## Prerequisites - Enable SSH in Permissive mode to securely access your host device. For instructions, see [How to SSH?](https://docs.qualcomm.com/bundle/publicresource/topics/80-70014-254/how_to.html#how-to-ssh-) - Use the following command to enter the SSH shell and execute the use cases: ssh root@Copy to clipboard - Run the following command to enable the Permissive mode: setenforce 0Copy to clipboard - Run the following command to enable the display: export XDG_RUNTIME_DIR=/dev/socket/weston && export WAYLAND_DISPLAY=wayland-1Copy to clipboard - Run the following command to push the files from host machine: scp root@:/opt/Copy to clipboard ## Use case A common use for this application can be to encode live audio data for streaming or storage. For this use case, you may have a live audio source (like a microphone or an internet radio stream) and you want to encode this audio data into a more compact or standardized format for efficient transmission or storage. Do the following to execute the use case: 1. Use the following syntax command to run the application for different audio formats: `gst-audio-encode-example -o --audio_format=` The table provides a description of the command-line parameters: | Command-line parameter | Description | | --- | --- | | `-o` | Specifies the absolute path to the output audio
file. | | `-format` | Specifies the format of the audio file:

  • 1 = FLAC


  • 2 = WAV


| You can use the following commands to run the application for FLAC and WAV audio formats: - Encode FLAC audio: gst-audio-encode-example -o /opt/.flac --audio_format=1Copy to clipboard - Encode WAV audio: gst-audio-encode-example -o /opt/.wav --audio_format=2Copy to clipboard To stop the use case, press CTRL + C. ## Expected output The captured audio is encoded and written to a file based on the chosen format (FLAC or WAV). Use the following command to pull the files from host machine: scp root@:/opt/ Copy to clipboard ## Pipeline flow In the audio encoding, the pipeline differs slightly based on the encoding format. The table lists the plugins used to execute the audio recording pipeline: | Plugin | FLAC | WAV | | --- | --- | --- | | pulsesrc | Captures audio from the system
sound device. | Captures audio from the system
sound device. | | capsfilter | Ensures the audio is in a format suitable for the FLAC
encoder. | – | | audioconvert | Converts the audio to the required
format. | Converts the audio to the required
format. | |

  • flacenc


  • wavenc


| flacenc encodes the audio into FLAC format. | wavenc encodes the audio into WAV format. | | filesink | Writes the encoded audio to a
file. | Writes the encoded audio to a
file. | **Parent Topic:** [Sample applications for video and audio](https://docs.qualcomm.com/doc/80-70014-50/topic/audio-sample-applications.html) Last Published: Oct 27, 2025 [Previous Topic Audio playback](https://docs.qualcomm.com/bundle/publicresource/80-70014-50/topics/gst-audio-decode-sample.md) [Next Topic Video transforming](https://docs.qualcomm.com/bundle/publicresource/80-70014-50/topics/gst-transform-example.md)
