	Message written at 13 Nov 1998 11:44:56 +0000 If the need to preserve old orchestras and the need to provide clear service to newcommers are both to be accommodated, then it woudl be possible to have a command-line option or environment variable to select old or new. A little more messy internally but doable. As it has been brought up, are there any strong feelings about converting all the newer noise opcodes to be self contained and indepenent? I see some dangers in this as it may lead to each note repeating the same numbers. I think it would be possible to arrange a tri-state for seeding; (1) take this seed (2) use last value (3) creat from clock or somewhere Just musing; this change would break my chapter in the book. ==John ffitch Received: from stork.maths.bath.ac.uk by omphalos.maths.Bath.AC.UK id aa04317; 13 Nov 98 13:46 GMT Received: from mercury.bath.ac.uk by stork.maths.Bath.AC.UK id aa09585; 13 Nov 98 13:46 GMT Received: (qmail 9815 invoked from network); 13 Nov 1998 13:46:13 -0000 Received: from hermes.ex.ac.uk (HELO exeter.ac.uk) (144.173.6.14) by mercury.bath.ac.uk with SMTP; 13 Nov 1998 13:46:13 -0000 Received: from noether [144.173.8.10] by hermes via SMTP (NAA06869); Fri, 13 Nov 1998 13:28:50 GMT Received: from exeter.ac.uk by maths.ex.ac.uk; Fri, 13 Nov 1998 13:28:37 GMT Received: from first1.lnk.telstra.net [139.130.48.118] by hermes via ESMTP (NAA11971); Fri, 13 Nov 1998 13:28:24 GMT Received: from wira (wira.firstpr.com.au [203.36.57.201]) by gair.firstpr.com.au (8.8.7/8.8.7) with SMTP id XAA27173 for ; Fri, 13 Nov 1998 23:29:44 +1100 Message-Id: <199811131229.XAA27173@gair.firstpr.com.au> From: Robin Whittle Organization: First Principles To: Csound list Date: Sat, 14 Nov 1998 00:24:02 +1000 MIME-Version: 1.0 Content-type: text/plain; charset=ISO-8859-1 Content-transfer-encoding: Quoted-printable Subject: 31 bit PRNG for x-class noise ugens Priority: normal X-mailer: Pegasus Mail for Win32 (v3.01b) Sender: owner-csound-outgoing@maths.ex.ac.uk Precedence: bulk I tackled this random number business in July. Take a look at: http://www.firstpr.com.au/csound/ and scroll down to the heading: "1 - Adding a better Random Number Generator to Csound" I installed a single 31 bit Park-Miller Pseudo Random Number Generator (PRNG) for use by all the "x-class noise" ugens. There is a seed ugen for that PRNG: such that if the input paremeter to the seed opcode is 0, then the time of day will be used, and if it is anything else, then the seed is used to three decimal places, with a range of any positive or negative number to a maximum value of +/- 2,147,483.645. Input above this is treated mod 2,147,483.645. The new system runs marginally faster (28% on my Linux PPro machine) than the internal C library PRNG rand() function. I also added functions in cmath.c and lines in entry.c to implement three new bipolar uniform random opcodes: ibunirand, kbunirand and abunirand. ir ibunirand irange kr kbunirand krange ar abunirand krange These behave just like the xbunirand opcodes (erroneously called xuniform in the current manual) except that their ouput range is positive and negative, rather than positive from 0 to xrange. For instance: ar abunirand 100 will write evenly distributed random numbers - ie white noise - in the range -100 to +100. The source code and patch files to achieve the changes are all at my site, in the directory: http://www.firstpr.com.au/csound/rand31/ An updated version of the x-class noise page of Jean Pich=E9's HTML manual is at: http://www.firstpr.com.au/csound/rand31/xnoise.html I haven't done any Csounding for a while, but what I did a few months ago, I did use these features. These changes have also been incorporated in the [Infamous - or whatever the name is to distinguish it from John Fitch's] Linux version of Csound as maintained by Nicola Bernardini . Matt J.

That's exactly what I have been doing. All the random elements of a piece= use the x-class-noise ugens and therefore depend entirely on the single seed. = I have made mulitple versions of the one piece with multiple seeds (chosen f= or instance by rolling dice or whatever) and then I can listen to them and de= cide which ones I like.

My changes do not affect backwards compatibility. See my site for a revie= w of the various random number subsystems in Csound - its not a pretty sight, a= nd I may have missed something. Apart from the x-class-noise ugens, I leave th= em all alone: I leave the source code alone and don't use the ugens. - Robin =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Robin Whittle rw@firstpr.com.au http://www.firstpr.com.au Heidelberg Heights, Melbourne, Australia First Principles Research and expression: music, Internet music marketing, telecommunications, human factors in technology adoption.

