You keep claiming this. Is this an assumption of yours? Are you saying HomePod downmixes the channels to one? Do you have proof other than Apple’s vague marketing blurb?
I don’t think it’s as vague as you think, and yes it’s my assumption based on
Apple themselves saying you need 2 HomePods for stereo playback and Something else I thought up on my own just from looking at the design of the HomePod.
As we know it, the HomePod has 7 tweeters or speakers in it, going around the device in 360°.
1. If it did play sound in stereo, you would need a left and right channel. But for arguments sake, let’s say it does have a left and right channel.
2. How does it know which of the 7 speakers to use as left channel and right channel?
3. Ideally, you would want the same number of speakers on the left and right channels. This has 7 speakers.
4. Because the speaker is a 360° design how does the average consumer know where the left and right channels are?
5. Let’s assume people figure out where left and right channels are and want to sit or stand in the middle so they can hear both channels equally. There will be no sweet spot because the HomePod is 360° In design. At most 3 speakers will be facing the person in front of it.
6. How does one be in a sweet spot of a 7 speaker 2 channel system of only 3 speakers at a time is facing the person?
8. If this were stereo playback through 2 channels then multiple people around a single HomePod will not always hear the same things equally. Some songs play specific sound effects through the left and right channel.
9. Apple is able to achieve the sweet spot they claim by playing all sound through all the speakers and not splitting them into 2 channels or stereo. That’s why anywhere you stand around it sounds good.
The song “In and out of love” by Armin Van Buuren is a favorite of mine and it shows how well what stereo sound, sounds like. You can hear the effects being bounced back and forth from left to right. It’s a perfect example of stereo imaging and separation. Best heard with headphones.
