Mouse Head Related Transfer Function processed data

Analyzed head related transfer function (HRTF) of 3 female CBA/CaJ mice. Please refer to an article for how the data are collected.These data may not work for physiology experiment unless the playback speaker setup exactly matches with our setup (including the horns for EC1 speakers). Therefore, the purpose of publishing these data is mainly for exploratory browsing the mouse HRTFs.These files contain HRTFs of 3 mice with a variety of modification of the sound localization cues.allimps variable contains raw HRIR (impulse response) information derived from the raw recordings.Variables with _noitd is ITD-removed version of the impulse responses.Variables with _nospec is spectral-flatted version of the impulse responses.Variables with _ILDequal is ILD-equalized version of the impulse response.Variables with _percep is how the mouse should perceive the sound. This applies a setup-specific filter to mimic the sound structure near the ear drums.Variables with _present is what should be used for stimulation. When this sound is played through speaker, the speaker's own filter makes it closer to _percep version.Variables with _ILDcorrected adjust minor recording condition differences between the left and right ears. This variable should be used to generate the stimuli.To browse the impulse responses.
