|
* pkg-config
|
|
* qt5
|
|

|
|
* `*.cf32`, `*.cfile` - Complex 32-bit floating point samples (GNURadio, osmocom_fft)
|
|
* `*.cs16` - Complex 16-bit signed integer samples (BladeRF)
|
|
* `*.cs8` - Complex 8-bit signed integer samples (HackRF)
|
|
* `*.cu8` - Complex 8-bit unsigned integer samples (RTL-SDR)
