	I think we should play with oscil3 for a few months and see what, if anything, it does to the only part of us that counts in this regard - our ears. If it makes a difference, as I suspect it might, I would prefer to retain oscili and add oscil3, or perhaps to change oscili and add oscil2. -----Original Message----- From: J.P.Fitch@bath.ac.uk To: csound@maths.ex.ac.uk Date: Monday, January 04, 1999 1:36 PM Subject: Cubic interpolation >Message written at 4 Jan 1999 16:35:01 +0000 > >I have added to my experimemtal system a family of opcodes which are >like oscili except that they use cubic interpolation.

Adjusting an opcode is not trivial, and certainly is Oversampling waveform tables in order to avoid the birdies is less a problem, than oversampling sound files, which runs into the problem of having the storage space for the sound and the access to SR conversion routines. I think hifi interpolation is most needed in any opcodes which pitch shift sound files, particularly if the shifting is dynamic as in these cases the foldover becomes most apparent. (I have actually resorted to 2X and 4X oversampling sound files with adjusted indexing to avoid this problem, a total kludge.) Hifi interpolation opcodes will most definitely be useful in these cases. Towards this (my vote), I think a cubic interpolating tablei (tablei3 ?) would be very useful along with the others so far mentioned. A cubic diskin, and any others in the tablei family would be great as well.

Cubic interpolation is most useful with sample player opcodes like loscil. A better delay tap or vdelay. Other than 2n+1 is needed. If you send the code to me I might try a cubic vdelay or deltap. >Question: is cubic needed? Apparently the difference can be heard, especially on samples. > What about using quadratic interpolation? Cubic seems to be more state of the art. I think there has been some discussion on sinc interpolation as being more efficient than polynomial interpolation although I do not know enough about it to comment.

So here is the updated message: ____________________________________________________________ To Whom it may concern, We are planning the development of a composition environment for soundscapes with the internet as a user interface, tool for distribution, interaction etc. The idea is as follows: a composer links up to the system, which is running somewhere on the internet. the system is presented by a userinterface which helps the composer to do the things she/he likes to do. the system can process sounds, distribute sounds or (parts of) the total soundscape. the system can offer possibilities to communicate with other connected composers etc. The idea originates from a couple of institutes such as: Michael Fahres, NPS-radio 'Supplement" ( http://www.nps.nl/supplement ) and CEM-studio ( http://www.netcetera.nl/cem/). Wolfgang Neuhaus, IMBSE, http://www.worldtune.com/ Andre van Os, NPS internet department ( http://www.omroep.nl/nps/nps/international/ ) Hans Timmermans, Utrecht School of the Arts dep. Muscitechnology ( http://www.hku.nl ) Pieter Suurmond, ( http://www.hku.nl/~pieter ) Niels Gorisse, student Audio-Design at our faculty. Original ideas are: A system to distribute soundscapes to museums, concerthalls, locations in cities, woods, city-parks etc. A system to interact with a number of composers while composing a soundscape in cooperation with them. ... We would like to start a discussion about the relevancy, the specs, wishes of composers etc. with a (limited) group of composers, softwaredesigners etc. If you like to participate in the initial research please comment on this questions: - What would be the benefits of such a system? - What do you expect from such a system? - What do you hate about such a system? - Why use internet?

When I ask for it as a "WAV" file, it can't find it, so something I'm doing is wrong. as soundin in not a macro but an opcode, and the way the code is written the decision about formats happens way below the opcode. ==john Received: from wallace.maths.bath.ac.uk by omphalos.maths.Bath.AC.UK id aa06284; 5 Jan 99 14:46 GMT Received: from [144.173.6.14] (helo=exeter.ac.uk) by wallace.maths.bath.ac.uk with esmtp (Exim 1.92 #2) for jpff@maths.bath.ac.uk id 0zx7KQ-00077b-00; Mon, 4 Jan 1999 10:33:42 +0000 Received: from noether [144.173.8.10] by hermes via SMTP (KAA09127); Mon, 4 Jan 1999 10:32:34 GMT Received: from exeter.ac.uk by maths.ex.ac.uk; Mon, 4 Jan 1999 10:32:20 GMT Received: from exim@droid1.intertrader.com [195.89.138.1] by hermes via ESMTP (KAA02064); Mon, 4 Jan 1999 10:32:20 GMT Received: from budvar.inside.intertrader.com ([10.0.0.6] helo=budvar) by droid1.intertrader.com with smtp (Exim 2.05 #1) id 0zx7F0-0004xB-00 for csound@maths.ex.ac.uk; Mon, 4 Jan 1999 10:28:06 +0000 Message-Id: <3.0.2.32.19990104103311.009b54e0@mail.intertrader.com> X-Sender: andreas@mail.intertrader.com X-Mailer: QUALCOMM Windows Eudora Pro Version 3.0.2 (32) Date: Mon, 04 Jan 1999 10:33:11 +0000 To: csound@maths.ex.ac.uk From: Andreas Schoter Subject: Silence?

