Receive HTTP MP3 Stream from Each Song

Question

I need to get the direct url from a SoundCloud MP3 file.

I usually used the following method: Allow the URL of the track to get the track ID, for example. using https://soundcloud.com/linkin_park/burn-it-down with

http://api.soundcloud.com/resolve.json?url=http://soundcloud.com/your/link/to/the/track&client_id=client_id 

Then go to stream_urls with

http://api.sndcdn.com/i1/tracks/track_id_here/streams?client_id=client_id

In most cases, returns "http_128_mp3_url", the URL I need, which is directly related to the MP3 song.

But in some cases, for example, when you use https://soundcloud.com/dada-life/dada-life-september-2014-mix , only the rtmp or hls stream is returned, which I can not convert to a file with PHP or JavaScript .

As you can see at http://sounddrain.com/ , there is a way to get a link to an MP3 file in this case too.

Sounddrain gives me this URL:

https://ec-media.sndcdn.com/KZ5qiLqZ0OSk.128.mp3?f10880d39085a94a0418a7ef69b03d522cd6dfee9399eeb9a522029c6df9ba3f0cf21c0c0d7b8778f4d4c4f4dfcd

Does anyone know how to get the following url?

Answer 1

I think this is specifically related to the type of client_id that you pass into the API request.

 HTTP GET: http://api.soundcloud.com/i1/tracks/167132129/streams?client_id=[CLIENT_ID] 

Using the standard client_id application, I do not see the http link:

More information can be found in this commit and this problem on the youtube-dl page. I don’t know exactly what the difference is between the regular client_id and iPhone client_id, but I can clearly see the difference in what is returned by the API request. IPhone client_id seems to be the API key used by the SoundCloud iOS client to stream tracks in the app.

Answer 2

soundcloud transcodes all downloads to 128k mp3 for streaming. as long as you turn on streaming, and the track is publicly available, all you need is

https://api.soundcloud.com/tracks/TRACKID/stream?client_id=CLIENTID
