Record audio streaming with Ruby (on Rails)

问题

I need to record some radio programs and make them available for later listening.

I have looked into the Shoutcast API for getting the audio streams resources, but don't have a clue how to record an audio broadcast and save it in an audio file.

I'm looking for any Ruby libraries, or even some information on how to get started.

You can save the stream in a file, for example :

require 'net/http'
require 'uri'


url = URI.parse('http://your.stream.domain.com/')

Net::HTTP.start(url.host, url.port) do |http|       
        f = open("saved_stream.mp3", "w")
        begin
            http.request_get('/stream_path.mp3') do |resp|              
            resp.read_body do |segment|
                f.write(segment)                 
            end
            end
        ensure
            f.close()
        end     
    end
