Can you record sound using a USB 6211 and convert the data to a .wav (or other sound) file?

Hello,
I am trying to build a system that will use a USB 6211 to record sounds from multiple electret microphones and then save the data as a .wav file or other sound file. I have already built my mics and hooked the mics up to the USB 6211; the DAQ device seems to do an adequate job recording the signal - I've recorded from 3 mics at a time at 11,025 Hz, although I don't know how good the signals are since I can't save them for playback after the fact, and they aren't going through my sound card. Ultimately, I would like to save the data as a multichannel audio file which I could then open in a program such as Audacity for further editing and analysis. Since Audacity can import a variety of sound files, my file format doesn't need to be .wav if another format would work better.
Any advice would be appreciated.
Thanks, Eric

If you are sampling all three simultaneously, your highest frequency recordable will be (11,025/2)/3, so about 1800Hz and that will pretty coarse (traditionally digital sound recording is at 44Ks/s at the low end). As to converting to a .wav, there are functions on the "Graphics and Sound" palette for saving waveforms to a .wav file.

How can i re-enable/restore a disabled iPad and keep the data without using a laptop or iCloud

Hello,
Is there a way to re-enable a disabled iPad and maintain the data taking into consideration that no iCloud backup was made and the computer it was last synced with was not available? any idea?

No, sorry. Without a backup in iCloud or iTunes, you will have to set it up as if new and anything on it will be lost now.
You can always re-download purchased apps and content (other than audiobooks) once it is restored, from the respective iTunes or App stores.

Writing the file using Write to SGL and reading the data using Read from SGL

Hello Sir, I have a problem using the Write to SGL VI. When I am trying to write the captured data using DAQ board to a SGL file, I am unable to store the data as desired. There might be some problem with the VI which I am using to write the data to SGL file. I am not able to figure out the minor problem I am facing. I am attaching a zip file which contains five files.
1)      Acquire_Current_Binary_Exp.vi -> This is the VI which I used to store my data using Write to SGL file.
2)      Retrive_BINARY_Data.vi -> This is the VI which I used to Read from SGL file and plot it
3)      Binary_Capture -> This is the captured data using (1) which can be plotted using (2) and what I observed is the plot is different and also the time scare is not as expected.
4)      Unexpected_Graph.png is the unexpected graph when I am using Write to SGL and Read from SGL to store and retrieve the data.
5)      Expected_Graph.png -> This is the expected data format I supposed to get. I have obtained this plot when I have used write to LVM and read from LVM file to store and retrieve the data.
I tried a lot modifying the sub VI’s but it doesn’t work for me. What I think is I am doing some mistake while I am writing the data to SGL and Reading the data from SGL. Also, I don’t know the reason why my graph is not like (5) rather I am getting something like its in (4). Its totally different. You can also observe the difference between the time scale of (4) and (5).

The binary data file has no time axis information, it is pure y data. Only the LVM file contains information about t(0) and dt. Since you throw away this information before saving to the binary file, it cannot be retrieved.
Did you try wiring a 2 as suggested?

HT1473 I have songs in iTunes that were loaded from a CD. I want to make them MP3 format so I can use a converter to play MPe files in my wifes car. I plan to use a USB plugin and pass the songs through a cheap FM type converter. Don't want to spend hundr

I copied music from CDs into iTunes on my desktop. I downloaded a lot onto a USB stick. I want to play them in my wife's Toyota Avalon but I must use something like an FM converter and that requires all songs be in MP3 format. How can I reformat the CD songs into MP3 format? Not important enough to buy an iPod Nano!!

"but I must use something like an FM converter and that requires all songs be in MP3 format."
No it doesn't.
An FM converter takes audio and sends it over FM to the radio.
A USB stick does not play audio.
You need something to play the audio (like an iPod) and plug the audio out into the FM converter.

Can you record a video camera output over HDMI with the HDMI thunderbolt adapter on a Macbook Pro

I have an interesting question. I do video editing, and I know there are some new devices on the market, such as the black magic mini recorder that lets you go from HDMI to Thunerbolt. But can you not do the same with the minidisplay/thunderbolt to hdmi adapter, allowing you to record the uncompressed HDMI signal?

The answer to this question does not exist on the internet.

Can I stream videos using airplay to appletv2 and play the audio thru stereo using airport express?

