Version 5.0 Release

Changes

• Added new room to the dataset: R32 - ASH Listening room, a virtual listening room containing elevation angles from -60 degrees to +60 degrees.
• Added E-APO configurations for room R32.
• Added over 100 new HpCFs for a range of around-ear, on-ear, and in-ear headphones a3ebb68
• Modified naming convention of HpCFs. Alternative field has been renamed for applicable headphones. "_A" renamed to "__Sample_A", "_B" renamed to "__Sample_B", etc. "__Avg" renamed to "__Average".

Version 4.0 Release

Changes

• Added over 200 new HpCFs for a range of over-ear and in-ear headphones 7ac3677
• Minor optimisations made to BRIR low frequency equalisation resulting in smoother low frequency responses for most rooms in the dataset.
• Minor optimisations made to pinna compensation to improve compatibility of BRIRs with over-ear and on-ear headphones. In-Ear_Headphones Compatibility filter updated accordingly
• Minor optimisations made to the Improved Diffuse-Field EQ filter
• Reduced FIR length of Diffuse-field_Target_to_Harman_Target and Room_Target_Inverse filters from 8192 to 4096

Version 3.1 Release

Changes

• Added new filter: Additional_Filters\Low_Frequency_Roll-off_Compensation a generalised equalisation filter can be used to apply low frequency gain and compensate low frequency roll-off that is typically present below 100Hz in many headphones.
• Added 2 HpCF plots (Sony_INZONE_H9 & Sony_MDR_Z7_D) that were previously missing from the dataset.

Version 3.0 Release

Changes

• Added new room to the dataset: R31 Small Room J.
• Added over 210 new HpCFs to the dataset. 4367e76 9078ef4
• Added BRIRs in True stereo WAV format (LL LR RL RR) for each room in the dataset.
• Minor optimisations made to low frequency BRIR integration for most rooms in the dataset.

Version 2.1 Release

Changes

• Slight reductions in reverberation made to most rooms in the dataset. List of modified BRIRs: 8acd688

Version 2.0 Release

Changes

• Added a set of BRIRs in HeSuVi WAV format (44.1kHz and 48kHz) for each room in the dataset.
• Added new position to Room 30 (Laboratory Position 2).
• Fixed a synchronisation issue in rooms R09 (Adream Laboratory) and R10 (Room Auditorium 3) that was causing a range of azimuths to have additional delays.
• Updated 5.1 E-APO configurations: zeroed out SL and SR channels to prevent side channel bypass
• Reordered E-APO configurations
• Minor optimisations to low frequency BRIR integration for rooms R15 (Room HU201), R17 (Coupled Rooms), R25 (Small Room E), R26 (Studio), & R28 (Small Room F)

Version 1.0 Release

Features:

• A set of 30 rooms suitable for everyday listening
• A set of Equalizer APO configurations for multiple speaker configurations in each room.
• An updated set of HpCFs, now totalling 3,393. Over 2000 new HpCFs added since the V8.0.0 release of the ASH-IR-Dataset
