Play-only devices like CD- or MP3 players cannot be measured as traditional 4-pole devices. Therefore traditional transfer function measurements using the generator part of the audio analyzer are not possible. Those devices are tested with a pre-recorded test signal available as wav or MP3 file. This application note describes a fast test together with a setup and an executable which runs the test and displays the desired results. The test signal is provided as a linear coded wav file. This file can easily be coded into MP3 format using any commercially available or public domain wave editors or ripper programs. The test can also be executed by IEEE control and all results can be read out by IEEE commands.
