v0.10.1

v0.10.1 - 2026-05 -01

Added

• Added a boolean flag plot_walls to toggle wall rendering in Room.plot.
• Set the plot_walls to False for AnechoicRoom by default.

Changed

• Removed the deprecated absorption parameter from ShoeBox,
  Room.from_corners, and Room.extrude.
• Modernized the build system to use pyproject.toml and CMake.
• External dependencies (Eigen, nanoflann, pybind11) are now
  automatically managed via CMake's FetchContent.
• Switched to dynamic versioning using setuptools_scm.
• Relocated the test suite from the source package to a top-level tests/ directory.
• Update the continuous integration to use cibuildwheel to handle all platforms
  including manylinux.
• The location of the SOFA files can be specified by the
  PYROOMACOUSTICS_DATA_PATH environment variable.

Bugfix

• Fixes NaNs that may appear in RT histogram in some cases (issue #433). Thanks @jguice.

v0.10.0 - 2026-04-01

Ray Tracing Directivity

This new release introduces source and receiver directivities for the ray
tracing simulation engine.

• Support for source directivities in non-shoebox rooms using the images source
  model.

• New pyroomacoustics.random module that provides some primitives for
  sampling at random from arbitrary distributions on the sphere. This is used
  for source directivities in the ray tracing simulator.

• New octave filter bank with energy conservation and perfect reconstruction
  described in Antoni, "Orthogonal-like fractional-octave-band filters," 2009.
  The filter bank is implemented in
  pyroomacoustics.acoustics.AntoniOctaveFilterBank.

• A method sample_rays is added to the Directivity objects to provide a
  unified interface to sample rays of sources used for ray tracing.

• The class directivities.SphericalHistogram allows to collect and display
  histograms on the sphere which can be useful to visualize and test
  directivities.

Added

• A new random sub-module that contains a Numpy random number generator to use
  package wide and some methods to set the seeds for this generator and that of
  the libroom module.

• New methods to sample from spherical distributions either analytically, or by
  rejection sampling are provided in random.

Changed

• Bumped the numpy requirement to v1.17.0 to use the numpy.random.Generator objects.

• Adds random "bending" of the rays to account for scattering in the ray tracing.

• Refactor the way the RIR is weighted with the histogram in simulation/rt.py.

• Improves pra.experimental.measure_rt60: Compute the T60 using a fit. Default is
  log-domain. Adds option to fit in linear domain.

• Add Directivity pattern for real spherical harmonics.

• Flip the settings to use octave_bands_keep_dc=True by default. There should be
  minimal change due to the introduction of the high-pass filter in v0.9.0.

Bugfix

• Fixes the lowest octave band filter that was malformed when using
  octave_bands_keep_dc=True.

• Fixes the computation of the octave band widths that were not correct for the lowest
  and high bands.

• In doa.py, the ax.xaxis.grid and ax.yaxis.grid parameters were changed from b to visible.

• Fixes MicrophoneArray.append(MicrophoneArray) AttributeError: 'MicrophoneArray' object has no attribute 'shape'.

• Fixes issue #421: When generating a highpass filtered room impulse response make
  sure that the output is a memory contiguous NumPy array.
