Convert stereo to mono, but with only left side

I have some mp3 files that are stereo, but I only want to hear the left. I know I can change the balance through System Preferences, but I want the left side to be coming through both speakers. Also I assume I could do this with Garageband, but there are a lot of files, and I'd rather not do that for all of them.
Thanks!

You don't want to hear the right channel at all or you want to combine both channels and listen to it with your left ear only?
You can convert the files to mono using iTunes.
iTunes prefs -> Advanced - Importing.
Click the drop down next to Setting and set it to Mono.
Now select the files you want to convert, then menu Advanced -> *Convert selection to...*
This will make a new copy of the selected files in Mono.
The original files will remain unchanged in iTunes.

How to make 1D Array but with only one element filled in Real Time

Hi folks,
here I am with another question. I want to implement an prediction discrete state space observer which is going to run on a CRIO real time target. I am going to do it just like in the example which comes with LV.
I have some questions regarding the input and outputs which in the example those are "dummy".
My model is a SISO model, but the function "Construct SS model" returns parameters (A,B,C,D Matrices) as 2D arrays, so once you connect the cluster model into the Discrete Observer model, it takes y and u as 1D arrays despite of the fact that there is a SISO model.
I realized that the function I am using in the simulations, uses 1D arrays but with only one element filled:
Does anyone knows how to implement such 1D arrays in Real Time? I guess the way to do it is preallocating one array of zeros of size 1, and then recirculating it through some SR, and replacing the element with my real input and output, but at the dummy.vi, they are using a simple "build array"
function.

Ok, I did it that way. But I am facing another problem right now...
At some point the Discrete Observer return a NAN array, you will see the code in the code snippet?
I get rid of that component by component, but the observer gets "stuck" in it. So my Control law is zero... but the state stimate is NAN.
Also I am attaching the VI.
I do not know why, since in the simulation program all runs well. any thoughts? Maybe the internal numeric precision of the State Space Model?

Late2012, RMBP. Only left side of earphone works.

When I plug in my earphone (iphone 5 earphone), only left side works, and Im sure this is a good earphone.
I used to adjust the banlance, and sometimes this works that both sides will work after my manual adjustment. However, now, this way wont fix the problem.
What's the problem here?

Recording mono, want to copy left side to right side for stereo

I've got a desktop studio and I can record only in mono, when I record in stereo it only records on the left track. is there a setting in soundtrack that I can change so the left track is coppied to the right track at recording???

Record in mono, not stereo. No need to copy from L to R channel in a stereo file. Mono will play in both channels...and you can pan it as you wish.
If you do record in stereo, simply double-click the track and convert it to mono (select L channel for conversion).

HT1473 Often times when I copy a CD into my library it breaks the CD into more than one Album, all with the same name but with only a few of the songs on each. This happens whenever the CD has music with more than one artists...like maybe duets.

Often times when I copy a CD into my library it will break my CD into multiple albums in my library, each with only a few songs.
Usually this is because there might be songs where the artists has other artists in the song.
How can I compile all of the different albums (all with the same name by the way) back into one as was the original disc?

Generally all you need to do is fill in an appropriate Album Artist. For more details see my article on Grouping Tracks Into Albums, in particular the topic One album, too many covers.

I'm also having this problem even thought it worked perfectly well before

do you think the apple store might take it in and fix it?

Sound out only left side.

I only get sound out of the left side of my headphones. I have all ready made sure the headphones are not broken (tested in another iPod Classic). I am fairly certain my iPod requires service, but figured I would check first. Also if someone could point me where I can go about setting up sending my iPod in it would be appreciated.

Hey there,
The problem could just be a bad contact, but sadly there really isn't anything you can do to resolve the problem.
If your iPod is still covered by its warranty consider setting up a mail-in repair for your iPod at http://depot.info.apple.com/ipod/
Or visit your local Apple Retail Store http://www.apple.com/retail/
Otherwise, if no warranty, there are numerous 3rd party businesses that will dianose the exact problem with the iPod and repair it. Just do a simple google search for "ipod repair parts" and you should recieve a plethora of sites that can help you. I would recommend doing a bit of looking around before choosing one.
Here are a few good ones.

I will have page open in the browser and when I click on one particular bookmark it always opens in the same browser but as a second page on the left side of the page. How do I stop this from happening--it is apage that I need to visit often for business and it is very restricting.

