FWIW, OpenAL Soft has an in-progress extension called AL_EXTX_buffer_sub_data, which lets you modify the buffer while it's playing. It allows you to rewrite the buffer just ahead of where it's being read from, giving lower latencies than buffer queues provides. It's not very useful when you're simply playing a pre-mixed non-interactive stream (where having a large buffer queue isn't an issue), or if you can't rewrite audio data you've already written, but it can be useful in some cases. I hope to have it done for the next version, since it's been pretty stable spec-wise. _______________________________________________ Openal mailing list [email protected] http://opensource.creative.com/mailman/listinfo/openal
