When getting terms for an artist, it's great to get the frequency value, in order filter out popular terms like rock, pop, etc and give greater significance to rare terms. Could you please include this when fetching top_styles from the catalog/predict endpoint? At the moment it just gives you a count.
In return, we shall build something that demonstrates to the world the power of this endpoint ;)
Thanks!
Thanks for the error messages! I am pretty sure that the first is totally my fault: there was a problem with the windows installer. My apologies, and try the latest version, here: http://static.echonest.com/remix/packages/remix-2.2.0.win32-py2.7.exe.
I am still not sure what might cause that ImportError - I will keep working on it, but it may be a Windows Server issue...
Hi Thor,
The new installer fixed the error messages I posted. However, the ImportError still occurs. I have a feeling that I need to install a C++ runtime installer on my server. I tried Microsoft Visual C++ (http://www.microsoft.com/en-ca/download/details.aspx?id=5582) but didn't have any success.
You mentioned that you set up a Windows 7 machine. Were you successfully able to run capsule.py? If so was it a bare bones version of Windows 7 or did you have Visual Studio or any C++ runtime installed?
Askash:
You need to include a request for the audio_summary bucket. Change your call to this:
s = song.Song(song_ids[i], buckets=['audio_summary']);

ryan - we didn't create neverendingplaylist.com, but they do power it with our API. The docs for the API are here:

Yes. Rdio will play full songs for subscribers and 30 second samples for non-subscribers.

what results do you want when you search for songs by Elvis?

Thanks for the suggestion.

robjellis - sorry - we haven't published the algorithm on how we derive tempo fro the IBI. -- Paul
we haven't published a time frame for this yet. Sorry. -- Paul
Ok. I finally got passed the ImportError after installing SQL Server 2012 R2 (which is powered by Visual Studio). I'm assuming the proper C++ runtime got installed during this process.
However, I did get another error when running capsule.py. Below is the error message. I hope you can help!

We apologize for the disruption.

Hello!
I am glad you got it working - though I do not fully understand how that install fixed those errors.
capsule.py doesn't need you to specify an output file. Try:
python capsule.py "c:\He Won't Go.mp3""c:\Don't You Remember.mp3" -e -v
Best, Thor
Hi Thor,
I removed the output file but the error looks to be the same:
c:Python27echo-nest-remix-examplescapsule>python capsule.py "c:He Won't Go.m p3""c:Don't You Remember.mp3" -e -v

Some more info - the temp wave file created is 0kb. This explains the EOFError. Something in LocalAudioFile() is causing this.....
No worries, Paul; just didn't want to think I'd missed something obvious!
The EchoNest Analyze documentation mentions this:
Beats are subdivisions of bars. Tatums are subdivisions of beats. That is, bars always align with a beat and ditto tatums.
Does the same hold true for alignment with segments? For example, does a bar always align with a segment?
kris-ri - no, segments are not always aligned with bars, beats or tatums. -- Paul
Bump.
I had to turn my production environment into a development environment so that I can debug what is going on. That being said, the error I am now getting is related to en-ffmpeg.exe (located in the root of C:\Python27).
"Can't determine profile of DV input stream. C:\Music\song1.mp3: Error while opening file".
The file song1.mp3 does exist in the C:Music folder. It is not encoded.
