1. A method of generating a Personalized Audio Content (PAC) comprising,selecting Audio Content (AC) to personalize;
- selecting an Earprint;
generating a PAC using the Earprint to modify the AC; and
checking the AC to see if at least one portion of the AC is suitable for personalization before the step of generating a PAC, and if the at least one portion of AC is not suitable for personalization then the step of generating a PAC is not enacted and a message stating that the at least one portion of the AC is not suitable for personalization is generated instead, wherein the step of checking suitability includes at least one of;
checking to see if the minimum amplitude of the AC is above an amplitude threshold value;
checking to see if the data bit-rate of the AC is above a bit-rate threshold value;
checking to see if the dynamic range of the AC is above a dynamic-range threshold value;
checking to see if the frequency bandwidth of the AC is above a frequency bandwidth threshold value;
checking to see if the total time-duration of the AC is above a time-duration threshold value;
checking to see if the spectral centroid of the AC is within a predetermined absolute difference from a spectral centroid threshold value; and
checking to see if the interchannel cross-correlation between predetermined AC channels is within a predetermined absolute difference from a cross-correlation threshold value, wherein the Earprint includes at least one of;
a Head Related Transfer Function (HRTF);
an Inverse-Ear Canal Transfer Function (ECTF);
an Inverse Hearing Sensitivity Transfer Function (HSTF);
an Instrument Related Transfer Function (IRTF);
a Developer Selected Transfer Function (DSTF); and
Timbre preference information.
