SDR# Updated: Improved Performance and Better RTL-SDR Compatibility

SDR# (SDRSharp) is one of the most popular free software defined radio programs available with RTL-SDR support. Recently it has been updated to version 1811 and the new version brings improved performance and also improves RTL-SDR compatibility with some systems. The changelog reads:

Date:   Mon Mar 29 15:03:09 2021 +0200
Commit: d5cb6c3

More DSP optimizations;
Many fixes for RTL dongles (mainly workraounds for old libs);
Revert to libusb 1.0.20.11004 for backward compatibility;
Revert to portaudio 2016 for backward compatibility;
Code cleanup.

@lambdaprog (the SDR# programmer) has also tweeted showing how well SDR# can run on a 10 year old i7 4700 laptop with the new performance improvements. With a huge 160 MSPS baseband IQ file, the software is seen to be using very minimal CPU.

    SDR# is the greatest software ever compiled for us RTL-SDR dongle users. Thank you to all involved who made this possible. And, thank you Gary for this excellent and informative website.
