not happen when I use the standard windows players. Is there a way that I can launch the standard windows player from inside labview? and have it play this file?

Hi,
If you are in a Windows only environment you can use a direct call to the Windows SDK to play the file for you. This way you let the OS handle the buffers.
The function is called PlaySound(...) I've included a small VI here for you to test it. I have not used it with large files, but windows should have no performance issues.
Let me know how this goes.

  • Best way to send a large sound file via e-mail?

    Hello,
    I created a sound file in Sound Studio that is 75.5 MB large. I want to e-mail it to a friend through my Hotmail account. (I have a cable connection. I do not have AOL. And I just discovered that I can play it on my computer using QuickTime.)
    What is the best way to do this? Do I need to compress it? I have heard of compressing large files to make it easy to e-mail, but I don't know how to do it. If so, will he be able to hear it when he opens up the e-mail on his end?
    If anyone could give me step-by-step instructions on how to send this, I'd be most grateful. Thank you.

    If you have Stuffit Expander check inside the folder for Drop Stuff.
    Drop the movie file onto Drop Stuff.
    This will compress the music file.
    Or
    You can send large music files through You Send It which is FREE!
    There are others but, You Send It is the easiest.
    Or
    Since you have a High-speed connection, the easiest & fastest way is through AIM (AOL Instant Messenger). You do not need to be a member of AOL.
    I send all my music & movie files this way instead of using email.
    iChat has the same ability of transferring large files as AIM.

  • What is the best way to manage the large FinalCutProX files

    We are continously running out of space on our desktop with the FinalCutProX files being so large. We have moved most of the files (events & projects) to an external server and working off the single video projects from our desktop. How are you working and what is you set up to manage these large files.?
    Computers we are using  new Mac Pro:
    Memory  16 GB 1600 MHz DDR3
    Processor  2.7 GHz Intel Core i7
    OS X 10.8.5
    What type of external servers?
    Are both the events and projects stored  together
    Do you keep the video you are currently working on your desktop?
    Thanks,
    Ang

    I have a MacBook Pro 17", 2.2 Ghz i7, 16 GB of RAM, 960 GB internal SSD (2 platters RAID 0). I have about 250 GB free on the internal drive, where I keep my current project. I also have a 3 TB external Thunderbolt desktop drive where I store the completed projects. I backup both drives to multiple drives that are stored away between daily backups.
    If my current project takes up a lot of space, I work it on the 3 TB external. I also have a 750 GB Seagate Momentus XT hybrid HD/SSD Thunderbolt bus powered portable just in case I need it in the field.

  • What is the best way of compressing a large 3 hour final cut file

    What is the best way of compressing a large 3 hour final cut file. I shot the play and it is in final cut and I rndered it so now I have a 22gb file that I need to put on a dvd . Any suggestions
    Thanks

    Presuming your menus aren't complicated(include audio or video) the total size for the MPG-2 and AC3 files should probably be under 8GB for a dual layer disk. The inspector will tell you the estimated size. 2-pass varible bit rate would be recommended.
    Trying to fit 3 hours on a DVD-5 will only bring very noticable quality hits. Compressor will let you change the average bit rate so that you can fit 174 minutes but trade-off isn't worth it in my opinion.
    Be aware that dual-layer -R and +R media may not play well for everyone everywhere.
    I presume you are not making 1000 or more copies? If you were replication could solve this.
    One other alternative would be to break-up the show into two parts and spread it across two DVD-5s.

  • Best way to organize a large photo library on a 10.6.8 Macbook?

    I have an older Macbook pro- version 10.6.8. 
    I am looking for the best way to organize my large library of photos (approx. 15,000).  I have both personal as well as professional photos that I would like to organize and keep separately. I currently use iPhoto'09 version 8.1.2 but it has become very slow and I would like to find a solution that uses better organization.  I am considering keeping my personal photos in iPhoto and my professional photos in another organization app.  I was thinking about purchasing Aperture, however it is only available for Mac OS X version 10.7.5 or later and the same goes for the latest version of iPhoto. 
    I am a little confused about what my options are.  Can anyone recommend anything?  I am looking simply for a good organization tool, I am not interested in photo editing or anything beyond that.

    Well now we know that the speed problem is in your old library. Repair it.
    Option 1
    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
    If that fails:
    Option 2
    Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
    This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. 
    Backing Up:
    Time machine will back up, yes. Just be sure it's set up correctly.
    Most Simple Back Up
    Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
    Slightly more complex:
    Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically. Examples of such apps: Chronosync or DejaVu . But are many others. Search on MacUpdate

  • Any way to export just an audio file?

    Hi All
    Is there any way to copy part of a larger audio file, paste it in another track (or open it in the file editor) process it in some way and then export just that file? Been reading manual and books, but this one has me stumped. Only see tracks and busses for export.
    Thanks
    John

    If anyone is interested, and it seems not, a helpful person another list answered my question: copy snippet from one file onto another track; solo new track; select just snippet; save. Finally I can add time-based effects to parts of a larger audio file!

