Hi Gary, Qt 6.8 introduces a new QAudioBufferOutput API for this purpose. I hope this will help you. If you encounter any issues when testing the API, please feel free to report them to our JIRA bug tracker.

For example, it can be use to attach to a QMediaPlayer to create real-time audio visualization. In Qt 6, QAudioProbe no longer exists, and it seems there are also no alternatives that provides the ability to inspect/probe an existing QAudioOutput (QAuidoOutputProxy?). By reading the Qt 6 Multimedia documentation, I know one option is use QAudioDecoder and QAudioSink instead of QMediaPlayer, but there are some downside too. If we go with QAudioSink, we should handle all underlying details manually, beside that, it seems we also won't be able to make use of QMediaMetaData to fetch media metadata. So, what's the suggested method to create real-time audio visualization for QMediaPlayer? Or is there any plan to re-introduce QAudioProbe or similar classes that provides the same ability? Thanks!
