Ask HN: any hackerlike ways to train your singing when alone with no feedback? I will try to search algolia and come back to you with my research
sudo apt install audacity
('audacity' is a sound recording program.) Then try to sing along a YouTube song, listening to the song in your headphones, whilst singing into a mic — recording your voice only.Then play back your voice, from the recording, and find out what you'd like to change about your voice, and what you can get better at. It's harder to sing, than what I thought!
And, juts like running or table tennis or whatever, everyone is going to be not-good at it, in the beginning, I think.
