Best Spectrum Analyzer Plugins 2024

By segmenting the frequency spectrum to represent the range of frequencies, spectrum analyzers are tools that give the user detailed information about the sounds during music production. The frequencies are represented by the horizontal (x) axis, while their amplitudes are represented by the vertical (y) axis. The frequency range that can be heard by the human ear is typically from 20Hz to 20kHz, which is the range that is displayed on a spectrum analyzer.

iZotope Insight 2

iZotope Insight 2 is a comprehensive metering and audio analysis plugin that is widely used in post-production and music studios. It offers a detailed and responsive spectrogram for monitoring the complete spectral content of your mix. It provides a clear and intuitive display, allowing music producers to visually monitor their work. The user interface is customizable and resizable, fitting any professional audio mixing and production workflow. The plugin’s design is easy on the eye, making it comfortable for extended use.

Insight 2 includes a variety of metering tools such as true peak, RMS, and K-system level meters, loudness meters, 2D and 3D spectrogram, spectrum analyzer, and both a stereo vectorscope and surround scope. It also includes a unique Intelligibility Meter that measures the clarity of dialogue in the mix, providing visual feedback on whether the dialogue is being overshadowed by the rest of the mix. This feature can be particularly useful in post-production work where dialogue clarity is crucial. The plugin also includes Relay, a feature that routes any specified tracks or buses to Insight 2 for analysis. This allows for a clear picture of how individual tracks stack up against the entire mix.

Insight 2 includes tools to analyze stereo imaging and mono compatibility. It provides variations on the vectorscope theme to analyze stereo imaging. Good mono compatibility is assured if the dots lie mainly within a ±45-degree angle from the center. It is also noted for its ability to help meet streaming standards of audio equipment, such as Netflix’s dialogue spec or YouTube’s compression thresholds to tailor the experience.

iZotope Insight 2 is a comprehensive and versatile audio analysis tool that offers detailed visual feedback and a range of features to assist in audio mixing and production. Its Intelligibility Meter and Relay features, in particular, set it apart from other metering plugins. However, some users have noted that the plugin could be intimidating for those unfamiliar with audio analysis tools, despite iZotope’s efforts to keep the interface as simple and friendly as possible.

This is the Best Spectrum Analyzer VST Plugin in 2024.
