Mason L. Wang

I am an EECS PhD student at MIT CSAIL, where I am working with Professor Anna Huang. I am currently on leave working at xAI, where I lead the Audio Understanding team. I am interested in audio, generative modeling, and signal processing.

I received my master's in Electrical Engineering at Stanford University working at the Stanford Vision and Learning Lab. I was advised by Jiajun Wu and Mert Pilanci.

Publications
	Latent Fourier Transform Mason L. Wang, Cheng-Zhi Anna Huang ICLR, 2026 (Oral, Top 1.1% of Submissions) paper / website / code / arkiv We introduce novel frequency-based controls for audio generative models, by manipulating latents in the frequency domain.
	Subtractive Training for Music Stem Insertion Using Latent Diffusion Models Ivan Villa-Renteria, Mason L. Wang, Zachary Shah, Zhe Li, Soohyun Kim, Neelesh Ramachandran, Mert Pilanci ICASSP*, 2025 paper / examples We use a dataset of full-mix songs, stem-subtracted songs, and LLM-generated edit instructions to train a stem editing/insertion diffusion model.
	Hearing Anything Anywhere Mason L. Wang, Ryosuke Sawata, Samuel Clarke, Ruohan Gao, Elliott Wu, Jiajun Wu CVPR, 2024 video / paper / website / dataset / code / arkiv We create a method of capturing real acoustic spaces from 12 RIR measurements, letting us play any audio signal in the room and listen from any location/orientation. We develop an 'audio inverse-rendering framework' that allows us to synthesize the room's acoustics (monoaural and binaural RIRs) at novel locations and create immersive auditory experiences (simulating music).
	SoundCam: A Dataset for Finding Humans Using Room Acoustics Mason L. Wang, Samuel Clarke, Jui-Hsien Wang, Ruohan Gao, Jiajun Wu NeurIPS Datasets and Bencmharks, 2023 project page / video / arXiv Humans induce subtle changes to the room's acoustic properties. We can observe these changes (explicitly via RIR measurement, or by playing and recording music in the room) and determine a person's location, presence, and identity.
	RealImpact: A Dataset of Impact Sound Fields for Real Objects Samuel Clarke, Ruohan Gao, Mason L. Wang, Mark Rau, Julia Xu, Jui-Hsien Wang, Doug James, Jiajun Wu CVPR, 2023 (Highlight, Top 2.5% of Submissions) project page / video / arXiv Everyday objects possess distinct sonic characteristics determined by their shape and material. RealImpact is the largest dataset of object impact sounds to date, with 150,000 recordings of impact sounds from 50 objects of varying shape and material.
