Mel spectrograms for 2183 seconds of dog barks from 7 pet dogs extracted from 455 hours of audio recording

A bespoke corpus containing over 454 hours of audio from seven pet dogs. Data was captured non-intrusively via collar-attached miniature voice-activated recorders (e.g., STTWUNAKE, DizerLin) as single-channel (mono) audio at 16 kHz with 16-bit depth. Across all subjects, the cumulative duration of identified bark events was 2183 seconds, accounting for only 0.133% of total recording time and this is what is included in this dataset, just the mel spectrograms of the barking instances and these are Pandas DataFrames stored in Pickle file per dog.Dog NameRecording Length(hh:mm:ss)Bark Length(s)Bark/Recording Ratio(%)Bear16:42:3320.025Bertie8:10:50110.336Connie37:23:5160.108Lexi248:36:467160.080Mary29:36:108530.800Rosie65:18:553110.132Woody49:05:05440.025Total454:54:1021830.133
