Macbook Pro: Play and record sound at the same time

Greetings everyone,
My brother and I have are going to switch go a mac, preferebly to a macbook pro. we used windows so far, but the frustration has grown extremely huge, so it's time to throw off this junk.
We've been working with sound a lot and many times we recorded any sound which played through the computer: that means sound and music from dvds and games or other sources, we couldn't get anywhere else. What we did is simply letting the game or dvd play and record the audio at the same time.
I've testet this functionality in windows via bootcamp on a macbook of friend of mine, but NOT the macbook pro version. It's wasn't really that good as I thought. Sound quality was below what I'd expect.
So here are my questions:
- Does the macbook pro have a better sound card, which enables simultaneos play + record?
- Is good record quality bound to a software I need to use?
Thanks for your replies.

Apple don't have separate "sound cards" like PC's , Martin. The necessary hardware is proprietary , and built into the logic boards.
Both of them have high quality combined optical digital input and audio line in, and combined optical digital output and audio line out. You can also attach various USB or firewire audio input and output devices if you wish. So as far as 'quality" goes, it depends what you are playing them through more than anything else. The inherent audio abilities of both are pretty danged good when using Mac specific software. That is why the music industry love 'em!
Or are you just talking about sound quality through the built in speakers, which are, of course severely limited by the amount of space available, though I've heard far worse from many PC notebooks!?

Can Express 9 play and record multiple instruments at the same time?

I have logic express 9 and was told with my interface that I can play and record different instruments at the same time on Express 9. Is this true because I have spent a long time trying to figure out how.

Hi,
to record multiple Inputs at a time, open up the appropriate number of audio tracks. Now for each track, select the correct Input in the Channelstrip.
Now, ARM all these tracks for recording by clicking the little red R in the track header or channelstrip. Now if you hit record, all these tracks should record simultaneously their respective inputs.
All other existing tracks should playback while recording.

Can I play and record minecraft on a mac pro

I am currently playing minecraft on a windows pc with a 1GB graphics card. My graphics card has crashed while playing basic minecraft. I want to buy minecraft so I can do more and also install HD resource packs, but are unable to because of my computer. I have been advised to buy the new Apple Mac Pro, as it has a 6GB graphics card, but am wondering if minecraft will run on it and if so, how well. I also want to record minecraft and put it on youtube, but have noticed that most of the people who play minecraft have pc's to play and record it on. I have also noticed that mojang, who make minecraft are using pc's. Is there anybody who is using an Apple to play and record minecraft and if so, could you let me know how well it works and if you have uploaded it to youtube, please give me your link or username. I am looking at buying the new Mac Pro to run minecraft but am wondering if it will do what I want it to do and if anyone has any advise.
Thankyou.

You can only PLAY Blu-ray discs on a Mac by using one of several software's that untilize a Blu-ray license on the internet. What this means is that you must have a fast internet connection to play the disc on your machine. Apple refuses in support Blu-ray with their OS, so there's no way one can play BRD using their computers software in a stand-a-lone manner, like Windows users can. This is one of those reasons for the love and hate relationships Apple creates for controlling the market to their advantage, at a loss of one of the most common entertainment formats to their user base. They could easily support the format, they simply chose not to either out of stubborness or for money reasons. The latter makes you winder when they have so much of it now.
Toast software, on the other hand, has the ability to burn Blu-ray discs, so you can at least use BRD for back-up. You can also rip movies, etc. I purchased a small and nifty portable BR burner from Sony, Model BDX-S600U that was fairly cheap at the time for $149. It's now $178 at Amazon. It only interfaces witha computer through dual USB though (one is for additonal power), so you can't use it with your TV. I use this device on my MacBook Air when I want to burn or play DVD's. I have tested the machine and it plays DVD movies and burns just fine. I've been so busy though, that I haven't actualy burned a BR data disc yet, but I know the Toast software supports it. Moreover, hard drives have become so cheap, that burning to BR isn't the best BU, but still uasable and great for mailing large files.
Unfortunately, until Apple gets their HOOTA we may never see BR support because Tim Cook may just follow Steve Jobs lead out of respect. Yet, with new leadership, and Steve out of the way (Bless him), we may eventually see Apple support. Especially as they continue to merge iOS and OSX. I wouldn't hold your breath on it though.

How to code a button to play and pause sound using load sound?

how to code a button to play and pause sound using load sound?I have used load sound methos to attach the sound.Can anyone help me?

Simultaneously Play and Record.

Hi
I'm working on a application where I need simultaneously Play and Record.
I followed the code of 'SpeakHere'. I got some success also. It is playing and recording simultaneously, but the problem is it plays audio through headphone speaker while recording. I wanted it to play through external speaker.
thanks.

