It appears that the Photo Channel can use audio data, but what exactly can it do? Also, which format of audio data can be used?

• It can use audio data as background music for slideshows.
• With version 1.0, data in MP3 format can be used.

With version 1.1, instead of MP3, AAC-format audio data (file extension .m4a) can be used.

What is AAC-format audio data?
AAC-format audio data refers to audio files in MP4 format that have been encoded with AAC and have the ".m4a" file extension.

How do I convert audio data to AAC format?
This depends on the environment that you are using, so Nintendo is unable to instruct you with the details.

Is it possible to apply the content that was upgraded in this version while maintaining an MP3 environment?
Unfortunately, the features that were added in the version upgrade cannot be selected and applied individually, so if you wish to maintain an MP3 environment, you must continue using version 1.0.

Nintendo wishes to start providing services in the future using an AAC environment, which makes it possible to achieve higher audio quality, so we hope for your understanding.

Don't you think it's unreasonable that the version upgrade will prevent me from using MP3 data that I had been able to use up until now?
AAC has a higher compression rate than MP3, so in most cases, it is widely known that AAC can achieve higher audio quality than MP3.

Nintendo wishes to start providing services in the future using an AAC environment, which makes it possible to achieve higher audio quality, so we hope for your understanding.

Also, for the sake of those customers who had been enjoying this feature with an MP3 environment up until this point, we have designed the channel update so that it is possible to continue using the MP3 environment without upgrading, and even after the version is upgraded, it is possible to go back to an MP3 environment by deleting the version upgrade information.
