The year 2018 has been an interesting year in terms of audio. Most of the innovations have been happening over the years, but in 2018, these audio innovations have really begun to pique public interest.
Here is a list of a few trends that have been prominent this year.
True wire-free wireless audio
Trust Apple to invigorate and challenge older ways of doing things, with its introduction of truly wire-free earphones like the AirPods wireless earphones (back in 2016) in the wireless audio category seems to have made everyone join on the bandwagon. Everyone from audio manufacturers to millennials to grandma’s who confuse them with an electronic version of Q-tips that also play music, use them. So much so, “True wireless” experience is associated with this design with a lot of alternative brands and Chinese knock-offs also being widely available.
As a side-effect, several manufacturers like Motorola, HTC, Xiaomi and now even OnePlus are following suit by removing the 3.5 mm jacks from their smartphones altogether, much to the dismay of audio enthusiasts and purists who swear by the quality of wired audio over anything else.
If you are one of those kinds to lose your AirPods easily, here’s a “How not to lose your AirPods” video to help you out.
Putting AI in Audio
Gone are the good old days where a speaker was just a speaker. Nowadays audio manufacturers like to shove more than just good audio into good-looking boxes, we have speakers/earphones that talk to us. (As if we are in dire need of communicating with the world already flooded with chat programs in smartphones).
Sure AI (Artificial Intelligence) is cool, it will serve us humans until would finally destroy us and take over the world; but in its present state, it is only mildly amusing.
AI for audio speakers right now is basically a voice-based search engine, only as intelligent as the internet it farms information out of and yet is a far cry away from Iron Man’s Jarvis.
The naive state of AI hasn’t stopped manufacturers from putting AI into audio technology doing rudimentary commands such as play music, shopping online or even some home automation with Amazon Alexa/Google Home. However, don’t expect to have meaningful conversations with it, at the most you can play music, listen to podcasts, have ebooks read out or like a secretary/assistant, the AI can make calendar appointments, check the weather, shop online or even control the lights with home automation setup which would require additional investments of course.
Whatever may be the use, Artificial Intelligence in speaker technology is here to stay. It will only become more intelligent, more widespread and will be everywhere.
Binaural recordings are recordings that are true to how a listener would hear when a performer/band plays in front of them. So imagine yourself sitting in the centre of a room/stage with the performers performing in front and side of you. The distance, the sound loudness, the nuances of the performer/instrument all would vary as they naturally perform. Binaural recording is achieved by two microphones placed in a dummy’s head with human-like ears to record the entire performance.
This is in direct contrast to modern day recordings which are done separately for each instrument/performer, which equals to flat even sound and distance, but leads to greater control of post-recording where effects, corrections and enhancements can be made as required.
This is actually not a new recording style, it was initially experimented way back in the 1960s by Sony and Aiwa (remember the old Aiwa TV ads?) and only now has been coming into the public eye with the improved recording techniques such as Neumann KU100 microphone used to record binaural sound.
Watch a lovely song recorded with Binaural equipment. Please use earphones/headphones to hear this.
3D Audio isn’t a new buzzword, audio tech companies have always been using it for representing various things. However, the form of 3D audio has changed/evolved. You hear a lot more 3D in new forms such as VR headsets, modern day games, simulations with big giants getting into with YouTube VR and Facebook 360. True 3D audio is certainly here to stay, expect only improved renditions and newer forms to take it forward.
In fact, Sennheiser has introduced the world’s first 3D audio headset that can capture 3D sound when taking a video with special microphones attached to each earpiece. This is the first time, an earphone with two mics can record 3D audio without expensive equipment involved. The earphones are called Ambeo Smart headset and were used to make a very interesting thriller short film called Final Stop (wear ear/headphones to listen).
