pw-record:tldr:15aec
This command is not a standard command, so its exact functionality may vary depending on the specific system or software it is used in. However, we can break down its general structure and infer its purpose.
The command seems to be using a utility or script called "pw-record". It likely performs some kind of audio recording functionality.
The options provided are as follows:
--rate=${6000}: This option sets the recording rate or sample rate to 6000. The recording rate refers to how many samples of audio are captured per second. A higher rate generally results in better audio quality but larger file sizes.
${filename-wav}: This part likely represents a placeholder for the name of the output file. The actual filename would be substituted in place of ${filename-wav}. The ".wav" extension suggests that the output file would be in the WAV audio format.
Overall, it seems that this command is possibly used to perform an audio recording at a rate of 6000 samples per second and save the recorded audio to a file with a specified filename in WAV format.
