Marsyas - Music Analysis, Retrieval and Synthesis for Audio Signals

Trailing whitespace are a real issue in this project. Nearly every file contains trailing whitespace, which make it almost impossible to use git add -p or just view a diff if your editor is configured to strip whitespace automatically.

This project should follow the example of the the Linux code guidelines and everybody working on this project should use an editor which strips trailing whitespaces to reduce noise in git and possibly other CVS in the future.

As discussed in #3 marsyas needs a global style guide.

The outcome of #3 so far is to use two spaces indentation and the Google C++ guidelines but with the block beginning on the same line as the statement (if(...) {).

This should definitely be summarized in a document (README?) on the root of this project.

Hello,

I'm trying to compile Marsyas for Xcode and demo applications and I am finding errors in different situations. If I compile manually everything is fine, so I expect that there is something wrong with the configuration.

If I configure cmake with Marsyas_Static flag DISABLED, I get linker mach-o (ld) errors, and libtool finds problems with some of the flags (-dynamic, -Wl,-headerpad_max_install_names), and Marsyas lib is only compiled by removing those flags

If I configure cmake with Marsyas_Static flag ENABLED, I compile without errors.

However, none of the examples gets compiled for any of both configurations. Has someone identified this problem yet?

Thank you, FB

I resampled a 440Hz sinusoidal wave to 11025, 22050, 36000, 44100, 46000, and 48000Hz respectively. The system connection is simply SoundFileSource ==> AudioSink || SoundFileSink. When I connect to AudioSink, the playback speed is wrong except for 44100Hz and 48000Hz: 22050Hz gets 2x faster, 11025Hz gets 4x faster, 36000Hz gets faster and 46000Hz gets slower. However, if I connect to SoundFileSink the output wave files are all correct.

Here is the code. I comment out the lines of SoundFileSink.

#include <marsyas/system/MarSystemManager.h>

using namespace std;
using namespace Marsyas;

void sfplay (string sfName) {
  MarSystemManager mng;

  MarSystem* playbacknet = mng.create("Series", "playbacknet");

  playbacknet->addMarSystem(mng.create("SoundFileSource", "src"));
  playbacknet->addMarSystem(mng.create("AudioSink", "dest"));
  //playbacknet->addMarSystem(mng.create("SoundFileSink", "dest"));

  playbacknet->updctrl("SoundFileSource/src/mrs_string/filename", sfName);
  playbacknet->updctrl("AudioSink/dest/mrs_bool/initAudio", true);
  //playbacknet->updctrl("SoundFileSink/dest/mrs_string/filename", "out.wav");

  while (playbacknet->getctrl("SoundFileSource/src/mrs_bool/hasData")->to<mrs_bool>() ) {
    playbacknet->tick();
  }
  delete playbacknet;
}


int main (int argc, const char **argv) {
  mrs_string fileName;

  if (argc < 2) {
    cout << "Please enter filename." << endl;
    exit(1);
  } else {
    fileName = argv[1];
  }
  cout << "Playing file " << fileName << endl;

  sfplay(fileName);
  exit(0);
}

I followed this post(http://marsyas.info/assets/docs/manual/marsyas-user/Compiling-on-MacOS-X-10_002e6-Snow-Leopard.html) using cmake GUI and had the following error. I tried to move up one level in my directory, still no luck.

I then tried to use cmake in terminal but got a different error when "make"

any pointer on how to proceed? thanks

I have seen in the library an example app using a NDK / JNI binding for Marsyas. I suppose it is possible to port the project to iOS since. Not sure if other libraries included like RTAudio supports the iOS Core Audio.

Anyone tried ?

This is the command invoked: ./bextract bextract_single.mf -w ms.arff -p ms.mpl -pm -mc -wsoutput

I have made some changes to marsyas components(WavFileSink,Confidence,SoundFileSource & Sink) and also introduced SoundFileSink to the early fanout. It's mostly to read mic/rtsp at runtime and send confidence and wav output over to websockets. No change is expected to kick in during training but only during classification runtime.

Any indication why this error might happen? It fails exactly when a first label of songs are trained and it goes to the second label of songs.

Thanks.

I get the following message when I try to install marsyas on Debian 8 with MATE 1.8.1:

CMake initialized in the wrong directory. Please initialize CMake with the top-level Marsyas directory as source directory.

I followed instructions from here: http://marsyasweb.appspot.com/assets/docs/manual/marsyas-user/Configuring-with-CMake.html#Configuring-with-CMake

Hi there, since I honestly don't know/understand if it's MARSYAS field of application, I recently discovered a very cool lib called Aurio "that focuses on audio processing, analysis, media synchronization and media retrieval and implements various audio fingerprinting methods".

Its drawback is that has been developed in C# for .NET, so it's Windows-only.

It would be really great to establish some kind of collaboration between projects in order to (finally) obtain a platform-indipendent open source automated a/v synchronizer.

Hope that inspires.

I am getting stuck when I try to build with vamp plugins. I realized I am clearly missing libmvamp. I looked on the Vamp Plugins section of marsyas.info and they are no longer available to download. Could someone put that library back on the page? @gtzan

I'm currently maintaining marsyas for Arch Linux. python2 is now EOL and the distribution is en route to removing it from the repositories. I'm therefore removing the (optional) dependency on python2 from the marsyas package, as the python module can only be built for python2.

It would be great, if this was ported to python3!

When calling the tempo binary with the -f option to write the output to a separate file, and that file contains a space character, the output is written to a file named anything up to the space character, even when quoting.

Example:

tempo -f "my file.txt" "audio.wav"

This will create a file called my with the result.

tempo -f my\ file.txt "audio.wav"

Using a backslash like above, leads to the same result.

Tested on macOS 10.14.1 with marsyas-0.5.0.

Marsyas' sfinfo binary conflicts with audiofile's sfinfo.

Due to the above mentioned bug with Arch Linux, I'm renaming it to marsyas-sfinfo, but I think a better name should be found here for all the helper apps.

Given the fact, that the last version was released 4(!) years ago, but that there are over 200 commits to master since then, I would love to see a more frequent release model for this software!

Who is currently in charge of this project and can do it?
