[FFmpeg-user] How to enforce VBR minimum bitrate

[sooksin at expressinmusic.com]

Hi experts!

 

I am currently using ffmpeg as a solution to audio file conversion and
normalization.

 

I understand that my setting (-q:a 5) below should produce output with
bitrate range in between 120-150kbps, or sometimes even lower than that if
the input already in being a lower bitrate than requested.

 

By using VBR Encoding, is there an option that is able to constrain the
bitrate minimum at 128kbps?

 

ffmpeg -i "input" -af "silenceremove=0:0:0:-1:1:-80dB,
dynaudnorm=p=1:m=3:r=1" -vn -acodec libmp3lame -q:a 5 -ar 44100 "output.mp3"

 

Please kindly advise. Thanks!

 

Regards,

Sook Sin
