Well, 😃 IMHO this is a documentation bug! If one person falls into a trap, it might be their fault, but if two do… The documentation should say something like: [list] [_]prepareToPlay() is guaranteed to be called at least once before the first call to getNextAudioBlock(), or before the first call to getNextAudioBlock() after releaseResouces() has been called. [/_] [_]releaseResources() is guaranteed to be called at least once after the last call to getNextAudioBlock() or prepareToPlay(). [/_] [_]There are no other guarantees. Some streams will call prepareToPlay()/releaseResources() repeatedly if they stop and start, others will not. It is possible for releaseResources() to be called when prepareToPlay() has not.[/_][/list] Or another way to look at it that I find a little more intuitive: [list][_]An AudioStream can only have two states, prepared and released, [/_] [_]An AudioStream must always start and end its life in the released state… [/_] [_]…but getNextAudioBlock() can only be called if the AudioStream is in the prepared state. [/_] [_]prepareToPlay() puts the AudioStream into the prepared state; releaseResources() puts it in the released state. [/_] [_] prepareToPlay() and releaseResources() can be called at any time, in any order.[/_][/list] --- _[View the full topic](https://forum.juce.com/t/preparetoplay-and-releaseresources-are-not-getting-called/5562)._
