user32832: i am new to video production , and i know that audio is a big part of the production process and cannot be messed up .
here is a audio that i recorded and then reduced the noise from audacity and exported
https://drive.google.com/file/d/1a5ZelYB6noyZhrVenkins0wZI62GC4Yj/view?usp=sharing
how can i further improve this audio

user31818: Audio is not my expertise, i try my best.
The problems of your source are

volume is low
speech is fast
sound is dull
bass is insufficient
treble is high

Therefore,

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

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

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

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

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.
