3 * Overdue: After more than five years of development behind the curtain,
4 time has come to release a new version of aubio.
6 * General: The library has been completely revised since 0.3.2. The API has
7 seen a major clean up, and has been thoroughly tested. The following list of
8 changes is not exhaustive.
10 * Memory management: allocation and freeing of memory has been optimized in
11 many ways. Several memory leaks and out of bound access have been fixed.
13 * Optimization: the FFT, central to most algorithms, can now be computed
14 using different optimized algorithms, depending on what is available on your
15 platform (FFTW, Ooura, or vDSP). Other simple optimization tricks are
16 included. Most can be deactivated by configuring the build accordingly.
18 * python/: The python interface has been completely rewritten to use numpy C
19 interface, making the aubio python module order of magnitudes faster than
20 the previous version. Several demos and tests are included.
22 * src/: source and header files are now organized in sub-directories.
24 * src/io/source.h: new source readers can now use any or all of libav,
25 CoreAudio, and libsndfile. This means that aubio can now easily read most
26 uncompressed and compressed formats. Compiled with libav, aubio can also
27 read audio from video files, and over the network.
29 * src/io/sink.h: a new sink object lets you write wav files with any number
30 of channels, at any samplerate, using libsndfile or CoreAudio.
32 * src/onset, src/tempo/, src/pitch: the different methods for onset, tempo,
33 and pitch extraction have seen many bug-fixes and optimizations.
35 * src/spectral/specdesc.h: new onset distances and statistical measures have
38 * src/spectral/filterbank.h: new filter bank to compute the energy in any
39 custom-defined frequency bands.
41 * src/spectral/mfcc.h, examples/aubiomfcc.c: a standard implementation of
42 the Mel-Frequency Cepstrum Coefficients algorithm has been added.
44 * src/temporal/{a,c}_weighting.h: standard implementation of the C-weighting
45 and A-weighting pre-processing filters are now provided for most commons
48 * src/synth/wavetable.h, src/synth/sampler.h: provide basic ways to generate
51 * src/fvec.h: fvec_t, the vector object central to most aubio algorithms, is
52 now single channel. This simplifies the code of each algorithm greatly.
54 * src/lvec.h: lvec_t provides a double precision vector, required for some
55 operations to avoid floating point overflow
57 * src/fmat.h: fmat_t provides a single precision matrix, useful for
58 multi-channel operations and to some algorithms such as the spectral filter
61 * examples/: several new options, including new programs, have been
62 included. Refer to the documentation for details.
64 * tests/: several tests and examples programs have been added. This should
65 be a good place to look at to understand how to use aubio.
67 * doc/web.cfg: a simplified Doxygen configuration produces a simpler html
70 * doc/*.txt: the manpages have been rewritten for txt2man.
72 * Build system: the build system has been switched from autotools/automake
73 to waf. Type './waf' or see README.md for instructions on how to use waf.
