How can i record me singing different parts of a song and then put them together?

To record yourself singing different parts of a song, you can use a digital audio workstation (DAW) like Audacity, GarageBand, or FL Studio. Start by recording the first part, then create a new track for each subsequent part you want to sing. After recording all the parts, you can edit and arrange them in the DAW, adjusting levels and adding effects as needed before exporting the final mix. Make sure to use headphones while recording to avoid bleed from the backing track into your vocals.
