Create a sine wave audio tone - Linux

[Fred vS]

In that regards I myself am intrigued by Fred vS' example as that uses fphttpclient, which removes the requirement to use libcurl (just as using a native mp3 decoder would remove the need to depend on libmpg123).

It uses also libmpg123 but with dynamic loading: https://github.com/fredvs/uos/blob/main/src/uos_mpg123.pas .
And to connect to url, it uses, done by Magic Andrew Haines, https://github.com/fredvs/uos/blob/main/src/uos_httpgetthread.pas, using fphttpclient and to connect https: openssl and opensslsockets via InitSSLInterface.
