LIVENESS AND THE MACHINE Improvisation in Live Audio-Visual Performance
نویسنده
چکیده
Live audio-visual performance is an emerging area of new media arts practice that crosses between, and draws upon, multiple artistic traditions and trajectories. Under a range of nomenclatures – VJing, Live Cinema, Live Media, Expanded Cinema – artists work solo and collaboratively with sounds and images, and significantly, they do this in a performance context. Liveness, then, with its associated notions of improvisation, spontaneity, singularity and ‘the event,’ plays a key role in how live audio-visual performance is understood, valued and marketed. Liveness is a selling point, a mark of difference that separates live performance from the recorded or ‘mediated’, such as music albums, films, television. But how live is live? And, to what degree is the live premised on what is programmed, prepared for, pre-arranged or composed? What assumptions are buried in the celebration of the live, the moment, the real-time? In this paper, with reference to my own practice as a collaborating performer in live audio-visual contexts, I shall discuss the relations between liveness and preparedness in live audio-visual performance.

Examining the Perception of Liveness and Activity in Laptop Music: Listeners' Inference about what the Performer is Doing from the Audio Alone
Audiences of live laptop music have been known to express dismay at the opacity of performer activity and question how “live” such performances actually are. Yet motionless laptop performers endure as a musical spectacle from clubs to concert halls, suggesting that for many this is a non-issue. Understanding these perceptions might help performers better achieve their intentions, inform interfa...
متن کاملDeadmau5, Derek Bailey, and the Laptop Instrument – Improvisation, Composition, and Liveness in Live Coding
Dance music superstar Deadmau5 and the improvising guitarist Derek Bailey represent, through their writing and practice, two very different approaches to performing live. By critically considering the practice of live coding in relation to these divergent approaches, we discuss live coding with regards to where the liveness lies and how the laptop and soware are treated as a musical instrument...
متن کاملAudio-visual multilevel fusion for speech and speaker recognition
In this paper we propose a robust audio-visual speech-andspeaker recognition system with liveness checks based on audio-visual fusion of audio-lip motion and depth features. The liveness verification feature added here guards the system against advanced spoofing attempts such as manufactured or replayed videos. For visual features, a new tensor-based representation of lip motion features, extra...
متن کاملAudio-Visual Multimodal Fusion for Biometric Person Authentication and Liveness Verification
In this paper we propose a multimodal fusion framework based on novel face-voice fusion techniques for biometric person authentication and liveness verification. Checking liveness guards the system against spoof/replay attacks by ensuring that the biometric data is captured from an authorised live person. The proposed framework based on bi-modal feature fusion, cross-modal fusion as well as 3D ...
متن کاملAudio-visual mutual dependency models for biometric liveness checks
In this paper we propose liveness checking technique for multimodal biometric authentication systems based on audiovisual mutual dependency models. Liveness checking ensures that biometric cues are acquired from a live person who is actually present at the time of capture for authenticating the identity. The liveness check based on mutual dependency models is performed by fusion of acoustic and...
