/* Register a special effect function. At mixing time, the channel data is

* After it passes through all the functions, it is mixed into the final

* output stream. The copy to buffer is performed once, then each effect

* function performs on the output of the previous effect. Understand that

* this extra copy to a buffer is not performed if there are no effects

* registered for a given chunk, which saves CPU cycles, and any given

* effect will be extra cycles, too, so it is crucial that your code run

* fast. Also note that the data that your function is given is in the

* format of the sound device, and not the format you gave to Mix_OpenAudio(),

* although they may in reality be the same. This is an unfortunate but

* necessary speed concern. Use Mix_QuerySpec() to determine if you can

* handle the data before you register your effect, and take appropriate

* actions.

* You may also specify a callback (Mix_EffectDone_t) that is called when

* the channel finishes playing. This gives you a more fine-grained control

* than Mix_ChannelFinished(), in case you need to free effect-specific

* resources, etc. If you don't need this, you can specify NULL.

* You may set the callbacks before or after calling Mix_PlayChannel().

* Things like Mix_SetPanning() are just internal special effect functions,

* so if you are using that, you've already incurred the overhead of a copy

* to a separate buffer, and that these effects will be in the queue with

* any functions you've registered. The list of registered effects for a

* channel is reset when a chunk finishes playing, so you need to explicitly

* set them with each call to Mix_PlayChannel*().

* You may also register a special effect function that is to be run after

* final mixing occurs. The rules for these callbacks are identical to those

* in Mix_RegisterEffect, but they are run after all the channels and the

* music have been mixed into a single stream, whereas channel-specific

* effects run on a given channel before any other mixing occurs. These

* global effect callbacks are call "posteffects". Posteffects only have

* their Mix_EffectDone_t function called when they are unregistered (since

* the main output stream is never "done" in the same sense as a channel).

* You must unregister them manually when you've had enough. Your callback

* will be told that the channel being mixed is (MIX_CHANNEL_POST) if the

* processing is considered a posteffect.

*

* After all these effects have finished processing, the callback registered

* through Mix_SetPostMix() runs, and then the stream goes to the audio

* device.

* so when they are mixed through this effect, the positioning will sound

* correct. You can convert them to mono through SDL before giving them to
