Linux uses PulseAudio, which has a poor default configuration, resulting in bad sound.
With some tinkering with the PulseAudio file, reading a lot of websites about the settings, I was able to get PulseAudio to have sound that’s subjectively as good as BSD, Mac, etc. By default, PulseAudio uses a resampler called “speex-float-1” which is horrendous. The reason this is chosen is to maintain compatibility on very small and bad sound cards. This shall be reconfigured to either “speex-float-10” or “soxr-vhq” for best quality. Some other changes also improve the sound.

SCP is short for secure copy protocol and is used to copy files and directories between multiple Linux machines over a network. The data transferred using SCP is encrypted to protect your data against nefarious agents.
The SCP command uses SSH for data transfer and thus uses all the same usernames and passwords you would use for SSH. As a result, it is an extremely useful command for transferring files securely without too much added complexity.
