     10== Async Mixer == 
     11 
     12This is based on the adder element, except I replaced the collector with a task running on the sink pad. Each sink pad has it's own g_queue where it stores buffers. _loop will scan all the pad queues and mix the available buffers for transmission, regardless of time stamps. Basically, if the data is there it is meant to be played, ASAP.

     14The caps negotiation is a bit hacked up. The first sink or source pad to have _setcaps called has its caps forced on all others, without option for renegotiation. I wanted to make it so that the src pad had to negotiate first, but this didn't seem to be an option. So if you just fixate/filter link the the sink pads within an application you'll get the right caps on the output.

     16== GSM == 
     17 
     18These are hacked up GSM depayloaders and decoders, which simply pass the clock-rate/rate caps parameters down the chain, so we can do GMS-8k, GSM-16k, etc.
