Version 8.0.0

Notable Changes

• Updated the equalisation of most BRIRs in the dataset. A new room target curve has been applied with reduced treble roll-off. Inverse filter 'Room_Target_Inverse' has been updated accordingly for removal of the (updated) room target curve if required.
• Added a set of reduced reverberation BRIRs for room R11_P2 (Small_Broadcast_Studio_Pos_2_400ms).
• Latest low frequency BRIRs were integrated into rooms R07_P1, R07_P2 (Conference_Room) & R35 (Small_Room_E) resulting in reduced low frequency reverberation. Resulting low frequency response is now more consistent with similar sized rooms.
• Updated R05B_400ms BRIRs: modified source speaker position for a selection of azimuths (-25 deg to -90 deg) resulting in an improved and more symmetrical stereo image.
• Updated E-APO configurations.

Version 7.2.0

Notable Changes

• Added a set of alternative BRIRs for room R22_P2 (Large_Room_Pos_2) with reduced reverberation (RT60 = 400ms).
• Added filter HpCFs\Additional_Filters\Room_Target_Inverse.wav which can be used to remove the smooth downward slope that was applied to the rooms.
• Updated most BRIRs with improvements to low frequency equalisation and reductions in low frequency reverberation.
• Added additional azimuths (-35,-40,35,40 degrees) for rooms R05B, R06P2 and R07.
• Replaced the room R17 (Room_HU201) BRIRs with their reduced reverberation alternative BRIRs, leaving a single set of BRIRs for R17.
• Updated E-APO configs.

Version 7.1.0

Notable Changes

• Added a set of alternative BRIRs with reduced reverberation time (400ms) for room R20 (Seminar Room RWTH Aachen), position 1.
• Updated E-APO configurations.
• Updated the equalisation of all BRIRs with improved pinna compensation for circumaural headphones. Compatibility filters for on ear headphones and in ear headphones have been updated. The resulting equalisation for on ear and in ear headphones remains unchanged.
