1. A tablet system for reducing auditory spatial aliasing, the tablet system comprising:
a tablet computer comprising a first plurality of magnets;
a dock that removably attaches with the tablet computer using a second plurality of magnets that magnetically couple with the first plurality of magnets, wherein the tablet computer comprises:
a first set of multiple speakers in communication with a first audio source, wherein the first audio source outputs a same first audio signal to each speaker of the first set of multiple speakers;
a second set of multiple speakers in communication with a second audio source, wherein the second audio source outputs a same second audio signal to each speaker of the second set of multiple speakers;
the first audio source, comprising a first delay filter that delays output of the first same audio signal by a first duration to a speaker of the first set of multiple speakers compared to a second speaker of the first set of multiple speakers; and
the second audio source, comprising a second delay filter that delays output of the second same audio signal by a second duration to a speaker of the second set of multiple speakers compared to a second speaker of the second set of multiple speakers.
