Clean Audio for TV broadcast: An Object-Based Approach for Hearing-Impaired Viewers

May 18, 2015

open access

Update: I just uploaded a new journal article published last month in the Journal of the Audio AES Journal paperEngineering Society. Happily the University of Salford paid for it to be open access as part of their open access strategy so it’s freely available for anyone to download.

The paper (right) is a follow up to my PhD research, which was all about looking at methods to improve TV sound for people with hearing impairments by enabling what is usually known as ‘clean audio’ – helping hearing impaired people to hear speech more clearly than is often the case.

The early part of the PhD was funded by the ITC and then Ofcom, later parts were carried out as part of the EU funded FascinatE project which I’ve written about on this blog before. The FascinatE project utilised what is known as object-based audio to implement interactive 3D (with height) spatial audio which would vary depending on the user-defined visual scene. The FascinatE viewer could have free navigation of the visual scene and point their ‘camera’ to whatever part of the video panorama was of interest to them. The audio ‘objects’ rotated and/or moved to match the chosen view.

In the more recent clean audio work above Read the rest of this entry ?

an Audio Augmented Reality Query

February 9, 2012

I have thought occasionally about wayfinding applications of surround sound presented over headphones – using a bunch of filters (called Head Related Transfer Functions) to replicate the experience of 3D sound but using only a stereo signal over headphones. As you may know using HRTF you can get very good surround sound – it’s used by games such as Papa Sangre – but can be made more accurate and effective with customised filters for an individual person.

The RNIB see benefit in looking at audio related wayfinding apps for mobile phones with GPS and wanted to know what I could do for them so I started thinking about how sighted people find their way round a strange place.

Then I thought about hardware to make it happen. It would need Read the rest of this entry ?

BVE2012 Looking good, who’s going? Time to register…

One seminar for me to catch is “Sound of the Games”, Dennis Baxter, Sound Designer for 2012 London Olympics. Interesting if you caught him on radio 4, The Sound Of Sport you’ll know what I mean. Also Immersive audio systems explored – Sound for 3D with Pieter Schillbeeckx, Soundfield and a friend and neighbour of mine at MediaCityUK, Chris Pike from BBC R & D.

Games People Play: a post from the ETC

December 10, 2011

The Last Message - A Kinect platform-game that tells a story of the journey of a waveform. The player controls the the amplitude and frequency of the waveform using both arms, and must guide it to the broadcasting tower — with Brian Lee, Ruijie Liu, Shibli Mansuri and Scott Chen. From the Fall 2011 BVW Show

As promised, this post comes from Pittsburgh where I’m working for a week as a guest of Carnegie Mellon University’s Entertainment Technology Center (ETC).

The inimitable Don Marinelli, Executive Producer of the ETC

The ETC was created by the inimitable Don Marinelli and the late Randy Pausch combining skills in drama and computer science to produce game designers and “entertainment technologists”. It is a unique place that I have written about before. Students here study on a largely project based masters programme that aims to produce graduates that thrive on cross disciplinary team based project work

I’ve been invited here to do some workshops on 3D audio and to inspire students to incorporate some of the work we do at the Acoustics Research Centre at Salford into their projects and Read the rest of this entry ?
