Source: Text-to-Audio Generation using Instruction Tuned LLM and Latent Diffusion Model

Summary
The paper presents TANGO, a text-to-audio generation system that uses an instruction-tuned large language model as the text encoder and a latent diffusion model for generating high-quality sound effects, speech and music.

Facts

🔊 TANGO generates text-conditional sound effects, human speech, and music.

💻 TANGO’s latent diffusion model (LDM) is trained on 63x less data than the baselines, yet produces superior sound quality.

🎧 TANGO’s LDM is trained with text supervision from an instruction-tuned large language model, FLAN-T5.

🎙️ TANGO’s major components include a textual-prompt encoder, LDM, and mel-spectogram/audio VAE.

🔊 TANGO uses audio pressure level-based sound mixing for training set augmentation, improving upon random mixing used by prior methods.

Summary
The power supply is providing 6.18 volts to a board with 5v chips. The device in question is a tabla drum machine, and the power supply is using line level AC. The user wants to power the board directly with a barrel plug.
