There's a gap when playing a music with the loop option activated #2

Open MartinMoizard opened 11 years ago

Hi,

I want to play a theme music on my iOS game using the following : [[SoundManager sharedManager] playMusic:kThemeSound looping:YES];

It is working well except that there is a gap (a small silence) when the sound is looping. I tried the sound in iTunes, there is no gap when looping.

Is there a way to fix this ?

Thanks, Martin

This may be due to the music format. I think mp3 has this problem. Try changing the format using the command line converter mentioned in the README. Unless you've already done that.

I've already done that, I tried many format and nothing changes. Are you able to play music in loop without gaps?

Hmm. I don't have a suitable sample to test with, but according to this StackOverflow, it's not possible to do gapless playback using AVAudioPlayer (which is the underlying mechanism used by SoundManager).

I don't see anything related to gapless playback on this thread...

Sorry, that's not the link I thought it was. Here's an article explaining the problem. It also contains a link to a library that supports gapless playback (I've not used it, but it sounds like it will solve your problem):
