convert music to image and back
<p>i am trying to convert a music file (actually mp3) to a image and then back from image to mp3. It may sound crazy but im editing afterwards parts of the image and then convert it back to mp3.</p>

<p>My actual solution is this way:
MP3 --> convert to wav --> convert to base64 --> convert to pixel's per byte / time (10s) .
then the opposite way to go back.</p>

<p>Because this is depending on the length very resource intensive i am looking for a way to get a graphical output much quicker and render it back much quicker... i dont care about which programming language... im more looking for a better (quicker way) to do it that gets the same result. Most MP3's are songs and between 3-6 Minutes long. So the images are getting very big ;=)</p>

<p>How would you approach this? currently my shell script needs 19 seconds for 1 song which is a way to long. Converting it back takes only 12-14 seconds... </p>

<p>Looking for a solution in Linux with ffmpeg and shell scripts.</p>
