I wrote this script years ago, and now I need to mod it so I can have it resample the files in ram to save read write on my ssd does any one have any tips on how to do that?

Code: 
#!/bin/bash

working_dir="/run/media/userx/4TB_esaystore/Music"  
move_to="/run/media/userx/4TB_esaystore/Resampled_Music" 
script_dir=/home/userx/scripts
no_tags=/run/media/userx/4TB_esaystore/music_no_tags
orginals=/run/media/userx/4TB_esaystore/orginal_music

manyfiles="$(find "$working_dir" -type f -name "*.mp3" -o -name "*.Mp3" -o -name "*.MP3" -o -name "*.flac" | wc -l)"

while read FILE ; do 
    c=$FILE
    xpath=${c%/*} 
    xbase=${c##*/}
    xfext=${xbase##*.}
    xpref=${xbase%.*}
    path=${xpath}
    pref=${xpref}
    ext=${xfext}

    newFile="$pref"."mp3"

    #removes and replaces leaving the band directory and its subdirectories
    #to put the resmaped music into
    NoTags=${path/$working_dir/$no_tags}
    keep_orginals=${path/$working_dir/$orginals}
    
    bitrate="$(exiftool -p '$AudioBitrate' "$FILE")"
    #strips kpbs
    bitrate=${bitrate% *}
    echo "$bitrate"
# set check bitrate values low / high
rate2l=128
rate2h=128
    artist="$(exiftool -p '$Artist' "$FILE")"
    album="$(exiftool -p '$Album' "$FILE")"
    title="$(exiftool -p '$Title' "$FILE")"
    genre="$(exiftool -p '$Genre' "$FILE")"
