how can i further improve this audio

Answer 1

Audio is not my expertise, i try my best.

The problems of your source are

1. volume is low
2. speech is fast
3. sound is dull
4. bass is insufficient
5. treble is high

Therefore,

1. I use the command to find the max volume

   ffmpeg -i source.wav -af "volumedetect" -vn -sn -dn -f null /dev/null
   , which is -6.4dB, then i transform the max volume to 0dB by using audio filter volume=6.4dB

2. I slow down the speech by using audio filter atempo=0.8

3. I make it lively by using audio filter aecho=0.06:0.9:50:0.7

4. I boost the bass by using audio filter firequalizer=gain_entry='entry(0,24);entry(250,12);entry(500,4);entry(1000,2);

5. I decrease the treble by using audio filter firequalizer=gain_entry='entry(4000,-4);entry(16000,-20)'

In conclusion, the command is

ffmpeg -y -i source.wav -af "\
volume=6.4dB,\
atempo=0.8,\
aecho=0.06:0.9:50:0.7,\
firequalizer=gain_entry='\
entry(0,24);entry(250,12);entry(500,4);entry(1000,2);\
entry(4000,-4);entry(16000,-20)'" \
output.wav

Hope you like it, good luck.