My macbook keeps freezing with the left side of the screen on the right and the right side of the screen on the left. Help

My 17-inch early 2011 macbook pro keeps freezing on me. The freeze usually occurs when I'm importing or exporting pictures, when I stream anything, or If I am watching a dvd. The left side of the screen shifts to the right and the right side of the screen shifts to the left. lines also appear on my screen and I can not force quit any open application. I have not dropped my laptop at all.
Mac OSX Lion version 10.7.5
2.2 Ghz Intel Core i7
I would like to avoid going to the an apple store to fix this problem if possible. The closest one to me is 40 miles away.
Help : )

If you don't have the Applecare extended warranty then you will need to pay for the fix. The fix is a New Logic Board. It seems as your Graphics card is failing in some way. No there is no software fix for this.
The Graphic chip is soldered to the logic board and the only way to change/fix it is to replace the complete logic board.

Lumia 925 only left side speaker working ?

Hi , im having a problem , i bought an used lumia 925 few months ago , and i didnt have any problems hardware wise except this..
When i play music i can hear it only through he left part of the speaker on the phone's back.
If i try and put my finger on the right side ,, nothing happens . If i cover he left side , i block all the sound output. Can someone tell me what should /could i do , on my own ? Thanks

Good day, arsaboss.
We understand where you're coming from. How's the phone doing? Did something happen to your phone that possibly cause such behavior? Any fixes you've tried like press and holding both the volume down & the power keys for 10 seconds or a reset under Settings> about> reset your phone?
When was the last time you updated your phone's software? Can you confirm that you have the latest one by checking if 'Lumia Cyan' is shown under Settings> extras+info? How about your system apps? See: http://discussions.nokia.com/t5/Pool-of-Knowledge/Nokia-Windows-Phone-8-App-Updates/td-p/1640082. By the way, where are you located?
Keep us posted.

Right side of track pad not working, only left side is working

the right side of the track pad on my MacBook Pro is not working, only the left side.

If this computer has a removable battery, take it out and see if the battery is swelling. If that is the case, try running the computer without the battery on just the charger, to check if the swelling is the cause.
If the computer does not have a removable battey, the best you can do is examine the underside for signs of a swelling battery.

How to convert stereo to mono?

First of all, I'm sorry if I'm posting in the wrong place, but I couldn't find any other sub-forum that was more appropriated.
I have a bunch of mp3 stereo files that I want to downsize. I'd like to make them mono and maybe lower their bitrate.
I'd like to know if there is a way to do that inside mac os X or if I have to use a specific software. If so, what soft do that better?
Thanks
Adriano

You can do it with iTunes. In its "General" preference, click "Import Settings", set "Import Using" to MP3 Encoder", set "Setting" to "Custom", set "Channels" to "Mono", and set the desired bit rate or quality.
Hold down Option and use "Convert to MP3" from the "Advanced" menu to select the files to convert. You can select multiple files using the Shift or Command keys.
The resulting files will be in the iTunes library. You can right-click and use
"Get Info" to find their location on the hard drive if you want to move them.

Warning for header po delivery cost but with only free of cost items

Dear.
Do you know If exist a chance to send a warning If I insert in a purchase order a header delivery cost condition type but the items of this po are only free of cost ?
Thanks.

Dear Chris,
As per my knowledge this cannot be done in standard SAP because
When we create PO line item with Free goods indicator set automatically item conditions tab correctly disappears
But the header condition tab always will be there because " In a PO you may have 6 line item out of them 3 is free goods and 3 is not " That is the reason Header conditions tab is there.
But you don't really have to worry because if you have only 1 item with Free goods indicator set and you enter a amount for header freight you will find the field condition value by default Blank and you cannot enter a value there , so no need to worry no postings will be made.
Now say you have PO with 3 line items (out of which1 with Free goods indicator) and you enter a header freight 100 EUR
You will find now that field condition value is not becoming blank and the amount 100 EUR is distributed among 2 non free Goods item proportionately.
Hope it clarifies

On opening, the browser comes up with not an address navigation bar, but with only two google search windows. How can I make it open with an actual address line?

It's all been said in the question.

Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: command+Shift+F).<br />
If you are in full screen mode then hover the mouse to the top to make the Navigation Toolbar and Tab bar appear.<br />
You can click the Maximize button at the top right to leave full screen mode or right click empty space on a toolbar and use "Exit Full Screen Mode" or press F11.
If the menu bar is hidden then press the F10 key or hold down the Alt key, that should make the menu bar appear.
Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"
