In contrast, the present implementation is signal-dependent. While various methods have been proposed to remedy timbral artifacts or to enhance the spatial resolution, the effectiveness of signal-independent rendering methods appears to be limited for lower-order input signals. For lower-order input signals, especially first order, the resulting binaural output signal suffers from poor resolution and externalization, and, most notably, a severe roll-off towards higher frequencies. Technical Detailsīinaural rendering can be achieved via Ambisonic decoding for an array of virtual loudspeakers and subsequent convolution with the respective HRTF, or, in case of the more recent least-squares methods, direct rendering via multiplication with a decoder matrix ( BinauralDecoder). However, we advice you to use the highest possible accuracy setting. In most cases, the default values will be just fine. computational cost) and the FFT size (frequency resolution vs.
The controls in the ‘Settings’ section allow to set the accuracy (reproduction quality vs. After generating a preset, you might need to reload the directory before new files appear. Preset files in the current directory are now displayed in the above combo box. To load a preset, first navigate to the preset directory (the directory containing the HRTF) using the ‘Select Folder’ button. There’s also a preprocessed SOFA file available here: HRIR_5. In case you don’t have a personalized HRTF set, you can also use SOFA files from artifical head measurements, e.g. Use the ‘Create Preset’ button to select and process an HRTF in SOFA format. The plug-in requires to load a preset file which was previously generated from the HRTF to be used.

Feel free to share your experiences with us, especially if you encounter any problems. Since this is a beta version, any feedback is highly appreciated. However, we recommend using high-resolution artificial head HRTFs. The plug-in allows the use of custom HRTFs in the SOFA format. It is based on a recently proposed parametric extension of the constrained least-squares decoder, where both direct sound impinging from the most prominent source direction and diffuse sound are reproduced exactly. The AdaptiveBinauralDecoder is a super-resolution binaural rendering plug-in for 1st-order Ambisonics.
