CLAM CHANGELOG

2010-??-?? CLAM 1.4.1 SVN $Revision: 15090 $

• NetworkPlayers and backends
• Network backends for plugins are NetworkPlayers now
• Common Backend code to inspect the network moved to base NetworkPlayer
• ControlSources and ControlSinks with multiple controls
• New LV2 backend:
• CLAM builds LV2 plugins from networks (see wiki tutorials)
• Helper scripts to automatically generate lv2 rdf's
• OfflinePlayer accepts a control sequence script, containing in each line: SMPTE controlSourceName and value.
• Infrastructure:
• Network added a GetProcessingName interface
• Network flow control orders port-less processings (control-based sources, sinks and filters) using its y-position. Reasoning: make the order predictable
• Dependencies:
• xerces-c 2.8 -> xerces-c 3.0 (requires pkg-config file)
• Removed some deprecated symbols
• enum EFFTType
• Untemplatized ComplexTmpl/PolarTmpl -> Complex/Polar
• Bug fixes:
• InControls are initialized to the default value of the control type (0 for numerics), this could change the behaviour (previously undefined)
• Ports and Controls enhancements:
• TypedIn/OutControl from deprecated to obsolete
• Added In/OutControl/PortBase::SetName to be able to change the name of a connection without disconnecting it.
• Base classes Storage and XMLable are no more. Just XML kind of storage.
• New plugins:
• expression: Tranforms float control values using functions in C-like syntax.
• timeDomainEffects: DopplerEffect, Flanger and more
• DynamicType clean up:
• Generic handling of optional DT attributes AddAttribute(i) and RemoveAttribute(i)
• A lot of internal simplification (more needed)
• New way of calling DynamicType constructor relying on the output of static methods
• Fields information is available without instantiating an object
• Shared and Shallow copies no more supported (until requested again)
• Removed isPtr flag for fields types (always false).
• Removed offset precomputation for preallocated mode
• New generic accessors: AddAttribute(i), RemoveAttribute(i), HasAttribute(i)
• ExistsAttr(i) removed in favor of HasAttribute(i)
• Removed macro generated GetTypeX, GetSizeX, GetIdX
• Removed unused protected methods which exposed implementation too much: Get/SetData, GetNumActiveAttr, GetDynamicTable, GetTypeDescTable, GetDataSize, Get/SetOwnsItsMemory
• Examples:
• TickExtractor fixed assert failures when using in controls as out controls
• TickExtractor now depends on libsamplerate instead of the ancient unavailable libresample 0.13 that had to be included in the sources.

2010-03-05 CLAM 1.4.0

'3D molluscs in the space release'

• SVN Revision: 14035
• New controls:
• Typed controls: Controls with other type than floats.
• Regular in controls have callback (deprecates InControlTmpl)
• Example processings using boolean and MIDI controls
• MIDI module handling MIDIMessage controls
• Processing type metadata:
• Icons
• Relations to a token type as sink, source or monitor
• Relations to a control type as sink, source, sender or display
• Binary (executable or library) where the processing is defined in.
• Rich data types: although you can use any C++ data type as data token or control without explicit declaring it, you can add properties, such as connector color or a display name by defining a ProcessingDataPlugin.
• NetworkPlayers (backends):
• Pause state: not playing the network but feeding silence to the backend
• Multiport sources and sinks supported
• Buffer audio sources and sinks (vs. stream audio, which is still available)
• Common implementation factored out to the base class
• Plugins (Ladspa, Vst, Lv2) became NetworkPlayers
• LadspaNetworkPlayer (former LadspaPlugin):
• Now it is a Network Player
• Supports variable frame size (avoid clicks in ardour)
• When network processings support variable audio size it avoids buffering and copies
• ControlSources parameters can be maped to LADSPA hints within LADSPA limitations
• Ladspa hosted plugins have a buffer based version (vs, stream, avoiding copies)
• examples/Plugins/Lv2PluginExample: New experimental network player for LV2
• examples/Plugins/VstPluginExample: Added primitive support for Qt interfaces
• Processing::Get{In,Out}{Control,Port}() overloaded for indexes and names.
• Processing::GetN{In,Out}{Controls,Ports}() to get the number of connectors.
• Processing::Get{In,Out}{Controls,Ports}() are now protected methods.

