2.a. Command (Targeting 1 folder):

# Edit the path below to your specific folder

$TargetFolder = "C:\Users\example\Music\x_x"

$Files = Get-ChildItem -LiteralPath $TargetFolder -Include *.flac, *.mp3 -File
foreach ($File in $Files) {
    Write-Host "Standardizing: $($File.Name)" -ForegroundColor Cyan
    $HasVideo = & ffprobe -v error -select_streams v:0 -show_entries stream=codec_name -of csv=p=0 "$($File.FullName)"
    $TempFile = $File.FullName + ".tmp.flac"
    if (![string]::IsNullOrWhiteSpace($HasVideo)) {
        & ffmpeg -i "$($File.FullName)" -map 0:a -map 0:v:0 -c:a copy -c:v mjpeg -pix_fmt yuvj420p -vf "scale='min(1000,iw)':-1" -disposition:v:0 attached_pic "$TempFile" -y -loglevel error
    } else {
        & ffmpeg -i "$($File.FullName)" -c:a copy "$TempFile" -y -loglevel error
    }
    if ($LASTEXITCODE -eq 0) {
        Remove-Item -LiteralPath $File.FullName -Force
        Rename-Item -Path $TempFile -NewName $File.Name
    }
}

2.b. Library-Wide Standardizer (Automated) Targeting whole library and subfolders within a path.

If you want to process everything inside your main Music folder at once without specifying sub-folders.

• Scans recursively through all subfolders.
• Skips audio re-encoding entirely.
• Ensures no gray pixel formats crash the player.

Command (Whole Library):

$ParentFolder = "C:\Users\example\Music"

$Files = Get-ChildItem -Path $ParentFolder -Recurse -Include *.flac, *.mp3 -File
foreach ($File in $Files) {
    $HasVideo = & ffprobe -v error -select_streams v:0 -show_entries stream=codec_name -of csv=p=0 "$($File.FullName)"
    $TempFile = $File.FullName + ".tmp.flac"
    if (![string]::IsNullOrWhiteSpace($HasVideo)) {
        & ffmpeg -i "$($File.FullName)" -map 0:a -map 0:v:0 -c:a copy -c:v mjpeg -pix_fmt yuvj420p -vf "scale='min(1000,iw)':-1" -disposition:v:0 attached_pic "$TempFile" -y -loglevel error
        if ($LASTEXITCODE -eq 0) {
            Remove-Item -LiteralPath $File.FullName -Force
            Rename-Item -Path $TempFile -NewName $File.Name
            Write-Host "Success: $($File.Name)" -ForegroundColor Green
        }
    }
}

individual file error during re-encoding:

Use this only when a file (like an .m4a with a broken image) refuses to play or convert

$f = "C:\Users\example\Music\x_x\Juice WRLD - moonlight.m4a"; ffmpeg -i $f -vn -c:a flac -compression_level 5 ([System.IO.Path]::ChangeExtension($f, ".flac")) -y

Bonus: Timed Lyrics (.lrc) Downloader

$ParentFolder = "C:\Users\example\Music"

$Files = Get-ChildItem -Path $ParentFolder -Recurse -Include *.flac, *.mp3, *.m4a -File
foreach ($File in $Files) {
    $LrcPath = Join-Path $File.DirectoryName ($File.BaseName + ".lrc")
    if (Test-Path -LiteralPath $LrcPath) { continue }
    $SearchTerm = [uri]::EscapeDataString(($File.BaseName -replace "\(.*?\)", "").Trim())
    try {
        $Match = (Invoke-RestMethod "https://lrclib.net/api/search?q=$SearchTerm") | Where-Object { ![string]::IsNullOrEmpty($_.syncedLyrics) } | Select-Object -First 1
        if ($Match) { 
            $Match.syncedLyrics | Out-File -LiteralPath $LrcPath -Encoding utf8
            Write-Host "LRC Found: $($File.BaseName)" -ForegroundColor Green 
        }
    } catch {}
    Start-Sleep -Milliseconds 200
}

Bonus: Genre Normalization

Mapping Table:
Converts same gerne across different languegues into 1 cohisive one for example:

Alternatif et indé	alternativ und indie
alternative & indie	alternative en indie
alternativo & indie	= into 1

Paste the tags that are in different langueges or duplicate and ask AI to insert those changes in your command. The command bello wis just a example:

$GenreMap = @{"ロック"="Rock"; "ワールド"="World"; "Alternatif et indé"="Alternative"}
$Files = Get-ChildItem -Path "C:\Users\example\Music" -Recurse -Include *.flac, *.mp3
foreach ($File in $Files) {
    $Current = & ffprobe -v error -show_entries format_tags=genre -of default=noprint_wrappers=1:nokey=1 "$($File.FullName)"
    if ($GenreMap.ContainsKey($Current.Trim())) {
        $New = $GenreMap[$Current.Trim()]
        $Temp = $File.FullName + ".tag.tmp"
        & ffmpeg -i "$($File.FullName)" -c copy -metadata genre="$New" "$Temp" -y -loglevel error
        Move-Item -LiteralPath $Temp -Destination $File.FullName -Force
    }
}

Lastly. Transfer (Robocopy)

The fastest way to move your library to your external storage.

robocopy "C:\Users\example\path\from" "F:\Music\example\path\to" /E /MT:32 /Z /R:3 /W:5 /FFT

I am currently ironing out 1 last thing which is the cable connection selector. It is currently misrepresenting the selection. [ Specified at 25:18 ]

Other than that i made a tutorial on how to theme the echo mini ( it's maybe a bit unclear for some so feel free to ask questions )

Once the issue at 25:18 is sorted then i can link the files including my photoshop work files since some also asked for those. ( Hoping to be with the issue and files before the video goes live ) Its 5am here btw. Am running on coffee!

Hope you all enjoy it as much as I did making it. Will look into updating it to 3.5.0 maybe

Hi themers!

I am in the process of making a cyber deck, ASCII art / retro futuristic theme. With mono spaced font wherever possible.

I am struggling to understand a few things.

There are 2 tools so far that allow you to patch the firmware.

I don't know which one is the safest of the two and by safe i mean fool proof. (Making sure that it matches the original firmware weather by name or by size) flame-ocean.not.ci vs Echo-Mini-Customizer.exe

Lastly i wonder about file size. The battery icon i just got done theming. The original was the 497bytes and mine turned out to be a 4.22kb which is basically 4220bytes. That is screaming bricked 🧱 to me.

Lastly can i mix and match or is there like a comprehensive tutorial to which a noobie like me follow in order to avoid future headaches? So far ive only come across how to download and flash custom bootanim.

Any feedback or tips would be appreciated i will be sure to post some updates on how it's coming along. I am very happy with the bootanim a 3d ascii animation of the echo mini with some iems wrapped around it.

Ps: i usef Echo-Mini-Customizer.exe to wxctract the assets and i am using them as blueprints and yet my file sizes are still massive. Am still on 24bit and all the other canvas settings are identical as the default.
