Hi I work with song production and audio editing, and I'm new here.
The software to use in this case to clean up interference or noise and change the speed of the playback, in my point of view would be Soundforge 10
and Sonar x1 with some waves plugins.
But the original source probably would be better to work than a capture from youtube, since youtube audio is at 22khz (except if in HD ), a half way
then cd quality that is 44.1 khz, and in this conversion to a lower bitrate generally the audio became poorer and in bad quality than original.
I will try clean and try a lot of speeds of playback so if I find something I will post here in a week. If you did n't hear anything in a week I will
have found nothing.