I have apple tv 2 connected to my HDTV. I am streaming VEVO videos from iphone to ATV2. Would like to play the audio through my sony stereo. Would love to do it wirelessly if possible. Can this be done? Would airport express connected to stereo make this possible? If not what are my options.

The only input ports I have on the stereo is a dmport, auxillary and headphone jacks. I really would like to do this wireless. If, instead of appletv2, I had google tv which VEVO uses could the airport express be used? Seems like I recall reading somewhere that using 2 of them created a wireless connection for audio. Is that right?
Thanks for any advice.

Can you record video usb webcam

Can you record video using final cut pro from a usb webcam? you can do that with quicktime. Can you do that with final cut pro? i tried import video from camera but it only shows isight camera that is built in the macbook.

You can record live video from the built-in iSight camera that is standard in most macs (in fact, all but the Mac Pro and Mini). From other cameras, I doubt it. Of course, you can record with Quicktime Player and use the recorded video inside FCP X. But beware, many webcams have very low quality, low frame rate and size, so don't expect to get great video.

How do you record video with usb mic and have the audio from garageband be the sound when recording and not just your normal voice but garage band effects for youtube?

How do you record video with usb mic and have the audio form garageband be apart of the video when recording, meaning the audio from garageband and echo and not just your normal voice for youtube post?its not add the garageband audio its just normal voice from mic no effects is going thru?

Hi Life93,
What you describe would be possible by recording your video, then removing the audio from it and adding audio from GarageBand once the video is in iMovie (I presume here that you are using iMovie for your video production. Other applications may need different methods.)

Why can I no longer use my exterior speakers connected to the USB port on my MacBook pro

QuestionWhy can I no longer use my exterior speakers connected to the USB port on my MacBook pro ?

Have you checked the Sound Preferences under the System Preferences and set it to USB speaker for the sound output? Sometimes it can change on its own or after and update of an App or the OS?

!Can you record live while game playing with adobe audition? PLEASE HELP!

Can you record live while game playing with adobe audition? I have a youtube channel and I want to record voice as I'm playing of course and cancel out the noise maybe put a nice effect on it.. But how do I do this? Please help! I only see ones for recording like after.. But I want to record it as it's happening is this possible!? it has to be. thanks *ADOBE AUDITION CC*

That'll depend on the capabilities of the sound card/audio interface you're using. If that interface can feed the right things to Audition, it can record it. For just the game, look for "Wave Out" or "What U Hear" on the list of audio sources but not every system has this. Also, if you want to record your own contributions as well as the game sound, that gets more complex too.
I know that there are specialist pieces of software that are designed to record live gameplay (which don't rely simply on your local sound card). I know of a couple called "Action!" and "XSplite" but I have not personal experience with either.
However, before going that direction, check out the "Record Devices" menu in your sound system and see what it allows.

Did you buy your machine second-hand? That's really the only way you would have to purchase OS X 10.8.x from the App Store... but, yes, if you have a USB thumb drive with a bootable installer (such as made with Lion DiskMaker) you can boot from that and reinstall OS X.

Can you record your voice in logic pro 9 just as simple as garageband or do you need a plug-in?

can you record your voice in logic pro 9 just as simple as garageband or do you need a plug-in or interface?

Alas, poor Logic, I knew him well.
Recording wise, It will be much the same as Garageband but you will need to read manuals as Logic doesn't set things up for you. You must choose input and output devices, create the correct tracks. Logic was designed for professional use so it expects users to be somewhat familiar with recording/editing techniques, in other words, won't hold your hand or be nearly as easy to use.

Hi-Fi docking station...can you record onto the iPod...?

Hello iPod users.
I want a new Hi-Fi with an iPod docking station (these are readily available)anyhow, I know full well that you can play and control the iPod when it is on the docking station of a hi-fi, however, can you record or synchronise the iPod when it is on the hi-fi docking station?
In short, can you only put music onto an iPod by using a computer?
If not, can anyone suggest to Apple to make this possible?

Hi!
The only way you can get music on your iPod is to use a computer. There are some iPods that will support recording voice memos with an external microphone, but I don't think you can record directly from your Hi-Fi. Awhile ago, I looked into getting a device to digitize my long out of print recordings, but I gave up as more of those albums became available for digital download through iTunes or other (legal) sources. It proved to be less expensive, and less hassle than trying to re-record. Hope this helps!
