Virtual reality for your ears – Binaural sound

What’s the difference between spatial audio and binaural sound?

Spatial audio is when you listen to 3D sound on a loudspeaker it also includes listening to 3D sound on some headphones. But if listen to 3D sound on just headphones it is referred to as binaural sound.

Here are some examples, wear your headphones!

Rob Da Bank’s headphone special – Recorded in 3D.

BBC Proms recorded in binaural sound.

How is this 3D sound created?

Example of object based audio

Object based audio is one way spatial audio is used in media. Here’s an example: The audio “objects”, individual actors, spot effects and atmos mics, are fed to the home as one continuous data stream. The producer has decided during the mix where each object is to be placed around the listener.

Why use it?

Immersion, the listener is brought further in to the heart of the story, and triggering greater thrills and connections to the scene. This drags the listener in and if used with video is even more effective. We hear a great deal with our eyes! Get actors to look off screen behind the viewer and place a sound behind them, and the binaural effect is very powerful.

“Binaural audio has grown in popularity due to one huge thing VR, Virtual Reality”


Recording voiceover for an e-learning course

I have been recording some podcasts for a leadership programme. One of the modules was Giving Feedback.

In order to record the voiceover I used Recordium on the iPad, the free version (sound quality was good, in comparison to the microphone attached to my laptop), and converted the mp4 file to an mp3 using, it was then edited using Audacity (free sound editing software).

Any free audio recording or editing software that you’d like to share?

Adding audio to e-learning

Another project that I am working on is called iProduct, this is linked to the other Product Knowledge project and within this piece I have used voiceover.

I am facing challenges whilst deploying the course, as not all desktops have the sound card enabled and not all delegates have a headset.

Writing audio scripts is similar to radio scripts, audio scripts should have a hook that sparks the imagination and entices the learner.

Audacity is a free audio recording software and you can edit the sound within this software.
