The Recording Process

The process of recording through your sound card is the same whether you choose an analog or digital source, and the same process applies (with some minor variations) to any full-featured recording program and to both Macs and PCs. Following are descriptions of the key steps.

Making the right connection

To record from an analog source, the source must be connected to your sound card’s line input using the correct type of cable. Typically, this cable will have two RCA plugs on the end that connects to your stereo receiver or tape deck and a stereo 1/8” mini-phone plug on the end that connects to your sound card.

The most common type of digital interface for consumer audio equipment and sound cards is S/PDIF (Sony-Phillips Digital Interface). S/PDIF comes in a coaxial version that uses either RCA or 1/8” mini-phone connectors and in an optical version called Toslink that uses a fiber-optic cable with special optical connectors. In each case, all channels are transmitted through a single cable.

See Chapter 3 for more information on connecting your computer to your stereo system.

Setting audio parameters

Before you start recording, you must create a new file and specify the sampling rate, resolution, and number of channels (refer back to Chapter 8 for information about these parameters). In some recording programs you must choose these parameters when you create the file, while in other programs they are set automatically to default values unless you specify otherwise. ...
