ofxaudioanalyzer's Introduction

ofxAudioAnalyzer

Description

openFrameworks addon for audio analysis. It provides the following algorithms :

RMS, Instant power, Energy, Pitch frequency, Pitch Confidence, Pitch Salience, HFC, Centroid, Inharmonicity, Spectral Complexity, Dissonance, Roll Off, Odd To Even Harmonic Energy Ratio, Strong Peak, Strong Decay, Onsets, Spectrum, Mel Bands, MFCC, Harmonic Pitch Class Profile, Tristimulus

See AlgorithmsReference.md

This addon uses Essentia library.

Compatibility

OSX & Linux - OF 0.10.0

Tested with OSX 10.11.6 and Ubuntu 14.04

Compilation

Linux: Makefiles.
OSX: The best and easiest way is to use Xcode Projects. You can also use the makefiles, but in OSX you'll need to add ofxAudioDecoder to addons.make.

Dependencies

For playing and analyzing audio files (see Audio File Player), ofxAudioDecoder addon is needed for OSX.

Usage

The examples included in the repository can be used to build new projects specially the empty ones. They can be compiled with Xcode or by Terminal using the Makefiles.
Creating a new project:
- Create a new project using the Project Generator. Be sure to include ofxAudioAnalyzer and ofxAudioDecoder addons.
- Include ofxAudioAnalyzer header into ofApp.h
```
  #include "ofxAudioAnalyzer.h"
```
- Create an instance of ofxAudioAnalyzer into ofApp class:
```
ofxAudioAnalyzer audioAnalyzer;
```
- In the setup() function setup the audioAnalyzer's parameters (sampleRate, bufferSize, channels). Be sure that the parameters of the audioAnalyzer match the parameters of the ofSoundStream or the audio files you load to the sound player to avoid errors:
```
audioAnalyzer.setup(44100, 512, 2);
```
- Analyze the ofSoundBuffer in ofApp::audioIn() and ofApp::audioOut() when using ofSoundStream, or in the ofApp::update() if you are using audio file player, ofSoundBuffer parameters must always match audioAnalyzer's:
```
audioAnalyzer.analyze(soundBuffer);
```
- Retrieve analysis results specifying algorithm, channel, smooth amount and if you want it normalized (Smoothing and normalizing are optionals. Normalizing is not necessary for all algorithms, some of them output values from 0.0-1.0 by default. See allAlgorithms example):
```
float rms = audioAnalyzer.getValue(RMS, channel, smoothAmount, doNormalize);
```

Audio File player

This repository includes an extended version of ofBaseSoundPlayer taken and modified from: https://github.com/YCAMInterlab/ofxTimeline/tree/master/libs/ofOpenALSoundPlayer_TimelineAdditions/src.

This class [ofSoundPlayerExtended] lets you load, play and analyze audiofiles (wav & mp3). See examples: allAlgorithms, audioFilePlayer and onsets to understand how it works.

In OSX, ofSoundPlayerExtended uses ofxAudioDecoder. This fork was used for testing the examples https://github.com/leozimmerman/ofxAudioDecoder .
Linux: ofxAudioDecoder, is not compatible with Linux. For replacing it you need to use mpg123 lib. See this forum's thread to know how to make sure OF uses it: https://forum.openframeworks.cc/t/error-running-soundplayerexample-on-the-pi/13197/6?u=lzmmrman

(!) ofSoundPlayerExtended is not really necessary for the addon to work. If you don't need or it's giving to much errors, just remove it from Xcode project or the addon's /src directory.

Assistance with min max values for GUI sliders

Hi @leozimmerman I'm getting back into openFrameworks after a few months off and really liking what you've done with ofxAudioAnalyzer. I've changed it to use ofParameter and have set it up to work with ofxGuiExtended. But I'm not sure what the min and max values should be for all the float sliders. Any chance you could assist with this? Cheers.

Libraries missing while running on other machine

Hi,

I have a problem with the linking of the depending libraries (I think).
When I follow the instructions from the Readme I can succesfully build and run my project. But when I try to run my app on another machine it doesn't start and gives an error, saying:
Dyld Error Message: Library not loaded: /usr/local/opt/taglib/lib/libtag.1.dylib
Reason: image not found
All the libraries, mentioned in the Readme, are under 'Link Binary With Libraries' in the Build Phases.
I'm quite new to the linking of libraries, so I'm not sure what to do.

Thanks :)

Any idea to make it work on Windows?

any chance to compile on Windows?
Essentia looks multiplatform and also https://github.com/npisanti/ofxAudioFile could work as file loader maybe.

cairo.h not found

I had to delete all the obj folders in order to use the addon

VAD - voice activity detection

Nice add-on.

For a new project I was hoping to do VAD to know when people are speaking (maybe even singing) and I was wondering if your audio analysis could be used for it?

Do you think it's possible to build on what you have to add VAD (voice activity detection)?

Thanks

Error while linking to essentia

Hi,
Trying to compile on UbuntuStudio 16.04 with standard Linux tools.
I get errors while linking. I suspect a wrongly define compiler macro but not sure how to correct it
if it is indeed the case. I have also compiled and installed essentia in case there was an issue with the static library shipped.

Thanks for the help.

Compatibility with OF 0.11

Hi,

Is ofxAudioAnalyzer compatible with OF 0.11 ?

