2000-09-11 Silvia Pfeiffer * Version 0.0.2 - src/tier1: sped-up processing; is realtime now for Layers 1+2 - src/tier2: included an XML interface using the gnome-xml-library - src/tier2: included an automatic comparison of segmentation results using the XML interface - src/tier2: created a general segmentation function in tier2 that gets used by silence and noise segmentation and that has a few more parameters - src/tier2: included a histogram facility for the segmentData class - src/tier2: included a histogram difference facility in the analyser class that calculates a difference curve on sliding histograms - test/analyseMPaudio.cc: uses the histogram difference facility with loudness for scene segmentation 2000-12-22 Silvia Pfeiffer * Version 0.0.3 - src/tier1: added a few functions to MDecoder to hook it up with bewdy - released the GUI bewdy (implemented by Conrad Parker ) under Version 0.0.5 2001-01-22 Silvia Pfeiffer and Conrad Parker * Version 0.1.0: NOT BACKWARD COMPATIBLE! - src/tier2: created the module interface to dynamically load analysis modules from plugin libraries - src/tier2: extracted all analysis functionality to external libraries some of which are not included in this distribution any more :-) - test/analyseMPaudio.cc: adapted to use module interface 2001-01-29 Silvia Pfeiffer - started Version 0.1.1 - src/tier1/Decoder.cc: fixed a bug in decode_frame function 2001-11-23 Silvia Pfeiffer and Thomas Vincent * Version 0.1.2 - src/plugins_brief: a new easier interface to load and use modules - src/tier2: change in normalise segment data, now can normalise with a clipping effect - src/tier1: MPEGfile inherits from a new class Sbprep that gives useful tools to analyse such as mean, rms and normalised subband energies of samples over channels in stereo (and jstereo) mode, and over a whole granule. - src/plugins: a set of new modules: centroid, normalised subband energies, signal energy, signal magnitude, pause rate, band energy ratio, roll off, bandwidth, signal bandwidth, spectral flux, central moment, all working with the new interface given by Sbprep. Useful tools for modules are also available in tools.H. 2001-12-01 Thomas Vincent * Version 0.2.0: NOT BACKWARD COMPATIBLE! A step toward a generic frequency-domain audio analysis tool - src/tier2: adding partial sum and average. - src/tier1: new class SOUNDfile, with a new interface giving useful information about the file to be analysed, and calculate useful feature with subband values such as mean, rms, normalised subband energies over channels for one sample or over a whole window. Also provide an access to pcm samples. Can now virtually analyse any kind of sound file by implementing an inherited class of AllFormat, and making only few changes in SOUNDfile. No new file format support as been implemented yet! - src/mpeg: new directory containing everything useful to parse MPEG files, correspond to the old tier1 directory except the fact that MPEGfile now inherits from AllFormat. Can now start analyse of layer 3 files at any position in the file. - src/plugins: new modules implemented 2002-03-04 Silvia Pfeiffer * Version 0.2.1 Included patch from Alex Vandiver to make it work with gcc 3. 2002-03-06 Silvia Pfeiffer and Conrad Parker * Version 0.2.2 & Version 0.2.3 Some bug fixes post-release. 2002-08-19 Stefan Kudras * Version 0.2.5 src/tier2 adding smoothing filter with selectable order 2002-08-25 Stefan Kudras and Silvia Pfeiffer * Version 0.3.0 - Changed some stuff in tier1 to prepare inclusion of other compression formats (or pcm in fact) - Ported Maaate to Windows Visual C++ envrionment