  • What is the best way to deal with different audio sample rates on the same timeline ?

    what is the best way to deal with different audio sample rates on the same timeline ?

    You don't have to do anything special. If possible, start your project with a clip that has the desired target frame rate and audio sample rate, and your project parameters will be set automatically. Other sample rates will be converted under the covers.
    For example, if your video is shot at 48khz, you can add music files at 44.1khz with no problem.
    If you are recording audio that you want to synch with video (multicam), you will get best results if everything is 48khz, but you can use 44.1 if that is all you have. Once I forgot to reset my Zoom to 48,000 and it still worked.

  • Best way to upload a large 25 minute video and where to?

    best way to upload a large 25 minute video and where to?

    Just a couple minutes surfing - YouTube only allows 15 minute videos from general users -- to upload larger apparently you have to be a trusted long time source.   There is also a restriction on the file size.
    YouTubes help section should give you all the details.
    I don't watch online videos - so I just used a query in ASK.Com to get some quick tips.

  • Cut large audio file by duration

    ok so what i am trying to do is take a large audio file, over 6 hours, and cut it down into many 10-15min files.  i know i could manually just cut out what i dont want then save as a new mp3 a lot of times, but is there a way to set audition to do this automatically?  i cant seem to find a way.

    Now that you've placed the markers, can't you just swap the audio file in the multitrack project and reuse the same markers?
    If that's no good, I used Audacity (a free program) to do this recently : http://audacity.sourceforge.net/
    load up your file,
    create a text file in the simple format
    seconds <tab> marker name, e.g. for 10 minute files:
    0  marker 1
    600  marker 2
    1200  marker 3
    1800  marker 4
    Then in audacity go project > import labels, File > export multiple.
    The issue you might have is using mp3's in audacity. If you do want to use it, there's a solution here:
    http://audacity.sourceforge.net/help/faq?s=install&i=lame-mp3
    or you could convert to wave before cutting the files up (but that would be a big old file, and I'm not sure how well it would be handled)

  • Best ways to view/display PDF/Excel files stored in the Database

    What are best ways to display/view PDF/Excel files stored in the Database? thanks L

    Thanks tom, sorry let me explain. Currently we have oracle forms screen, using webutil to store/view files into DB. client won't like the interface, they want us to make it more friendly, drag and drop if possible, load multiple files, as possible.. So I am exploring different ways to improve may be java (or jdev/any any other), different screen designs, different features for fileupload/download/view options.

  • What is the best way to export a .csv/.txt file to a MS Windows shared folder via a scheduled job?

    What is the best way to export a .csv/.txt file to a MS Windows shared folder, when the export process is a scheduled job?

    You can't directly, as scheduled jobs can only export to server-side data stores, which can only write to the landing area. You'll need to use an external script (e.g. batch file) to move the file from the landingarea after export. You can use an external task in the scheduled job to invoke the script.

    None that I'm aware of but with the iPhone SDK - software developers kit being released at the end of next month, a 3rd party software developer may provide an avenue for this function and you can leave Apple feedback about this here.

  • How to move large audio files to deskop from iPhone?

    How can I move large audio files from my iPhone 4S (IOS7) to my iMac (OSX 10.5.8)?
    I can not use:
    - iTunes (will not install high enough to this ol'mac to work with IOS7)
    - cloud-servers
    - email, iPhone will not mail that big files...
    - image transfer program (will not work with audio files)...
    - etc.
    Is there any cable that will work? Can I modify my iPhone? Is it possible to move back from iOS7 to iOS6?
    This is kind of a big issue for me because I make long interviews with my iPhone but now I do not know how to move the files from my iPhone to my iMac for editing and pubishing.
    All ideas are welcome (except buy a new iMac)! Thanks in advace!

    You cannot use the iPhone unless you have the previous owners AppleID & password.

    Sounds like you need to change your process when you buy used iPhones.

    Is converting the colorspace asking for trouble?  Very possibly!  If you were to do that to a PDF that was going to be used in the print industry, they'd shoot you!  On the other hand, if the PDF was going online or on a mobile device – they might not care.   And if the PDF complies with one of the ISO subset standards, such as PDF/X or PDF/A, then you have other rules in play.  In general, such things are a user preference/setting/choice.
    On the larger question – there are MANY MANY ways to approach PDF optimization.  Compression of image data is just one of them.   And then within that single category, as you can see, there are various approaches to the problem.  If you extend your investigation to other tools such as PDF Enhancer, you'd see even other ways to do this as well.
    As with the first comment, there is no "always right" answer.  It's entirely dependent on the user's use case for the PDF, requirements of additional standard, and the user's needs.
