I had occasion this morning to want to copy some voice recordings I made on my Win 10 laptop to my J820. Those made on Windows are
(.M4a
)s and while 'Voice Recorder' correctly identified them as such it made no effort to play them. I did a search and came across where Rich had helped a user make a custom ringtone using online resources so, after some trial and error, I thought I'd share the method I used.
I used ffmpeg with the Windows Sub-system for Linux
(WSL
) to run the following one liners.
ffmpeg -i <infile>.m4a -ar 8000 -acodec pcm_u8 -ac 1 <outfile>.wav
Plays back fine on the J820
and:
ffmpeg -v 5 -y -i <infile>.m4a -acodec libmp3lame -ac 2 -ab 192k <outfile>.mp3
I often embed custom voice recording mp3s in Google Earth .kmz files.

In the past I have recorded the audio from my desktop to the voice recorder on my MobilePro, then I emailed it back to my desktop and converted it from there.
I think Rich's way is a lot easier.
I have not had the need to do that for a few years though.
Oh, and after all of that work the sound quality was really poor!

My method was born from necessity...I had no desktop conversion software, so I had to find on-line resources...
What a great way to make your own custom ring tones for a cell phone, eh?
