• Fix crashes due to incorrect management of parameters in deprecated functions

0.12.0.0

• Switch to new version numbering scheme also in view of PEP 440

• Many small fixes

0.11.0

• Switch to setuptools for building
• Improve testing framework
• Better management of optional parameters in some functions
• API cleanups (a best effort has been put in retaining back-compatibility. Some back compatibility functions are deprecated and will be removed)
• Code style improvements

0.10.1

• Fix setup script for compatibility with MacOs
• Provide getting started guide for MacOs
• Minor fixes in documentation

0.10.0

• Ready setup script for distribution
• Implement partitionABCD in delsig module
• Make delsig module PEP8 compliant
• Some minor improvements to utility functions

0.9.1

• Apply some fixes to the modulator simulator
• Make building for 64 bit windows possible
• Implement clans NTF design method
• Implement minmax NTF design method (only single band LP, so far)

0.9.0

• Include a local version of the discontinued cvxpy package by Tomas Tinoco de Ribera. This is a temporary measure

0.8.3

• Fix a typo in the fast DSM simulator (only affecting case where modulator structure is passed in ABCD form)
• Add example from ICECS 2013 paper
• Enhance quantization_weighted_noise_gain function

0.8.2

• Fix some licensing issues

0.8.1

• Prevent synthesizeNTF failure if there are no zeros to optimize
• Improve some docstrings
• Remove some spurious imports
• Fix normalization in quantization_noise_gain functions

0.8.0

• Add NTF design method based on a noise weighting function
• Provide a new module with standard audio weighting functions
• Provide a new module with ISO 226 equal loudness contours
• Provide a new module with NTF design methods for psychoacoustically optimal modulators for audio signals
• Fix a regression in ds_optzeros introduced with version 0.7.3 and preventing some example code from running
• Add new examples from a recently published TCAS-II paper
• Use 'ba' specifier for requiring filters in numerator/denominator form
• Make evalTF function more robust against complex overflow
• Bug fixes

0.7.3

• Apply fixes introduced in DELSIG 7.4
• Make port of DELSIG functions more consistent with DELSIG
• Provide better documentation to some functions
• Bug fixes

0.7.2

• Make codebase compatible with scipy 0.12.0
• Make delsig module contain its reference delsig version
• Minor fixes to the documentation

0.7.1

• Fix computation of impulse response of filters that are already in FIR form.
• Avoid direct access to numpy array data in Cython code. This is in preparation for future releases of numpy where direct access to array data is already deprecated.
• Implement the synthesizeChebyshevNTF NTF design strategy from DELSIG.

0.7.0

• Dropped dependency on ATLAS on Windows. Now using the blas functions made available via scipy. The linux version still uses ATLAS that has a little performance advantage.
• Much simpler installation on Windows
• API changes: renamed synthezize_ntf_from_filter_ir into synthezize_ntf_from_filter_imp; swapped param order in q0_from_filter_imp_response.
• Fixed passing of options to synthesize_ntf_from_q0 and synthesize_ntf_from_filter_imp

0.6.1

• Add project logo to the project source
• Ship html documentation separately from main code
• Add sample code to replicate the results in an ICECS 2012 paper

0.6.0

First released version
