Now, all music files that you play are filtered by myHRTF Personalized Filters. You my change the filters at any time by re-configuring the Stereo Convolver as described above.
Sampling rate
For best performance, the sampling rate of myHRTF Personalized Filters should match the sampling rate of the file being played. For this purpose, myHRTF Personalized Filters come in all standard sampling rates. Matching sampling rates can be ensured by loading filters with the same sampling rate as the music file manually, but this process may be tiresome in case the sampling rates change often. Alternatively, a resampler DSP component may be added to the Active DSPs BEFORE the Stereo Convolver as shown below. In this case, it is recommended to configure the resampler to 96.000 Hz by clicking "..." and to configure matching myHRTF Personalized Filters in the Stereo Convolver. High-quality resamplers such as the dBpoweramp/SSRC DSP component are considered audibly transparent.
