[SR3 52 FW V1.2] OPUS migrate and ANR

[Judge]

hi ,

1. How do I migrate the codec OPUS part of SR3 ? I want to use it for audio. But migration always fails. Any migration examples?

2.How effective is ANR work? Are there any quantitative parameters for the effect? What restrictions do I have on using it?

Hi, sorry, I don't understand what you want to migrate. Migrate OPUS to where? Any error messages during migration?

The SR3 only includes a demo version of ANR which adds a beep to the signal at regular intervals. If you want to get the full version contact vocal.com, maybe they have some numbers on the efficiency as well

hi Stian，

Can you provide a simple demo that has already migrated the OPUS codec?

Compilation has a lot of errors, and I can't fix them.

Hi 

Sorry for the delayed response. Stian is currently unavailable, and I will help out in the mean time. 

Are you still having issues with this?
Migrating the OPUS codec from the nRF52832 to the nRF52840 should be relatively straight forward, since the nRF52840 is basically just a more full featured version of the nRF52832 with additional memory and peripherals. 

If you are still having problems I will try to provide an example for the nRF52840. 

Best regards

hi Torbjørn，

I tested OPUS algorithm performance use SR3 v1.2. DK10040. PCA63519.

I want to test the performance of silk mode.I used the following configuration, but found it didn't work properly and I couldn't see its CPU consumption.I want to know something about the use of silk mode.

And do you have a migration of a simple project that includes the OPUS algorithm?

hi Torbjørn，

I still having issues with this.If you can provide a 52840 that contains the OPUS codec, that's great !

Hi Judge

Please find a small example attached. It's an un-official example made by one of our software guys, and is provided "as is". In other words, use it at your own risk ;)

hi Torbjørn，

Thank you very much for your reply.

This is a GCC project.Do you have the code use keil or segger or IAR ?

Hi Judge

No, this example was made for GCC only unfortunately.
