Exploring Semiotic Interactions in Text-to-Audio: A Demonstration of Udio's Text- to-Audio Capabilities

This demo session explores the text-to-audio model Udio, demonstrating its remarkable ability to synthesize, define, and navigate semiotic relationships within musical interactions. The demonstration explores Udio's capacity to interpret and sonify textual descriptions, ranging from the harmoniously familiar to the deliberately jarring and incongruent. This investigation goes beyond merely showcasing the model's proficiency in generating traditionally "accurate" audio from stable descriptions; it serves as an exposition of Udio's role in transmuting and recombining textual signifiers to foster diverse sonic objects.

The session unfolds as an auditory symposium, where Udio translates a curated selection of textual prompts into their corresponding auditory manifestations. These prompts span a spectrum from clearly defined musical directives based on genres and artists, to semantically unstable descriptions and incongruent stylistic combinations, designed to stretch the model's interpretative faculties. By feeding Udio with this collage of linguistic constructions, we witness the transformation of text into sound, scrutinizing the emergent audio for instances of semiotic stabilization and destabilization.

By intentionally destabilizing the text-to-audio conversion, I aim to illuminate the potential of text-to-audio models not just to replicate and stabilize existing aesthetic norms but to diverge from them, articulating distinct aesthetic nuances. This session will engage listeners in a semiotic interaction, where the interplay of signifiers produces a polyphony of interpretations and associations, highlighting the model's double-edged capacity for both faithful representation and deterritorialized invention.

Throughout the experience, auditory études are paired with visual representations of their text prompts and underlying metatags and embeddings that Udio associates with the prompt., fostering a multimodal interaction that immerses participants in a dynamic process of semantic and semiotic schema assimilation. This pairing invites listeners to actively engage with these sonic objects, contemplating the reciprocal influence between textual input and musical output. The materials presented illustrate the methods and artifacts representative of the current state of text-to-audio technology, elucidating the processes of this novel form of semiotic transduction.

Participants are invited to engage in a process of active listening and reflection, becoming aware not only of the AI models' interpretive schemas but also of their own perceptual dispositions. This dual awareness fosters a rich environment for exploring inferentialism in action, as listeners navigate the space between linguistic input and musical output. As the AI-generated sonic objects unfold, listeners engage in "expectation arbitrage" – a cognitive process of constantly comparing their linguistically-primed expectations with the actual auditory input. This process challenges participants to reconsider the relationship between signifier and signified in both linguistic and musical domains, prompting a reevaluation of traditional musical paradigms and the nature of our structuralist imbrications and expectations. Listeners engaging with this experience might embark on an interpretative journey akin to the models themselves, associating textual and stylistic signifiers with established modes of musicking. This interaction exemplifies a form of Intersemiotic Musicking, combining Jakobson's (1959) idea of translating between sign systems and Small's (1998) concept of active musical engagement.

The process of decoding and interpreting these sound objects becomes an act of cognitive and cultural navigation, where listeners must reconcile their expectations, shaped by traditional musical paradigms, with the often surprising and idiosyncratic outputs of the AI model. The session

The process of decoding and interpreting these sound objects becomes an act of cognitive and cultural navigation, where listeners must reconcile their expectations, shaped by traditional musical paradigms, with the often surprising and idiosyncratic outputs of the AI model. The installation thus becomes a site of what Eco (1989) terms "open work," where the interaction between the AI's output and the listener's interpretation creates a multiplicity of associations.

This interaction exemplifies a form of Intersemiotic Musicking, combining Jakobson's (1959) idea of translating between sign systems and Small's (1998) concept of active musical engagement.

Moreover, the knowledge that these sounds are AI-generated adds another layer to the listening experience, invoking what Ihde (2007) terms "hermeneutic technics." Listeners are not just interpreting the sounds themselves, but also speculating about the AI's interpretative processes, engaging in a kind of "reverse engineering" of the machine's cognitive operations through its sonic output.This multi-layered interpretative process engages listeners in "meta-musical cognition" – thinking not just about the music itself, but about the processes of musical creation, interpretation, and perception at play here.

By showcasing Udio's multifaceted capabilities across diverse musical styles, this demonstration extends an invitation to reassess the interpretive frameworks shaping our understanding of music. It prompts the audience to contemplate and envision new possibilities within the realm of text to audio interactions. Moreover, it encourages a reflective engagement with the grammatization of AI tools, recognizing them not only as agents of potential homogenization but also as valuable tools for aesthetic disruption and inferential acknowledgment.

