Selfoptimization ffmpeg script

Question

I'd like to split mp3 Files at a specific range by silence. To do that I have the following script, but don't know how to stop and restart the search function:

 $minDuraton = 180
 $maxDuraton = 480
 $paramDB = -42
 $w_paramDB = $paramDB


 $silparam = [string]$w_paramDB+"dB:d=0.2"

C:\ffmpeg\bin\ffmpeg.exe -v warning -i "C:\mp3\test.mp3" -af silencedetect=$silparam,ametadata=mode=print:file=-:key=lavfi.silence_start -vn -sn  -f s16le  -y D:\Mailbox\09_Tools\PS_Scripte\mp3\Tmp_silents_part.txt|
%{ if ($_ -match "start"){
    $i++
    $text,$time = $_ -split "="
    $p_Duration = $time - $StartPart
    if($p_Duration -gt ($maxDuraton +10)){
    # Stop ffmepg and restart with new parameter

     ##### -please help- #####

    # editing Parameter
    $w_paramDB = [INT]($w_paramDB * 1,10)

        }
    elseif($p_Duration -ge $minDuraton ){
        $null = $PartArr.Add($time)
        $StartPart = $time
        } 
    }
}

$PartArr
$i
$segments = ($PartArr) -join ","   #PartArr | Join-String -Separator ','

$segmentsC:

C:\ffmpeg\bin\ffmpeg.exe -i "C:\mp3\test.mp3" -f segment -segment_times $segments "C:\mp3\output_silc_%03d.mp3"

THE ACTUAL SCRIPT:

function getMp3Leange($path)
    {
    $shell = New-Object -COMObject Shell.Application
    $folder = Split-Path $path
    $file = Split-Path $path -Leaf
    $shellfolder = $shell.Namespace($folder)
    $shellfile = $shellfolder.ParseName($file)
    $hoch = 2
    [int]$mp3Lange = 0
    $shellfolder.GetDetailsOf($shellfile, 27) -split ":"|ForEach-Object{$mp3Lange= $mp3Lange + ([int]$_*[math]::pow(60,$hoch));$hoch--}
    return $mp3Lange
    }




function ffmpeg_caller{
    param($datei_FullName=[STRING]"",
          $i_minDuraton  = [int] 0,

                    Write-Host "New threthold $w_paramDB!"

$o_PartArr = ffmpeg_caller -i_minDuraton 180 -datei_FullName $t_mp3  #getSilenceList

$segments = ($o_PartArr) -join ","   #PartArr | Join-String -Separator ','

$segments




C:\ffmpeg\bin\ffmpeg.exe -i $t_mp3 -f segment -segment_times $segments $o_path

The Output Error is:
