Soundcloud downloads are wav, even if mp3 is specified

For instance:

youtube-dl --audio-format mp3 https://soundcloud.com/mycelium_music/spore-session-vol-13-emog-12-3
[soundcloud] mycelium_music/spore-session-vol-13-emog-12-3: Resolving id

WARNING: Your copy of avconv is outdated and unable to properly mux separate video and audio files, youtube-dl will download single file media. Update avconv to version 10-0 or newer to fix this.
[download] Destination: Spore Session Vol. 13 - Emog [12-3-2013]-123028713.wav

I'm not sure whether this is because there isn't an mp3 available? If not, rather than downloading the wav, youtube-dl should probably suggest an alternative format. The user probably doesn't want to hammer soundcloud with a giant unecessary wav download!

youtube-dl downloads best available quality by default. You have to explicitly tell it not to download wav if you don't want it.

@dstftw if you look at the command line I used, I actually attempted to do that with the --audio-format flag, which was the first thing I found by searching for "mp3" in the man page. Why doesn't --audio-format x imply --format x for audio-only downloads?

[dstftw]

Because these are different options. --audio-format a postprocessing option that is only used with --extract-audio to specify settings of audio stream to be extracted from downloaded format (wav in this case). --format is an option to specify formats to download.
