How to input Audio to W520
Much to my surprise, there is no audio input jack on the W520. I must have been dazzled by all of the good things about this laptop, not to notice there is no audio input. The big question is what is the best way to feed audio to the hard disk so that I can play or burn CDs from my collection.
The W520 only has a 4 pin headphone jack, which means you can get a microphone IN with an adapter. For line level input, you would have to use an attenuator with the MIC IN. Or you could get a better soundcard, e.g. an Indigo EpressCard:

Mac os x 10.9.2. ; Garageband 10.0.2There is no audio line input on your Mac, get a USB interface, get one that is specified for guitars.

I am wanting in input audio to a MacBook Pro running 10.9.4. Since there is only the internal microphone as an input choice, how do I accomplish this?
Not something I've ever done, but I found a 9-year-old article from MacWorld -> http://www.macworld.com/article/1041790/tapetocd.html - that explains it a bit. Apparently the only software that you need is GarageBand and a hardware interface. Just Google "copy audio cassette to mac" and you'll get tons of hits.
Good luck,

Running CS6 on a Macbook. Can anyone help me figure out how to record audio that is streaming on the Macbook? Under "Audio Hardware," my input choices are "Built in Mic" and "Built in Input." Neither does this.
Please repost on the CS6 part of the Audition Forums.

Up to how many inputs for audio recording.
just like the subject, up to how many inputs can be used for audio recordings at one time. i have four audio tracks but i could only arm 2 because i only have the choice for input 1 and 2. ive tried several things but cant seem to get any more inputs. is it possible to get more? if so can anyone help me. ive been told audio input objects but it didnt work.
Greetings! You don't say what audio hardware you have. If you have nothing other than your standard inputs on the MacBook, then you can't have more than two inputs. If you have a multi-input audio interface then it sounds as if it's not connected properly. Check:
Audio > Audio Hardware and Drivers
Make sure your audio interface is selected.
Also, click-hold on the I/O button for each track and make sure that you have selected different inputs - there should be one input listed for each physical input port on your audio interface.
If you're still having problems, you may need to delete your preferences and run Logic Set Assistant to rebuild your system - only takes a couple of minutes and worth doing.
Clangwork is also right about Audio MIDI Setup since Logic can only see what AMS tells it about.

Hi, I use Notion 4 like rewire slave in Logic, but I don ´t know, how to activate audio input from it, can anybody help me? Thanks, Mario
With the rewire slave running, create an aux track in Logic. You should see rewire as an option for the inputs of the aux track.

How to restore audio in iOS 8 (beta 5) after requesting mic access?
I posted this question over on StackOverflow before realizing that the AIR team might be working on a fix: http://stackoverflow.com/questions/25168882/air4-how-to-restore-audio-in-ios-8-beta-5-afte r-requesting-mic-access
In a nutshell, requesting microphone input in iOS 8 will terminate all audio if it's done AFTER a sound has already been played, but not if it occurs before (sample code is in SO post).
Apps were tested using an iPad 3 the Flex 4.6.0 SDK with AIR 4.0, and with AIR 14.0 - the same behaviour was exhibited.
This poses serious problems for our apps, which are already released and being updated for iOS 8, so please let me know if this is a known issue, and if not, whether you're able to confirm from your side.
Thanks!Yes, exactly the same flow on our side - interesting to know that it's FLV as well.
My problem remains, though: in iOS 8, if I play a sound (via MP3, SWF, etc) and then check the mic, all further sound in the application stops indefinitely until I close/reopen the app. Since we need to record audio at various times in the app, this will cause a major problem for our users!
I've added a bug in the hopes that someone can verify the problem: Bug#3801262 - Requesting microphone access in iOS 8 (beta 5) terminates all further audio
Thanks! -
How to input data into an arraylist from a text file?
I am trying to take data from a text file and put that data into an arraylist. First here is the text file:
[item1, 10, 125.0, item2, 10, 12.0, item3, 20, 158.0]
3
4530.0
[item5, 65, 555.5, item4, 29, 689.0]
2
56088.5
[item7, 84, 34.5, item6, 103, 0.5, item8, 85, 1.36]
3
3065.1The text between the [ ] is the output from my arraylists. I have three arraylists. The first [ ] belongs to arraylist A, the second to arraylist B, and the third to arraylist C. The format of the arraylists is this:
<item name>,<# in stock>,<value of one item>
The first number below the arraylists in the text file represents the number of items in the list. The second number below the arraylists represents the total value of the items in the arraylists.
Here is the class file I have (yes, it does everything):

Macbook pro to HDTV, video is working but audio is not working, how to make audio work as well
If you use an HDMI cable, the audiostream will be integrated, so there will be sound when using an HDMI cable!
Not necessarily. That only works as stated if you have one of the most recent MBP's that has a built-in HDMI port.
If the MBP only has a Thunderbolt or miniDisplayPort, you need an appropriate adapter cable and even if you use an HDMI adapter or cable to connect to your HDTV there is no guarantee it will carry audio. You have to determine if your specific MBP model supports audio out through its miniDisplayPort or Thunderbolt output, and whether the adapter does likewise. -

How to Input Value in ALV report at reuntime...?
Dear All,
How to Input Value or change the value of a field in ALV report at runtime...?

To input value in ALV you have to make it editable.
to change values at runtime you have to capture some events and then change your values in internal table which is used to display alv.

How to stream audio in Windows Phone 8.1?
I have a Windows Phone Silverlight 8.0 app I want to update to 8.1 using WinRT. It streams audio in the background. In Silverlight, I used
BackgroundAudioPlayer to set the Track to a Uri. It's not clear how to do this with
MediaPlayer in WinRT. I don't think I can just use a Uri. Instead, I wonder if I have to use
MediaPlayer.SetStreamSource(IRandomAccessStream
stream). If so, I don't know how to get an IRandomAccessStream from a
Uri. I want to stream from a Uri on the internet over HTTP, not from a local file. Any help?Refer following links to stream audio in background in Windows Phone 8.1 Runtime app.

Thank you for thinking about my problem. I may be mistaken, but I think the above links refer to Windows 8 apps, not Windows
Phone 8.1 apps. I'm under the impression that background audio is done differently in Windows Phone 8.1 from Windows 8. The
Background Audio Overview for Windows Phone Store apps explains more.
It's a good overview, but does not explain how to play audio from a stream rather than a file. That's what I'm stuck on. -
