about
I am a passionate researcher based in Jiangsu, China, working at audio signal processing, bioacoustics and machine learning. I graduated from Queen Mary University of London (QMUL) in 2023 and have been the founder of Mantle Sound since 2025.
My work spans from developing neural audio codecs for geophone recordings to creating environmental field recordings. I have conducted field recording expeditions across China, the UK, France, and Switzerland since 2023, capturing the acoustic ecology of high-altitude environments.
research
Captured ecological soundscapes using equipment from interharmonics Wien. Built annotation workflow for soundscape corpus. Trained EnCodec-based neural audio codec with Transformer for ultra-low bitrate compression.
Developed two-stage anonymisation system combining McAdams coefficient DSP and VAE-GAN timbre transfer. Trained on Flickr 8k Audio Caption Corpus. Integrated into ZEBRA framework with improved EER and voice distinctiveness metrics.

sound works
Interactive sound installation that sonifies Moka Pot movements using IanniX, Arduino, and Max/MSP
code
Built autoencoder-based denoising pipeline for bird song recordings from Warblrb10k dataset. Evaluated using SDR/SIR/SAR metrics. Integrated with CNN classifier for improved bird presence classification.
