According to Amazon, “Today we are excited to announce equalizer (EQ) and sound mode controls for smart home entertainment devices, available today for customers in the US across the Amazon Echo family of devices, and on select Alexa-enabled devices built using the Alexa Voice Service (AVS). Now customers can personalize the tone of the audio playing on their speakers, AV receivers, and sound bars by simply saying, ‘Alexa, crank up the bass,’ ‘Alexa, turn up treble,’ or ‘Alexa, set TV mode.’”
Some of Alexa’s abilities include adjusting the amount of bass, adjusting the amount of bass in specific rooms around the house, adjusting the treble levels, adjusting the equalizer on specific devices, and also swapping between various “modes” such as night mode, movie mode, and so on.
Given that different genres of music might benefit from different equalizer settings, the ability to use Alexa to change it on the fly sounds like a useful one. Of course not every speaker will be able to take advantage of this new skill, but if you own any of Amazon’s Echo speakers you should be good to go, along with third-party speakers that have Alexa baked into them.
