Playing a sound at regular intervals

[Daniel Glöckner]

Hi,

We're trying to play a notification sound at a regular interval (every 500ms) in a loop.

It should sound like "bing.bing.bing." and not like "bing......bing..bing...bing" if you know what I mean ;)

>From the JavaDoc we were guessing that an efficient way to do this would be to set cycle count to indefinite on the audio clip / on the media player and call play() once.

Observations:
- Cycle count doesn't work for mp3 files. No problem, just use WAV.
- The playback does not happen at regular intervals. -> not usable in this scenario

Our solution so far has been to have a scheduled executor which calls audioclip.play() every 500 ms. This creates a new thread every time (see stack trace below) and we don't like this approach.

Are there any experts for NativeMediaPlayer on this mailing list?

Kind regards,
Daniel
