This may sound niche at first, but soundbars and smart speakers in particular are increasingly making use of this technology. The stereo upmix should also be mentioned briefly here. However, smart speakers and soundbars will help to make 3D mixes more accessible in the living room in the future. But this is reserved for people who have a hi-fi system with a multi-channel setup. With Dolby Atmos, for example, and the aforementioned streaming providers, the audio objects provide the option of playing these works on several speakers. Of course, 3D music can not only be produced via headphones. Here is a typical example of “8D music”, where only the master file of the song is moved around the listener using a binaural panner: Although this is nothing special from a production point of view (you can find out why here ), it seems to have hit a certain nerve given the sometimes extremely high click numbers on YouTube. Not to be neglected is also the trend known as “8D Audio”. Those of you who have an Amazon Music HD account can search for the “Best of 3D Audio” playlist for corresponding audio samples or read the blog entry above. Speaker playback is currently possible with soundbars like the Sennheiser Ambeo Soundbar or smart speakers like the Amazon Echo Studio. The playback of these object-based formats can be done via speakers, as well as binauralized via headphones. Currently, the audio formats used are AC-4 (Dolby Atmos Music) and MPEG-H (Sony 360 Reality Audio). Meanwhile, some streaming services offer music mixed and mastered specifically in 3D audio, for more details click here. Therefore, it probably makes more sense to address the topic in terms of usage. Probably every 3D audio technology has been applied to music before. Since installations cannot be experienced here online, I refer to this interesting article about the Ambisonics installation “Kaleidoscope of Rooms”.Īlso worth mentioning here is Innsbruck’s Audioversum – a museum all about audio and walk-in sound installations.ģD audio in music is, as can probably be guessed, a vast subject. But spatial sound wave (wave field synthesis) is also a popular medium. ![]() For technical implementation, channel-independent formats such as Ambisonics can be used. In terms of 3D audio, these are usually circular or dome-shaped speaker arrangements that can create enveloping experiences. Sound installations are of course difficult to pigeonhole, but they should be briefly mentioned here anyway. Here you can – surprise, surprise – be served in a virtual barbershop: This is the only way to accurately represent spatial impressions.Ī famous piece that can already be called a “classic” is the Virtual Barber Shop. Binaural audio recordings are intended for playback over headphones, as there must be no crosstalk between the speakers. Therefore, binaural stereo is used here, which can either be recorded using binaural microphones or reproduced using appropriate software. These audio games can usually be enjoyed over headphones – so they can be listened to at home and on the road without any major hurdle. Due to the spatial imaging possibilities of sound, 3D audio offers even more options to involve the listener in a captivating story or environment. The latter, however, will be considered separately as the implementation depends strongly on the intended effect.īut not only the immersion is enhanced, but there are also more narrative possibilities in terms of storytelling. ![]() radio plays, soundscapes, ambient recordings, ASMR, and of course music. Radio Plays, Sound Experiences without visual referenceĪudio content that is consumed without an additional visual stimulus can benefit immensely from 3D audio technologies. This way you can directly experience what is being talked about. After a short description regarding the used audio and playback formats, audio examples or further links follow. Each medium is treated as a separate chapter, which in turn is divided into individual categories. In the end, I decided to differentiate according to “playback media”. ![]() It is not so easy to find a structure here, because there are many overlaps. Also, you can get some inspiration right away, because the application areas are absolutely creative, diverse and far from exhausted. So the time has come to get overwhelmed! Therefore, with the help of the following overview, some light should be brought back into the darkness. 3D audio has now arrived in many forms to the consumer sector.
