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. The test tone must be high-pitched to provide a clear plot, but compressors may 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. Delta Expose offers 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, providing an actual direct visualization of gain reduction with absurdly high resolution—down to one individual sample per pixel.
