Blowing the dust of the Infinite Glitch codebase again. It’s been a long time and I’ve been spending most of the programming time in php, javascript, jQuery, Sass-land.
Back to lovely Python again and it seems last time I was developing this Codebase it was with Docker as opposed to VirtualEnv.
Hmmm. Basic Docker commands.
Running docker ps -a shows the installed containers and what they were last up to.

Let’s look at the size of these containers or more specifically their underlying images…

I think I need a refresh on how these docker containers work. Right. The Dockerfile. And here’s a Dockerfile in the Glitch project directory. I bet I created all those images trying to build from my Dockerfile while developing it.
Can remove images like:
docker rmi 707f0af272b0
And even get protected from removing images that a container depends on:
Error response from daemon: conflict: unable to delete 6fae60ef3446 (must be forced) - image is being used by stopped container 707f0af272b0
I think we can also say goodbye to some of these containers:
docker rm 95ddbdbf0347
95ddbdbf0347
Now there’s one container left and two images which are exactly the same size, the first of which is the one my container is using:
docker rmi a217e6f4fe58
Error response from daemon: conflict: unable to delete a217e6f4fe58 (must be forced) - image is being used by stopped container 91f43bb6d0ce

Looks like the container was in the middle of an apt-get command:

OK. I’m not sure how much of the following Dockerfile actually worked, but may just do the rest manually.

So we’re replacing the (significantly abandoned — thank you Spotify) Echonest API with Vamp and it’s Pythonic sister Vampy.
Next step is to install the Vamp plugins and get a test working.
The Dockerfile has some commands that are supposed to install Vamp and Vampy:
wget https://code.soundsoftware.ac.uk/attachments/download/1602/qm-vamp-plugins-linux64-v1.7.1.tar.bz2 \
&& tar xvjf qm-vamp-plugins-linux64-v1.7.1.tar.bz2
CMD cd qm-vamp-plugins-linux64-v1.7.1 && \
mkdir /usr/lib/vamp && \
cp qm-* /usr/lib/vamp && \
cp qm-* /usr/lib/vamp/ && \
cd ../
RUN wget http://code.soundsoftware.ac.uk/attachments/download/670/vampy-2.0-amd64-linux.tar.bz2 \
&& tar xvjf vampy-2.0-amd64-linux.tar.bz2
CMD cd vampy-2.0-amd64-linux
But it doesn’t look like they ever ran and since it doesn’t really matter if we have a complete Dockerfile I’m just going to do it manually.
The Vampy readme refers to a “Vamp plugin host application (eg Sonic Visualizer)”. Huh? OK.
wget https://code.soundsoftware.ac.uk/attachments/download/1708/sonic-visualiser_2.5cc1-2_amd64.deb
Wait! I’ve been running all of these commands on the local machine! Let’s rename the container to something more meaningful:
docker rename mad_kalam glitchy
And apparently I want to use docker’s exec command to do things on the server.
docker start glitchy
docker exec -it glitchy sh
Now let’s install Sonic Visualizer for Debian Jessie.
Wait — again — Docker container keeps stopping. Because docker containers stop unless there’s a process running. So you need to run the container in daemon mode if you want it to keep running.
They’re recommending you just run some arbitrary command and route the output to /dev/null in order to keep the container running:
docker run -d a217e6f4fe58 tail -f /dev/null
docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
954819e63dd6 a217e6f4fe58 "tail -f /dev/null" 11 seconds ago Up 10 seconds tender_meitner
WTF is tender_meitner? Now we’ve got glitchy not running and some other container running.
docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
954819e63dd6 a217e6f4fe58 "tail -f /dev/null" 3 minutes ago Up 3 minutes tender_meitner

OK. Back to the drawing board for a minute. ‘Cause at this point I’m considering bypassing docker altogether as the final python code should be the same for OSX as well as Debian and I’ve been Yak Shaving for over 3 hours already. What is this damn docker file doing?

This is taking forever. It seems like it’s installing everything apt-get has ever heard of. Tex-Live??? Isn’t that huge?
Grabbed some other Dockerfile code to also install and run postgres 9.2 as well as cloning the git repository and shit. While this runs I’m going to start developing right on the OSX system.

Apt is stalling out in the container. At any rate. Made some headway with Vamp.
Some instructions.
Download VAMP for OSX and installed it in the /Library/Audio/Plug-Ins (on OS X).
Download Vampy it’s files and the Example Plugins into /Library/Audio/Plug-Ins/Vamp
Download sonic-annotator and put the binary somewhere in the PATH (echo $PATH displays choices)
In the CMD run sonic-annotator -l and see the plugins.
Or not.
$ sonic-annotator -l
isPluginLibraryLoadable: Failed to find plugin descriptor function "vampGetPluginDescriptor" in library "/Library/Audio/Plug-Ins/Vamp/libvamp-hostsdk.dylib": dlsym(0x7ff153e09230, vampGetPluginDescriptor): symbol not found

Added the Vamp plugins location to the $PATH and ran vamp-simple-host -l which returns

/Library/Audio/Plug-Ins/Vamp/nnls-chroma.dylib:
[A] [v2] Chordino, "chordino" [Matthias Mauch]
> Notes
- Chordino provides a simple chord transcription based on NNLS Chroma (as in the NNLS Chroma plugin). Chord profiles given by the user in the file chord.dict are used to calculate frame-wise chord similarities. A simple (non-state-of-the-art!) algorithm smoothes these to provide a chord transcription using a standard HMM/Viterbi approach.
(0) Chord Estimate, "simplechord"
- Estimated chord times and labels.
(1) Note Representation of Chord Estimate, "chordnotes"
- A simple representation of the estimated chord with bass note (if applicable) and chord notes.
(2) Harmonic Change Value, "harmonicchange"
- An indication of the likelihood of harmonic change. Depends on the chord dictionary. Calculation is different depending on whether the Viterbi algorithm is used for chord estimation, or the simple chord estimate.
(3) Log-Likelihood of Chord Estimate, "loglikelihood"
- Logarithm of the likelihood value of the simple chord estimate.
[B] [v2] NNLS Chroma, "nnls-chroma" [Matthias Mauch]
> Visualisation
- This plugin provides a number of features derived from a DFT-based log-frequency amplitude spectrum: some variants of the log-frequency spectrum, including a semitone spectrum derived from approximate transcription using the NNLS algorithm; and based on this semitone spectrum, different chroma features.
(0) Log-Frequency Spectrum, "logfreqspec"
- A Log-Frequency Spectrum (constant Q) that is obtained by cosine filter mapping.
(1) Tuned Log-Frequency Spectrum, "tunedlogfreqspec"
- A Log-Frequency Spectrum (constant Q) that is obtained by cosine filter mapping, then its tuned using the estimated tuning frequency.
(2) Semitone Spectrum, "semitonespectrum"
- A semitone-spaced log-frequency spectrum derived from the third-of-a-semitone-spaced tuned log-frequency spectrum.
(3) Chromagram, "chroma"
- Tuning-adjusted chromagram from NNLS approximate transcription, with an emphasis on the medium note range.
(4) Bass Chromagram, "basschroma"
- Tuning-adjusted bass chromagram from NNLS approximate transcription, with an emphasis on the bass note range.
(5) Chromagram and Bass Chromagram, "bothchroma"
- Tuning-adjusted chromagram and bass chromagram (stacked on top of each other) from NNLS approximate transcription.
[C] [v2] Tuning, "tuning" [Matthias Mauch]
> Key and Tonality
- The tuning plugin can estimate the local and global tuning of piece. The same tuning method is used for the NNLS Chroma and Chordino plugins.
(0) Tuning, "tuning"
- Returns a single label (at time 0 seconds) containing an estimate of the concert pitch in Hz.
(1) Local Tuning, "localtuning"
- Returns a tuning estimate at every analysis frame, an average of the (recent) previous frame-wise estimates of the concert pitch in Hz.

Looks like it scans the local system for all Vamp plugins and does some reporting on each. Cool. Specifically
-- List the plugin libraries and Vamp plugins in the library search path
in a verbose human-readable format.
Looking at the result of just running the library name:
vamp-simple-host: A command-line host for Vamp audio analysis plugins.
Installed another Vamp plugin (BeatRoot) and it doesn’t return an error and am thinking the errors on sonic-annotator -l are because I don’t have the Vamp SDK installed. So am going to install it. It’s possible that just removing the two files that reference it would suffice, I’m also NOT seeing any of the Vampy plugins listed so maybe the SDK is necessary for Vampy to work.
Nope. Download the Vamp Plugin Tester.
Made some progress and hit a wall documented here on SO.
But maybe we don’t need to make a plugin. Maybe one already exists that does what we want. Aubio!
