Abstract
Various arrangements for reducing auditory spatial aliasing for a user are detailed herein. A first delay filter may be set that delays output of a first audio signal by a first duration to a speaker of a device compared to a second speaker. A second delay filter may also be set that delays output of a second audio signal by a second duration. The first and second audio signals can be output by the speakers.
Claims20
A system for reducing auditory spatial aliasing, the system comprising:
- a first stereo channel comprising a first delay filter that delays output of a first audio signal by a first duration to a first speaker of the first stereo channel;
- a second stereo channel comprising a second delay filter that delays output of a second audio signal by a second duration to a second speaker of the second stereo channel;
- and
- an anti-aliasing profile datastore, wherein the anti-aliasing profile datastore stores a plurality of anti-aliasing profiles used to define the first duration and the second duration based on a state of the system.
1 more element
A method for reducing auditory spatial aliasing of a device, the method comprising:
- selecting an anti-aliasing profile from a plurality of anti-aliasing profiles, wherein
- each anti-aliasing profile of the plurality of anti-aliasing profiles reduces 4 auditory spatial aliasing by adjusting audio delay based on a state of the device;
- setting a first delay filter that delays output of a first audio signal by a first 6 duration for a first stereo channel based on the anti-aliasing profile;
- setting a second delay filter that delays output of a second audio signal by a second duration for a second stereo channel based on the anti-aliasing profile;
- and
- outputting the first audio signal using the first stereo channel and the second audio signal using the second stereo channel.
