Have mp3 files that were recorded in noisy environment
where there is a lot of low frequency hum, and the speaker's
voice is just barely about that noise's frequency.
It is really a great effort trying to comprehend what's being
said. The files are lectures from the late 60's and early 70's
and 80

I have an audio file which has the following specifications.
Codec: MPEG AAC Audio (mp4a)
Channels: Stereo
Sample rate: 44100 Hz
Bitrate: 253 kbps
It has both leading and trailing silence.
I want to remove the silences AND keep the quality intact.
So far I've tried
ffmpeg -i 1.m4a -af silenceremo

Hi,
My question is, how to blend or overlay transparent logo and video into video
with transparent effect by ffmpeg.
Transparent logo image is like the image with the below link. There is no color
in the background of the logo image, so the background is transparent.