This exploration of Udio's capabilities contributes to ongoing discussions about AI's impact on musical interactions, aesthetics and the future of creative expression in the digital age.

Performance Details: The demo session presents a series of sound objects and études, each generated by the AI model Udio. These are presented consecutively, allowing the audience to focus on each output. Visitors to the session will experience these sound objects one after another, creating a clear and focused auditory narrative that demonstrates Udios's capacity for translating text into sound.

Each étude is presented alongside a visual display. This display includes two key elements: the original text prompt, and Udio's underlying metatags assimilated by the model from the prompt. These metatags and embeddings offer insight into Udio's internal representation and understanding of the prompt. This transparent presentation of Udio's interpretative layer illuminates the model's cognitive processes, showing how it deconstructs and reconstructs meaning from text to sound.

The arrangement is intentionally straightforward, with a deliberate focus on one sound object at a time to allow for complete immersion in the relationship between the textual prompt and its sonic interpretation. Visual projections of these prompts will accompany the audio, establishing a clear and direct semiotic link for the participants. Each sound object is presented alongside the visual display of the text prompt and metatags that generated it, offering a clear window into Udio's interpretative process. This side-by-side presentation allows observers to directly compare the input (text) with the output (sound), highlighting the model’s unique approach to translating written signs into sound objects.

The projected prompts not only contextualize the auditory experience but also invite reflective contemplation on the relationship between the signifier (text) and the signified (sound).

Relation to AI and Conference Theme:

This sessions serves as an incisive exploration of the theme 'Interconnections between Music AI and other fields,' specifically addressing the parallel processes of schema assimilation and semiotic signification conducted by both AI models and humans. By demonstrating the AI model capacity to interpret and generate music from text, the installation offers a reflective mirror on our cognitive processes, revealing the shared mechanisms by which we and the AI navigate a landscape of signifiers.

This session provides a compelling commentary on the structuralist view of language and meaning, suggesting that both AI systems and human interpreters operate within similar frameworks of understanding. It posits that our interaction with music is guided by underlying structures and systems of meaning-making that are analogous to the coded processes AI employs to render textual prompts into sound.

The installation underscores a significant theme of the conference by highlighting these interconnections, drawing attention to the inferential recognition and acknowledgement that occurs as both AI and human participants decode and ascribe meaning to musical signifiers. This session not only explores a significant paradigm shift in musical interactions through the text to audio modality, but also engages with a a deeper discourse on the structural parallels between machine learning algorithms and human semantic interpretation, thereby enriching the dialogue across disciplines of musicology, aesthetics, psychology, and AI development.

Ethics Statement

The session also invites critical reflection on the ethical implications of these technologies. Central to this discussion is the recognition that these AI models are trained on vast datasets comprising thousands of artists' works without consent, raising complex questions about authorship, attribution, and the nature of creativity in the age of machine learning.

It is important to acknowledge that Udio is currently involved in a legal battle in the United States, defending its practices under the fair use doctrine. This ongoing lawsuit highlights the tension between technological innovation and established copyright laws, underscoring the urgent need for legal and ethical frameworks to keep pace with advancements in AI. The case challenges us to reconsider how we define and protect creative works in an era where AI can generate new content based on learned patterns from existing art.

Unlike other audio manipulation techniques such as timbre transfer, where the original source material often remains discernible, the process of AI music generation creates what we might term "rhizomatic simulacra" in latent space. This concept, drawing on Deleuze and Guattari's (1987) rhizome and Baudrillard's (1994) simulacra, describes how the original musical "signs" are transformed into abstract, interconnected representations that often obscure their origins.

In this context, the AI-generated outputs exist not as a direct copy or even a clear derivative of any single work, but as a resynthesized and recombined representation of embedded clusters within the training data. This transformation challenges traditional notions of authorship and copyright, echoing Barthes' (1967) proclamation of the "death of the author" in a new, technologically-mediated context. The original artists' contributions are simultaneously everywhere and nowhere in the generated output, existing as a kind of spectral presence that informs but does not directly manifest in the final product.

This abstraction process is further complicated by the way certain models, such as Udio, handle artist references. By replacing artist names with underlying metadata in prompts, these systems create a layer of abstraction between the user's intent and the model's interpretation. This approach, while potentially mitigating direct copying, raises questions about the ethics of using artists' styles and data without explicit attribution or consent.

By foregrounding these ethical considerations, this session invites participants to engage critically with the outputs they experience. It challenges us to consider not just the aesthetic qualities of the generated music, but also its apparatus, provenance and the complex network of human creativity that underlies it.
