what's in a meow?? 🐈
New from @berlinbatlab.bsky.social!
1. "we examined meows and purrs to establish how individual identity is encoded"
2. stronger individual signature in purrs than in meows
3. domestic cat meows more variable than those of wild felids

If you know Tunic, you know that the developers hid many secrets within the game including in the game’s music and audio. When I played it I went deep down the rabbit hole, filling a whole book with notes as I managed to decipher the game’s written language and find hidden images in spectrograms.

Hasn't Audacity always had spectrograms?

Holy shit, Audacity 4 has Spectrograms!
Spectrograms in Audacity 4 are almost complete. Gosh, we're really getting there now.

Mainly, you can now easily plot ERB and Mel scaled spectrograms and spectra. This something that I didn't know a nice way of doing before but came in handy when teaching the difference between 'physicalist' and 'perceptualist' (?) scales. Hope this can be useful to others too!

2) has a spectrogram where the most energy is clearly sitting a bit below 20 Hz with noticeable fall off at higher and lower frequences. Natural noise sources aren't confined like that.
3) spectrograms show no change in energy at all across entire time period (plus that's what noise looks like).

AI conclusion. The spectrograms confirm both audio clips capture the same class of Russian cruise missile on terminal trajectory. The Doppler descent pattern, broadband turbulence, and resonance envelope are identical. No data supports the claim of a Patriot or any other SAM.

AI audio analysis of two separate missile recordings from the Ternopil strike shows the same terminal aeroacoustic structure. Spectrograms of both clips reveal identical broadband energy bands and the same descending Doppler slope as the missile approaches impact.

Linguists, you are the best. Happy Linguistics Day, and thank you for doing all those things I would never want to do myself—like analyzing spectrograms and corpus data—but I'm glad you seem to enjoy. Because I enjoy hearing about the results.

I think so. I think also the biggest gains from increasing FFT resolution is shown at low freqs. I forgot this earlier when I told you it might be a bug. I'm not more confident that this is just an inherent trade-off with spectrograms.

Oh wow thanks. Didn’t know while using spectrograms all the time on waveforms.

Version 2: Added in Nashville and the waterthrushes.
Putting together another edition organized by spectral frequency. Several warblers are very easy to pick out when you know where they fall on the spectrogram. #birds
