RE: Playing a sound at regular intervals
Hi, Thanks for the explanation. For now we'll use AudioInputStream / Clip from javax.sound.sampled which seems wo work nicely for WAV clips. That API also offers continuous playback but without strange delays ;) Kind regards, Daniel > -Original Message- > From: David DeHaven [mailto:david.deha...@oracle.com] > Sent: Tuesday, August 23, 2016 4:16 PM > To: Daniel Glöckner > Cc: openjfx-dev@openjdk.java.net > Subject: Re: Playing a sound at regular intervals > > > > 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.

This creates a new thread every time (see > stack trace below) and we don't like this approach. For the moment this is a better solution, until we can get a few internal things fixed in AudioClip. In the current implementation there will always be at least one new thread created. There are bugs filed on this already, specifically: https://bugs.openjdk.java.net/browse/JDK-8090414 https://bugs.openjdk.java.net/browse/JDK-8087423 And possibly related: https://bugs.openjdk.java.net/browse/JDK-8088375 -DrD-
