Simple morphing demo updated for Loris 1.5.3

A simple demonstration of sound morphing using the Loris Python module is available in the loris-demo package on the Loris downloads page at SourceForge. This (old) demonstration script has been updated for Loris 1.5.3.

Loris is an Open Source C++ class library implementing analysis, manipulation, and synthesis of digitized sounds using the Reassigned Bandwidth-Enhanced Additive Sound Model, developed by Kelly Fitz and Lippold Haken at the CERL Sound Group. For more information about Loris and the Reassigned Bandwidth-Enhanced Additive Sound Model, please visit... read more

Loris 1.5.3 released

Loris 1.5.3 is a minor upgrade to Loris 1.5.2, offering enhancements
to the Analyzer class and improved fundamental frequency estimation
capabilities.

64-bit compatibility has been improved (BIG thanks to Bruce McCosar
for 64-bit assistance and testing), and Visual Studio (2008) projects
are provided for building the Loris Python module under windows.

Some of the changes in Loris 1.5.3 are incompatible with older Loris
versions, and may require changes to existing program code.... read more

Loris 1.5.2 released

Loris 1.5.2 is a minor upgrade to Loris 1.5.1, providing support for dense resampling of Loris partials in the Python interface. Densely-resampled data can be exported to SDIF files to be used with the CNMAT sinusoids~ external for bandwidth-enhanced additive synthesis in Max/MSP.

Loris 1.3 released

Loris 1.3 has been released.

This is Loris 1.3. Loris 1.3 offers significant bug fixes and new features, relative to Loris 1.2, and is recommended for all Loris users.

Loris library compatibility issues

Loris does not (yet) work with FFTW version 3, nor does it work with versions of the IRCAM SDIF library newer than 3.7.1 The next release of Loris will be compatible with FFTW3, and will have no dependency on the IRCAM SDIF library. Meanwhile, please install version 2 of the FFTW library and any version of the IRCAM SDIF library earlier than (but not including) 3.8.

Loris CVS tree has been modified

The CVS tree for the Loris project at SourceForge has been modified. If you are using CVS to track Loris development, then you should check out a fresh version of the entire Loris module, and through away your old working directory.

In addition to some structural changes (e.g. all library source is in a single src directory), all C++ source files have had their suffix changed to .C, which should improve compatbility with some compilers and IDEs that did not recognize the .c++ suffix we used to employ.

Loris 1.1 released

Loris 1.1 has been released.

Loris 1.1 is a feature update to Loris 1.0.2.
Loris 1.1 includes more Partial manipulation facilities, an
improved Analyzer with a softer amplitude threshold and
frequency contour tracking, and a Resampler for sampling
a collection of Partials at regular intervals, facilitating
data exchange with systems supporting more traditional
short-time analysis methods. Loris 1.1 includes improved
auto-configuration and greater compatibility with newer,
more standard-compliant C++ compilers.... read more

Loris 1.0.2 released

This is Loris 1.0.2, a compatibility update to Loris 1.0.1. Loris 1.0.2 includes improved auto-configuration using the GNU autotools and greater compatibility with .NET.

Loris 1.0.1 released

This is Loris 1.0.1, a minor update to Loris 1.0 (and Loris 1.0a). Loris 1.0.1 includes the source for building the Loris Csound module, and fixes many small programming errors that prevented Loris from building with newer, more standard-compliant C++ compilers (such as g++ version 3).

The project files and support for building Loris under old versions of MacOS (pre-X) has also been removed, since it seemed rarely to work and has been very difficult to maintain. See the README document for hints on building Loris under MacOS. A more extensive document will be forthcoming.... read more
