| 2 | |
|---|
| 3 | * Overdue: After more than five years of development behind the curtain, |
|---|
| 4 | time has come to release a new version of aubio. |
|---|
| 5 | |
|---|
| 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. |
|---|
| 9 | |
|---|
| 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. |
|---|
| 12 | |
|---|
| 13 | * Optimization: the FFT, central to most algorithm, 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. |
|---|
| 17 | |
|---|
| 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. |
|---|
| 21 | |
|---|
| 22 | * src/: source and header files are now organized in sub-directories. |
|---|
| 23 | |
|---|
| 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. |
|---|
| 28 | |
|---|
| 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. |
|---|
| 31 | |
|---|
| 32 | * src/onset, src/tempo/, src/pitch: the different methods for onset, tempo, |
|---|
| 33 | and pitch extraction have seen many bug-fixes and optimizations. |
|---|
| 34 | |
|---|
| 35 | * src/spectral/specdesc.h: new onset distances and statistical measures have |
|---|
| 36 | been added. |
|---|
| 37 | |
|---|
| 38 | * src/spectral/filterbank.h: new filter bank to compute the energy in any |
|---|
| 39 | custom-defined frequency bands. |
|---|
| 40 | |
|---|
| 41 | * src/spectral/mfcc.h, examples/aubiomfcc.c: a standard implementation of |
|---|
| 42 | the Mel-Frequency Cepstrum Coefficients algorithm has been added. |
|---|
| 43 | |
|---|
| 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 |
|---|
| 46 | sampling rates. |
|---|
| 47 | |
|---|
| 48 | * src/synth/wavetable.h, src/synth/sampler.h: provide basic ways to generate |
|---|
| 49 | some sounds. |
|---|
| 50 | |
|---|
| 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. |
|---|
| 53 | |
|---|
| 54 | * src/lvec.h: lvec_t provides a double precision vector, required for some |
|---|
| 55 | operations to avoid floating point overflow |
|---|
| 56 | |
|---|
| 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 |
|---|
| 59 | bank. |
|---|
| 60 | |
|---|
| 61 | * examples/: several new options, including new programs, have been |
|---|
| 62 | included. Refer to the documentation for details. |
|---|
| 63 | |
|---|
| 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. |
|---|
| 66 | |
|---|
| 67 | * doc/web.cfg: a simplified Doxygen configuration produces a simpler html |
|---|
| 68 | documentation. |
|---|
| 69 | |
|---|
| 70 | * doc/*.txt: the manpages have been rewritten for txt2man. |
|---|
| 71 | |
|---|
| 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. |
|---|
| 74 | |
