Releases · stuerp/foo_vis_spectrum_analyzer

New: Radial Bar visualization.
Improved: Smoothing factor can be specified with 2 decimals. (Forum request)
Improved: The spectrum bars can be horizontally aligned in the graph area. (Forum request)
Fixed: Rounding errors when calculating the gauge metrics with non-default DPI settings.
Fixed: Gauge scale lines were too short (Regression).
Fixed: Slow spectrum rendering with DSD streams.
Builds with foobar2000 SDK 2024-08-07.

New: Left/Right and Mid/Side level meter.
- The left/right channel pair is selectable.
Spectogram
- New: Vertical scrolling and static spectogram. A special setting is available to align the spectogram with a spectrum bars visualization over or under the spectogram.
- Improved: Overall polishing and removal of glitches.
Added: Separate peak and RMS level read outs to the peak meter.
Fixed: An old color bug in the owner-drawn menu list.

v0.7.6.2, 2024-04-17

Peak Meter
- Changed: Removed the 1/sqrt(2) correction from the RMS reading after a long discussion on the forum.

Peak Meter
- Fixed: The RMS text reading did not appear if the corresponding X-axis was disabled.
- Fixed: Work-around for disappearing LED bars (Odd behaviour of FillOpacityMask())

Peak Meter
- Changed: Removed the 3.01 dB from the peak value.
- Added: Option to allow the user to get readings compliant with IEC 61606:1997 / AES17-1998 standard (RMS +3).
- Changed: Tweaked the coordinate calculations a bit to produce a more polished result.
Improved: The context menu will put a checkmark next to the last selected preset.

Peak Meter
- Changed: Removed the 3.01 dB from the peak value in a further attempt to make it comply with IEC 61606:1997 / AES17-1998 standard (RMS +3).
- Changed: Tweaked the coordinate calculations a bit to produce a more polished result.

Peak Meter
- Changed: Swiched the unit from dB to dBFS.
- Fixed: Some channel configurations (e.g. with side channels) were not displayed correctly.

Improved: Peak Meter
- Added style to display the peak and RMS values larger than 0dB.
- Added style to display the top peak value.
- RMS Window is now configurable. Defaults to 300ms. This makes the RMS value more stable. The RMS is relative to 0 dBFS + 3.01 dB.
- The level values were not calculated correctly when the selected channels did not correspond to the channel configuration of the track.
Fixed: Overlap of the X-axis labels (Regression)

Improved: Peak Meter
- Calibrated the peak meter according to the IEC 61606:1997 / AES17-1998 standard (RMS +3).
- Added style to display the RMS value as text.
- Reduced jitter.
Improved: Increased the maximum amplitude to +6dB.
Improved: Optimized rendering the axes a little bit and tries to preserve the more imported labels.
Improved: Artwork fit mode can use the full component window instead of just the client area of the graph.
Fixed: Setting the LED size and LED gap both to zero caused the component to freeze.
Fixed: Artwork fit mode "Fill" was implemented backwards.

Fixed: Peak Meter axes now behave as intended.
Fixed: Sample rate initialization and Nyquist frequency marker display when the component is used in a popup window.
Fixed: Disappearing artwork when the component is used in a popup window.
