Like most, if not all creative vocations, there is always something new to learn in the world of sound recording and mixing. All of my tutors over the years have told me that they are still learning new things in the studio, even those who have been in the industry for decades. This is what keeps things fresh and interesting, it’s what creative people thrive on!
Of course, it’s important to know how to correctly use a compressor, gate, reverb or delay: To learn what each control does and how it effects the audio you are treating. But, it’s also important to ignore all the rules and experiment every now and then. In the modern world of DAWs and Plugins, it’s a lot easier to chain a bunch of effects together, turn their dials and come up with some weird and wonderful effect… Once in while, it might even be useful in a mix 🙂 Don’t be afraid to try it for yourself… Happy accidents will happen from time to time and you’ll have learnt a new technique in the process 🙂
Finally, don’t think that you can’t learn something new from anyone and everyone around you. From the seasoned pro to the novice bedroom mixer, they all have the potential to teach you something new, something that you might never have thought of by yourself. New dogs CAN teach old dog new tricks if their minds are open!
