Added AEAudioFileStreamer class, which serves the same purpose as AEA… #163

…udioFilePlayer, but it streams the audio data from disk instead of preloading it all into active memory.

Duration can be incorrect because _lengthInFrames will be zero until the channel is added to a controller.

Seems that the easiest fix is to move the _lengthInFrames calculation out of setupURL:error: and into the initializer.
I've never run into this issue because I always add a channel immediately after creating it. Then set channelIsPlaying (or call the play function on this class) when ready to play. Is there any reason not to add a channel immediately? Should there be a TAAE best practice regarding this?

While I don't believe that setting of region.mStartFrame is done incorrectly, it appears that region.mFramesToPlay is set incorrectly when the audio controller's sample rate doesn't match the file's. Perhaps _lengthInFrames is calculated incorrectly in this case. |
