It looks like you're looking for a version of a .rar file related to Transmission IV by Porcupine Tree.

Originally released in December 2001, Transmission IV was the final installment in a series of limited-edition releases exclusive to the band's information service subscribers. It is often considered the "holy grail" for fans of Porcupine Tree's early space rock era.

: A dedicated fan or "taper" eventually secured one of the rare physical CDs and performed a high-quality secure rip using EAC (Exact Audio Copy). They re-uploaded it with the suffix "fixed" to signal to the community that the audio was finally seamless.

If you have found the "fixed" version, you are hearing the track as it was meant to be heard: a seamless, uninterrupted transmission from one of modern prog’s most creative minds.
