摘要：
A recording and/or reproducing apparatus includes a plurality of time base changing elements arranged to perform band compression and expansion by altering the time base of an incoming signal; a switching circuit arranged to selectively change audio signals inputted into and outputted from these time base changing elements from one over to another; and a recording-and-reproducing circuit arranged to record and reproduce the band compressed audio signal on and from a recording medium.
