-==============================================

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

-Written by Jezar at Dreampoint - http://www.dreampoint.co.uk

-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.
