Do you have questions about how to use the Zero Crossing Tool in Audacity? The Zero Crossing Tool ensures that the end points of the audio waveform you’ve selected are at the zero, or silent crossing point prior to editing the selection. This helps eliminate the possibility of popping sounds which can result from not using the Zero Crossing tool.
