[Csnd] Ftable Memory Limit

Date	2026-01-04 18:03
From	Michael Rhoades
Subject	[Csnd] Ftable Memory Limit
	Greetings All, I need to generate a 1-second-long audio waveform based upon an ftable of size 48,000 and then eventually a 10-second-long waveform, size = 480,000. As a proof of concept, I began with a table size of 50, just to make sure I had the syntax correct, and that worked fine. For the next step I tried an ftable with a size of 4800 and it crashes Csound. When I run it from command line it ends with an error, "out of memory". I am using Csound version 6.05. Is this an issue in later versions of Csound 6.x? Is version 7 capable of working with extremely long ftables? Thank you very much for any assistance or information you can provide and Happy New Year!!

Re: [Csnd] Ftable Memory Limit

That seems really odd even for older versions. Table size limit for 6.x is 2^24, at 48k it's a little over 349 seconds, about 5.8 minutes of mono audio.

Can you post a simple example showing the issue?

Hi Victor,

Yes, I can. I would love to find out I am simply doing something incorrectly!

Please find attached, the pertinent files. I hope attachments are acceptable for the listserve. If not, I can copy and paste it in response, but the ftable is quite long for that.

Thanks so much for looking into this.

Michael

Re: [Csnd] [EXTERNAL] [Csnd] Ftable Memory Limit

There is no gen 1 table, but there is an i statement:

;

inst

start

idur

ifn

0.1

I do see that it was missing a space in the ftable. It should be:

f 1 0 4800 8 1

It is a tab delimited file best viewed in Excel or similar spreadsheet format. (I work with all my scores that way.) Should I put a copy of this in a Google sheet so I can see what you are seeing?

Subject	Re: [Csnd] [EXTERNAL] [Csnd] Ftable Memory Limit
	What I figured out is that it’s not to do with size of the table but with the number of arguments. In Csound 6.x, there was a max number of pfields, and anything more got an extended argument list. It seems that this was not implemented correctly. In Csound 7 there is no max number of pfields. best ======================== Prof. Victor Lazzarini Maynooth University Ireland > On 4 Jan 2026, at 20:58, Michael Rhoades wrote: > > Excellent Victor.

	Victor, I found a Windows installer for beta Csound 7.0. It does render a sound file for the 50-argument ftable. Extremely quickly! And it works as expected. However, when I run the same .orc and .sco commenting out the 50-argument ftable and uncommenting the 4800-argument ftable (nothing else changes), this is the output: PS E:\Current Projects\2026(0) - Quantum Computational Creativity\csound> csound orc\03a.orc sco\03b.sco -o sfdir\Render_012.wav warning: could not open library 'C:\Program Files\Csound7\plugins64\\osc.dll' (-1) --Csound version 7.0 (double samples) Nov 10 2025 [commit: d31e30d1288328326275b475a6b9b27b9344c1a3] orchname: orc\03a.orc using callback interface Compiling Csound code... ...done Elapsed time at end of code compilation: real: 0.005s, CPU: 0.006s Am I using the same beta version of Csound 7 that you are?

Subject	Re: [Csnd] [EXTERNAL] [Csnd] Ftable Memory Limit
	Hi Victor, Yes, it is the Nov 10 version. I was unable to find a windows installer at the link you sent but I may not understand where to look for it. I tried the -n flag, and nothing changed. Ctl-c is not helpful because the command executes so quickly and closes. The only thing that prints on the terminal when I try to run it is what I sent you. Very strange that it is not completing for me but it did for you. Is there a possible dependency missing? I need to get to the bottom of this but not sure what the next troubleshooting step is. Can you send me the sound file you were able to render? It would be good to verify that it was the one in question. thx, Michael From: A discussion list for users of Csound <CSOUND@LISTSERV.HEANET.IE> on behalf of Victor Lazzarini <000010b17ddd988e-dmarc-request@LISTSERV.HEANET.IE> Sent: Monday, January 5, 2026 1:56 AM To: CSOUND@LISTSERV.HEANET.IE <CSOUND@LISTSERV.HEANET.IE> Subject: Re: [Csnd] [EXTERNAL] [Csnd] Ftable Memory Limit You are running a version from Nov 10, I am running the latest.

