]]> Comment on Corona – Audio by Justin http://www.webdevils.com/2011/11/12/corona-audio/comment-page-1/#comment-6703 Justin Wed, 07 Dec 2011 04:20:14 +0000 http://www.webdevils.com/?p=629#comment-6703 audio.loadSound is the perfect solution for short sound effects in Corona, such as a button press or an enemy exploding or points being added to your score. For longer sounds ( > 15s ) , audio.loadStream will allow your larger audio files to play without having to first load the entire file into your devices RAM. This lets your audio files to play much smoother while leaving more memory free for other processes. I did encounter a rather frustrating problem with audio.loadStream recently that I'd like to share in hopes i can save others the same frustration. The following is for more advanced users who have lots of sounds and background music in their app. While playing some voice-over clips in my app ( ~1-2min each ), I was experiencing some stuttering/skipping of the audio with occasional dropouts. I was certain that it wasn't a RAM issue and confirmed my files were being caught by the garbage collector and all references were nil'd after audio.dispose( myHandle ), but still had this strange problem that seemed to happen at random. I ultimately discovered this ended up being due to an iOS5 bug in OpenAL. The current 'Free Trial' build of Corona ( 591 ) has not resolved this issue, but if you are a subscriber, it was fixed in build 645. Be sure to subscribe and grab the latest build for the best audio support. There are also some additional 'hidden API' params you can set to have your long audio files play even smoother. Add them to your audio.loadStream to increase the buffer size like this: local myBigAudioFile = audio.loadStream( audioFile.m4a, {bufferSize=8192, maxQueueBuffers=12, startupBuffers=4, buffersQueuedPerUpdate=2}) Happy Building! audio.loadSound is the perfect solution for short sound effects in Corona, such as a button press or an enemy exploding or points being added to your score.

I am able to open the .fla from the download link at the very top (makescrollbar-class), but not the examples from SimpleScrollText_041109 with the xml feed, I always get an Unexpected File Format error when I try to open the .fla, what version of Flash are they?

I think if you try it you will come to the conclusion that it's much more flexible. Not to mention your assessment of 1 line vs five has some bad math. Your onRelease is defining a function which is equivalent to the handler function assigned to the AS3 listener. So really it's only one more line.