This workshop will be in two session of four days at Il Punto di Svolta, a cultural association in Rome (the workshop is for italian-speaking peop= le=20 because the language will be italian). ********************************** Usare DirectCsound in tempo reale workshop tenuto da Gabriel Maldonado autore di DirectCsound =20 presso: IL PUNTO DI SVOLTA - FEBBRAIO e APRILE 1999=20 Usare DirectCsound in tempo reale. --------------------------------- Csound =E8 diventato il linguaggio di sintesi sonora pi=F9 diffuso nel mo= ndo tra coloro che operano nel campo della Computer Music: per migliaia di persone =E8 diventato lo strumento principale per la produzione di musica elettronica. I motivi di questo successo e diffusione si trovano nel fatto che Csound gira praticamente su tutte le piattaforme e su tutti i principali sistemi operativi oggi disponibili; inoltre ha al suo attivo decine di persone sparse nel mondo che si occupano costantemente del suo aggiornamento e dell'espansione delle sue possibilit=E0. Si tratta quindi= di uno strumento vivo ed in continua evoluzione. Una caratteristica molto importante, introdotta di recente in questo linguaggio per le piattaforme Wintel, =E8 la possibilit=E0 di funzionare = in tempo reale e di modificare i parametri di sintesi via MIDI dal vivo. Oggi, con un computer relativamente economico, =E8 possibile fare meglio = ci=F2 che fino a poco tempo fa era possibile solo su piattaforme del costo di centinaia di migliaia di dollari. Questo apre nuove strade e nuovi paradigmi creativi ai compositori di oggi. L'oggetto di questo workshop sar=E0 il programma DirectCsound, una versio= ne potenziata di Csound che permette l'uso del tempo reale, del MIDI IN e de= l MIDI OUT, nonch=E9 la novit=E0 esclusiva dell'estensione del linguaggio mediante le subroutines. Tale versione =E8 stata recentemente oggetto di analisi da parte di parecchi utenti a livello mondiale.Tali utenti ne han= no testato le prestazioni comparandola con altre versioni; =E8 quindi stata compilata una tabella in cui la versione di Maldonado =E8 risultata la pi= =F9 veloce per la relativa fascia di computer. Inoltre questa versione supporta i driver DirectX che consentono un netto miglioramento del=20 problema della latenza. Gli opcodes introdotti da Maldonado saranno in breve disponibili anche nella versione standard di Csound e saranno quindi implementati in tutte = le altre piattaforme hardware. Il workshop Il workshop si rivolge a persone che hanno gi=E0 una conoscenza di base d= el linguaggio Csound e si pone come scopo quello di fornire ai partecipanti = la possibilit=E0 di comporre interattivamente musica non realizzabile con me= zzi tradizionali e assisterli in una produzione sperimentale. Uno dei principali ostacoli alla diffusione di Csound =E8 la sua difficol= t=E0 iniziale, essendo privo di un'interfaccia grafica. Nel workshop si affronteranno quindi tutti gli eventuali problemi che gli utenti possono incontrare con l'uso in tempo reale, dalle opzioni di avvio alla stesura = di orchestre e partiture orientate ad un'esecuzione dal vivo, con l'analisi dei nuovi opcodes dedicati e il loro uso in contesto musicale. Il workshop affronter=E0 i seguenti argomenti: - Messa a punto di DirectCsound e del front-end VMCI - Capire i parametri di inizializzazione e parametri continui. - Strumenti dell'orchestra: parametri generati internamente e parametri ricevuti dall'esterno. - Orchestre SA e MA: loro uso nella composizione interattiva e nelle performance live. - Opcodes orientati al controllo in tempo reale: famiglie ctrlXX, midicXX= , sliderXX. Estensione della durata delle note. - Opcodes orientati al MIDI OUT - Opcodes orientati al processamento dei segnali MIDI. Funzione trigger. - Teoria e applicazione dei microintervalli. Elementi di calcolo di scale temperate e scale naturali. Opcode cpstmid. - Chiamata subroutine (opcodes Xcall, Xargc e Xargt). - Uso delle orchestre SA in tempo reale. - Uso della modalit=E0 'one-key-play'. - Uso dei nuovi generatori di funzioni. - Uso dei modelli fisici waveguide in tempo reale. Il workshop consister=E0 di 32 ore distribuite in due sessioni di 4 giorn= i ciascuna; alcune ore di trattazione teorica ed alcune di laboratorio durante il quale ogni partecipante sar=E0 seguito personalmente. La prima sessione sar=E0 nel mese di FEBBRAIO a partire da meta' mese,=20 la seconda nel mese di APRILE. il mese di pausa servir=E0 ai partecipanti per riflettere sulle nozioni apprese durante la prima sessione, rivedendole e perfezionandole in un secondo tempo, durante la seconda sessione. I partecipanti potranno essere effettivi e uditori. Il numero di partecipanti effettivi =E8 limitato a 12 persone; gli uditori potranno assistere al seminario, ma non effettuare le prove sui computer. A tutti i partecipanti effettivi verr=E0 consegnato un attestato di partecipazione e potranno avere, su richiesta, una copia dell'ultima versione dei software DirectCsound e VMCI (Virtual Midi Control Interface).

