METAMORPHOSIS

Found in Translation

PRISM translates a single audio recording into many forms. Users and VAWs can request specific representations of a recording, as either rendered data (e.g. audio or MIDI track) or the tools to create one (e.g. virtual instrument or ambience profile).

Original Performance

The PRISM workflow begins with raw audio files from a recorded performance. PRISM is designed to handle any type of audio file (e.g. monophonic mixes or individual tracks) at any audio quality. (In practice, results vary.) The Engine runs as either a stand-alone application, or from inside standard DAW plugin as an offline process.

Source Audio
Black and white image of an audio waveform.
Analysis

Deconstructs audio streams into a database of PRISM Audio Atomic Data. These PRISM contain low-level components. Each set represents the data as a different type of building block.

Low-level Data
Computer graphics representation of atoms.
Modeling

AAD (Audio Atomic Data) is assembled into different types of pre-existing Prototypes. Each Prototype contains algorithms to create mathematical models specific to a performance. The models represent static data, and are tagged by higher-level metadata. Common examples include instruments, articulations, and notes.

High-level Data
Word cloud of PRISM metadata.
Transcription

Once the models are complete, PRISM analyses them to build semantic representations of the performance. This process is informed by grammatical and semantic (e.g. Schenkerian) analysis, and builds hierarchical structures. This data can then be flattened to create temporal events lists such as MIDI files.

Synthesis

The PRISM Synthesiser renders PRISM models in real-time, as a standard MIDI virtual instrument. It can recreate the original performance, with the original sounds and ambience. It also supports continuous modification of many types of sonic, musical and physical parameters.

Virtual Instruments
Three modules from the PRISM plugin.
Rendering

The output of the PRISM's virtual instrument may then be rendered to standard audio files within a DAW. They can contain PRISM-specific RIFF metadata, read by the PRISM Effect Processor (i.e., VST, AU, AU) for enhanced DSP.
