Some converted audio and video files get sporadic cracking noises during playback on an iPod Nano 3rd generation.
It can happen dozens of times during 30 minutes. Some times 3 times per second, some times 20 seconds apart. There is no clear pattern.
Enclosed is a small excerpt that includes:
- An original input file
- The output file from FFmpeg
- What the output file sounds like when played on the iPod (played through a speaker and recorded with a microphone)
The command line was a simple
ffmpeg -i original.ac3 converted.m4a. Version is latest Git head, run on macOS.
What could cause these crackling noises? Is this a known issue? How can I prevent them from occurring?
