MelT: A Portable, Single-GEMM Mel Audio Frontend via Non-Uniform DFT with Measured Latency and Energy Gains on GPUs

Augusto Camargo, Marcelo Finger

The paper introduces MelT, a single‑stage Mel audio frontend that replaces the traditional STFT‑based pipeline with a precomputed non‑uniform DFT applied via GEMM, achieving 1.6‑3.…
