Project description:
"need a VST3-format spectrum-analyzer effect that I can drop onto my mastering chain. The analyser should present a clear, precise bar-graph read-out across the audible range so I can make fast, informed EQ decisions while I work. The visualisation must be identical to the spectrum analyzer section of Logic Pro’s Multimeter plugin—excluding all other features like phase correlation or stereo balance. This is essential because no current spectrum analyzer on the market replicates that exact visual behaviour, especially when working outside Logic Pro.

Core requirements
• VST3 effect, not instrument or MIDI.
• Optimised for audio-mastering workflows (low latency, sample-accurate metering).
• Bar-graph visualisation with smooth peak-hold and adjustable decay.

I am comfortable loading standard VST3 builds in current versions of Cubase, Reaper and Studio One, so please target those hosts for testing. If you normally work with JUCE or the Steinberg VST3 SDK, that is perfect—just keep the final binary stable and signed.

Deliverables
1. Compiled 64-bit VST3 plugin (macOS & Windows, or at minimum Windows).
2. Complete source code with build instructions (CMake or IDE project).
3. Brief user guide covering controls, scale options and typical mastering-level headroom settings.

Once the plugin installs cleanly, displays the bar graph accurately, and reports true peak values within ±0.1 dB against a reference file, the project is complete." (client-provided description)
