As some of you here know, I have been involved with fractint and its sound producing feature for many years - off and on since the early 1990s. I have always been intrigued with watching the orbits as each point is calculated and listening to the sounds produced by the results of each of those orbital calculations. The earliest iterations of the fractint program only allowed for very rudimentary sounds via the PC speaker - basically buzzes. Back in those days there very few sound cards and they were very expensive and difficult to configure - basically, computers then were just not powerful enough to handle sound adequately and recording to disk was very problematic...i/o just wasn't fast enough. My first recordings were actually made by pulling the PC case off my trusty 286 and dangling a cheap-o Tandy mic (attached to a hand held cassette recorder) over the speaker. My very earliest recordings had audible background noises like TV, dogs, wife, etc. to go with the fan noise. Awkward and ugly. So I was forced to upgrade to a 386w/math coprocessor and a Gravis sound card. Fractint still didn't use the soundcard, but I was able to record. But I wanted more flexibility with the sound and decided that if I could somehow convert .wav files to midi that I could use different midi instruments for playback. I know some of you may be laughing at that desire to do .wav->.mid conversion - I didn't know any better. The fractint development team came to my rescue and we worked to get the orbitsave=sound parameter implemented. Utilizing that feature I was able to sledgehammer together a program that converted that output, utilizing a program I wrote (long lost to hd failure and faulty backups) to produce midi files from fractint output. It was a year long project, the results of which became the "Sounds of Chaos" CD which you can listen to via my audio fractal site. <https://sites.google.com/site/audiofractals/mp3-files/Sounds_of_Chaos_CD> During that same approximate time period the fractint dev team - primarily Tim Wegner, Jonathan Osuch and Robin Bussel - were busy integrating the capability of using sound cards for output, in addition to the pc speaker. This opened up a huge number of sound variables to be played with. I find this output to be far more exciting and "organic" than midi instruments and have thus not tried to resurrect my midi conversion program. As Windows became less and less DOS-friendly my interest in pursuing audio fractals waned and until recently I have done nothing new since around 2003. DOSBox SVN-Daum has changed all that! I'm having fun again and plan to start regularly doing new audio fractals. I hope that there is some modicum of interest in fractint sound somewhere. At least I hope that some of you will take the time to do a bit of exploring with me as I post links and pars. A lot of my older files don't have the par file from which they came associated with them any more. However, all my new ones will be posted as mp3 files along with the fractint par file which was used for the basic sound. Many of them can be run with good results, especially if combined with some atmospherics, such as reverb, concert hall, etc. Cheers!
