I think you'll find that your experience of my Latitude horn will vary, depending on the quality of your sound system.
But, the reason that I didn't produce a replacement sound for Titanic when Fred and I worked on the Add-on sounds was that following a lot of research, I decided that the existing Titanic horn was already pretty close to the likely sound of the original.
What you hear from a film will not be authentic, believe me. What you have on your phone will
(a) not be good enough quality
(b) not be realistic
(c) not be legal to copy.
BE WARNED: Regretably, I would have to delete the sound from this forum and ban the person posting the sound. (breach of copyright is theft, usually).
