Impulse runner fails on Nano33BLEsense

with the impulse runner on Nano 33 BLE sense, I’m getting the message:

[SER] Started inferencing, press CTRL+C to stop…
Inferencing settings:
Interval: 0.01 ms.
Frame size: 284927
Sample length: 17807 ms.
No. of classes: 2
ERR: Failed to setup audio sampling

Can I somehow adjust the inferencing settings to stay within the buffer size?


@Wolf this looks like it cannot allocate a buffer for your 17.8 seconds of data (which makes sense, it’s a frame size of 284927 x 2 bytes = more than the Nano has in RAM). Best bet would be to reduce your window size in Create impulse.
