simple textgrid to csv converter

textgrid

Version 0.2

A minimal python TextGrid module and CSV converter.

Tier labels are saved as a column called "tier". Points are treated as intervals with identical start and stop values.

Example input:

File type = "ooTextFile"
Object class = "TextGrid"

xmin = 0 
xmax = 4387.9766666666665 
tiers? <exists> 
size = 1
item []: 
    item [1]:
        class = "IntervalTier" 
        name = "Mary" 
        xmin = 0 
        xmax = 4387.9766666666665 
        intervals: size = 1
        intervals [1]:
            xmin = 0 
            xmax = 5.537098932314087 
            text = "z"
