I recently noticed that some observations (e.g. Observation 5839141) from my station are marked ‘failed’ even though the observation contains a waterfall and the sound recording. Is it a bug?
I’m not sure how it got marked, but to me that one looks like
it should be marked “Bad” not “Failed”.
This happens automatically when the audio duration is at least 1 minute different from the scheduled duration. In the linked observation the scheduled duration is 4min 58s and the audio is 3min 28s.
This difference usually happens when there are lost samples, samples that the cpu can not handle. The reason behind that tends to be a high sample rate or high cpu temperature that force cpu to run in lower frequency and lose samples or not good power supply which has the same effect as the high temperature on cpu.
