| | 7 | The fun part here is that if you go to the original video, https://www.youtube.com/watch?v=vUY-EH3gTRU, it does have the spike. This is the case for both format 251 opus and format 140 aac (and format 22, h264+aac, which can sometimes be different). But it might be a different-sounding spike, from a different source (audio level normalization during recording); it seems to give a peak dB of around 0 for both the webm/opus and mp4/aac, compared to the 14 dB peak when starting from the second audio packet of the attached file. |
