Look how long my hair is! As you can hear It was one of my first attempts to edit the soundtrack, add harmonies and etc. Something happened to the audio, because I converted it many times from one format to another, because I didn't know yet how it all should work and it also sounded differently in different players I used and it confused me even more. And the video editor also changed audio a bit. As well as I remember now, at the time I used audacity to record and edit the audio tracks, then I saved the file in plenty formats and converted them into another ones, choosed the best sounding one (using windows media player which is a culprit of strange sounding audio- now I know it). Next, I used to edit video using wondershare filmora and put it together with an audio track, save in mpeg4 format, aaand, If the audio still wasn't satisfying for me, I added audio again in windows movie maker. Oh My God, there was so many things to do. And it was taking soooo much time. Also the recording was time consuming , because I didn't know yet how to set my microphone and camera (aka my htc desire 610 on a tripod I made myself using tape, old camera tripod and clips).
Now it's a bit better, because I can sing harmonies way easier (back then I had to record them separately on piano and then sing, because I tend to miss many notes)- all those effords actually teached me a lot, It's actually a very good excercise. And I still use audacity, but now I know which format I should use, and for video editing I'm using sony vegas pro. And for recording I have my zoom h1 instead of novox nc1. Handy recorder is way more portable, and the quality is also better.
