Hi, when running the NFXLMS in Tympan Rev E we run into this continuous message:
AudioFeedbackCancelNFXLMS_F32: falling behind?
Could you please point to what might be causing this.
Is this just a warning or indicating that the AFC unable to cancel the current block.
Please let know, Thank you.
Anand
Hi!
It is just a warning that something unexpected might be occurring. Most often, though, nothing is wrong.
The warning message that you receive should also show some additional text that include some block id numbers. Sometimes that’s helpful for understanding what is happening, especially if the message keeps repeating.
If you’re just getting the message once or twice (especially if it’s at startup), there’s probably no problem.
If you’re getting the message repeatedly during operation, that’s when I would be concerned that something isn’t right.
Let me know!

Hi Chip,
Thank you so much for the response.
In our case, if the message shows up it is always present.
And it’s pretty much always 2 (the gap between block ids)
And happens every update call in certain configs.
Is there any additional information I can capture to look into this. Please let me know. Thank you.
Anand
Hi Anand, always 3, eh? I’ll have to think about that. I might not reply until tomorrow.
Is the repeated warning message interfering with your work? If so, you can suppress the message, but you’ll have to comment out the print() line in the Tympan_Library. If you’re uncomfortable doing that on your own, let me know and I can provide some directions.

Oh, and presumably your Tympan code is using the device in stereo?
Is your code on GitHub or anywhere so that I could look at the AudioConnection portion of your code?
