Seconding ps. I have the same stuttering problem when triggering a very short sample (a clicking sound for a button) several times too quickly. This only seems to happen in Windows (XP), and it's on a fairly old machine, a 1.6GHz Pentium M. I've tried tinkering with the size of the buffer, but nothing seems to work. Any ideas?

I created an array of several AudioChannels with my sample and rotate between them for playback so they can overlap, and get no stutter on the machine that gave me problems.

Ok, this one took me several hours to figure out so I thought I would share. After uninstalling Vista SP2, reinstalling Java, reinstalling video drivers, and reviewing my code, I figured out my issue. Vista has the ability (not sure why) to disable it's audio driver (or something) when you unplug your headphones or the audio out. Angry

This kills Minim if you don't have a Try statement around your audio trigger, leaving your program confused and unable to progress. I don't blame Minim (I blame Vista and myself), but perhaps some catch coding can be included in the next minim release so that it just continues on without issue.

One other thing I learned... do you also use controlP5 in combo with your sound? Sometimes the button of a control may not release (this happens when the focus is pulled from the button before release), causing it to be pressed a second time when focus is returned (creating a second repeating sound). I've found in these situations, a bang can be used along with .setTriggerEvent(Bang.RELEASE);

No I don't use controlP5. In fact, I don't use any outside libraries. I should probably gradually strip out code and see if there's a point at which it works. This is pretty tiresome.

I ran into an issue with metadata track numbers. itunes sometimes includes the total track numbers for an album in a track's metadata, as in "track 1 of 10" instead of just "track 1". Because of this, AudioMetaData.track() returns something like "1/10", causing a NumberFormatException. I haven't found a way around this.

first of all, let me say thanks for the great library. i'm using it in my first project with processing and so far, so good.

except of course one problem! :)

i'm having a problem closing my files. i have 80 sound files in total and i'm playing around 20 at once, selected via an external interface. but when i trigger the stop() function, also via the external interface, i get the following error:

Exception in thread "Animation Thread" java.lang.NullPointerException at ddf.mimin.javasound.JSBaseAudioRecordingStream.close(JSBaseAudioRecordingStream.
java:362) ... etc

i have all my AudioPlayer objects listed in the stop() function (player1.close(), player2.close, player3.close(), and so on...) and i call the stop() function from within a conditional statement in draw(). so effectively i try to close all my AudioPlayer objects in the stop function regardless of whether or not they're being used.

i don't think the problem is that i'm trying to close objects that are not playing, as i did a bit of debugging that indicated this isn't the problem. does anyone have any suggestions or can point me to some resources that could help me? i hope i've explained myself clearly...