This version is synchronized with canonical Csound 3.494 (all opcodes, macros, score math, etc.) 2. unified orc/sco files are now enabled (with a little modification with respect of that of canonical version). These files can contain the execution flags too. To run an unified file simply drag it to the csound.exe file icon (the file msut have .csd extension). These files use the M.Gogins syntax: see test.csd as an example. 3. New opcodes: "fout", "vincr", "clear" and "fold" 4. Midi Program Change messages and Pitch Bend are now implemented in realtime. 5. Operator "^" allows power raising in score macro arithmetic. 6. Many bugs fixed. 7.

Adjusting an opcode is not trivial, and certainly is Oversampling waveform tables in order to avoid the birdies is less a problem, than oversampling sound files, which runs into the problem of having the storage space for the sound and the access to SR conversion routines. I think hifi interpolation is most needed in any opcodes which pitch shift sound files, particularly if the shifting is dynamic as in these cases the foldover becomes most apparent. (I have actually resorted to 2X and 4X oversampling sound files with adjusted indexing to avoid this problem, a total kludge.) Hifi interpolation opcodes will most definitely be useful in these cases. Towards this (my vote), I think a cubic interpolating tablei (tablei3 ?) would be very useful along with the others so far mentioned. A cubic diskin, and any others in the tablei family would be great as well.

Yes. or maybe an option or maybe two opcodes - one for power-of-2(+1) and one for arbitrary length. Slower is OK with me, since I don't usually work in real time. Others may disagree, however.

Opcodes that read short "simple" waveforms are probably best left alone (but it doesn't hurt to have variants which use higher order interpolation, of course), because typically these waveforms can be stored at whatever sample rate is desired, within reason. That is, they can be oversampled a lot, without using up a lot of memory. The oversampling reduces the interpolation noise. Wavetable synthesis typically deals with much longer waveforms, and thus it is usually not feasible to oversample. It is great that higher order interpolation is/has been implemented! Greg.

I've just recently downloaded DirectSound 2.5 by Gabriel Maldonado. I really like the .csd file for everything. I've found some things that are a little weird, though. When using soundin or loscil, the full path name is needed when working in a .csd file. I don't know if this is unique to DS 2.5 or if it's true for all compilations that use .csd. Another thing is that the midifile flag (-F filename.mid), although it works fine when used with orc and sco, returns the following error message when running a csd file: Cannot Open " (quotation mark). I just wanted to see if anybody had any insight. Other than those two minor details, I'm very happy with this new version. The .csd idea is a godsend, as it makes my desktop look a lot cleaner when running these things! Thanks again to Gabriel Maldonado!
