You can import digital audio clips stored as audio files or tracks in video files. Digital audio is stored on computer hard disks, audio CDs, or digital audio tape (DAT) as binary data readable by computers. To keep quality as high as possible, transfer digital audio files to your computer via digital connections. Avoid digitizing the analog outputs from your audio sources through your sound card.
For maximum editing performance, Adobe Premiere Pro conforms each imported audio channel to 32‑bit floating‑point data at the project’s sample rate. All imported audio is conformed, even audio tracks in video files.
Using compressed audio formatsMusic stored in formats such as MP3 and WMA are compressed using a method that removes some of the original audio quality. To play back compressed audio, Adobe Premiere Pro must decompress the file and may need to resample it to match your output settings. These conversions are likely to degrade audio quality. For this reason, use an uncompressed or CD audio version of the audio clip whenever possible.
