A web interface for annotating audio data.

audio-annotation is a web application that allows users to annotatate audio files. It is developed using Python (Flask), Javascript, HTML5/CSS3, and Postgresql. It is extended from audio-annotator. The annotation progress is splitted into two major steps: Coarse-grained and Fine-grained. In Coarse-grained, the annotator should only indicate the presence of a desired label. The audio files that have the label, will be moved to Fine-grained annotation for a deaper labeling potentially with different passes for one or more passes.

1. Admin page to view and manage tables.
2. Definable labels and annotation passes
3. Can measure annotator agreements by letting each segment be annotated with more than one person

WORK_PATH= is the starting directory. ORIGINAL_FILES_DIRECTORY= is the audio file directory (in this directory the folders should be named based on the participant and their audio recordings are located inside them) SEGMENT_FILES_DIRECTORY= After removing silence intervals and performing segmentation, the audio segments will be automatically created here.

1. Download postgresql.
2. createdb databasename
