Research
Learning Bandwidth Expansion Using Perceptually-Motivated Loss
We introduce a perceptually motivated approach to bandwidth expansion for speech. Our method pairs a new 3-way split variant of the FFTNet neural vocoder structure with a perceptual loss function, combining objectives from both the time and frequency domains. Mean opinion score tests show that it outperforms baseline methods from both domains, even for extreme bandwidth expansion.

Interests
I love music and believe good music comes from all genres, instruments, and people. I produce music using a mix of digital/analog synthesis (feel free to check out my SoundCloud). I play piano (my current goal is to master Chopin's Ballade No. 1 in g minor) and am teaching myself guitar.
When not geeking out over machine learning or music theory, I enjoy playing tennis and watching reruns of Friends.
