flac:tldr:80fca

The given command:

flac -d -o ${path-to-output-wav} ${filename-flac}

is used to decode a FLAC audio file into a WAV format.

Let's break down the components:

• flac: This is the command-line utility for FLAC, a lossless audio codec. It is used to perform various operations on FLAC files.
• -d: This flag instructs the flac utility to decode the input FLAC file.
• -o: This flag specifies the output file format.
• ${path-to-output-wav}: This is a placeholder for the desired output file path and name, where the resulting WAV file will be saved. You need to replace ${path-to-output-wav} with the actual path and file name, including the .wav extension. For example, you could use output.wav if you want to save the converted file as output.wav in the current directory, or you may specify the complete path like /path/to/output/output.wav.
• ${filename-flac}: This is another placeholder for the input FLAC file path and name that you want to decode. Similarly, you need to replace ${filename-flac} with the actual path and file name of the FLAC file to be converted, including the .flac extension. For example, you could use input.flac if the file you want to decode is named input.flac in the current directory, or you may specify the complete path like /path/to/input/input.flac.

Once you substitute the placeholders with the actual paths and file names, you can execute the command to decode the specified FLAC file into a WAV file at the specified output path and name.
