inspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.

Currently inspectrum can only read files with interleaved (complex) 32-bit floats, such as those produced by GNURadio or osmocom_fft.
- Spectrogram with zoom/pan
- Large (multi-gigabyte) file support
- Be fast and light
- Make as many settings as possible work in realtime. I want this to be a useful tool for visually learning about DSP by tweaking around with things like FFT settings, filter widths or clock synchronisation.
- Support large files - as large as possible, but at least several GBs.
- Future features: filtering, demodulation, clock sync. Probably based on GNURadio.
