aplay: Play a specific file (sampling rate, bit depth, etc. will be automatically determined for the file format).

aplay

$ aplay ${filename}

try on your machine

The command "aplay ${filename}" is used to play an audio file using the ALSA (Advanced Linux Sound Architecture) audio subsystem in Linux.

Here's the breakdown of the command:

"aplay" is the command-line utility provided by ALSA for playing audio files. It is used to access and control the ALSA audio devices.
"${filename}" is a placeholder for the actual name of the audio file that you want to play. The "${...}" is a syntax used in Unix-like systems (such as Linux) to substitute the value of a variable. So, in the command, you need to replace "${filename}" with the name or path of the audio file you want to play.

When you execute the command with the actual filename, it will play the audio file using the default audio device configured in your system. If you want to specify a specific audio device, you can use the "-D" option followed by the device name.

For example, if you want to play a file named "audio.wav" located in the current directory with the default audio device, you would execute the command "aplay audio.wav".

Note: This command assumes that you have ALSA installed and configured on your Linux system.
