Speech Dereverberation Book

Speech DereverberationThe edited book Speech Dereverberation offers the reader an overview of the subject area, as well as an in-depth text on the advanced signal processing involved. The edited book benefits the reader by providing such a wealth of information in one place, defines the current state of the art and, lastly, encourages further work on this topic by offering open research questions to exercise the curiosity of the reader. It is suitable for students at masters and doctoral level, as well as established researchers.

World's first dereverberation plugin for Pro Tools

Imagine your are making an audio recording on site and there is a large distance between the desired speaker and microphone, e.g., due to the microphone position. In this case, the desired sound is distorted by ambient noise and reverberation. In general, it is extremely hard to cleanup the recording.

NML RevCon-RR is a plugin for Pro Tools, a professional digital audio workstation platform, that allows you to reduce reverberation. The plugin already has been used for post-production work of several movies, TV shows, and TV commercials. The dereverberation algorithm used in this plugin was invented by NTT Communication Science Laboratories in Japan and is primarily based on [1].

A sound demo and product information can be found here.

International Workshop on Acoustic Echo and Noise Control

Established in 1993, the International Workshop on Acoustic Echo and Noise Control (IWAENC) is the leading workshop in the signal processing community addressing issues including:

- Adaptive filtering algorithms and structures for echo and noise control
- Noise and reverberation reduction techniques
- Active noise control, sound reproduction and hearing aids
- Transducers and acoustic front-ends
- Hardware and real-time issues
- Speech-databses and software tools
- Mulitrate filter banks and subband systems
- Systems for stereophonic echo and noise control
- Microphone arrays and array signal processing
- Sound enhancement and sound separation
- Temporal segmentation of signals
- Voice activity detection and double-talk detection
- Noise and acoustic environments and characteristics

The IWAENC workshop is held every even year and consists of a three day program that includes poster presentations of recent work and latest results, keynote talks, and demonstrations. Almost all IWAENC proceedings are available at www.iwaenc.org.

The next IWAENC will be hosted by Prof. Sharon Gannot and Prof. Israel Cohen in Tel-Aviv (Israel) in 2010. Please keep an eye on their website.
