Revisiting Input Time-frequency Representations in Multi-pitch Estimation for Vocal Ensembles

Junyoung Koh, Hao-Wen Dong

Multi-pitch estimation in vocal ensembles is challenging because singers occupy overlapping pitch ranges and often sing at closely spaced fundamental frequencies, causing their har…

Neural Audio Codec for Robust Audio Deepfake Detection

Jungwoo Kim, Joonyong Park, Junyoung Koh +1

Audio deepfake detectors are typically evaluated on uncompressed audio, although real-world audio often undergoes low-bitrate coding. In this work, we investigate how audio coding…

Probing Token Spaces under Generator Shift in AI-Generated Music Detection

Joonyong Park, Jungwoo Kim, Junyoung Koh +1

AI-generated music detectors can appear robust on standard benchmark splits, yet their deployments require transfer to generator sources absent during training. We study this probl…

Instrumental Text-to-Music Generation with Auxiliary Conditioning Branches

Junyoung Koh

Text-to-music generation has advanced rapidly, with modern autoregressive and diffusion-based models producing convincing music from natural-language prompts. However, much of this…

MCJudgeBench: A Benchmark for Constraint-Level Judge Evaluation in Multi-Constraint Instruction Following

Jaeyun Lee, Junyoung Koh, Zeynel Tok +2

Multi-constraint instruction following requires verifying whether a response satisfies multiple individual requirements, yet LLM judges are often assessed only through overall-resp…

Jamendo-MT-QA: A Benchmark for Multi-Track Comparative Music Question Answering

Junyoung Koh, Jaeyun Lee, Soo Yong Kim +5

Recent work on music question answering (Music-QA) has primarily focused on single-track understanding, where models answer questions about an individual audio clip using its tags,…

AIBA: Attention-based Instrument Band Alignment for Text-to-Audio Diffusion

Junyoung Koh, Soo Yong Kim, Gyu Hyeong Choi +1

We present AIBA (Attention-In-Band Alignment), a lightweight, training-free pipeline to quantify where text-to-audio diffusion models attend on the time-frequency (T-F) plane. AIBA…
