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. -Technology Consultant -Dreampoint Design and Engineering -http://www.dreampoint.co.uk - - -//ends diff --git a/attic/muse_qt4_evolution/plugins/freeverb/revmodel.cpp b/attic/muse_qt4_evolution/plugins/freeverb/revmodel.cpp deleted file mode 100644 index c72ee22b..00000000 --- a/attic/muse_qt4_evolution/plugins/freeverb/revmodel.cpp +++ /dev/null @@ -1,232 +0,0 @@ -// Reverb model implementation -// -// Written by Jezar at Dreampoint, June 2000 -// http://www.dreampoint.co.uk -// This code is public domain - -#include <stdio.h> -#include "revmodel.h" - -//--------------------------------------------------------- -// Revmodel -//--------------------------------------------------------- - -Revmodel::Revmodel() - { - // Tie the components to their buffers - combL[0].setbuffer(bufcombL1,combtuningL1);
