If you use TRACK SEPARATION function, noise occurs.

Check the following.

1. Does your computer fulfill the environmental requirements of rekordbox?
   Check the System Requirements.
2. Is the buffer size properly adjusted?
   The latency (time that elapses before outputting sound after operating this equipment) can be shortened by setting the buffer size small.
