Well, Industry Standard simply means what is the current most used DAWs in that particular industry worldwide. For example, ProTools is the current most used DAWs in the audio post/recording industry. And IMO, Logic is more commonly used by composer/arranger/song-writer than ProTools. Hence, one cannot compare them as in which is the industry standard. Coz although DAWs nowadays are pretty much simliar to one another, but each has it's own strong area, which can only define by the user themelves. Therefore, I always tell people that, one should not be bothered too much by this industry standard term when chosing a DAWs for yourself. Sometimes I may consider all these as market strategies to market their product. Most importantly is to choose one that serve your purpose, as well as, one you are most comfort with. But however, if you wish to develop a career in the audio engineering field, you have to know ProTools, coz most studio uses ProTools and if you don't it's hard to to employ.
Well, I uses ProTools since V6, but before I touched PT, I used many other DAWs like stuffs from Steinberg, Sonar, etc., and the moment I touched PT, I knew this is the one, I never wanna change, unless no choice. With ProTools 9 so affordable, and able to work without hardward or with third party hardware, what are you waiting for, make a switch and welcome to ProTools family man!
