Delta Expose
Extreme high resolution dynamics analyser plugin
Features
- Very high resolution analyser exposing exactly what dynamic differences are occurring
- Resolution can be magnified all the way up to two audio samples per pixel
- Trigger mode, with adjustable threshold, allows the inspection of compressor gain reduction curves
- Works with any test signal, of any kind, at any frequency, at any sample rate, with any plugin or hardware device, even using music as the test signal
- Highly accurate time markers in milliseconds, instantly updated with a fully resizable plugin window
- Gives clues and insights into propriety or unknown DSP, useful for plugin developers, audio engineers, servicing and designing hardware compressors, university students studying compression etc...
Compatibility & download
Unlike other AP Mastering plugins, Delta Expose has complex routing requirements which many DAWs cannot handle. This is why the only officially supported DAW for this plugin is REAPER. That said, it is known to work in several other DAWs. Bitwig for example lacks the proper routing capabilities but despite that, some people have gotten it to work in Bitwig anyway. But it is unlikely you will have success with Ableton. This is why it is essential that you install and open the plugin before purchase to make sure it is compatible with your computer and the DAW you intend to use it with. It is rock solid in REAPER on all operating systems.

More details
Delta Expose started life as CompView, a basic plugin originally created for a YouTube series on compression. CompView demonstrated how different types of compression could be mimicked with a sufficiently flexible compressor. Though initially a quick demonstration, thousands of people downloaded it and there was significant interest in its insights.
However, CompView had a major limitation: it relied on a high-frequency test tone to analyze gain reduction. While this method is common among analyser plugins, it introduces significant drawbacks. The test tone must be high-pitched to provide a clear plot, but compressors often apply frequency-dependent gain reduction. This means that what appears to match at 12kHz may behave entirely differently at 1kHz or 500Hz, leading to misleading results.
Delta Expose was created to solve this problem. Unlike CompView and some commercially available analysers which work on a similar principle, Delta Expose works on an entirely different principle: it directly compares gain differences between input and processed signals on a sample-for-sample basis. No special test tones, no frequency limitations—just a vastly improved resolution at any frequency, any sample rate, and at extreme zoom levels. Even at 44.1kHz, Delta Expose delivers unmatched clarity in visualizing compression curves.
Send an original signal into the sidechain, a processed signal into the main input, and Delta Expose will reveal exactly how gain changes over time. Whether you are inspecting compressors, dynamic processors, or any gain-based effect, Delta Expose provides an actual direct visualization of gain reduction with absurdly high resolution—down to two samples per pixel.
Delta Expose is probably the most revealing analyser available for visualizing the gain relationship between an original and processed signal. And plus, it looks cool.
