i think i… meowed in my sleep this morning????

@kemona_halftau do you record yourself while you sleep? how do you find interesting stuff in the recording without listening through hours of what is probably mostly silence and nonsense?

apparently I talk in my sleep so I've thought about doing that to see what I say (and if I leak any passwords or other meaningful information), but I'm not listening to a multiple-hour-long mostly-silent recording, that'd be as boring and time-consuming as watching CCTV footage

@noisytoot i listen to my sleeptalking trimmed to audio containing frequency components between 300 and 600 hz at 4x speed throughout the day and pause when i hear something interesting
sometimes i knock the microphone onto the floor in my sleep when rolling over, so the recordings are usually unusable anyway because of that
i compress historic recordings with opus because .wav files are giant

@noisytoot another thing that gets in the way of recording my sleeptalking is my white noise machine picking up interference from a shortwave radio station around 9.46mhz (i think the noise generator acts as a form of tuned wide-band am detector circuit almost????)

@kemona_halftau does a white noise machine do anything different from aplay /dev/urandom?

@noisytoot kinda. mine has a few looping sounds on it which are meant to be “relaxing” which i assume get modulated with the output of a pseudorandom number generator (in this case incidentally a tuned radio detector) to produce a more variable signal. the presets are looping sounds such as crickets, a waterfall, birds, etc which dont get modulated, while the white noise preset does get modulated, except the white noise itself is a looped recording
the recordings are very short too, i measured the white noise one to be about 8.3 seconds
also the pitch/speed of the recording fluctuates when the voltage is low, such as when im running it off of a 3.7v li-ion battery pack (it is intended to run at 4.5v)

@kemona_halftau I keep losing my sleep earbuds so I can’t ever listen to my sleep recordings, my headphones record for sleep talking but I keep forgetting to connect them back to the app

@kemona_halftau I listen to music while falling asleep, which would definitely interfere with the recording, but I could just delay the start of the recording by a few hours (until after the music ends) to work around that
