Examples of binaural audio

Listen to the following examples (you have to wear headphones, of course!)

Virtual Barbershop:

3D matchbox:

New York City in 3D audio (this is actually a mini documentary with examples of recordings in binaural audio):

Finally, an example of synthetic binaural audio (convolution with HRTFs):


BinauralSIM released!

BinauralSIM_logoWe have the pleasure to present the beta release of BinauralSIM


BinauralSIM allows to simulate binaural recordings using headphones.

Try out your own or the Kemar HRIR and test your own signals. The software allows you to compare stereo vs binaural performance in real time.




BinauralSIM has been developed by Nadine Kroher and founded by PLA D’AJUTS DE SUPORT A LA QUALITAT I LA INNOVACIÓ DOCENTS PLAQUID, Universitat Pompeu Fabra, 2015.

Binaural Reproduction using Loudspeakers

Can we listen to binaural recordings through normal speakers?

Of course. Even when binaural recordings for headphones still sound fantastic on speakers – you just won’t be able to get the 3D effect. That’s because as the sound travels through room, the left and right channels mix and your brain can’t make sense of the directional cues (cross-talk). Various works “has been/are being” developed to cancel this crosstalk and thus, allow proper 3D listening on speakers.

In this lecture, we revise the principles of Transaural recordings and learn the basis of CrossTalk Cancellation proposed by Schroeder. The contents of the lecture and the related references are depicted below:

Binaural Reproduction using Headphones

Binaural recordings are reproductions of sound “the way human ears hear it”. Actually, the word “binaural” literally just means “using both ears.” When you listen to a binaural recording through headphones, you perceive distinct and genuine 360° sound.

It’s the purest, most natural way to record and listen to music.

In this lecture, we cover the following topics about Binaural recording using Headphones. Further information can be found in the related references.
