Audio_RegHardwareHook())

int Audio_RegHardwareHook(bool isAdd, audio_hook_register_t* reg)

Allows you to get callback from the audio thread before and after REAPER's processing.

Can be used to get Reaper to call back before and/or after it outputs audio to the audio hardware. Useful for doing stuff synched to the audio engine at the ASIO/etc block size granularity.

Probably not usable from ReaScript, very likely unsafe and/or too slow - in that interpreted languages are generally (always?) an order of magnitude slower than compiled languages.

From C++ extensions code the function works more or less as expected, but you do need to avoid calling anything too time consuming there.
