ffmpeg -i input.wav -af "adelay=3500|3500" output.wav
Add 3.5 seconds of silence to input.wav (stereo audio file). (Add to beginning)
Output to output.wav. input.wav does not change.
You can convert from WAV to MP3 by changing output.wav to output.mp3.
Changing 3500|3500 to 4200|4200 will add 4.2 seconds.
If you change 3500|3500 to 100s|100s, the additional time will be 100 seconds.
