This is a collection of resources that I've found helpful over the years. My focus is game audio specific, so your mileage may vary.
Good reference for getting up to speed with modern C++. Requires background in programming.
Huge amount of helpful information packed into a single book. Might be a bit dated now, was a great buy whilst I was studying at university.
Even in it's unfinished state this is a great resource about interactive acoustics. I'd love to see Lauri Savioja finish this.
Targetted at live sound. Was another great buy when I was studying at university.
Lots of very knowledgeable members and discussion. The mailing list is pretty quiet now, but the archives are online and useful too.
Mailing list for working professionals in game audio. The mailing list has a huge reach. A bit quieter than it used to be.
