C++ Audio and Music DSP Library

Hi, i'm really interested in using Maximillian's FFT capabilities, but when i run the fft example from the examples folder in VS 2015, it doesn't compile? Does anyone have a solution? Thanks in advance!

Hi Mick,

Got an urgent question. I have been building an audiovisual granular synth for my PhD and my examination performance is on Friday. I am getting run time crashes at least 3 times a day relating to the double* getWindow function in maxiGrainWindowCache. (See image below)

Would you be able to suggest how or why this is continually occurring? Or what safe guards I could do temporarily to ensure that this never happens during my examination? Any advice or tips at all at this stage would help my sanity immensely. Thanks!

Hi!

First, thanks and congratulations with Maximilian, it works great and is well optimized.

I use it on OpenFrameworks for iOS. I don't manage to do a simple stuff: a very basic granular synthesis. I would like to play a orchestral wav file with position (in the wav file) as a parameter. I explain, i would like to have 16 grain players, and every xx milliseconds (xx = random numbers) one of these players plays a very short part of the file (at the right play head position), with no loop. Because there are 16 players and they play very quickly small grains, it gives you the impression that the play head stays immobile. I made a Max/MSP patch and it works well, but i cannot make it in OpenFrameworks / Maximilian.

Hope my explanation is obvious. Thanks for your help!

Cheers, Olivier

i'm trying to compile a small app i got running is OSX and tried to port it to Ubuntu (CodeBlocks 10.05)

i got this errors :

../../../addons/ofxMaxim/libs/maxiMFCC.h|62|error: there are no arguments to ‘malloc’ that depend on a template parameter, so a declaration of ‘malloc’ must be available [-fpermissive]| ../../../addons/ofxMaxim/libs/maxiMFCC.h|67|error: there are no arguments to ‘malloc’ that depend on a template parameter, so a declaration of ‘malloc’ must be available [-fpermissive]| ../../../addons/ofxMaxim/libs/maxiMFCC.h||In member function ‘void maxiMFCCAnalyser::calcMelFilterBank(double, int)’:| ../../../addons/ofxMaxim/libs/maxiMFCC.h|128|error: there are no arguments to ‘malloc’ that depend on a template parameter, so a declaration of ‘malloc’ must be available [-fpermissive]| ../../../addons/ofxMaxim/libs/maxiMFCC.h|139|error: there are no arguments to ‘malloc’ that depend on a template parameter, so a declaration of ‘malloc’ must be available [-fpermissive]| ../../../addons/ofxMaxim/libs/maxiMFCC.cpp||In member function ‘void maxiMFCCAnalyser::dct(T_) [with T = double]’:| ../../../addons/ofxMaxim/libs/maxiMFCC.cpp|16|error: ‘vDSP_mmulD’ was not declared in this scope| ../../../addons/ofxMaxim/libs/maxiMFCC.cpp|18|error: ‘vDSP_vsdivD’ was not declared in this scope| ../../../addons/ofxMaxim/libs/maxiMFCC.cpp||In member function ‘void maxiMFCCAnalyser::dct(T_) [with T = float]’:| ../../../addons/ofxMaxim/libs/maxiMFCC.cpp|23|error: ‘vDSP_mmul’ was not declared in this scope| ../../../addons/ofxMaxim/libs/maxiMFCC.cpp|25|error: ‘vDSP_vsdiv’ was not declared in this scope| ../../../addons/ofxMaxim/libs/maxiMFCC.cpp||In member function ‘void maxiMFCCAnalyser::melFilterAndLogSq_Part2()’:| ../../../addons/ofxMaxim/libs/maxiMFCC.cpp|58|error: ‘powerSpectrum’ was not declared in this scope| ../../../addons/ofxMaxim/libs/maxiMFCC.cpp||In member function ‘void maxiMFCCAnalyser::melFilterAndLogSq_Part2() [with T = double]’:|

i've already added the #include as memset and memalloc where not found ...

hope it's usefull ...

hi @micknoise,

im working with ofxMaxim in OF on iOS. basically, im trying to load a song from my iphones music library, convert it to a wav and have ofxMaxim do some cool shit with it :)

so far ive been successful in converting the library file to a wav file and storing it in the documents folder of the app to be then loaded by ofxMaxim, but this is where it trips up...

ive done lots of tests and worked out that when iOS exports a PCM wave file, it adds a "audio data file offset" of 4096 bytes. a normal wav file that works with ofxMaxim has a "audio data file offset" of 44 bytes. otherwise the files are identical when inspecting using the AFInfo command in terminal.

im thinking maximilian needs to find out what this "audio data file offset" value is before it starts reading the file into memory. ive had a hack around in maxiSample::read function but its a bit over my head at the moment.

is the solution to this something apparent to you?

cheers, L.

