Conversion
This should be easy, wouldn’t you think? Of course it isn’t! Here’s a step-by-step instruction:
1. Extract the sound from the video or sound file. Write down the start and and position. For notifications don’t make it more than 3 seconds or it’ll get annoying. Do this with ffmpeg:
$ ffmpeg -i <input-file> -ss <hh:mm:ss.ms> -to <hh:mm:ss.ms> -f wav out.wav
Check with eg. ffplay if you got it right or adjust:
$ ffplay out.wav
2. Most likely you want to increase the volume:
$ ffmpeg -i out.wav -af 'volume=4|5|...> out2.wav
3. Convert to mp3
$ ffmpeg -i out2.wav -codec:a libmp3lame -qscale:a 8 out.mp3
qscale:a 8 is 70-105 kbit/s (default is 16 kbit/s, crappy)
Make a SAMSUNG S5 Galaxy acutally play it
Turned out this is the hard part.
1. Download it to the phone with “Eigene Dateien” (“My Files”?, dunno).
2. Select “Benachrichtigungston” (Notification in english?) and open with ES File explorer or something
3. Browse to the downloaded file and select it
4. OK everything
When selecting the dialog again, use “Medienspeicher”. Now the file name should show up there. Test it!
