Overview

aubio

aubio is a library to label music and sounds. It listens to audio signals and attempts to detect events. For instance, when a drum is hit, at which frequency is a note, or at what tempo is a rhythmic melody.

Its features include segmenting a sound file before each of its attacks, performing pitch detection, tapping the beat and producing midi streams from live audio.

aubio provide several algorithms and routines, including:

several onset detection methods
different pitch detection methods
tempo tracking and beat detection
MFCC (mel-frequency cepstrum coefficients)
FFT and phase vocoder
up/down-sampling
digital filters (low pass, high pass, and more)
spectral filtering
transient/steady-state separation
sound file read and write access
various mathematics utilities for music applications

The name aubio comes from audio with a typo: some errors are likely to be found in the results.

Python module

A python module for aubio is provided. For more information on how to use it, please see the file python/README.md and the manual .

Tools

The python module comes with the following command line tools:

aubio extracts informations from sound files
aubiocut slices sound files at onset or beat timestamps

Additional command line tools are included along with the library:

aubioonset outputs the time stamp of detected note onsets
aubiopitch attempts to identify a fundamental frequency, or pitch, for each frame of the input sound
aubiomfcc computes Mel-frequency Cepstrum Coefficients
aubiotrack outputs the time stamp of detected beats
aubionotes emits midi-like notes, with an onset, a pitch, and a duration
aubioquiet extracts quiet and loud regions

Recognizing VS 2017 / msvc 14.10, static vs shared libs, MD/MT
I am currently trying to create a vcpkg port for aubio and I am having various problems:

msvc 14.10 (=VS2017) is not recognized, maybe because of a new path-logic? CL is now at: C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.10.25017\bin\HostX64\x64\CL.exe;

a problem I have not understood yet is an error-message that aubio.lib was created twice. Might it be, that the export lib and the static lib are created with the same filename so that one overwrites the other?

I would like to find a way to make one build compile shared libs only, and another separate build compile static libs only. Is that possible, e.g. with a configure option?

also it seems that the dll is not installed in the bin directory. Only the exe's are.

finally I would also like to be able to control static vs dynamic CRT linkage (MD/MT) through the build configuration. Is that possible?

Thank you in advance for any help.

Aubio on Pypy?

Hi, It looks liike waf build works on pypy, the python bindings themselves do not build because of the error below, I wonder how possible it is to get this working with pypy?

I guess at worst it could be reimplementing using cffi, on the other hand it might just be tweaking the bindings a bit ..

Help required using Aubio in Swift iOS project

Hi, I'm new to both iOS(swift) and to aubio. I just want to implement a simple functionality of pitch detection in my app, by passing an audio file to aubio, and have it return the pitch value in Hz with timestamp. While I've been able to do this with the command line using 'aubiopitch', I've no idea how to do it in iOS(swift). Right now I've included the aubio framework inside my app and included the Accelerate framework, and created a bridging header to include the header files. Can somebody please help me out with a basic implementation of the above said functionality?

Segmentation fault: 11 on demo_tempo.py

I'm on a 2013 MacBook Pro Retina with 8 GB of RAM, I'm not familiar with C or its implementation. I'm unable to get the demo_tempo working due to a segmentation fault.

using the command python demo_tempo.py <file>.mp3

Perhaps I am using it incorrectly? It also occurs if I use a .wav, or add in the samplerate as a parameter.

Thanks,

Caleb

memory leak or no garbage collection?

Hi,

I'm trying to use aubio to calculate bpms for bunch of files in a row. After thorough investigation I've found out that problem is either in the depths of aubio module or in failing python garbage collection. Consider the following code (python 2.7, was taken from example):

from aubio import tempo, source
import time

# tempo detection delay, in samples
# default to 4 blocks delay to catch up with

# this emulates 10 files
for _ in xrange(0, 10):
    win_s = 512                 # fft size
    hop_s = win_s / 2        # hop size

    samplerate = 0
    s = source('test.wav', samplerate, hop_s)
    samplerate = s.samplerate
    o = tempo("default", win_s, hop_s, samplerate)

    # list of beats, in samples
    beats = []

    # total number of frames read
    total_frames = 0

   # actual leaking is inside loop
    while True:
        samples, read = s()
        is_beat = o(samples)
        if is_beat:
            this_beat = o.get_last_s()
            beats.append(this_beat)
        total_frames += read
        if read < hop_s: break

    print _
    time.sleep(3)

time.sleep(4)

I've added sleeps to make it handy for spotting on growing memory percentage. On my system (4G of ram), this script goes from 1.2% to 12%. As for python garbage collection, setting all used variables in loop and after it to None, deleting them and adding gc.collect() does not help, memory continue to grow.

Using aubio 0.4.5 in a Windows environment

Dear Sir or Madam,

I recently downloaded aubio 0.4.5 for Windows (64-bit architecture), with ffmpeg build. I would like to explore the pitch detection functionality. But I am new to aubio, C and Python. I am not sure where to begin if I want to analyse audio!

Google searches seem to imply that aubio is run through the command line, but I'm not sure exactly how to use the command line and aubio to analyse an audio file.

I would appreciate it if you could point me in the right direction, so I can actually start using aubio!

