Connect the 3.5mm output on the back of the SACD compatible amplifier to the computer's line-in jack. The line-in jack is usually light blue. Make sure the amplifier is set to output audio through the 3.5mm jack.
Alternative: Connect the RCA-to-3.5mm converter to the SACD player and 3.5mm cable if the SACD player supports RCA output.
Insert the SACD in to the SACD player and press play. Configure the output of the SACD player to two channels if it is supported.
Configure the computer's recording volume to make sure the recording volume is correct. In Windows 7, go to the Start Menu and click on "Control Panel." Select "Hardware and Sound" and click on the speaker icon or the "Sound" text. Select the recording tab, highlight the "Line In" option and select "Configure." Follow the on-screen instructions.
Open and configure the Audacity program for two-channel recording. Go to "Edit," "Preferences," and then the "Audio I/O" tab. Set the channels to the "2 (Stereo)" option.
Restart the track you want to record on the SACD player and press pause. Press the record button on the Audacity program. Press the "stop" button on Audacity when the track is complete. In Audacity, go to "File," "Export as MP3," and save the MP3 file to the computer.
