Hi @igorski
I have added processor to the input channel while recording then i dispose the engine without stop the recording after that again when switch on the inputchannel the app get crashed.

Adding the effect to the engine
_engine.getInputChannel().getProcessingChain().addProcessor(reverb);

Dispose the engine
_engine.stop(); // free memory allocated by song
_engine.dispose(); // dispose the engine

then i dispose the engine without stop the recording

Well, have you tried stopping the recording prior to disposing the engine ? 🙈

This can't be handled by the engine because when the recording stops, a notification is sent out to handle writing the file asynchronously in a separate thread. Meaning : your code needs to be aware of this. At this point, might as well adjust your code to first stop recording, prior to disposing.

To be clear: disposal is to be used when the engine should be destroyed (e.g. is not expected to do process any audio / will be recreated later).

Hi @igorski
Thank you for the reply. found the problem I am usingasyncfunction to stop and destroy recoding and engine. after handle it properly the problem get fixed.

so what's happening when i try to destroy the engine it take few min(clear other process), mean while i reinit() the engine again and add effects to process. but the first destroy method dispose both the engine. so the effects is trying to add to the destroyed engine. it cause the crash.

Thanks for your suggestion @igorski
