superimpose audio on stream

Hello, I'd like to overlay the audio waveform coming from an axis camera's stream. I've started to read the documentation, but It's quiet complex. For testing I use that bunny stream. So far I managed to pad a bottom: #!/bin/bash stream="rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov" padbottom=40 ffmpeg -i "$stream" -vf "pad=width=240:height=160+$padbottom:x=0:y=0:color=black" outfile.mp4 I'd like similar to this video: https://www.youtube.com/watch?v=BG9SYC0wWYw Could you please help me? Thanks, Zolee
