thanks.

Note that it’s not an alternative to locks – as it’s an operation upon a lock, and you still undergo the overhead of testing the lock – but it is an alternative to locking (waiting on a lock).

Glad to help!

My comments were partly because I hadn’t fully understood the ring buffer’s internals but also do to the phrasing you used…

” if the lock is contended, I pull the samples out of the ring buffer instead”

…which I took to mean that that you used the ring buffer as a fallback after testing a lock contention with another data structure (something that I’ve since discovered are called “try locks”). I was wondering about the syntax to test for a lock contention and branch, rather than wait, if it’s contended. Ross Bencina recommends it in his article as a viable alternative to locks.

Thanks again for saving me endless time. I’ve got my audio up and running with Audio Units (and TPCircularBuffer) and even have pitch scaling working (though changing pitch dynamically still needs a few kinks ironed out).

The ring buffer thing: With my implementation (TPCircularBuffer), there’s no need to lock, so no mutex overhead. I’m afraid I’m not quite sure that I follow the rest of your question though – I think you’re referring to my discussion with Rich above, about the issues with using dispatch_async and similar primitives from a realtime Core Audio thread (which incur delays). How does that relate to the writing of buffers?

Another quick question if you don’t mind: You mentioned your ring buffer solution to locking issues. How are checking that a lock is contended? How do you know the check is accurate by the time you do the next step? Have I understood correctly that this implies you are writing to 2 buffers with every disk read (and reading from the non-locked one)?

Beautiful graphics in Loopy btw…

Would it be possible to modify the plugin to run automatically and report when it finds orphans. An ideal example is the “Broken Link Checker” plugin. Also I believe the plugin fails after a while because it may be using excessive load. You could probably restrict the server load. You can see the same again in “Broken Link Checker” – Advanced – Server load limit . This way the plugin will use minimal resources and still get orphans

Thanks

Seems like you need to use your account ID, not the alias. After getting the ID it all worked fine for me.

wp-content/plugins/flickrpress/includes/interface.php:84 (flickrpress_load_items()): Couldn’t get account: User not found

but I’m pretty sure I’m entering all the details correctly, is this a pro setting or something?

Once in the callback, you check your event fire time against the host time given to you – inTimeStamp->mHostTime, which is the timestamp that corresponds to the moment in the near future that the current buffer hits the speaker (or, in a recording context, the moment that the first sound wave of the buffer hit the microphone, in the past, I think). One note: If you’re doing this from a ‘render notify’ callback, make sure you check *ioActionFlags & kAudioUnitRenderAction_PreRender is true – the callback is called once before the buffer is filled, and once after, so you probably only want it to happen at the start.