Yours faithfully,

Caleb Owusu-Yianoma

Forever loop while getting tempo on iPhone 5
Hello,

I got this issue while i was trying to get tempo value of a song. I have tried to do this on arm64 devices like iPhone6, iPhone6+, it doesn't happen. It just appear in iPhone5, i guest it may be cpu arch problem, because iphone 5 is 32 bit CPU, while iPhone 6 and 6+ is 64 bit CPU. I do some debugging and found cause of problem come from beattracking.c, this line:

phase = fvec_quadratic_peak_pos (bt->phout, maxindex);

Value of the phase variable after this calculation is nan. Later, the beat value is calculated on phase value, so beat become nan too. And here is the loop that can not break because beat + bp is always nan

while (beat + bp < 0) { beat += bp; }

My question is: How to fix this problem?

Thanks,

Failed opening 'filename' (could not find 'fmt' in RIFF header)
Hi there,

I just cloned the aubio git repository to try the different onset and pitch detection techniques on some of my own recordings. I am using the python library.

However, on this audio file (and on any other audio file I have tried), I get the following error:

(aubio) pavlos55@pavlos55-SATELLITE-S50-B:~/aubio/python/demos$ python demo_onset_plot.py 3stSTRING.WAV Traceback (most recent call last): File "demo_onset_plot.py", line 19, in <module> s = source(filename, samplerate, hop_s) RuntimeError: AUBIO ERROR: source_wavread: Failed opening 3stSTRING.WAV (could not find 'fmt ' in RIFF header)

I have also tried with Python3 with no success.

Aubio with line-in/microphone in realtime from python ?

Is it possible to use aubio with realtime audio in python - whether that's aubio interfacing with something like pulseaudio, or setting up all the audio in python, with e.g. pysoundcard (the new version of pyaudio) ?

Using command line options in Python

I couldn't find any thing about this in docs: is it possible to use options available for the command line in the Python side too? I am particularly interested in aubioonset's options (e.g. threshhold, using jack etc.)

Thank you!

Bar detection?

I use aubio in lighting control software (glight), where I use it for real-time beat detection and moving lights to the beats. This works really well. I'm now looking to extend this to "bar" detection, i.e. to include knowledge of when a bar starts and how many beats are in bar. Is this possible with aubio? If not, would this be an interesting feature request?

Add an aubiolevel CLI tool to compute the sound pressure level

Aubio enables users to compute the sound pressure level of a buffer using miscutils.h, but there is no way to get that information from CLI tools right now.

This adds support for a standalone CLI tool so that extracting sound pressure level information does not require building a program against the library.

I have created this for my own needs and figure it could useful for the upstream as well.

0.4.6(Oct 4, 2017)
Version 0.4.6 includes:

yinfast, a new version of the YIN pitch detection algorithm, that uses spectral convolution to compute the same results as the original yin, but with a cost O(N log(N)), making it much faster than the plain implementation (O(N^2))

Intel IPP optimisations (thanks to Eduard Mueller), available for Linux, MacOS, Windows, and Android

improved support for emscripten (thanks to Martin Hermant), which compiles the aubio library as a javascript module and lets you run aubio's algorithms directly from within a web-page.

0.4.6 also comes with several bug fixes and improvements.

Many thanks to Eduard Mueller (@emuell), Martin Hermant (@MartinHN), Hannes Fritz (@hztirf), Stuart Axon (@stuaxo), Jörg (@7heW4yne), ssj71 (@ssj71), Andreas Borg (@borg), Rob (@mlrobsmt) and everyone else for their valuable contributions and input.

0.4.5(Apr 10, 2017)
A new version of aubio, 0.4.5, is available.

This version features:

a new aubio python command line tool to extract information from sound files

improved default parameters for onset detection, using adaptive spectral whitening and compression

support for libswresample

New options --miditap-note and --miditap-velo have been added to aubioonset and aubiotrack to adjust the note and velocity of the midi note emitted by onsets and beats.

0.4.5 also comes with a bunch of fixes, including improved documentation, build system fixes, and platform compatibility.

Many thanks to Martin Hermant (@MartinHN), Sebastian Böck (@superbock), Travis Seaver (@tseaver) and others for their help and contributions.

0.4.4(Mar 28, 2017)
This version features a new logging module that allows redirecting errors, warnings, and other messages coming from libaubio. As usual, these messages are printed to stderr or stdout by default.

Another new feature is the --minioi option added to aubioonset, which lets you adjust the minimum Inter-Onset Interval (IOI) separating two consecutive events. This makes it easier to reduce the number of doubled detections.

New demos have been added to the python/demos folder, including one using the pyaudio module to read samples from the microphone in real time.

0.4.3(Mar 28, 2017)
This version features a complete rewrite of the python module, making it faster and more memory efficient than any previous version. It also adds compatibility for Python 3.x.

The build system has been improved so that python-aubio can now be installed with pip using a simple command:

$ pip install aubio

0.4.3 also comes with a number of improvements and several optimisations, so you should see both the library and the python module run significantly faster. Many computations have been vectorised, using either Atlas/cblas or the Accelerate framework, depending on the host platform.
