Hi, I'm Chris.

I love everything to do with sound.

Welcome to my site.

About

Personal Profile

Christopher Landschoot

I love everything involving music, technology, and sound. I work as a machine learning engineer researching and developing new deep learning systems for a range of audio and music technologies. I have also consulted on the acoustical design of the built environment, with projects ranging from performance venues to recording studios. My work and research include developing and implementing models and algorithms to perform audio source separation, music sample generation, sound source detection, zero-shot classification, music fingerprinting, audio enhancement, and binaural audio externalization among others. I have also developed other software to measure acoustics metrics, model wave behavior, process spatial audio, and create audio effects plugins.

When I am not focused on the design of sound and technology through my work or research, I am writing, recording, or performing music. I play guitar (electric, acoustic, bass), percussion, piano, and even dabble with the banjo. My artist name is After August (check me out on Spotify), and I play musical styles from rock to jazz to folk and everything in between. I love all types of music.

I live in Chicago with my wife, Steph, our son, Myles, and our little dog, Queso. Steph works as an interventional radiology nurse at Northwestern Memorial Hospital assisting with groundbreaking operations daily and Queso takes naps on my lap daily as I work at my desk. I play in the local kickball league and love to escape to the Finger Lakes and Adirondack Mountains in NY each summer for some hiking, kayaking, and time with the family.

Launched a new product offering by developing a room acoustics auralization system in Max/MSP and MATLAB that can encode, convolve, and decode higher-order ambisonic signals in real-time.

Reduced acoustic design time on projects by updating company protocols to standardized acoustic analysis and testing methods, as well as designing bespoke analysis tools in MATLAB, increasing company-wide efficiency, accuracy, and capabilities of acoustics measurements and analysis.

Rensselaer Polytechnic Institute

Research AssistantAugust 2017 - August 2018

Researched and patented new technology, by creating a novel machine learning algorithm in MATLAB that estimates the directions of arrival and relative levels of an arbitrary number of sound sources through a multi-level Bayesian framework, using spherical beamforming with a spherical microphone array.

Projects and Writing

Open-Source Audio & Machine Learning Projects and Writing

Open-Source Projects

Tiny Audio Diffusion

Built a lightweight system that applies waveform diffusion (1D U-Net) to generate short audio samples (such as drum sounds) to be trained and run on a low-level consumer GPU (<2GB VRAM). The purpose of this project is to provide access to waveform diffusion code for those interested in exploration but who have limited hardware resources.

Music "Demixing" (Sound Source Separation)

Built a music source separation system in Python using a band-split recurrent neural network (RNN) framework based on a research paper to compete in AIcrowd's Sound Demixing Challenge 2023. Four models (voice, bass, drums, other) were trained on a Google Cloud Platform GPUs with W&B tracking and resulted in an improvement over the baseline model on the "Label Noise" track by 42%.

LogWMSE (PyTorch)

Developed a PyTorch implementation of logWMSE, an audio quality metric and loss function. It addresses shortcomings of common audio metrics, like digital silence targets, making it effective for training and evaluating audio source separation and denoising models.