Hey everyone,

I'm trying to run maximilian in xcode 3.2.6 and open frameworks 0071 but i get errors in "maxiatom.cpp". It goes like this:

.../addons/ofxMaxim/libs/maxiAtoms.cpp:74: error: cannot convert 'double_' to 'float_' for argument '1' to 'void vDSP_vlint(float_, float_, vDSP_Stride, float*, vDSP_Stride, vDSP_Length, vDSP_Length)'

../addons/ofxMaxim/libs/maxiAtoms.cpp:112: error: no matching function for call to 'min(unsigned int&, long unsigned int)'

Does anybody know how to fix this?

Thanks

Summary: Main changes to Web Audio build – transpiled javascript version of the library is included in this repository, for both Script Processor Nodes and Audio AudioWorklets.

Other changes:

README -> README.md src - now holds the C++ src, the C++ libs and the embindings. js - holds ScriptProcessorNode (asm.js legacy) and audioWorklet (Wasm) dirs, each with it's own * makefile, build directory, shared libs, examples, and a python webserver script for convenience of testing. cpp - holds C++ client code and project (basically the old stuff).

Hello I am new to C++ and would like some help on getting started with Maximilian.... I am on Windows XP running Visual Studio 2010 Premium

Any help in sorting these errors would be great

Been a while since I looked at this. But trying to compile on Ubuntu 13.10 I get the following (from the command line).

OSS :

RtAudio.cpp:6391:23: fatal error: soundcard.h: No such file or directory #include "soundcard.h"

ALSA : RtAudio.cpp:5148:28: fatal error: alsa/asoundlib.h: No such file or directory #include <alsa/asoundlib.h>

Jack : RtAudio.cpp:1798:23: fatal error: jack/jack.h: No such file or directory #include <jack/jack.h>

Are there files? Submodules missing? Or is there something I need to install / do before trying to compile?

When reading the first channel from a 2 channel file, the read function crashes. this code seems wrong

if (myChannels>1) {
            int position=0;
            int channel=readChannel*2;
            for (int i=channel;i<myDataSize +6;i+=(myChannels*2)) {
                myData[position]=myData[i];
                myData[position+1]=myData[i+1];
                position+=2;
       }
}

I removed the +6 from this line and so the crash no longer occurs;

for (int i=channel;i < myDataSize +6;i+=(myChannels*2)

so now it looks like this

for (int i=channel;i<myDataSize ;i+=(myChannels*2) // removed +6

why is that +6 there? the index of myData should not go beyond myDataSize?

In maxiSampler::play()

outputs[i]=samples[i].play(pitchRatios[(int)pitch[i]+originalPitch]*((1./samples[i].getLength())*maxiSettings::sampleRate),0,samples[i].getLength())*envOut[i];

Hello, great to see the project being actively maintained.

We're adding support for compiling Maximilian patches on the OWL platform, which is an open source embedded hardware ecosystem thingy-jig. We've got an online patch library and compiler here.

This means in short that our users will be able to write their own patches using Maximilian and run them on OWL hardware. Other supported languages are plain C++, FAUST, Pure data, Max Gen and most recently SOUL, so you're in good company :)

To get this to work on a bare-bones (no OS) embedded audio device we've had to adapt the library files a bit. Some of these changes are specific to our platform, others would be nice to contribute back upstream.

In particular I'd like to lobby for a new feature (which I briefly discussed with Mick ages ago), which is maxiParam. maxiParam is a value object which can be used instead of a double, but which can be updated outside of the patch context. Using maxiParam allows us to map parameters to a hardware knob or button, and so provides easy user control for patch parameters like gain, frequency, et c. It's just as useful for connecting into any other user interface, a GUI or plugin format.

Rather than post a big PR I decided to open this issue and start a dialogue. What is the best way to proceed?
