Apply effects on your audio. By playing with the sliders, you can get a squirrel or evil voice. You can also export your adjusted song & share with friends or listening in another player. Pitch change in semitones: -------------------------- A value smaller than zero means that the resulting key is lower than the original key (and vice-versa). A value of zero means that the key is not changed. One full step corresponds to one semitone. Decimals can be used for fine adjustments (for instance for non-western music styles). Example: a change of -12 semitones means that the song is played one octave lower. Playback speed: --------------- A value smaller than 1.0 means that the speed is reduced while a value greater than 1.0 means that the playback speed is increased. A value of 1.0 means that the speed is not changed.
