Performance Comparison

Many people familiar with BirdNET have used the "BirdNET Analyzer GUI" for automated bird call identification. Due to many optimisations made in the application, Chirpity is able to perform the analysis significantly faster. The following benchmark data show the time taken to analyse a file just over 3 hours long. Firstly using the native Chirpity detection model, then BirdNET within Chirpity, and finally BirdNET using the BirdNET Analyzer. The number in brackets shows how much faster than real-time this represents:

Model Core i5 CPU Core i5 GPU M2 CPU M2 WebGPU
Chirpity native 80s (140x) 28s (388x) 67s (167x) 44s (252x)
Chirpity BirdNET 106s (106x) 270s (41x) 75s (148x) N/A
BirdNET Analyzer 549s (20x) N/A N/A N/A
