[Ken Fujimoto's Digital Audio LABORATORY] What is the high-resolution 3D audio playback app "Ω Player"!? Try WOWOW Distribution Experiment -Av Watch

What is "ω player" for high -resolution and 3D audio playback?

I knew the existence of the ω player when I performed an Interbee 2021 special performance.

In the session "Immersive Audio's Current Status and Future Trends", which has been distributed until December 17, introduces the WOWOW Executive Creator's Hero -Mero Hero is under development.After recording the seminar, he was called by Mr. Enrolled and asked him to demonstrate the ω player.

The demo video was a built -in speaker of Mr. MacBook Pro, but it was clearly different from the normal sound, and it sounded for the sound to jump out.

If you ask, this effect is a technology called "Auro Scene", which can be played 3D while being a stereo speaker.By implementing Auro Scene technology on ω players, the built -in speaker of the MacBook Pro produces three -dimensional expressions.

The ω player is also convenient for development, and at this time, two types of Mac and iPhone versions are available.The Mac version compatible OS is available after MOJAVE, and it can be used not only for the conventional Intel version but also on the M1 Mac.The iPhone version is for iOS 14 or later.There is a difference in the function between the Mac version and the iPhone version, specifically shown in Table 1.The introduction conditions of each Mac version and iPhone version are as shown in Table 2.

This time, we provided the Mac version app in advance, so we will use it to introduce the contents, but if you participate in the beta tester of the ω player, you can get both the Mac and the iPhone version.

Regarding this initiative, Mr. Entrance said, "I had been considering whether it was possible to distribute immersive audio for high -quality sound online for a long time. There were Dolby Digital Plus for distribution, but on the sound quality side.I was looking for a good codecs. Under such circumstances, AURO 3D can be loseless, but the file size is huge. So I hang it with MPEG-4 ALS (MPEG-4 Audio Lossless Coding).We devised the method to match three years ago and proceeded with the development. This is to be completed as an app, and it is actually a service or recruit users to conduct experiments. "
