Cocktails, but no party: multipath-enabled private audio
Yu-Jeh Liu, Jonah Casebeer, Ivan Dokmanić
We describe a private audio messaging system that uses echoes to unscramble messages at a few predetermined locations in a room. The system works by splitting the audio into short…
Separake: Source Separation with a Little Help From Echoes
Robin Scheibler, Diego Di Carlo, Antoine Deleforge +1
It is commonly believed that multipath hurts various audio processing algorithms. At odds with this belief, we show that multipath in fact helps sound source separation, even with…
Pyroomacoustics: A Python package for audio room simulations and array processing algorithms
Robin Scheibler, Eric Bezzam, Ivan Dokmanić
We present pyroomacoustics, a software package aimed at the rapid development and testing of audio array processing algorithms. The content of the package can be divided into three…
FRIDA: FRI-Based DOA Estimation for Arbitrary Array Layouts
Hanjie Pan, Robin Scheibler, Eric Bezzam +2
In this paper we present FRIDA---an algorithm for estimating directions of arrival of multiple wideband sound sources. FRIDA combines multi-band information coherently and achieves…
Raking the Cocktail Party
Ivan Dokmanić, Robin Scheibler, Martin Vetterli
We present the concept of an acoustic rake receiver---a microphone beamformer that uses echoes to improve the noise and interference suppression. The rake idea is well-known in wir…
