QAudioOutput

QAudioOutput is a class in the Qt multimedia framework, specifically part of the QtMultimedia module. It is designed to handle audio output operations, providing a way to play audio data in various formats. The class supports different audio backends, allowing it to work across different platforms and devices. It can be used to play audio from files, streams, or raw audio data.

The QAudioOutput class provides methods to control the playback, such as starting, stopping, and pausing the audio. It also allows for the configuration of audio parameters like sample rate, channel count, and sample size. The class emits signals to notify about the state of the playback, such as when the playback starts, stops, or encounters an error.

QAudioOutput can be used in conjunction with other Qt multimedia classes, such as QAudioInput and QAudioDecoder, to create complex audio applications. It is also compatible with QMediaPlayer, which provides a higher-level interface for playing multimedia content.

The class is part of the Qt multimedia framework, which is designed to be cross-platform and easy to use. It is well-documented and comes with a variety of examples to help developers get started. However, it is important to note that the availability of certain features may depend on the underlying audio backend and the capabilities of the target platform.
