Hi, In audacity to select some audio so that you can apply an effect, you have to select one or more tracks, and a time range. So in your case where you want to apply an effect to all the audio in one of the tracks, then: 1. Make sure that the desired track is selected, and the other one is not selected. (pressing enter toggles whether a track is selected). 2. Select a time range which covers all the audio in the selected track. To do this press J to move the cursor to the start of the audio in the select track, and then press shift+K to move the end of the selected time range to the end of the audio in the selected track. 3. apply the effect.
Note that you can also change speed using the "sliding time scale/pitch shift effect", if you set the initial and final tempo change settings to the same value. This effect produces better quality audio, but takes longer. When you say "picture fact broken", what do you mean by this? For your information there's an Audacity4Blind mailing list on freelists: http://www.freelists.org/list/audacity4blind And there'a also a guide to Audacity for jaws users, which is also nearly all applicable to users of nvda and window-eyes: http://vip.chowo.co.uk/wp-content/uploads/jaws/Audacity-2.1.0-Guide.html David. original message: Hi, I have to music tracks. I need to change the tempo of one of them. Every time I try to change the tempo, both of them change tempo. What am I doing wrong? And why is a picture fact broken? I can't get it to work.
