The GStreamer pipelines for audio demonstrate various use cases for the capture of
        audio from a file source and playback of the audio stream on a speaker.

Before you begin executing the use cases, ensure that you complete the preconditions
            mentioned in [Multimedia use cases](https://docs.qualcomm.com/doc/80-70014-50/topic/multimedia-use-cases.html).

- **[Audio (only) capture](https://docs.qualcomm.com/doc/80-70014-50/topic/audio-only-capture.html)**  

The pipelines show how to use the audio capture of single PCM audio streams that come         from an audio source and are stored in a file.
- **[Audio (only) playback](https://docs.qualcomm.com/doc/80-70014-50/topic/audio-only-playback.html)**
