There is plenty of information around here for you to start.
Instead of coming here for pre-cooked recipes, you should show you at least
tried...

You could read the
http://nginx.org/en/docs/http/ngx_http_rewrite_module.html docs
<http://nginx.org/en/docs/http/ngx_http_rewrite_module.html#return> or some
tutorials from quality sources
https://www.nginx.com/blog/creating-nginx-rewrite-rules/.

Since I am in a good mood, Apache redirect rule #2 *might* (note emphasis)
transform into this:
location ~* ^/s/(?<source>.*)$ {
return 301 /audio_redirect_source.php?u=$source;
}

​Why are you providing backend code again?​ It really feels like 'I do not
understand how the whole thing works and/or I have not thought about that
stuff at all, please do it for me'.
