Abstract: Disclosed are various embodiments for detecting item scans with audio signal processing. A first machine-readable identifier may be rendered in a display device associated with at least one computing device, where the first machine-readable identifier is associated with a first item in a list of items. An audio signal may be captured using a microphone and analyzed to identify a predetermined tone in the audio signal indicative of a scan being performed on a register device. In response to the predetermined tone in the audio signal being identified, the first machine-readable identifier may be replaced with a second machine-readable identifier in the display device, where the second machine-readable identifier is associated with a second item in the list of items.
