Large-scale multimodal generative modeling has created milestones in text-to-image and text-to-video generation. Its application to audio still lags behind due to two main reasons: the lack of large-scale datasets with high-quality text-audio pairs, and the complexity of modeling long continuous audio data. In this work, we propose Make-An-Audio with a prompt-enhanced diffusion model that addresses these gaps by 1) introducing pseudo prompt enhancement with a distill-then-reprogram approach which alleviates the data scarcity by using weekly-supervised data with language-free audios; 2) leveraging spectrogram autoencoder to predict the self-supervised audio representation instead of waveforms. Together with robust contrastive language-audio pretraining (CLAP) representations, Make-An-Audio achieves state-of-the-art results in both objective and subjective evaluation. Moreover, we present its controllability with classifier-free guidance and generalization for X-to-Audio with "No Modality Left Behind", for the first time unlocking the ability to generate high-definition, high-fidelity audios given a user-defined modality input.

Personalized Text-to-Audio Generation
It allows to inject unique objects into new scenes, transform them across different styles. For instance, when asked to generate ``baby crying'' given the initial sound of ``thunder'', our model produces realistic and faithful audio describing ``a baby cries in the thunder day".
