          <h3>End-to-End Diffusion</h3>
          <img src="architecture.png"  alt="" class="center">
          <br />
          We train a series of diffusion models that are applied in succession to generate the final music clip.
          <br>
          <h3>Pseudo-labeling for Training Data Generation</h3> 
          <img src="pesudolabeling.png" alt=""  class="center">
          <br />
          The training set is generated by pseudo-labeling a large unlabeled set of music audio using two deep models. 
          A large language model is used to generate a large set of generic music descriptive sentences as caption candidates. 
          A pre-trained music-text joint embedding model is used to assign the captions to each music clip via zero-shot classification.
          <br>
          <h3>Generative Ability</h3>
          Noise2Music models are able to go beyond simple music label conditioning
          and handle complex, fine-grained semantics.

      <h2>Broader Impact</h2>
      <span>          
        We believe our work has the potential to grow into a useful tool for artists and content creators that can further enrich their creative pursuits. To live up to this promise, more work is needed with musicians and other stakeholders to develop models into a meaningful co-creation tool. 
        <br /><br />
        We acknowledge the limitations of the proposed model. In particular, large generative models learn to imitate patterns and biases inherent in the training sets, and in our case, the model can propagate the potential biases built in the text and music corpora used to train our models. Such biases can be hard to detect as they manifest in often subtle, unpredictable ways, which are not fully captured by our current evaluation benchmarks. Demeaning or other harmful language may be generated in model outputs, due to learned associations or by chance.
        <br /><br />
        Beyond this, we recognize that musical genres are complex and key musical attributes are contextual and change over time. Training data reflect a limited corpus of musical samples and genres, given uneven recording and digitization of samples from global musical cultures. How music is categorized and labeled can essentialize genres; and these labels may be constructed and applied without the participation of communities. We caution readers not to presume each sample can generalize to an entire musical genre or one label can capture the diversity of musical genres produced within a region (i.e. “Latin music” contains a broad range of cultures and styles). Moreover, musical samples may sound "authentic" to those outside these communities, as nuances in musical traditions need trained ears/cultural knowledge to recognize. In generating vocals, there may be possible caricatures, “mock accents,” parodies, or other demeaning linguistic harms (e.g., "mock Black singing" in a request for "soulful vocals'' or "mock Spanish" in a Latin music request) that arise in text prompts requesting cultural or religious musical genres, or genres that emerged as part of the political struggles of certain communities (e.g., Black American music, Nueva canción, Chicano folk, Brazilian Tropicalismo, Sufi Qaw).
        <br /><br />
        As is with any other technology, the result of our research can be misused or abused. We acknowledge the risk of potential misappropriation when the created content exactly matches examples in training data. Duplication checks are a built-in part of our current pipeline of producing and releasing examples, and will continue to be for any future work.
        <br /><br />
        Efforts for identifying potential safety issues and addressing them are important components for improving these generative models. Until there is a more clear understanding of the limitations and risks, we do not intend to release the model.
