I bought the book you suggested to Kindle. So far seems very useful for getting the basics covered.Thank you for recommending it.
That breakdown of different sounds used in the SFX was extremely helpful! I knew it was combined of different sounds but didn't have any idea what kind of sounds were used. Definitely wouldn't have picked up the low drone and the ocean waves by myself.
Your explanation of the frequencies makes a lot of sense. It's basically the same as mixing a normal song, but with more aggressive EQ filtering. That's very interesting.
I tried combining those 4 kinds of sounds (synth, chimes, drone & ocean) quickly with the tips you gave. Definitely got some interesting results already. Nothing worth showing for and definitely not even close to Journey-level of awesome. Still, the result were far better than what I was able to achieve before your advice.
Thank you so much!
