My computer and its version is Mac OS Sierra, Ver. 10.12.4. The version of Audacity is 2.1.3.
I am copying music cassettes to CDs. I use a Cassette2USB Converter. Many of the cassettes transfer very well to the CDs. Others, however, do not play back satisfactorily. During playback I can hear both sides of the cassette tape simultaneously. I can convert one cassette to a CD and it works fine. But the next one I convert may be the one on which I can hear both sides of the tape at once.
Can you tell me what is happening and how to correct it?
