Release Notes:

Bug Fixes:
Fixed a bug that inverts the axes upon importing data.
Fixed a bug that made the app crash when the size of the canvas size is below 1 pixel.

v1.4.0

VowSpace is an open-source desktop application developed with the aim of acquiring, visualizing, normalizing, and linguistically analyzing vowel sounds from audio files.

Release Notes:

Bug Fixes:
Fixed bug causing program crash when a cell is empty in the dataframe.
Fixed bug causing program crash when applying a qhull on 2-dimensional data.

New Features:
Added f0 (fundamental freq), f3, and f4 formants for both plotting and acquiring.
Added option to choose which formants to plot.
Added a dataframe editor to add, edit, and delete data using a UI.

Changes:
Updated dataframe methods: clear_data, read, and write.
Modified Bark and Lobanov normalization methods to include all formant frequencies.

(Previously, the program only used the f1 and f2 integers. With this update, users can now select the data they need using the UI, without needing to include unnecessary rows in their dataset. Also, if a cell in the dataset is empty for any reason, the data logic of the application simply takes it as a NaN value and won’t crash.)

Full Changelog: v1.2.0...v1.4.0
