The Interactive Audio Lab

Welcome to the Interactive Audio Lab, headed by Bryan Pardo. We are in the Electrical Engineering and Computer Science Department of Northwestern University . We apply machine learning, signal processing, natural language processing, and database search techniques to make new auditory tools and interfaces.

Current Projects

	Tunebot A music search engine you can sing to
	Audio Imputation Estimate missing information in audio
	Spatial Source Separation Amplify sounds coming from a particular direction
	REPET Separation by repetition, by repetition, by repetition, ...
	Adaptive User Interfaces Don't learn the tool, let the tool learn you
	Soundprism Separate music sources in real time with the help of a musical score
	Score Alignment Learn about the music
	Music Story Make videos from music
	Multi-pitch Estimation & Streaming Track more than one pitch at once

SynthAssist is a tool for programming audio synthesizers using using similar example recordings, such as vocal imitations. Watch a video here.
Mixploration is an audio mixing tool for finding diverse mixes. Watch a video here.
Just sing to Tunebot to find your song.
SocialEQ is a tool that learns the meaning of sound adjectives from you.
Toneboosters released TB EZQ, a zero-latency, VST-plugin implementation of our 2DEQ audio equilizer.

Bach10, a versitle polyphonic music dataset for Multi-pitch Estimation and Tracking, Audio-score Alignment and Source Separation.
Ground-truth Pitches for the PTDB-TUG speech pitch tracking dataset. The ground-truth pitches were calculated using Praat on the microphone signals.
Jazz Score/Performance Database, a database of MIDI recordings performed by professional Chicago jazz pianists using lead sheets, useful as training and validation data for a jazz score following program.
