Trim bird audio automatically
Chirper takes long bird recordings and automatically turns them into individual clips, organized by species.
Import audio directly from Merlin
Import an audio file or bring in a recording from Merlin. No converting files or moving everything to a desktop editor first.
Automatically trim bird recordings
Chirper listens through the recording, finds bird sounds, and trims them into individual clips. Each clip is grouped by species with a predicted ID and confidence score.
Adjust each clip
Listen to each detection, remove the ones you don't want, or adjust the start and end points if the trim is a little off.
Export by species
Export individual clips grouped by species, ready to save, share, or use somewhere else.
Normalized audio ready for eBird
Chirper normalizes the audio when you export, so clips are ready to upload to eBird without editing them again.