	I will do. The sound I get is very short but it's what I was expecting. I also get a printout of the table in ascii. It's all there. Meanwhile the reason you could not find the artefacts in that link is probably because you are not logged into GitHub. You need to make an account to access those files. If there were missing dependencies, Csound would not start. I would expect a crash to give some printout, but Windows might be different.

Subject	Re: [Csnd] [EXTERNAL] [Csnd] Ftable Memory Limit
	Thanks again for checking into this Victor. If the sound file is short, then it is not the ftable I am having the issue with. It should be 1 second in length, 4800 amplitude values with intervals of 1. The shorter sound file, consists of 10 repeating waveforms... if memory serves it is .095 seconds in length, 50 amplitude values. I am not sure what to think. FYI, I am conducting research into Quantum Computational Creativity. In this second phase, the execution of the quantum circuits is actually creating the waveforms. The first phase of the project is documented in the link below. It is a sonification of the wavefield interference patterns while 10 qubits are in superposition. Of course, there is no way to measure them because they collapse when measured, but they are inferred by the characteristics of the collapsed state. https://perceptionfactory.com/quantum-computing-sonifications/ Michael From: A discussion list for users of Csound <CSOUND@LISTSERV.HEANET.IE> on behalf of vlz <viclazzarini@GMAIL.COM> Sent: Tuesday, January 6, 2026 2:03 AM To: CSOUND@LISTSERV.HEANET.IE <CSOUND@LISTSERV.HEANET.IE> Subject: Re: [Csnd] [EXTERNAL] [Csnd] Ftable Memory Limit I will do. The sound I get is very short but it's what I was expecting. I also get a printout of the table in ascii. It's all there. Meanwhile the reason you could not find the artefacts in that link is probably because you are not logged into GitHub. You need to make an account to access those files. If there were missing dependencies, Csound would not start. I would expect a crash to give some printout, but Windows might be different.

I was unable to find a windows installer at the link you sent but I may not understand where to look for it. I tried the -n flag, and nothing changed. Ctl-c is not helpful because the command executes so quickly and closes. The only thing that prints on the terminal when I try to run it is what I sent you. Very strange that it is not completing for me but it did for you. Is there a possible dependency missing? I need to get to the bottom of this but not sure what the next troubleshooting step is. Can you send me the sound file you were able to render? It would be good to verify that it was the one in question. thx, Michael From: A discussion list for users of Csound <CSOUND@LISTSERV.HEANET.IE> on behalf of Victor Lazzarini <000010b17ddd988e-dmarc-request@LISTSERV.HEANET.IE> Sent: Monday, January 5, 2026 1:56 AM To: CSOUND@LISTSERV.HEANET.IE <CSOUND@LISTSERV.HEANET.IE> Subject: Re: [Csnd] [EXTERNAL] [Csnd] Ftable Memory Limit You are running a version from Nov 10, I am running the latest.

In Csound 6.x, there was a max number of pfields, and anything more got an extended argument list. It seems that this was not implemented correctly. In Csound 7 there is no max number of pfields. best ======================== Prof. Victor Lazzarini Maynooth University Ireland > On 4 Jan 2026, at 20:58, Michael Rhoades <mrhoades@PERCEPTIONFACTORY.COM> wrote: > > Excellent Victor.

As a proof of concept, I began with a table size of 50, just to make sure I had the syntax correct, and that worked fine. For the next step I tried an ftable with a size of 4800 and it crashes Csound. When I run it from command line it ends with an error, "out of memory". > > >> > > >> I am using Csound version 6.05.