That is, literally, all the code I have behind my "Enable Speaker" button. Are you sure you've set the Audio Session's category beforehand, and enabled it?
I see you're using the SpeakHere sample code. It does take care of setting up the audio session and enabling it. But it uses the "Media Playback" category of the audio session, rather than the "Play and Record" category.
Look for all the places in SpeakHere where they set the audio session's category (for playback) and change it to the "Play and Record" category. The property I mentioned above only takes effect in this category.
Good luck! If you're still having trouble, a chunk of code or some NSLog output might be helpful.

Play and record simultaniously

is it possible to play a song in a app and record video and/or sound within a app at the same time in a windows phone app? it works in windows 8 and since windows phone 8 has similar device capabilities I was wondering if it is possible.

Hello
When I first read your post, I couldn't believe it is possible to achieve without using C++ and WASAPI stuff. I immediatealy implemented it and launched on the emulator. I was really amazed how perfectly it worked (on the emulator). That was exactly
the behavior I wanted and tried to implement in various ways for more than 4 months for now.
Unfortunately, when I deployed it to the device I found out some imperfections that couldn't have been experienced on emulator.
First, the music was playing from this quiet speaker used for regular phone calls (the one above the screen). The sound quality is poor, quiet and - which is more important - the volume up and down hardware buttons control the In-voice volume (10 possible
settings) rather than Multimedia/apps one (30 possible settings). Even when I connected the headphones, the maximum sound volume was not even close to the one I could achieve using Multimedia/apps volume control.
Second, the music playback stutters. I first though the phone is just overloaded with simultaneous music playback and video recording (with preview enabled), so I totally disabled the video preview and recording. Unfortunately, the audio playback still frequently
stuttered. I found it always does when mediaElement.AudioCategory is set to Communications, no matter if video recording is on.
Trying to fix out the first issue, I used both
mediaElement.AudioDeviceType = AudioDeviceType.Multimedia;
and
mediaElement.AudioDeviceType = AudioDeviceType.Console;
with no results. The music still played only from this phone call speaker above the screen. Then I tried using all the possible AudioCategories enumerations. Any other than Communications blocks simulataneous video recording, so I didn't use them.
To try to fix the second issue, I used
mediaElement.RealTimePlayback = true;
but the playback still stutters :(.
Is it possible to solve at least the second issue with the stuttering playback? It is unacceptable in my scenario to have the playback interrupted in any way. It is strange since the phone is not overloaded and the stuttering is not present when the AudioCategory
is set to any other value. Or when the application is launched on the emulator...
Many thanks in advance and Happy Easter :)

Playing and Recording while minimized

I've noticed that Adobe Audition 3.0 will stop recording or playing when I open another window, or if I minimize it
I looked this up in the forums, and found a solution of unchecking the "Release ASIO driver in background" button. I've tried that, but the problem is persisting.
I've noticed that this is happening on two different computers, on the same edition. Is there anything else I should be trying here?

Need to play and stop sound file with 1 ms resolution

Hi,
I'm trying to open a .wav file then later play it at a time when another parallel loop activates a boolean local variable which controls playback in my "sound" loop. I need high time resolution in stopping the playing of the .wav file, ~1ms. From what I've gathered, I can't use the "sound output write.vi" because it locks the loop until it finishes outputting a set number of samples. Because of this, "sound output stop.vi" has to wait until the next iteration, which is more than ~1 ms.
In the help menu of the Sound Ouput VIs it says you can set the task ID for the "sound output start.vi" using the "sound output configure.vi." Unfortunately I've only been able to use the "sound output start.vi" following "play sound file.vi", and I don't really know why this is the case.
I can't start my sound with the "play sound file.vi" because it locks the loop its in until it finishes playing the sound. Oddly this only happens when there is a parallel loop running, if I run it by itself, with no other loops, it doesn't lock the loop. I thought it might have something to do with the local variable, but the loop doesn't lock when the loop restarts the sound using the "sound output start.vi."
After opening a .wav file, can i use the "sound output configure.vi" to create a task ID for the "sound output start.vi" to work? Or do I have to use the "sound output write.vi" after calling the "sound output configure.vi." The help menu makes it seem like the prior suggestion is possible.
Thanks a lot!

Since it sounds like the problem you're running into is getting the data loaded from the file before you're ready to play it, look at the Files sub-palette, specifically the Sound File Read Simple VI. You can use this VI to load the data into a waveform and have it ready for use later in the program.
So in your overall program, read the file with Sound File Read Simple and configure the output with Sound Output Configure and call Sound Output Write when you're ready to play the waveform.

How to listen to music and record sound at the same time

I want to figure out a way to record sound and listen to my music at the same time. Most recording apps stop my music when it starts to record and I can't find an app that does both. Any ideas?

