Dear co-authors,
I edited my single titled Girl from the North using audacity.
During the saxophone solo there is clearly a sharp click audible, a mistake by the music studio manager. Is it possible to remove this with audacity?
Is it also possible to lower very high sound tones that sound too sharp?
Thanks in advance.
grtz,
Gilbert

You only attached a jpeg image, (the artwork), not a sound-file.
Is it also possible to lower very high sound tones that sound too sharp?
Do you mean musically-sharp with the pitch too high?
Or just “harsh”, with the high frequencies too strong/loud?
The [u]Equalizer[/u] can be used to adjust the volume of selected frequency bands. The high frequencies are on the right and low frequencies on the left. (For “experimenting”, I recommend the Graphic EQ mode.)
…Pitch correction of selected notes is more complicated.
