Are any audio formats supported in zeppos other than .opus such as .pcm or .wav?

I only see.opus mentioned in the documentation: https://docs.zepp.com/docs/reference/device-app-api/newAPI/media/?_highlight=codec#setformat

Are any other formats supported? Initial testing would lead me to believe that it isn't.

Hello @TheWiggill , thank you very much for your feedback.

We will consider supporting more audio formats, but we need to evaluate whether these formats are suitable for the usage scenarios of the watch.

Regarding these formats, could you tell us in which scenarios you use them? This will be very helpful for our evaluation. We hope you can provide us with more information.

Hi there, thanks for replying to me! I am trying to make a chromatic tuner app on ZeppOS, as this would turn the watch into a handy tool for myself and other musicians. I am currently trying to solve the problem of performing frequency analysis on the watch, and I thought that a different audio format might make that easier. That may not be the case. This is my first coding project in many years, so I'm having a hard time determining what is and isn't possible to do locally on ZeppOS. I read that .opus is compressed and thought that an uncompressed format might be easier to process. As I'm inexperienced, I might be approaching this in entirely the wrong way.

Hello, this idea is so cool. I think the watch device is very suitable for being a tuner. In fact, I'm also a music lover myself. I used to use the mobile app called Guitar Tuna.

However, I'm very sorry that currently our watches don't support real-time audio analysis (mainly frequency analysis here). We will attach great importance to this idea of yours, and perhaps this feature will be implemented in our subsequent products.

Thank you for your response! I was told that a live audio buffer isn't available, so I was hoping to perform analysis on samples recorded at short intervals. But the frequency analysis seems like a challenge that I cannot overcome for now. I look forward to future updates!

Hi, will balance2 support other audio formate like m4a, aac ...etc. Because I usually down loaded some audio pocast and most of them are m4a. I hope can upload them to my balance2. Thanks
