Music
In the spirit of removing proprietary items to the extent that my knowledge and ability allow, I deiced to switch to the old fashion mp3 player. I chose the Sony Walkman as it had the features I liked:
- Bluetooth
- Small in size
- Expandable Memory (256GB at the moment for my use)
- Simple Interface
- Comes with music library for Windows, but could also use simple drag and drop of files to transfer music
- wide array of file types supported
Problem
I had an old laptop that contained most of the music I've horded since middle school. I simply selected all the files and placed them in my SanDisk memory. About 730 of the files were corrupted, transferring over 0 bytes.
Solution
After sorting the files by size, I then created .opus files to form my play list. I realized that I had several dozen .opus files that my mp3 could not read. I had to batch convert. All over the web I found different types of answers all that were too complex. My friend attempted to help but I got a parse error, still need to debug this. But for now- to convert a directory of *.[m4a,opus,etc] files to another type of file using ffmpeg the following command works:
for i in *.opus; do ffmpeg -i "$i" -b:a 192k "$i%.*}.mp3"; done
The above command will take all .opus files and spit out individually named .mp3 files.
Please do this in the directory where your files are
Clean up
I recommend doing a simple rm *.opus
to remove all excess opus files post convert.
