Does AudioTransportSource block the audio thread on stop?

[simonhill-fr]

Hello,

I have an AudioTransportSource that is part of a graph with other stuff going on.
When I stop the playback, the audio output is left hanging for about 2 seconds, then after this delay the remaining data left in the audioBuffer is able to play the tail.

I found that this bit of code is causing this, and I can’t understand what use it has. Why decrement n, and why is it assigned a value of 500 ? Why block the audio thread ?

I’m tempted to derive my own class from this one and remove this code but I suppose it’s here for a reason, isn’t it ?
Or maybe I should be using something other than AudioTransportSource for playing back audio tracks in a graph ?

void AudioTransportSource::stop()
{
    if (playing)
    {
        playing = false;

        int n = 500;
        while (--n >= 0 && ! stopped)
            Thread::sleep (2);

        sendChangeMessage();
    }
}

AudioTransportSource::stop() causes a long pause

When trying to stop playing a sample in AudioTransportSource using stop(), the plugin pauses for a second and the audio artifact in the form of a click or something similar after the plugin continues working. I have seen many forum posts about this issue and none of the answers helped me. The problem disappears if you delete the lines in the AudioTransportSource::stop() method (juce_AudioTransportSource.cpp): while (--n >= 0 && ! stopped) Thread::sleep (2); Why is the thread blocki…

AudioTransportSource::stop()

Hello Jules, I’m trying to play several audio files thru AudioTransportSource. Some are in loop, some are playing, some are in stop etc… But when I stop one of them that was playing, there’s some kind of freeze happening, with all tracks being muted. I guess it could be related to the Thread::sleep (2); bellow ? [code]void AudioTransportSource::stop() { if (playing) { { const ScopedLock sl (callbackLock); playing = false; } int n = 500; while (--n >= 0 && ! stopped) …

AudioTransportSource thread confusion

Hi I might make a fool of my self now, but there is something I don’t understand with AudioTransportSource I get it to play, stop, etc, and all seems well. But when I call void AudioTransportSource::stop() it blocks the calling thread: int n = 500; while (--n >= 0 && ! stopped) Thread::sleep (2); What I want to do is to have it stop, both on user input (like a button click) or to stop at a given time (counting samples in the processing callback) Anyway it will block, if I call it from …
