ESig

A fast signal display tool written in rust and egui, which automatically downsamples and can open large signal files (>200MB).

ESig supports the following file types:

• .cf32 - Complex 32-bit floating point samples (GNU Radio, osmocom_fft)
• .f32 - Real 32-bit floating point samples

If an unknown file extension is loaded, ESig will default to *.f32.
