Hi everyone! Few months ago I started to post some musics online and I would love to have some advices to improve myself. I don't have a powerful voice but I think it's correct, but I would like to know what can I do to improve! I'm also recording with an USB mic and I would like to have an XLR one but I don't know what microphone to buy for a low budget. Here's one of my song! Thank you!
