I need silent Opus audio files range of 1 second to 60 minutes.
I found this example for wav files:
60 seconds of silent audio in WAV:
ffmpeg -ar 48000 -t 60 -f s16le -acodec pcm_s16le -ac 2 -i /dev/zero -acodec copy output.wav
60 seconds of silent audio in MP3:
ffmpeg -ar 48000 -t 60 -f s16le -acodec pcm_s16le -ac 2 -i /dev/zero -acodec libmp3lame -aq 4 output.mp3
How can I do it for opus with using ffmpeg or similar tool?
