Anechoic recordings

Anechoic recordings for auralisation are available for download further below on this page. The WavePack Installs (which require that Odeon Auditorium, Odeon Combined or the free Odeon Combined Demo has been installed) will automatically enrich your default ODEON Rooms and WaveSignals folders with orchestra rooms and samples that you can use to produce auralisations with your rooms.

To make the rest of the available recordings accessible through for ODEON auralisation, you have to unzip and copy-paste the content inside the WaveSignals folder of your ODEON installation (eg. C:\ Odeon15Combined\ WaveSignals\). Please see the readme.txt file or this file when installation finishes.

We also have ODEON zip files available, which are packages that contain a complete model, where we have a room set up with anechoic recordings. These models come ready to produce an auralisation.

Installation of audio recordings for orchestra auralisation 

Anechoic orchestra recordings are installed with separate installation files that can be downloaded from the following links.

Installation of other audio recordings

From Helsinki University of Technology, high-quality recordings of a symphony orchestra are available. Musicians are recorded one by one in an anechoic chamber. Click here to get the TKK recordings.

From Dipartimento di Ingegneria, Università di Ferrara anechoic recordings of singing and ancient instruments used in the CAHRISMA and ERATO projects.


Noise Signals, various noise signals including the common types of white and pink noise.

Crowd Sounds, contributions from the Erato project which ODEON A/S participated in. This file contains wave files with sounds of Supporting, Opposing, Crying and Clapping people as well as various idle sounds.

Cocktail Party, outdoor recordings of a cocktail party, it could maybe be used as café or canteen auralisations, but the recording is not of the best quality and contains some disturbing tones.

Background Speech, outdoor recordings of multiple people talking in Danish (mostly women).

Harvard Word List, semi-anechoic speech recordings of both male and female voices. The list, supervised by Neil Thompson Shade (, is useful for audio system evaluation material.

Additional contributions would greatly be appreciated! You may send us anechoic recordings to
