Abstract: Instructions stored in a tangible, non-transitory, computer-readable medium executable by a computing device to record audio. The instructions include instructions to, when a first record command to record a first piece of audio is detected, generate an original audio composition, which includes a first audio file reference to a first audio file that stores a digital representation of the first piece of audio, a first waveform file reference to a first waveform file that stores a digital representation of intensity of the first piece of audio, and a first metadata. Additionally, the instructions includes instructions to, when a second record command that modifies at least a portion of the first piece of audio is detected, generate an audio fragment, which includes a second audio file reference to a second audio file that stores a digital representation of the second piece of audio, a second waveform file reference to a second waveform file that stores a digital representation of intensity of the second piece of audio, and a second metadata. More specifically, the first metadata and second metadata describe playback organization of the first audio file, the second audio file, the first waveform file, and the second waveform file, and enable recomposition of the original audio composition and the audio fragment into a composed audio composition.
