vgmstream_cli:tldr:eff39

This command is used to play audio in a specific format using the vgmstream_cli and aplay tools. Here is the breakdown of each component:

• vgmstream_cli: This is a command-line tool that is part of the vgmstream project. It is responsible for decoding and playing audio files.

• ${path-to-input-adc}: This is the path to the input audio file. ${path-to-input-adc} should be replaced with the actual path on your system. This file is the one you want to play.

• -pec: This is an option for vgmstream_cli that stands for "print extra channel layout." It instructs vgmstream to output the channel layout information.

• |: This is a pipe symbol that is used to connect the output of one command to the input of another. In this case, it connects the output of vgmstream_cli to the input of aplay.

• aplay: This is a command-line tool for playing audio files on Linux. It is used here to play the audio output from vgmstream_cli.

• --format cd: This is an option for aplay that sets the audio format to CD quality (16-bit, little-endian, stereo). CD quality is commonly used for audio playback.

• --channels ${1}: This option specifies the number of audio channels to use. ${1} is a placeholder that should be replaced with the desired number of channels.

• --rate ${44100}: This option specifies the audio sample rate to use. ${44100} is a placeholder that should be replaced with the desired sample rate, which is typically 44100 Hz for CD-quality audio.

In summary, this command takes an input audio file, decodes it using vgmstream_cli, and then plays it using aplay with the specified format, number of channels, and sample rate.
