+Freeverb - Free, studio-quality reverb SOURCE CODE in the public domain
+-----------------------------------------------------------------------

+Introduction
+------------
+
+Hello.
+
+I'll try to keep this "readme" reasonably small.
+There are few things in the world that I hate more than long "readme" files.
+Except "coding conventions" - but more on that later...
+
+In this zip file you will find two folders of C++ source code:
+
+"Components" - Contains files that should clean-compile
+      ON ANY TYPE OF COMPUTER OR SYSTEM WHATSOEVER. It should not be necessary
+      to make ANY changes to these files to get them to compile, except to make
+      up for inadequacies of certain compilers. These files create three classes
+      - a comb filter, an allpass filter, and a reverb model made up of a number
+      of instances of the filters, with some features to control the filters at
+      a macro level. You will need to link these classes into another program that
+      interfaces with them. The files in the components drawer are completely
+      independant, and can be built without dependancies on anything else.
+      Because of the simple interface, it should be possible to interface
+      these files to any system - VST, DirectX, anything - without changing
+      them AT ALL.
+
+"FreeverbVST" - Contains a Steinberg VST implementation of this version of
+      Freeverb, using the components in (surprise) the components folder.
+      It was built on a PC but may compile properly for the Macintosh with
+      no problems. I don't know - I don't have a Macintosh. If you've
+      figured out how to compile the examples in the Steinberg VST
+      Development Kit, then you should easilly figure out how to bring the
+      files into a project and get it working in a few minutes. It should
+      be very simple.
+
+Note that this version of Freeverb doesn't contain predelay, or any EQ.
+I thought that might make it difficult to understand the "reverb" part of
+the code. Once you figure out how Freeverb works, you should find it trivial
+to add such features with little CPU overhead.
+
+Also, the code in this version of Freeverb has been optimised. This has changed
+the sound *slightly*, but not significantly compared to how much processing
+power it saves.
+
+Finally, note that there is also a built copy of this version of Freeverb called
+"Freeverb3.dll" - this is a VST plugin for the PC. If you want a version for
+the Mac or anything else, then you'll need to build it yourself from the code.
+
+
+Technical Explanation
+---------------------
+
+Freeverb is a simple implementation of the standard Schroeder/Moorer reverb
+model. I guess the only reason why it sounds better than other reverbs,
+is simply because I spent a long while doing listening tests in order to create
+the values found in "tuning.h". It uses 8 comb filters on both the left and right
+channels), and you might possibly be able to get away with less if CPU power
+is a serious constraint for you. It then feeds the result of the reverb through
+4 allpass filters on both the left and right channels. These "smooth" the sound.
+Adding more than four allpasses doesn't seem to add anything significant
+to the sound, and if you use less, the sound gets a bit "grainy".
+The filters on the right channel are slightly detuned compared to the left channel
+in order to create a stereo effect.
+
+Hopefully, you should find the code in the components drawer a model of
+brevity and clarity. Notice that I don't use any "coding conventions".
+Personally, I think that coding conventions suck. They are meant to make
+the code "clearer", but they inevitably do the complete opposite, making
+the code completely unfathomable. Anyone whose done Windows programming
+with its - frankly stupid - "Hungarian notation" will know exactly what
+I mean. Coding conventions typically promote issues that are irrelevant
+up to the status of appearing supremely important. It may have helped back
+people in the days when compilers where somewhat feeble in their type-safety,
+but not in the new millenium with advanced C++ compilers.
+
+Imagine if we rewrote the English language to conform to coding conventions.
+After all, The arguments should be just as valid for the English language as
+they are for a computer language. For example, we could put a lower-case "n"
+in front of every noun, a lower-case "p" in front of a persons name,
+a lower-case "v" in front of every verb, and a lower-case "a" in front
+of every adjective. Can you imagine what the English language would look like?
+All in the name of "clarity". It's just as stupid to do this for computer
+code as it would be to do it for the English language. I hope that the
+code for Freeverb in the components drawer demonstrates this, and helps start
+a movement back towards sanity in coding practices.
+
+
+Background
+----------
+
+Why is the Freeverb code now public domain? Simple. I only intended to create
+Freeverb to provide me and my friends with studio-quality reverb for free.
+I never intended to make any money out of it. However, I simply do not have the
+time to develop it any further. I'm working on a "concept album" at the moment,
+and I'll never finish it if I spend any more time programming.
+
+In any case, I make more far money as a contract programmer - making Mobile
+Internet products - than I ever could writing plugins, so it simply doesn't
+make financial sense for me to spend any more time on it.
+
+Rather than give Freeverb to any particular individual or organisation
+to profit from it, I've decided to give it away to the internet community
+at large, so that quality, FREE (or at the very least, low-cost) reverbs can
+be developed for all platforms.
+
+Feel free to use the source code for Freeverb in any of your own products,
+whether they are also available for free, or even if they are commercial -
+I really don't mind. You may do with the code whatever you wish. If you use
+it in a product (whether commercial or not), it would be very nice of you,
+if you were to send me a copy of your product - although I appreciate that
+this isn't always possible in all circumstances.
+
+HOWEVER, please don't bug me with questions about how to use this code.
+I gave away Freeverb because I don't have time to maintain it. That means
+I *certainly* don't have time to answer questions about the source code, so
+please don't email questions to me. I *will* ignore them. If you can't figure
+the code for Freeverb out - then find somebody who can. I hope that either
+way, you enjoy experimenting with it.
+
+
+Disclaimer
+----------
+
+This software and source code is given away for free, without any warranties
+of any kind. It has been given away to the internet community as a free gift,
+so please treat it in the same spirit.
+
+
+I hope this code is useful and interesting to you all!
+I hope you have lots of fun experimenting with it and make good products!
+
+Very best regards,
+Jezar.
