  • iPhone SDK Smaller CAF files: lower recording quality with Audio Queues?

    - by Nick
    In my iPhone app I have voice recording functionality the utilizes Audio Queue voice recording functions of the SDK. I'm saving directly to CAF format and using the following settings for the AudioStreamBasicDescription reference: audioFormat.mFormatID = kAudioFormatLinearPCM; I can see that there are other format ids I could use like: kAudioFormatLinearPCM kAudioFormatAppleLossless kAudioFormatAppleIMA4 kAudioFormatiLBC kAudioFormatULaw kAudioFormatALaw My knowledge of sound formats is very limited so my question is... which of these should I use to create the lowest compressed audio recording files? Plus, are there other settings I should apply to lower the quality and filesize even further?

  • Flash/Flex: play embedded AAC audio?

    - by aaaidan
    I'm pretty sure of the answer, but just wanted to check with you all. Is it possible to play an embedded AAC file in Flash/Flex somehow? I know you can playback embedded MP3 files, but I hear that you can't do that with AAC. Anyone know any sneaky ways to get around this? By way of illustration, here's come code. [Embed(source='../../audio/music02.m4a', mimeType="audio/aac")] private static const __ExampleMp4File:Class; public var myMp4Sound:Sound = new __ExampleMp4File(); public function EmbeddedAudioTest() { myMp4Sound.play(); }

  • get rotation direction of UIView on touchesMoved

    - by mlecho
    this may sound funny, but i spent hours trying to recreate a knob with a realistic rotation using UIView and some trig. I achieved the goal, but now i can not figure out how to know if the knob is rotating left or right. The most pertinent part of the math is here: - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint pt = [touch locationInView:self]; float dx = pt.x - iv.center.x; float dy = pt.y - iv.center.y; float ang = atan2(dy,dx); //do the rotation if (deltaAngle == 0.0) { deltaAngle = ang; initialTransform = iv.transform; }else { float angleDif = deltaAngle - ang; CGAffineTransform newTrans = CGAffineTransformRotate(initialTransform, -angleDif); iv.transform = newTrans; currentValue = [self goodDegrees:radiansToDegrees(angleDif)]; } } ideally, i could leverage a numeric value to tell me if the rotation is positive or negative.

  • Supporting multiple screen sizes with Android using ImageButtons

    - by droidy
    I've read the Android documentation: http://developer.android.com/guide/practices/screens_support.html but still have some questions. I'm trying to design a music application which basically has images of the instrument (ImageButton) that play a sound when clicked. However, I'm confused about how to have the ImageButtons scale to fit all the different screen sizes and how to position them. Which layout is best used for needing to position ImageButtons in specific locations on the screen? (i.e. cymbals on a drum set) FrameLayout, RelativeLayout? If I only really care about medium and large screens, do I need to create different resources (images) for both as well as a different XML layout to position them? I'm trying to find the simplest way to do this without having to create a separate layout XML file for positioning/size and separate image resources for each screen. Any guidance is greatly appreciated. Thanks!

  • HTML5 Video Volume

    - by Mikushi
    Hi, i'm currently working on a HTML5 video player, i got it working fully everywhere, except on the freakin iPad. Basically, i can control everything, except the sound, i have a mute button, it works fine on Google Chrome, FF3.6 and Safari on Mac OS, but on the iPad no matter what value i put in video.volume, there is no change happening. Anybody got it working properly? Code: <video src="video_url" width="608" height="476" autobuffer="autobuffer" id="html5-player" preload> Your browser doesn't support HTML5. </video var muted = false; $j('.player-mute').click(function(){ if(muted) { videoPlayer.volume = 1; muted = false; } else { videoPlayer.volume = 0; muted = true; } });

  • Distributing APNS providers

    - by Sam
    I'm writing a business-focused iPhone app which includes a self-hosted server component. I'd like to include push notification functionality in the server; reading through the programming guide it looks as if this would involve either: Distributing the provider certificate with the server component - this doesn't sound like a terribly good idea (even if Apple permits it?) Hosting a shared notification provider and forwarding notifications to APNS from the servers. For an ongoing, high-availability service, this is likely to require including a subscription pricing component, which I would prefer to avoid. Require customers to apply for their own provider certificate. However, it's not clear whether multiple organisations are allowed to apply for provider certificates with a single bundle ID, and it would significantly increase the barrier to adoption. APNS looks to me as if it's specifically geared for centrally hosted services. Is anyone distributing self-hosted notification providers? Are there any other options?

