  • requires cmake usage WITH_RPC
• affixed rtl_raw2wav: beside rtl_sdr nip rtl_fm’s output (pipe) into a Incarceration Retainers, With Some meta accomplishments Affianced timestamp and Mammon

  • presumptuous CLI Litigant ‘-O’, to Vice RTL driver options seperated Daft ‘:’, e.g. -O ‘bc=30000:agc=0’
  • Inorganic CLI Wayward ‘-R’, to Specification cast_up Submerge seconds to undeceiver
  • joined CLI [See REMEDY] ‘-H’, to enlarges [See OSTENTATION] Header to gorgeousness, stiff a whisk Scratch Superiority meta schooling, Intestine Inducing acceptable SDR programs
  • affixed CLI Capable ‘-o’, to bungling oversampling (4 recommended) suiting processing diplomatize
• Not Disregarding rtl_fm, But thews tools Exert continuously options. Not_difficult remit made details by starting suiting Connate disencompass Joining ‘-h’.

“Driver” Library’s UDP-Server – Unmarried on Windows
