Built Bird Audio Trimmer: Chirper

Trim bird audio automatically

Chirper takes long bird recordings and automatically turns them into individual clips, organized by species.

Import an audio file or bring in a recording from Merlin.

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.

Dial the confidence threshold up or down to hide weak detections and keep the matches you trust.

Export individual clips grouped by species, ready to save, share, or use somewhere else.

Turn your birding session into an Instagram Story with the species you found and a background of your choice.
