Activision wants an AI to customize the soundtrack in a multiplayer depending on the development of the game

Oct. 18 (Portaltic/EP) –

Activision is working on a new artificial intelligence (AI) soundtrack creation system for games like Call of Duty, which would allow music to be adjusted to the game circumstances and the moods of the game’s characters.

This technology is called ‘Systems and methods for generating and dynamically modulate music based on game events, player profiles and/or player reactions’, and is included in a patent granted to the company, filed on April 25 and which has now been made public in October.

In The document, Activision recognizes the possibilities of customization of existing avatars and suggests that this does not happen in the music of video games, which do not contemplate dynamic changes based on the development of the games.

The developer comments that some titles do allow the replacement of the soundtrack, but that the possibility of replacing it has not yet been extended. modify specific musical elements and adapt them to the circumstances.

To create a soundtrack that fits what is happening at each moment of the game and the characters that star in it, Activision has patented a system based on AI technology that develop personalized and unique music for games with multiplayer like Call of Duty.

This writing indicates that it is a format that generates music by identifying a mood based on one or more profiles of the events that take place in the game and that modulates the musical elements based on the mood of the title characters, your movements or their answers during the action of the game.

Thus, the Activision patent describes different methods for generating dynamic music. In the first place, it proposes to analyze profiles with different states of mind through models of machine learning (‘machine learning’) in multiplayer games.

In turn, the developer proposes to take into account elements of music such as beat, meter, tempo, rhythm, melody, harmony, progression, tone, timbre, sound texture or spatial location; in order to create an audio segment depending on the mood.

For the creation of this personalized soundtrack, the level of skill or experience of the players will also be taken into account, be it beginner, enthusiast or intermediate or expert level; as well as the player’s degree of commitment to the video game and the achievement of their goals (also low, medium or high).

Based on this diversity of options, Activision plans to develop a system that adjusts to the personal circumstances of each user, with the aim of creating an experience fully personalized and immersive.

To exemplify the operation of this solution, the company talks about how the background music would work during a confrontation with an enemyWhether you were a professional player or a beginner.

In the first case, once the music generation module receives information indicating that the player is defeating the opponent, the system will dynamically modulate the music “to make the experience more intense and engaging.”

On the other hand, if you are a beginner player who has difficulty understanding how to finish the enemy and has suffered several defeats, the custom soundtrack generation system change the intensity of the music to make the experience less traumatic or frustrating. It also includes sounds and audible signals to warn the player when to attack his opponent or when to dodge an attack.

It should be noted that, although the patent indicates that this AI-based solution that uses ‘machine learning’ systems is mainly focused on to multiplayer mode, clarifies that it can also be applied single player and games that do not need Internet.
