Mobile gaming has evolved significantly in recent years. It has gone from simple 8-bit games like Snake on the Nokia 3310 to complex mobile game titles that can rival some of the best console games. During that evolution, sound has played an important role in the growth of mobile games. Early games provided basic tones and functional cues, while modern games offer immersive soundscapes that at times feel cinematic. As smartphone technology developed and sound hardware advanced, sound has become an important component of mobile games that determines quality and player engagement.
Why Evolution Was Required
Technological innovation changed how mobile devices are used. What was once a simple communication device used to make phone calls and send messages has now become an all-around entertainment device. Modern smartphones can connect to the internet, stream music and videos, and play console-like games. As the modern mobile game market grew, so did players' demand for more realistic and immersive soundscapes.
Mobile racing games needed real car sounds. Mobile first-person shooter games need to emulate the sounds of real gunfire, and mobile casino games need to sound like real casinos. Online players who play on mobile want their game’s sounds to be as immersive and engaging as the games themselves. These online casino games keep players entertained through expansive game libraries, timely payouts, and bright graphics that emulate the look and feel of a casino floor. So, the sound design of these games must match this premium look and feel.
Modern Game Soundscapes Versus Old Game Soundscapes
Early mobile game sounds were limited by very basic hardware. Pre-smartphone handsets had monophonic speakers that could only play a series of beeps and tones. Game developers working on those platforms had to therefore use basic tones and MIDI-like melodies in creative and functional ways. Beeps were used to notify players of actions, taps were used to indicate character motion, and melodies were used as ambient sound.
Modern smartphone-era games are very different. Firstly, modern mobile games benefit from advanced hardware and software upgrades in comparison to earlier games. Smartphones can play more complex sound files, support stereo output, and play high-sampling-rate audio. These functionalities allow developers to create expansive soundscapes that include realistic sound and intricate music. Mobile games in the smartphone era include layered soundscapes that create immersive game environments. Smartphone hardware capabilities are increasing every year, which means mobile game developers can create bigger games with more complex sound files.
The Rise of Dynamic and Interactive Soundscapes
An important shift in mobile sound design came with the adoption of game engines such as Unity and Unreal. The availability of these game engines made it possible for mobile developers to create their games using dynamic and adaptive audio systems. Benefits of this include audio that changes according to the game’s environment or needs. Factors such as player behavior, environmental triggers, or in-game events can trigger a sound or music change.
An example of this is how racing games have engine sounds that increase as the player gains speed. This demonstrates dynamic sound at work. Another feature made possible by new game engines is layered sound. Role-playing games are typical examples of layered sounds, and music is used to create or shift the ambience or mood of a game. This is especially used to create different atmospheres for different sections of the game.
Using Voice and Foley to Create Cinematic Audio
As mobile game technology grew, mobile games started to feature soundscapes that could, at one time, only be found in high-budget console games. Voice acting, foley sound effects, and fully orchestrated soundtracks. These audio elements ensure that mobile games do not feel lifeless and give them a cinematic feel. This is a strong contrast to earlier digital mobile games that included basic polyphonic tunes playing over character text boxes to convey dialogue. Modern game audio is used to elevate storytelling, creating a truly immersive mobile gaming experience.
