This is a major version with the following new features: - Composition. parameter normalisation to 127 (except event time and event duration). Segment graphical editor for drawing and editing Masks and Segment Generator. New composer tool: step sequencer (analog like). - Software synthetizer. New sound generators, filters and effects. More modulation capabilites. - 3D builder tool for creating VRML97 worlds. Scene template providing background world, multi sound spatialisation, - no more use of the Java Media Framework, use an external sound player instead. The GUI has been enhanced, the documentation is online (sorry, not complete, time is lacking a lot). Installation is easy if you are using the Java JDK 1.2 (now Java2). You will discover in the 3D builder that it's possible to control the evolution of graphical objects by using an external MIDI device. This is the first step in building an interactive environment. I hope to provide such capabilities to the sound synthesis in the future, but I certainly need to switch to another runtime environment (maybe java 3d, and AXCsound). As the external MIDI control is not ready for distribution yet ( and anyway is specific to W32 and cosmo player), the program required for this feature is not part of the package. Have fun, as I have fun myself using Csound. jean-pierre lemoine Received: from wallace.maths.bath.ac.uk by omphalos.maths.Bath.AC.UK id aa23062; 7 Apr 99 0:55 BST Received: from [144.173.6.14] (helo=exeter.ac.uk) by wallace.maths.bath.ac.uk with esmtp (Exim 2.12 #1) id 10Ufgh-0001iD-00 for jpff@maths.bath.ac.uk; Wed, 7 Apr 1999 00:55:23 +0100 Received: from noether [144.173.8.10] by hermes via SMTP (AAA14504); Wed, 7 Apr 1999 00:54:16 +0100 (BST) Received: from exeter.ac.uk by maths.ex.ac.uk; Wed, 7 Apr 1999 00:54:08 +0100 Received: from Thuban.AC.HMC.Edu [134.173.53.8] (may be forged) by hermes via ESMTP (AAA17613); Wed, 7 Apr 1999 00:54:06 +0100 (BST) Received: from [134.173.54.6] (Presume06.Rmt.HMC.Edu [134.173.54.6]) by THUBAN.AC.HMC.EDU (PMDF V5.2-32 #36444) with ESMTP id <01J9PXLU0C3O9TKDDX@THUBAN.AC.HMC.EDU> for csound@maths.ex.ac.uk; Tue, 6 Apr 1999 16:54:03 PST Date: Tue, 06 Apr 1999 16:53:05 -0700 From: Erik Spjut Subject: Re: wave file length accurency In-reply-to: <370A5C89.E8DE5351@ibm.net> X-Sender: spjut@thuban.ac.hmc.edu To: Lemoine Jean-Pierre , "csound@maths.ex.ac.uk" Message-id: MIME-version: 1.0 Content-type: text/plain; charset="us-ascii" Sender: owner-csound-outgoing@maths.ex.ac.uk Precedence: bulk Try running it with kr=sr.

Thanks for this explanation, this should be the problem. Unfortunatly, kr=sr doesn't solve the problem i2 19.7834 0.2174 give a file legnth of 20, not 20.0008. In fact, using kr=sr/10 gives a better result (20.006). I think there is no solution in the Csound space. As the deviation is not important, I can build the VRML worl and the synchronisation with the sounds, and then set the length of the sound files with an editor (or maybe using Csound in a second pass).
