openmeters 1.18.0

What Changed?

New Features

• LUFS-I and LRA are now available within the loudness meter. Double click the visual to reset the measurement.
• Configuration hot-reloading is now supported. Config/theme file edits are immediately reflected within the running session.

Fixes

• Lots of minor bug fixes, a panic with ASan caused by pipewire-rs.

openmeters 1.17.0

What Changed?

Many new features, UI changes, optimizations, and bug fixes:

• Visual configuration pages now sort some controls via collapsible cards. Click to expand or contract them.
• The color picker for all palette stops has been redesigned to be more user-friendly. Hex values can be copied and pasted directly from within the UI.
• The oscilloscope now spans the full window height to match the waveform.
• The oscilloscope's fill is now a fade, which improves readability in stacked mode and in general looks more aesthetically pleasing.
• The spectrum analyzer's range is now equivalent to the spectrogram's.
• The spectrum may now also be rotated in all unique directions, same as the spectrogram.
• Spectrogram rendering was redesigned, reducing work approximately five-fold in all cases.
• Block driven events were replaced with audio driven events for consistency across frame rates (see below).

What Broke?

Because block-driven values were replaced and naming needed to be updated, oscilloscope persistence will fail to load. If you use it, set a value again within the GUI.

openmeters 1.15.1

What Changed?

• Fixes for the loudness meter were the main focus this time around.
• Rear weighting is now distinguished from side weighting, tests were expanded and refined.
• True-Peak accuracy has been greatly improved, see the body of 797be8a for more details and a brief comparison against other implementations.

openmeters 1.14.0

What Changed?

This is another minor release consisting primarily of numerical improvements. Monitor selection and fallback behavior was improved, as noted in #24. Spectrum labels now displace grid lines where they overlap, which improves readability. Other internal improvements have taken place as well. Thank you for sticking around, and for 200 stars on GitHub!
