Utilizing PowerShell and FFMPEG for M4A to MP3 Conversion

Fri, 29 Dec 2023 22:00:22 +0800

I attempted to use the well-known ‘m4a-to-mp3-converter’ from maniactool to convert audio files from M4A to MP3 format, but unfortunately, it did not function as expected.

Given that many media converters utilize the ‘FFMPEG’ library, and without access to a pre-built solution for converting multiple M4A files to MP3, I opted to create my own using PowerShell.

powershell

param (
 [Parameter(Mandatory=$true)]
 [string[]]$args
)

if ($args[0] -eq "-all") {
 Write-Output $args[0]
 foreach ($file in Get-ChildItem -Filter *.m4a) {
 $filename = $file.BaseName
 ffmpeg -i $file.FullName -c:v copy -c:a libmp3lame -q:a 4 "$filename.mp3"
 }
} else {
 foreach ($var in $args) {
 $filename = (Get-Item $var).BaseName
 ffmpeg -i $var -c:v copy -c:a libmp3lame -q:a 4 "$filename.mp3"
 }
}

it just a simple parser script. Here the output:
