Importing digital audio
Premiere can import digital audio clips stored as audio files or tracks in video files. Digital
audio is stored as binary data readable by computers. Most digital audio is stored on computer
hard disks, audio compact discs (CDs), or digital audio tape (DAT). If you have capture
hardware that can read digital audio data directly, you can preserve the quality of your digital
audio source. Many computers in their standard configuration import audio through analog
input jacks; the digital audio is converted to analog when you use the audio equipment output
jacks and converted back to digital when you capture. This additional digital-analog-digital
conversion will reduce audio quality somewhat. If you require audio of the highest possible
quality, try to set up all-digital connections. Once the digital audio is in a format Premiere
can read, you can include it in your project using the Import command. See “Importing clips”
on page 120.
On Mac OS, you can import audio CDs tracks as AIFF files with no loss of quality, using a
converter built into QuickTime. Make sure you own the copyrights or have licensed the
copyrights to any CD tracks you use.
