I share the code https://colab.research.google.com/gist/xer-rex/fc1ea362f27699cfe2375d71332a0a10/audio_transform.ipynb

you can just do the playback on output.wav

i don't think that the audio has a lot of reverb or echo(idk the difference between reverb and echo) it would be helpful if you could check if it is same in your system. My desired result is something suitable for Youtube :)

The aecho document is https://ffmpeg.org/ffmpeg-filters.html#aecho; it might help you get to the point of your "desired result", or not. I have no further comments on the subjectivity of hearing.

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.
