You could try the firequalizer filter

ffmpeg -y -i original.mp3 -af "firequalizer=gain_entry='entry(0,-23);entry(250,-11.5);entry(1000,0);entry(4000,8);entry(16000,16)'" test1.mp3

Each entry takes two parameters frequency and gain (dB). The gain for 0 Hz should be the bass value you used. The gain for 16000 Hz should be the treble value. 1000 Hz remains as is - no gain. 250 Hz gain should be half the bass value. 4000 Hz value should be half the treble value.

My ffmpeg has no such filter. fireequalizer. any other way – Santhosh Sep 21 '16 at 08:55
It's firequalizer with a single `e`. You need a version from March or newer. – Gyan Sep 21 '16 at 09:35

I tweaked it a bit to suit my needs. Worked like a charm! – Shovalt Oct 29 '17 at 08:36

I like this setting:

ffmpeg -y -i original.mp3 -af "firequalizer=gain_entry='entry(0,-8);entry(250,4);entry(1000,-8);entry(4000,0);entry(16000,-8)'" test1.mp3