Thanks,

need of ofBaseSoundPlayer.h to make it work in OF 0.10

Hello,
I would like to implement your library in a research project made in OF 0.10. To implement ofBaseSoundPlayer.h, just coping it into the new sound library in OF would be enough to make it work?
Any suggestion?

Error include <MobileCoreServices/MobileCoreServices.h on audiodecodercoreaudio.h file.

While compiling the under MacOS Sierra, it complains that

"include <MobileCoreServices/MobileCoreServices.h on audiodecodercoreaudio.h file." not found.

I solved it by using
#ifdef TARGET_OF_IOS

instead of
#ifdef TARGET_OF_IPHONE

Building a new libfftw3f.a on Linux was required

In case anyone needs this, this is how I made it work:

cd /tmp/
wget https://www.fftw.org/fftw-3.3.10.tar.gz
untar fftw-3.3.10.tar.gz
cd fftw-3.3.10
./configure --prefix /tmp/FFT/ --enable-float
make
make install
cp /tmp/FFT/lib/libfftw3f.a ~/src/openFrameworks/addons/ofxAudioAnalyzer/libs/fftw3f/lib/linux64/

MFCC errors?

dct_f.assign(10,0 );

while numberCoefficients (integer ∈ [1, ∞), default = 13) : 13 is the number of output mel coefficients.
http://essentia.upf.edu/documentation/reference/streaming_MFCC.html

Should it be dct_f.assign(13,0 )?

I changed the two line and got 13 coefficients. keep 2-13 as coefficients, the first is energy?

dct_f.assign(13,0 )?
dct = factory.create("DCT", "inputSize", 24, "outputSize", 13);

thanks

unable to compile on 10.10 with given instructions

I have followed the instructions in the readme and installed all dependencies trough the provided link, added the files to the project and added the needed paths to the project. I am using the 64bit version of openframeworks. However when I try to compile the example projects, I get about 75 linking errors like:

Undefined symbols for architecture x86_64:

addon compilation issue with qt on mac

Hello,

I've been trying to compile this addon with Qt 5.7.0 on mac OS 10.12.1. Using .qbs build system.

I'm getting the following linker error:
ld: framework not found /Users/burakertekin/openFrameworks/addons/ofxAudioAnalyzer/OpenAL clang: error: linker command failed with exit code 1 (use -v to see invocation) Process failed with exit code 1.
Although, I've added OpenAL to frameworks list in qbs file. Do I have to compile this addon somehow? Anybody have an idea on this?

Thanks!

Program hangs on AudioAnalyzer::analyze

My SoundBuffer is being initialized and updated correctly but once I try to run AudioAnalyzer::analyze(SoundBuffer) my program hangs and my audio buffer freezes with all 0's
I followed the example but they are using older versions which ask for a SoundBuffer as an input.

`{void ofApp::audioIn(float * input, int bufferSize, int nChannels){

float buffer1[bufferSize];
float buffer2[bufferSize];

for(int i = 0; i < bufferSize ; i += 1) {
    buffer1[i] = input[i*nChannels];
    buffer2[i] = input[i*nChannels+1];
    
}


//Feeding float array into a SoundBuffer
pop.copyFrom(buffer1, 512, 2, 44100);

audioAnal.analyze(pop);

Examples not building on OSX 10.12, OF 9.4

Problem is with ofxAudioDecoder, which can't seem to find <audioencoder.h>

any ideas how to fix?

Deprecation warnings in all examples

All examples use the following style setup:

soundStream.setup(this, outChannels, inChannels, sampleRate, bufferSize, 3);

Apparently this setup function is deprecated, but I can't find any example or documentation on how to properly use ofSoundStreamSettings. An example selecting a specific audio device would be useful.

Multiple compilation errors in ofSoundPlayerExtended.cpp on linux

I'm getting a few errors when attempting to compile this for the first time. (This is after removing the '-Werror=return-type' compiler flag because that was catching errors in this addon too.) This is a fresh clone of ofxAudioAnalyzer and openFrameworks. I'm trying to compile an empty project that has this and a few other addons included before I start developing in the new project.

First error seems to be a prototype error:

/home/trent/documents/github/openFrameworks/addons/ofxAudioAnalyzer/src/ofSoundPlayerExtended.cpp:165:6: error: prototype for ‘bool ofSoundPlayerExtended::mpg123ReadFile(std::__cxx11::string, std::vector<short int>&, std::vector<float>&)’ does not match any in class ‘ofSoundPlayerExtended’

The second is that ‘getMpg123EncodingString’ was not declared:

Operating System: Ubuntu 18.04.1 LTS
I'm just using openFrameworks and ofxAudioAnalysis from master.

audioIn crashing when exiting app

Hi!

My app is sometimes crashing when exiting the application in the com.apple.audio.IOThread.client;
Apparently the rtStreamPtr pointer is already null;

-> rtStreamPtr->soundInputPtr->audioIn(rtStreamPtr->inputBuffer);

Before exiting the app I call the functions:

ofSoundStreamStop();
audioAnalyzer.exit();

But it still crashes every two times. The inconsistency makes me think it can be a multithread issue, but I don't know where else should I call it.

Any thoughts?

New examples request

Thanks for your work. Any chance to include examples to illustrate some of the other essentia algorithms such as chord detection or beat detection?

Compiler erros in Release mode

I'm a huge fan of this library. I need some help compiling in Release mode.
The error is also replicated by compiling example-allAlgorithms.
Using Xcode 13.2.1 and OF 0.11.2
In Debug mode all works fine.

The errors:
