Get track analysis data for your music using the Echonest API.
The track analysis includes summary information about a track including tempo, key signature, time signature mode, danceability, loudness, liveness, speechinesss, acousticness and energy along with detailed information about the song structure (sections) beat structure (bars, beats tatums) and detailed info about timbre, pitch and loudness envelope (segment).
Its a two (or three) step process. Here’s an example of how to upload your track and get an audio summary, using curl from the command line in Mac OS. Note, you will need to register with Echonest to get a developer API key here: http://developer.echonest.com/raw_tutorials/register.html
Note that the path to the filename needs to be complete or relative to the working directory. Also, in this example there was no metadata identifying the title of the song. You may want to change this before uploading. Replace the API key with your key.
Around the year 1700, several startup ventures developed prototypes of machines with thousands of moving parts. After 30 years of engineering, competition, and refinement, the result was a device remarkably similar to the modern piano.
What are the musical instruments of the future being designed right now?
Are there patterns in the ways that artists adapt technology?
For example, the Hammond organ borrowed ideas developed for radios. Recorded music is produced with computers that were originally as business machines.
Instead of looking forward to predict future music, lets look backwards to ask,”What technology needs to happen to make musical instruments possible?” The piano relies upon a single-escapement (1710) and later a double-escapement (1821). Real time pitch shifting depends on Fourier transforms (1822) and fast computers (~1980).
Artists often find new (unintended) uses for tools. Like the printing press.
The piano is still in development. In December 2014, Eren Başbuğ composed and performed music on the Roli Seaboard – a piano keyboard made of 3 dimensional sensing foam:
Here is Keith McMillen’s QuNexus keyboard (with Polyphonic aftertouch):
Harmonic Model Plus Residual (HPR) – Build a spectrogram using STFT, then identify where there is strong correlation to a tonal harmonic structure (music). This is the harmonic model of the sound. Subtract it from the original spectrogram to get the residual (noise).
What is the speed of electricity? 70-80 ms is the best round trip latency (via fiber) from the U.S. east to west coast. If you were jamming over the internet with someone on the opposite coast it might be like being 100 ft away from them in a field. (sound travels 1100 feet/second in air).

There is a quickening of discovery: internet collaboration, open source, linux, github, r-pi, Pd, SDR.
“Robots and AI will help us create more jobs for humans — if we want them. And one of those jobs for us will be to keep inventing new jobs for the AIs and robots to take from us. We think of a new job we want, we do it for a while, then we teach robots how to do it. Then we make up something else.”
“…We invented machines to take x-rays, then we invented x-ray diagnostic technicians which farmers 200 years ago would have not believed could be a job, and now we are giving those jobs to robot AIs.”
I downloaded the fork version from ‘dewb’ as it has been converted to run in Max6. It looks like the object retrieves all of the analysis data. It would actually be instructive to read the source code to see how they implemented libcurl and JSON for the http: requests.
