AURA-DSP Autonomous Multi-Agent Audio Restoration

AURA-DSP represents a structural shift in Digital Signal Processing by integrating autonomous multi-agent orchestration into audio engineering. It is designed to solve the inherent fidelity limitations of Generative AI audio (e.g., Suno, Udio), specifically targeting aliasing artifacts and transient degradation. The system utilizes AMD ROCm and vLLM to power an agentic pipeline that executes high-order oversampling to eliminate aliasing. By processing signals at higher internal rates, AURA-DSP prevents high-frequency folding that creates metallic artifacts in synthetic audio. Crucially, the AERO step (Acoustic Enhancement) employs autonomous agents to correct phase alignment issues. In many AI models, non-linear phase shifts smear the group delay of fast-attack signals, leading to a loss of transients (the "punch" in drums and percussion). AURA-DSP identifies these phase inconsistencies and applies linear-phase FIR filtering and time-alignment kernels to reconstruct the original impact of the audio. By automating source separation (ACE step) and applying quantitative spectral corrections, the framework transforms "flat" AI outputs into professional-grade stems. This eliminates the manual bottleneck of traditional DAWs and provides a scalable, intelligent infrastructure for high-fidelity audio production.
