Spectrum Lab Changelog

What's new in Spectrum Lab 2.94 b4

Feb 23, 2020
  • Extended CAT/CI-V protocol to display broadband spectra from an IC-7300, IC-7610, IC-7851, etc(?)
  • Forwarding of CI-V messages from and to multiple clients (e.g. WSJT-X, RS-BA1) on extra serial ports
  • Timestamped event queue for the Conditional Actions
  • Non-differential encoding for experimental (B)PSK transmissions
  • New sample formats received over the serial port (e.g. from the GPSDO currently under development)
  • Modified the reader for non-compressed, timestamped web streams (and their logfiles; *.dat)
  • Modified triggered audio recorder
  • Modified COM port enumeration because a stupid Bluetooth driver blocked the application for many seconds
  • Spectrum buffer can be retrieved as JSON object via SL's integrated web server
  • Different buffer sizes for audio processing and soundcard I/O
  • Modified Audio-I/O DLL interface (bugfix in the configuration dialog)
  • Support for RTL-SDR (via ExtIO-DLL)
  • Improved speed, at the expense of compatibility with ancient 80486
  • EbNaut-recorder configuration files
  • Compressed Ogg/Vorbis file selectable for recording audio (besides non-compressed Wave audio)

New in Spectrum Lab 2.72 (Oct 21, 2008)

  • Added support for PERSEUS (a direct sampling LF..HF receiver by Nico Palermo (IV3NMV) / Microtelecom .
  • Added the possibility to "play back" the contents of the spectrogram buffer, using an inverse FFT to convert the spectra back into audible signals .
  • Added the 'hard limiter' in the signal processing blackboxes.
