FFMPEG Bit Rate as 16Bit for Audio Conversion

Question

I am using FFMPEG Audio Converter to convert the file format. At Present it bit rate is 176.4 kbit/s, so it file size to big.

I want to convert it as possible at low bit rate but unable to find any solution.

I use below command line to convert the file

ffmpeg.exe -i "Audio Input FilePath" "Audio Output FilePath"

Just to clarify, you want 16 Kbit per second, not 16-bit PCM samples, correct? — Brad, Dec 23 '16 at 19:23
I only need to reduce the size of file . so i think when i reduce bit then it may reduce the size — Mitesh Machhi, Dec 26 '16 at 04:15

You can define with -b:a the target bitrate so try for example:

ffmpeg.exe -i "Audio Input FilePath" -b:a 64k "Audio Output FilePath"

rekire

still the same size and bit rate : 176 – Mitesh Machhi Dec 23 '16 at 06:58
try to add `-bufsize 64k` I thought that would be optional – rekire Dec 23 '16 at 07:01
If that won't work try `ffmpeg input.wav -codec:a libmp3lame -q:a 9 output.mp3` – rekire Dec 23 '16 at 07:04
now, bit rate set as 128.0 but size increased by 14 MB. original file size is 807 kb – Mitesh Machhi Dec 23 '16 at 07:25
yes i am using "ffmpeg input.wav -codec:a libmp3lame -q:a 9 output.mp3" this command and convert into WAV format – Mitesh Machhi Dec 23 '16 at 07:28
