NowSmart Audio Recorder turns cassette tapes, DVDs, and other external audio sources into audio files on your computer. The same steps work for keyboards, TVs, radios, and other devices with an audio output.

Step 1: Connect the device to your computer

Connect the player’s output to the Line In jack on your computer. The cable depends on the player’s output jack; common choices are an RCA to 3.5 mm stereo cable and a 3.5 mm to 3.5 mm stereo cable.

Other output jacks, such as 6.35 mm stereo and XLR, need a matching cable.

Connect the left and right Audio Out, or the headphone jack, of the external device to the Line In jack (usually blue) on your sound card.
