Hi,

I noticed that any wave I convert (sound starts at the very beginning) to
AAC (-acodec aac) or MP3 ( -f mp3) has added 100ms of very low amplitude
noise in the beginning.

I ask: why? Why there must be 100 ms of noise at the beginning? Why can't
audio start at 0ms?

Sincerely,
Cebula Czosnek Pietruszka