Not possible since the iPod only has one audio processor.

Latence while playing and recording (Axiom 49)

Hello,
When i try to play with my Axiom 49 while playing a song or while trying to record myself, there is lag and I need to wait a little time before hearing the sound of my instrument. Also i need to press the key a certain time before i can hear the sound.
My keyboard is plugged directly in my MacBook Pro, the problem is not coming from the computer, i think there something to do in Logic but i don't know what to do .
Is there any way to change this ?
Pierre

Hello,
I found a solution, a complete reinstallation of Logic solve the problem.

Unable to view Play and records buttons

I am unable to view the bar with play, record, stop etc.

Just position your cursor on the bottom edge of the Arrange window until your cursor appears as a solid black line with an arrow pointing up from the middle. Then either double-click or click and drag up until the Transport appears. You can also open the Transport in a separate window using CMD+7 or going to Window/Transport.

Youtube videos do not play and gchat sounds do not work

These problems are only in Firefox. Allow me to elaborate.
I have a Windows 7 64-bit laptop, Firefox 13.0 and the latest Adobe Flash Player installed. What's strange is that I think the videos worked fine two or three days ago, but now the videos don't work. I thought this was a minor glitch, then I noticed that I wasn't getting chat notification sounds on gchat in Firefox. So I went in the settings and it said that sounds were linked to Flash player. I looked up Flash player and installed the latest one, still no change. I then uninstalled flash player and reinstalled. Still, no dice.
The youtube video problem is rather strange; I've never seen it before. The black box appears, and below it are the normal volume controls, video controls, play, etc. Inside the black box is the play button, with the white triangle in a red box pointing to the right. Like I said, I've never seen this before, so I decided to click it since my videos weren't playing. I click it, and all I get is "An error occurred. Please try again later". I do the normal clear cache/cookies, restart browser, still no dice.
Everything works fine in google chrome. It's just firefox that's giving me these problems. If anyone has suggestions, please let me know!
Thanks in advance.
Edit: oh, and on the adobe page where you can test to see if your adobe flash player is working, all I get is blank spaces where the video or animation is supposed to be. Facebook sounds seem to work too. But in Tetris battle, I get "Errors on Loading File: Facebookmainframe.swf. Retry..."

I too have the same issue with Firefox and flash videos. I haven't tried to use other browser yet, but I will when I finish this. I first saw this yesterday with Firefox 12.0; same issue with FF 13.0 now. No video anywhere will play, from YouTube to TMZ! I either get an error "error occurred try again later", or the area on the page where the video should be is blank. I have uninstalled and reinstalled all Adobe items several times. Control Panel says they are installed and Flash Manager in CP is OK, but when I go ONLINE to verify or check version, the page is blank. Likewise is the Online Flash Settings Manager. I have tried flushing FF cache, cookies, reset and Safe Mode - all yields zip! It all worked Ok last week. This is just starting either today or last day or so. The ONLY possible cause that I can find is that Windows published about 25 "security" and "NET Framework" updates on June 12, 13, and 14. I suspect the cause might lie there. Last time I check with forums over 500 people were looking for solution to this issue and that number is just in last 24 and it's steadily climbing. I think this is pretty pandemic for Firefox and Flash whatever the cause. If it isn't fixed it will KILL Firefox (maybe that's somebody's goal? - I can see Microsoft/Windows doing something like that to remove competition with their IE browser!).
I tried to talk to Adobe Tech about it, but got stone walled. I posted on Firefox forum, but got nothing back that was useful. Like most I am running Win 7 HP x64. I am also using Norton 360 and have set the Firewall there to FULL ALLOW for all Adobe and even tried turning it OFF for a while with no luck.
At this point, I am fully lost. I have flushed, deleted, reinstalled, updated, disabled, verified, tested, safe moded and God knows what else all without any luck. I guess I am going to start using Chrome; I really hate IE9. (Sorry, Microsoft, suck a big one ) . I am @OldeGreyWoolf on Twitter; if you find a solution, please drop me a tweet! I'll do the same! By tomorrow, I figure there will be thousands of users in this same box. Maybe then someone, some where will come up with a solution! Feel free to copy and paste this post any where/every where.

               player.waitForState(300);

Problems:
1)the file cannot be viewed with any of the players I have on my computer: Windows Media Player and Real Player fail to play it. Even JMStudio can't!!
2) when I click on the button to display the video, a null exception is thrown. sometimes, there's a message sayiong the player could not be created.
I'm completely confused with this thing. Advice would be very appreciated!
Thanks!

Hi Mustansar,
I have got the same problem. I use a clone datasource too, but I can not save anything.
Have you resolve it?
