I've been using the Java Sound API's to play some audio tracks (Ogg Vorbis and mp3). I've been using the VorbisSPI and MP3SPI from Javazoon.net to support these file formats. I have code sucessfully playing these formats, starting, stopping, pausing resuming. However when I first create my 'Line', it takes around 2-3 seconds for each audio track to play. The code is something like this:
I then have code in a seperate thread which reads in the bytes of audio data and writes them out to the currentLnie, something like this:
As I have said, by doing this, it takes 2-3 seconds between calling this method and my audio to start playing. I originally thought it to be a problem with my creation of the Thread. So when my object is created it now creates the Thread and starts it. This then sits in a while loop sleeping for 100ms at a time whilst not playing. Yet it still takes 203 seconds before the audio starts to play. If I do the following:
To essentially 'pause' the audio, and then sometime later I do:
Which essentially 'resumes' my audio playing again, it resumes instantly. Therefore the only thing I can put this down to is the time it's taking to create all of the objects to eventually end up with the currentLine object that I use to play that audio.
So... can anyone suggest a way that I can either rewrite this to speed it up, so it plays the audio instantly. Or is there a way I can create a Line or maybe two Line's that I can keep open and use ti play audio instantly each time (if that actually makes sense)?
Ahy help with this is greatly appreciated.
I'm not dead! I feel happy! I'd like to go for a walk! I'll even read a tiny ad:
