Introduction

Did you know that AI can already create amazing music? Not only can we do this in a research context, coding it ourselves, but there are now websites where you can just enter a quick text description of what you want and get a music sample. The best thing is that you can try it for free for up to 20 tries a month. In this article, we will dive into the world of AI music generation and explore how Stable Audio, a new model developed by Stability AI, is revolutionizing the way we create music.

AI Music Generation: An Overview

Generative approaches in AI, especially those involving complex signals like images and sound, have gained significant attention in recent years. One popular approach is the use of diffusion networks, such as Stable Diffusion. These networks take noise as input and iteratively generate an output by learning to add noise repeatedly until it converts back to a real image or sound. This process involves training the model in reverse, starting with the desired output and corrupting it little by little. Through millions of trials and examples, the model learns the noise patterns and is able to generate high-quality outputs.

The Power of Diffusion Networks

Stable Diffusion has been successful in generating realistic images by leveraging the latent information present in the initial sample. But how does this apply to the generation of sound? Surprisingly, sound is quite similar to images, as it can be converted into a magnitude spectrum, which visually represents the frequency content of the sound over time. This similarity allows us to use a similar network architecture to encode sound and generate high-quality outputs.

Stable Audio: Transforming Text into Music

Stability AI has developed Stable Audio, a model that takes input from text and transforms it into a musical representation. Just like Stable Diffusion does for images, Stable Audio is able to understand the text and generate a corresponding musical output. The key to this transformation lies in the Clap Text Encoder, a network specifically trained to convert text input into a latent representation suitable for the generative model. This encoder learns from hundreds of thousands of examples and can effectively extract the most important features of the sound from the original input.

The Clap Text Encoder: Converting Text into a Good Representation

The Clap Text Encoder plays a crucial role in the Stable Audio model. It takes the text input and transforms it into a compressed representation that captures the essence of the sound. This representation is then fed to the generative model, which reconstructs the sound based on the latent information. By training the encoder to perform this transformation, Stable Audio is able to generate music that accurately represents the input text.

The VAE Decoder: Upscaling Sound Quality

Similar to the latent diffusion model used in Stable Diffusion, Stable Audio also operates in a compressed representation of sounds for training and inference efficiency. To enhance the sound quality, Stability AI has incorporated a VAE (Variational Autoencoder) decoder. This decoder focuses on upscaling the sound, just like upscaling images. By combining the latent information from the encoder with the VAE decoder, Stable Audio is able to generate high-fidelity music that sounds pleasing to the human ear.

Dealing with Variable Output Length: Generating Any Song You Want

Unlike images, music is not fixed in space. A song has a duration that can vary, and generating any desired song requires a system that can handle variable output lengths. Stability AI tackled this challenge by providing the model with additional information during training. By including parts of the song, their start time, and total length as input, the model learns to understand the desired length of the generated song and what to generate next. This enables Stable Audio to create an array of songs of varying lengths, with customized riffs, endings, and other musical elements.

Stable Audio in Action: Results and Samples

The implementation of Stable Audio has yielded impressive results. All the music used in this article was generated using this model, with zero human involvement. The AI-produced music showcases the power and potential of Stable Audio. You can listen to the samples and results shared by Stability AI on their blog post, experiencing firsthand the quality of music that can be generated through AI.