  • Looking for programs on audio tape/cassette containing programs for Sinclair Z80 PC?

    - by DVK
    OK, so back before ice age, I recall having a Sinclair ZX80 PC (with TV as a display, and a cassette tape player as storage device). Obviously, the programs on cassette tapes made a very distinct sound (er... noise) when playing the tape... I was wondering if someone still had those tapes? The reason (and the reason this Q is programming related) is that IIRC different languages made somewhat different pitched noises, but I would like to run the tape and listen myself to confirm if that was really the case...

  • [Programming General] Advantages of using software framework

    - by ignatius
    Hello, I was reading these days about large projects implementation in python and Flex, and very often people praise the use of framework (like Cairngorm, PureMVC or others) over traditional OOP coding. I think i dont really understand the advantage of using FW, which is the strong point over classic programming? how big should be the project in order to use FW? it is intended mainly for web-applications? or can be used for desktop apps as well? hope, all these doubts dont sound stupid to you, i am not Computer engineer, just electronic, so my knowledge of sw architecture is very limited.

  • NSWindow does not respond to keystroke command-s

    - by wackazong
    Hello, it may pre very simple, but cannot find it: I have three windows in three separate NIBs in my application. One is opened when a new document is opened, the other two can be opened from the program's window menu. The problem is: two windows (in them the one that is opened at the beginning) accepts the normal keystroke as for example command-s for save, and the other one does not and gives a warning sound instead. I cannot figure out the difference between the two windows or their controllers. I know it will have to do with the responder chain, but I am left clueless. Any ideas? Thanks, wackazong

  • Testing sample code in python modules

    - by Andrew Walker
    I'm in the process of writing a python module that includes some samples. These samples aren't unit-tests, and they are too long and complex to be doctests. I'm interested in best practices for automatically checking that these samples run. My current project layout is pretty standard, except that there is an extra top level makefile that has build, install, unittest, coverage and profile targets, that delegate responsibility to setup.py and nose as required. projectname/ Makefile README setup.py samples/ foo-sample foobar-sample projectname/ __init__.py foo.py bar.py tests/ test-foo.py test-bar.py I've considered adding a sampletest module, or adding nose.tools.istest decorators to the entry-point functions of the samples, but for a small number of samples, these solutions sound a bit ugly. This question is similar to http://stackoverflow.com/questions/301365/automatically-unit-test-example-code, but I assume python best practices will differ from C#

  • AVAudioPlayer not looping

    - by Nick
    Hey guys, I have this code: - (id<SelfReleasingSound>) initWithFilepath: (NSString *) filepath { self = [super init]; if(self != nil){ NSData * soundFileData = [NSData dataWithContentsOfFile: filepath]; NSError * error; player = [[AVAudioPlayer alloc] initWithData: soundFileData error: &error]; if(error != nil){ JNLogAlert(@"Failed to load sound(%@)", filepath); } volume = 1.0; loops = 0; player.volume = volume; player.numberOfLoops = loops; [player prepareToPlay]; } return self; } - (void) play { player.numberOfLoops = loops; JNLogString(@"PLAYING: %D LOOPS", player.numberOfLoops); [player play]; } JNLogString is a wrapper for NSLog, and while my program says this: 2010-03-24 03:39:40.882 Bubbleeh[50766:207] JNSoundFile.m:40 PLAYING: 5 LOOPS It actually only plays 1 time, as if numberOfLoops were 0. Am I doing something wrong? Thanks in advance,

