Method for spatializing a sound stream including a sound object in a motor vehicle

Abstract

A method for spatializing a sound stream including a sound object in a motor vehicle comprises the steps of: extracting (203) the voice using an artificial intelligence model to separate the sound stream into two tracks, a first track including the sound object and a second track including the other sound elements of the sound stream; spatializing (205) the first track so that the sound object is perceived by a user of the motor vehicle as originating from a predefined location in the vehicle; and simultaneously broadcasting (209) the first and second tracks in the vehicle. A spatialization device and a motor vehicle including the device are also described. Figure to be published with the abbreviation: Fig 2

Claims

Demands

1. A method for spatializing a sound stream including a sound object in a motor vehicle comprising the steps of: • extracting (203) the sound object by using an artificial intelligence model so as to separate the sound stream into two tracks, a first track including the sound object and a second track including the other sound elements of the sound stream; • spatializing (205) the first track so that the sound object is perceived by a user of the motor vehicle as coming from a predefined location in the vehicle; • simultaneous broadcasting (209) of the first and second tracks in the vehicle.

2. A method according to claim 1, wherein the sound stream being formed by a musical stream, the second track is separated into as many sub-tracks as there are instruments or groups of instruments.

3. A method according to claim 2, wherein each subtrack is spatialized to appear as originating from a predefined location of the vehicle.

4. Method according to claim 1, 2 or 3, wherein the user is in the driver's seat of the vehicle.

5. A method according to claim 1, 2, 3 or 4, wherein the artificial intelligence model is a trained neural network.

6. A method according to any one of the preceding claims, wherein the sound object is a voice.

7. Method according to claim 6, wherein the predefined location of the voice is in front of the user.

8. Device (103) comprising a memory associated with at least one processor configured to implement the method according to one of the preceding claims.

9. Motor vehicle (101) comprising the device according to the preceding claim.

10. Computer program product comprising program code instructions which, when the program is executed by the device according to claim 8, cause the device to implement the method according to any one of claims 1 to 7. [Fig. 1]
