  • Many small fixes

0.11.0

  • Switch to setuptools for building

  • Improve testing framework

  • Better management of optional parameters in some functions

  • 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

  • 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