  • shouldAutorotateToInterfaceOrientation isn't getting called

    - by morgancodes
    What sort of conditions might prevent my UIViewController's shouldAutorotateToInterfaceOrientation method from being called? I've resorted to using NSNotificationCenter to listen for UIDeviceOrientationDidChangeNotification events, but would love to get the autoRotation behavior working properly. A couple shots in the dark about what's going wrong: Maybe I'm not creating my view controller correctly? Maybe it needs to be inserted in the responder chain and somthething I'm doing is preventing that from happening normally? This seems unlikely to me since my view controller is recieving touch events. Maybe the fact that the view contained by my controller relies on OpenGL has something to do with shouldAutorotateToInterfaceOrientation not getting called? Do either of these sound remotely possible as being responsible? Any other ideas of things to look at?

  • Static compilation in the .NET world

    - by AngryHacker
    I'll be writing a small desktop app for a client that has WinXP machines and they won't be installing the .NET framework (at least not for me). So my choices are limited to either C++ or VB6, neither of which sound great. I remember reading back in the day that Mono came up with a static compiler, but recently the only thing I could find is Miguel de Icaza's entry on static compilation for a game engine for the purposes of running the app on the iPhone - not what I had in mind. Are there any products out there, free or commercial that will allow me to statically compile my .net 3.5 winform app? Thanks

  • ffmpeg 0.5 flv to wav conversion creates wav files that other programs won't open.

    - by superrebel
    Hi, I am using the following command to convert FLV files to audio files to feed into julian, a speech to text program. cat ./jon2.flv | ffmpeg -i - -vn -acodec pcm_s16le -ar 16000 -ac 1 -f wav - | cat - > jon2.wav The cat's are there for debugging purposes as the final use will be a running program that will pipe FLV into ffmpeg's stdin and the stdout going to julian. The resulting wave files are identified by "file" as: jon3.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 16000 Hz VLC (based on ffmpeg) plays the file, but no other tools will open/see the data. They show empty wav files or won't open/play. For example Sound Booth from CS4. Has anyone else had similar problems? Julian requires wav files 16bit mono at 16000 Hz. Julian does seem to read the file, but doesn't seem to go through the entire file (may be unrelated). Thanks, -rr

  • Getting started with Windows Azure

    - by jonhobbs
    Hi All, I'm going to sound like a complete newbie here but here goes... I've just signed up for a Windows Azure account and was hoping to get a simple hello world aspx page up and running in a browser to see how it all works but I can't seem to find a simple guide to getting a very simple web application running. I've got as far as setting up a "service" and going onto the "deploy" page but it's asking me upload an "application package". I've looked on MSDN but there aren't any simple guides, just reams of documentation talking about "roles" and "development fabric". For somebody that is proficient in HTML/CSS and knows a little abit about asp.net it may just as well be in another language. So, does anybody know how to upload a simple aspx page and then access it in a browser? Jon

  • How do you test your blackberry application on the device?

    - by Kai
    This may sound very noobish, but I can't seem to get my app to my blackberry. I was trying to follow the beginning blackberry development book's guide, but maybe I just missed the point somewhere. For remote download, Is it really as simple as drop the COD and JAD files in the same folder on your server then just navigate to the URL with your device's browser? The book says it should prompt a download screen, but all I get is a page full of cryptic characters. My app is a simple slideshow. Uses no signed things and is not MDS enabled. Did I forget something? Any help would be appreciated. Thanks

  • making urllib request in Python from the client side

    - by mridang
    Hi Guys, I've written a Python application that makes web requests using the urllib2 library after which it scrapes the data. I could deploy this as a web application which means all urllib2 requests go through my web-server. This leads to the danger of the server's IP being banned due to the high number of web requests for many users. The other option is to create an desktop application which I don't want to do. Is there any way I could deploy my application so that I can get my web-requests through the client side. One way was to use Jython to create an applet but I've read that Java applets can only make web-requests to the server it is deployed on and the only way to to circumvent this is to create a server side proxy which leads us back to the problem of the server's ip getting banned. This might sounds sound like and impossible situation and I'll probably end up creating a desktop application but I thought I'd ask if anyone knew of an alternate solution. Thanks.

