Disclosed are systems, methods and devices for improving audio processing and playing multiple sounds using fewer resources. Various implementations may create audio files, in some cases from a single sample of a type of sound, where the files represent specific quantities of that type of sound, such as 10 footsteps or 1000 claps. Given a desired target number of sounds to play, various implementations determine an appropriate combination of the employable audio files to represent the desired number of sounds, and play or render the combination as an approximation of the desired target number of sounds. By using single audio files that represent and sound like multiple instances of a specified type of sound, the various implementations use significantly fewer computing and audio resources than playing an equivalent number of audio files each of which contains a single instance of the specified type of sound.
