Abstract: In this paper we present the differentiable log-Mel spectrogram (DMEL) for audio classification. DMEL uses a Gaussian window, with a window length that can be jointly optimized with the ...

A better form of cloud storage. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Before it was used to subject us to an endless churn of ads and ...

I tested lora_TX and lora_RX with different frequencies and bandwidths. Receiving messages was mostly successful, but when I wanted to observe the chirp on gqrx spectrogram, I couldn't make it. No ...

Capital investments fund long-term assets crucial for business operations and growth. High capital investment often indicates a robust economy; low investment may signal economic concern. Investors ...

(A) Recording apparatus. Four ultrasonic microphones sampled at 125 kHz continuously recorded a family in an enlarged environment. (B) Experiment timeline. Three gerbil families with the same family ...

Song degradation and transcriptomic changes after chronic inactivation of inhibitory neurons in HVC by viral expression of tetanus toxin (TeNT). Examples of abnormally long syllable lengths after ...

The Australian EEZ provides habitat for ten species of mysticete whales seasonally supporting critical life functions ranging from feeding to breeding. All of these species produce downsweeping calls, ...

The only source of our information on stars is their radiation. From stellar spectra we judge the structure of stellar atmospheres, their chemical composition, and physical processes taking place ...

Biological sources are significant contributors to aquatic soundscapes. Soniferous fish can dominate the soundscape in certain locations, at specific times and frequencies, particularly during the ...

Signal analysis and classification is fraught with high levels of noise and perturbation. Computer-vision-based deep learning models applied to spectrograms have proven useful in the field of signal ...
