This one could be renamed, it's in fact a backend for QMediaRecorder based on QAudioInput (which can only save to WAV). It's available on all platforms.

This is the actual audio plugin for Windows (QAudioInput, QAudioOutput, QAudioDeviceInfo). It's not really new, it just used to be embedded in the QtMultimedia library itself.

Plugins in 'plugins/audio' are backends for low-latency audio APIs. That is QAudioOutput, QAudioInput and QAudioDeviceInfo.
The ones in 'plugins/mediaservice' are backends for QCamera, QMediaPlayer, QMediaRecorder, QAudioDecoder to name only the most importants.