There will be new information about this shortly, on our website: http://www.bath.ac.uk/~masjpf/CDP/CDP.htm One aspect of 24/32bit files is that those who are really concerned about the ultimate audio quality will want their final files dithered down to 16/20 bits or whichever. I have found one freeware dither application on the net, but it does not(yet?) know about Type 3 floatsam files, only 24bit PCM. Does anyone have a dither or noise-shaping algorithm they fancy donating to Csound? I suppose this might involve adding yet another flag to the Csound commandline - but just think of the possibilites if Csound adopts Unicode!

If I correctly understand what you're after I think I have accomplished this by using "Virtual Audio Cable", the blurb of which is attached below. Joel -----------------------------------attachment------------------------------ Virtual Audio Cable Driver 1.00 =============================== Author: Eugene Muzychenko, Novosibirsk, Russia 2:5000/14@FidoNet, music@spider.nrcde.ru Introduction ------------ The Virtual Audio Cable embodies an idea of physical interconnection cable applied to Windows digital sound devices (Wave In and Wave Out). Driver creates a pairs of Wave In/Out device ports; "In" and "Out" devices in each pair are internally connected so all digital audio data sent (played) to "Out" part of the cable by one program is directly transferred to the "In" part and can be retrieved (recorded) by another program. This mechanism allows to interconnect several programs that are using Wave devices - software synthesizers, sound processors, sound editors, sequencers etc. Additionally, it allows to record pure digital audio data produced by programs that don't create WAV files, sending audio only to Wave device in real time. Installation ------------ If driver files are packed, first unpack the archive to any empty directory on your hard disk. In Windows 95, go to the Control Panel, double click "Add New Hardware" icon, answer "No" to auto search prompt, then select "Sound, video and game controllers". In device list dialog select "Have disk" and enter a path to the driver directory. Select "Virtual Audio Cable Device Driver" and follow instructions displayed. In Windows 3.1, go to the Control Panel, double click "Drivers" icon, select "Add", then "Unlisted or updated driver", enter a path to the driver directory and select "Virtual Audio Cable Device Driver". Windows restart is required to activate installed driver. * WARNING * Driver designed to run in Windows 3.1 or above but tested only under Windows 95. In Windows 3.x some problems may appear. After system restart, there appears a new Wave Device "Virtual Audio Cable", having two Digital Audio ports: "Audio Cable 1 In" for input port and "Audio Cable 1 Out" for output port. Driver supports up to eight independent cables; actual number is represented by "NumberOfCables" entry of "[Virtual Audio Cable]" section of Windows SYSTEM.INI file. This entry with initial value of 1 is appended to your SYSTEM.INI during the installation process. You can edit this file using SysEdit or any other text editor like NotePad, and manually change this value in range 1..8, making desired number of cables. Don't forget that Windows restart is required to take effect of the changes. Working with cables ------------------- Both cable sides are standard Windows wave devices, you can use "In" and "Out" ports of each cable with any program that works with audio devices. All cables are completely independent. Both sides of one cable must be open with same format: if other side isn't open, each device accepts any wave format; when other side is open with given format, device accepts only same format. Virtual cable behaves as a real cable: - when only output side is open, all played data is ignored; - when only input side is open, silence is recorded; - when both sides are open, all data sent to output side appears unchanged at input side. All internal data transfers from output to input side are completely digital, and no quality degradation occurs. If you play WAV file to output side and simultaneously record data from input side, all recorded data will be same as played, except of possible leading and/or trailing silence. Removing the driver from your system ------------------------------------ To remove driver from system you can select "Remove" in Control Panel or simply delete "wave=vac.drv" line from [drivers] section of SYSTEM.INI. Additionally, you can delete the "[Virtual Audio Driver] section. After Windows restart you will be able to delete driver file VAC.DRV from Windows SYSTEM directory. Obtaining new versions of the driver ------------------------------------ If new versions or bug fixes are released, they will be placed at ftp://spider.nrcde.ru/pub/sound/other/vac.zip.

I recommend as strongly as I can that random variables be truly independent. This means all "random" variables should be based on one single underlying pseudo-random variable (linear congruential operator, usually). In C++ terms, this would mean that all random variable objects contain a single static instance of a linear congruential operator or other pseudo-random variable. As for seeding, the underlying operator should seed itself from the time when the library is initialized. After that, it should have a call so that the user can reseed it. You can imagine what would happen if two random variables with separate operators were each used to produce their own streams of notes. If the user reseeded the supposedly independent variables with the same seed before use, they would generate identical streams of notes. Hardly random! I feel that if users have come to depend upon the variable producing a certain sequence, it is hardly something that could be called "random". It is always possible to code one's own linear congruential operator if such a predictable sequence is desired; the algorithm is simple. -----Original Message----- From: jpff@maths.bath.ac.uk To: csound@maths.ex.ac.uk Date: Friday, November 13, 1998 8:25 AM Subject: Random, old and new >Message written at 13 Nov 1998 11:44:56 +0000 > >If the need to preserve old orchestras and the need to provide clear >service to newcommers are both to be accommodated, then it woudl be >possible to have a command-line option or environment variable to >select old or new.
