Sound delay in Sky music performance that occurs when using Bluetooth or streaming with a mirroring feature

I would like to inform you about the quest for the season of overlapping tones, especially since the difficulty level will be exploding,

Delay with Bluetooth

The sound through Bluetooth or other wireless earphones or headphones reaches your ears “slightly delayed”, so even if you press a note at tempo, it will be treated as slightly delayed on the screen, i.e., in the game's judgment.

The patch note says that the accuracy judging of the score has been made gentler since this season's update, and perhaps this is to account for this delay.

However, I think completing quests and musical comfort are two different things.
So, for it more pleasant for everyone to play, I prefer that

to play with speakers

or

to play with “wired” earphones/headphones

Then, you will have no delay!

Delay in Streaming

Also, when you do streaming via a computer from mobile devices, the sound will be delayed considerably when the data is imported into the computer.
In some cases, it may be at a level that makes the performance a bit unacceptable.
In such cases, I recommend that

Directly from mobile
　(This is possible with Mirativity, Tweak, Twitch, etc.)

or

Use distribution software from Steam, or Mac (with Apple Silicone)

or

Direct distribution from PS
　(YouTube is also possible. Performance is not screen tap)

or

Get sound from the original device (not from the millored one)

Then, you won't have a delay!

So, in the case of me using a cell phone, I try to use twitch, which allows me to stream directly from my cell phone via an app, instead of using YouTube via a PC for ensemble-related streaming.
I haven't mastered the PS controller yet, so I haven't been able to use it for performance yet.

But, of course, you can play with BT or streaming through OBS on the computer, etc,  I did before by predicting the amount of delay and pressing that much faster, but it requires a very "unique" skill set.

If that's what you enjoy doing, fine... but I wouldn't recommend it.

About the delay (lag) in an ensemble of sheet music

The lag (delay) in the ensemble is a different world... even taking the above into account, there's nothing you can do about it - it's all about charm, love, love.

Enjoy it and you will win...

I was an old man who thought that.

As for the lag in this ensemble, it has been dramatically reduced since the old days.

In fact, the lag in this ensemble has been greatly reduced since the old days. I can see through the tearful trial and error and effort of the people in charge of sound.

I know it must be extremely difficult.
I really appreciate it.

Hope you enjoy Season of Duet!