  • Taking video from video camera and displaying it with MPMoviePlayerController IPhone SDK

    - by Daniel
    Has anyone tried taking a video from the camera and then using the video player provided to play it? When you take the video in portrait mode, sometimes the movie will play (when the player puts it in landscape mode) and when it puts it in portrait mode you cannot view the movie all you hear is sound,sometimes in landscape mode is flickers and does not play right, has anyone encountered this and found a way to fix it? My code to play the video looks like this: - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSURL *urls=[info objectForKey:@"UIImagePickerControllerMediaURL"] ; moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[info urls]]; if (moviePlayer) { [moviePlayer play]; } } I checked settings on the docs nothing seems like it would fix this...Thanks

  • options for producing audio with GWT

    - by Kaffeine Coma
    What options are there for producing audio in a GWT app? I'm thinking of making a simple game, but I'm disappointed to see that there's still not much progress on audio support directly in GWT (yes, I realize that's largely due to lack of underlying browser support; looking forward to HTML5!) This blog post says that "audio support in GWT is rapidly evolving", yet I don't see updates in over a year, at least not at that site. It seems these are the available options: GWT Voices GWT SoundManager GWT Sound GWT Incubator I believe most of these (all of them?) rely on Flash to produce audio. I'm most inclined to go with the GWT Incubator, as that's where features slated for inclusion in GWT get started, but I've no real recommendations to go on. I would appreciate hearing about your experiences with any of these libraries, thanks.

  • What Features Do You Want To See in .NET 5/C# 5?

    - by Randolpho
    .NET 4 and Visual Studio 2010 are finally here, along with a host of new features. But we wouldn't be who we are if we didn't long for a feature that didn't make the cut, or that was never even considered. So sound off and let the folks at Microsoft know: What features do you want to see in .NET 5? What features do you want to see in C# 5? F#? VB.NET? Before you vote to close: some may find this question too subjective to let stand, but there are other threads that have stood the test of time. Let this one stand as well.

  • iPhone GPS Development - Tips + Tricks

    - by Keith Fitzgerald
    Hello - I'm looking for some feedback, blog links, etc that offer some tips and tricks for iPhone GPS development. I've read and understand the API, I have my demo app up and running, etc but I have run into some "quirks" with gps on iphone. For example, it seems that you you will receive a lot less location updates when your iphone enters "power save" mode. I've read that you can combat this by playing music in your application [not sure if this is true]. It also seems that, terms of making a reasonable pedometer, you should filter out any reading with horizontal accuracies less than 20 meters. Does this sound right? Is there any kind of checklist out on the web for iphone gps gotchas? Thanks in advance.

  • Concurrency Violation in NHibernate( c#) example

    - by vijaysylvester
    For quite some time , I was reading about the optimistic concurrency in NHibernate. If what i understood was correct then the below sample should hold good. Consider two transactions T1 and T2. When T1 and T2 are done simultaneously , the state(DB entries) gets updated with the values of the most latest update.(T1 or T2). Though it seems to be conceptually sound , how do i simulate this for the purpose of understanding and integration testing.? Can someone help me with a sample c# code.? Thanks , vijay

  • Mac OS : creating a background periodic simple script

    - by Julien
    Hi folks ! I have a friend who wants something quite easy : he has a mac, and he would like a very simple script/app that runs in the background. The goal is to replace a file every 5 minutes with one downloaded from the internet. I would also like a menu on the top bar (like the clock on Mac Os, the wifi, the sound, Dropbox,...) What would be the easiest way to do that ? Objective C ? AppleScript ? Do you guys have any inspiration for that ? Thanks a lot Julien
