Final answer:
The function that can be used to automate the isolation of a track is called track separation.
Step-by-step explanation:
The function that can be used to automate the isolation of a track is the track separation function. This function is commonly used in audio editing software to separate individual tracks or instruments from a mixed audio recording.
For example, in a music recording, if you have a mixed audio file with vocals, drums, guitar, and bass all combined, the track separation function can automatically separate each instrument into its own track. This allows for individual editing and processing of each track, resulting in better control over the final sound.
It's worth noting that track separation technology is constantly improving, but it may not always be perfect. Some tracks may be more difficult to isolate than others, especially if multiple instruments or vocals overlap in frequency range.
