ma_sound_at_end including delay effect?

[Ar-Ess]

I want to ask if there is any way to detect "ma_sound_at_end" including the delay effect.
Right now, I have an "ma_sound sound" which has attached in its output a "ma_delay_node delay" (and that node to engine).

My system deletes that "ma_sound sound" whenever is at the end, doing:

if (ma_sound_at_end( sound ))
{
ma_sound_uninit(sound);
delete sound;
}

Is there a way to detect whether the ma_sound plus the delay has ended?
Lets say that the ma_sound lasts 1 second, but the delay elongates it until 2 seconds.
I would need to detect when those 2 seconds are over.

Thanks so much!

No, a sound has no knowledge of effects or any other node within the graph. ma_sound_at_end() is only concerned with the sound itself and will not take the state of other nodes into account.

I'm not sure off the top of my head how you'd determine if you're at the end of the tail of the delay. I guess maybe you could take the time of your delay and schedule the removal of the sound rather than immediately remove it? There's no built-in mechanism for that so you'd need to do that yourself.

Okey...
I guess I'll have to set a timer for every ma_sound.
Just to know, is there a way to retrieve the expected time of an applied delay?
I mean, I can calculate it myself with the rolloff factor and the delay time, but it is just in case there is any built in function.

Could this functionality be in your future plans of implementation, now that its mentioned?

Just to know if I will be able to refacture my code eventually

Thanks so much

No, I have no plans in supporting any functionality like that. There's no real notion of an "end" to the delay node.

Do you have one delay node per sound, and are you wanting to delete that delay node at the same time as the sound? If not, and you are keeping the delay node active, it should continue processing the tail even after the sound has been deleted.

[Ar-Ess]

Yeah, I have one delay node per sound and my code needs to delete that node plus the ma_sound. It is calculating the audio from different points multiple times per frame, so the delay must arrive in different times & rolloffs.
That's why I'm trying to delete the sound whenever the effect is finished.
