First, we don’t know how the subs are compiled. What I mean is that some providers actually run scripts overlapped or accelerated already. And some scripts are dependent on one another or on the speed that our minds process one before being exposed to the next (which means you couldn’t run simultaneously). Unless we know exactly how the tracks are built, I wouldn’t recommend playing them faster.
Also, consider that running them faster changes the pitch a little, which may interfere. Running at 1000x would sound like the Earth’s atmosphere has been changed to Helium-dominant. Even though you can’t hear it, do you think the subconscious mind will take directions from Alvin and the Chipmunks?
Finally, there is a reason why the recommendation (in S-Clubs case) is to have up to 16 hours of exposure. Even though the subconscious mind can take in loads of data, that doesn’t mean it can process it all. Some of it gets back-logged. And thus requires recovery time. Accelerating your tracks may cause the “backlog” to fill up too much, at which point the mind may just choose to ignore the new cycles until it has made some room again. Which defeats your purpose.
As much as it annoys me that the subs aren’t so super-powerful that the subconscious can only bear to listen to them for a max of 2 hours a day instead of 16, there are simply too many unknowns and variables in the science.
That said, have you already trained yourself to listen and possibly read faster? I play TV episodes at 2.5x speed simply because normal speed is so ludicrously slow for me (yeah, I’m real fun at the movie theatre). I started at 1.2x and built it from there. Now I can do the same to audiobooks and music (although doing it with music is just plain weird, tropical house was not meant to be rave hardcore). One of the observations people have about speed reading is that the higher speeds actually help you get way more into it and amplify the creative mind. I notice the same with TV (and not just because the speed turns even procedural crime dramas into episodes of 24).
If you’ve trained yourself to do that, maybe you’ll be able to increase the speed of subs as well.
As for editing the track, I used to create blended tracks, merging the ultras with the masked. If you want to edit the files, remember to save as lossless and not MP3. Otherwise you stand the risk of recompressing something that was already compressed. No idea what that does to the effects. And as stated above, I’d recommend against alterations that change the wave at all, which includes accelerating it. Just use the player for that.
Final note (finally): feel free to experiment, just realize that no matter how awesome you are, change takes time. General consensus is about 21 days to breach the resistance barrier that makes up your habits and comfort zone. So find a way to measure the effect, make a change, then expose yourself for about a month before making another change. Measure and repeat. The scientific process is slow and tedious, but it works.
