Here we introduce Aerotak: A system for audio analysis and perception enhancement that allows speech perceivers to listen with their skin. The current system extracts unvoiced portions of an audio signal representative of turbulent air-flow in speech. It stores the audio signal in the left channel of a stereo audio output, and the air flow signal is stored in the right channel. The stored audio...

The Photoliptophone was a system developed by Argentinean inventor Fernando Crudo in the 1930s. The system allowed recording audio waveforms on radiographic plates, so that they could be printed on paper. The aim of the system was reducing the distribution cost of audio copies by including the printed waveforms in magazines and newspapers. The Photoliptophone obtained patents in thirty countrie...

A system for speaker-based audio-indexing and an application for speaker-tracking in broadcast news audio are presented. The process of producing an indexing information in continuous audio streams based on detected speakers is composed of several tasks and is therefore treated as a multistage process. The main building blocks of such an indexing system include components for an audio segmentat...
