What is iem-tool?

IEM Tool is a free, offline application built for people who are into in ear monitors, a type of earphone often used by musicians and audio enthusiasts. It brings together many separate tasks into one program, letting a user rate and review their IEMs, tune sound with a ten band equalizer, and automatically tag or compare different models, all without needing an internet connection. The app includes a review dashboard where someone can write notes and ratings on the sound characteristics of each IEM they own. It also has an equalizer section for adjusting frequencies and applying tuning presets, plus an audio test lab with tools like a blind A to B comparison test and a hearing test to check what frequencies a listener can actually perceive. A built in music visualizer shows real time graphics that react to whatever audio is playing. For personalizing the experience, the app offers several visual themes for its review cards, with names like Void, Graphite, Midnight, and Sunset, so exported score cards can match a preferred look. Settings let users adjust general preferences and appearance. Two separate helper programs come bundled alongside the main app. The IEM Manifest Generator scans a folder of measurement curve files and rebuilds a list the main app uses to know which IEMs are available in the library, which is needed whenever files are added, removed, or renamed. The IEM Curve Converter takes raw measurement data downloaded from other sources, which can come in inconsistent formats, and standardizes it into a format the main app understands, including automatically averaging separate left and right channel measurement files into one combined curve. Both helper tools are described as portable executables that do not require a separate Python installation to run, and the overall project is aimed at hobbyists who want a self contained, private tool for exploring and comparing in ear monitor sound profiles.