• Added a new CLAM_EMBEDDED_FILE version for mingw
• Audio File:
• AudioFileIO implementation simplified, API documented
• MonoAudioFileReader supports seeking
• Experimental sndfile plugin, suporting seeking and lockfree file reading.
• FIX: sndfileplayer didn't loop and stopped sending position control.
• clamrefactor.py: a tool that eases batch upgrading many clam networks when you rename a processing, port, control, configuration parameter... also useful to cleanly change configuration parameters directly on the xml.
• Added 'intel-optimize' option to optimize for intel architectures
• Build system: native plugins are now built as regular libraries (with installable headers) plus an empty plugin library that just links against them. This enables having interdependencies, or explicitly use symbols defined in a plugin.
• plugins/spatialization:
• Global doxygenation
• Vbap3D: 3D panning on whatever 3D speaker layout
• New scripts (xyz2ea and ea2xyz) to convert layout files

• CrossCorrelation: Computes the cross-correlation of two audios on spectral domain
• ...many others not included here, check the doxygen for the module.
• plugins/filters:
• Filter processing: Direct form implementation of the linear, time-invariant difference equation. The same form of the 'filter' function of common numerical computation programs
• Adaptative notch filter as an implementation of the steepest descent algorithm

• Realtime simple statistical properties calculation (mean, standard deviation, min, max)
• plugins/effects:
• TimeDelay with a wet/dry control
• Clipping processing (clips the input signal to -1..1 range or whatever input control says)
• AudioNormalization processing: Normalizes the input to -1..1 range checking for the max
• Resampler plugin variant: Resampler by sample-rate ratio. Iterpolation options. Useful for upsampling and downsampling by factors (x2, etc)

'Prototyper with streaming SMS transformations'

• SMS Transformations on the network editor:
  • All SMS Transformations have been refactored in order to work in streaming mode and not only in offline mode.
• New Prototyping way:
  • Prototyper: Allows to bind a Qt desinger interface to a Network XML definition so you can have an CLAM GUI application up an running without a single line of code. Current features:
    • It uses the widget names and classes to Automagically relate widgets to processings, ports and controls.

  • Shortcut CLAM::ConnectPorts with either ports numbers and names
  • Shortcut CLAM::ConnectControls with either control numbers and names
  • Underlying data structure for streaming tokens is specified using a Template-Policy
    • Default policy is PhantomBuffer: an contiguous-memory circular buffer with some nice feature
    • But also usable any STL container
  • Internal (implementation) classes hierarchie has been simplified a lot.
  • Thoroughly (unit) tested, and stress tested
  • Stream class now can be policy-templatized to PhantomBuffer or any STL container
  • New ports-linking schema : only out->in (and not out->data or in->data)
    • Ports Attach(ProcessingData&) method has been deprecated.
    • Please refer to the migration guide and doxygen docs
  • New AudioIn/OutPorts. Similar tor In/OutPort but with richer interface
  • New feature: In/OutPortPublisher
    • A composite port that "publishes" one or more inner ports.
    • When linking a port with a publisher it acts like a mediator for its published ports.
  • New In/OutPort public interface
    • Constructors. Now gets only two parameters, and not the window size anymore
    • Size and Hop getters and setters, GetData, Consume, Produce, CanConsume, CanProduce, etc.
• SMSAnalysis-Synthesis In Streaming:
  • Till this release SMSAnalysis and SMSSynthesis needed a Segment as intermediate data now they can also use ports to process in streaming
• NetworkEditor:
  • Added SMSAnalysis and SMSSynthesis in the processings factory. But still some problemes needs to be sorted out.
• AudioFile IO:
  • AudioFile have easier and clearer interface:
    • AudioFile::SetHeader is obsolete
    • AudioFile::SetLocation is obsolete, instead use:
    • AudioFile::OpenExisting
    • AudioFile::CreateNew
• Processing Interface Clean up:
  • Removed Processing inheritance from Component
  • Processing::FlattenObjects removed until needed
  • Processing::SetPrototypes/UnsetPrototypes removed until needed
  • Processing::MayDisableExecution removed until needed
  • Processing::DisableExecution removed until needed
  • Processing::LostData removed until needed

  • Processing::composite_begin/end moved to the ProcessingComposite
• Low Level Descriptors Revision (Audio, Spectral and SpectralPeaks):
  • Full doxygen documentation.
  • Formulas revised and corrected.
  • Most NaN singularities has ben solved. Check doxygen.
  • Unit testing and back-to-back testing for every descriptor.
  • Asserts that source data is in linear format
  • SpectralDesc Skew/Kurstosis -> MagnitudeSkew MagnitudeKurtosis
  • Spectral and Harmonic Tilts removed (Returned very unstable values)
• Beta Qt Plots:
  • Audio (playable).
  • Fundamental (playable).

  • Note that these widgets are in the initial development phase.
  • Extra requirements: qwt library.
• Standard:
  • FormatData.hxx removed, also their useless uses
  • Vector removed

  • Infrastructure for reading basic Data (wav,xml)
  • Back to back testing infrastructure
  • Improvements to the python script to run all tests and apps
• Doxygen documentation:
  • XML documentation modules added.
  • Documentation module on Configurators: Autogenerated Qt/Fltk dialogs to edit DynamicTypes.
  • More scatered changes and fixes.
• Build System:
  • Full rewrite of configure.ac. configure.ac is now generated from a perl-script which does a lot of code-reuse to create a consistent and uniform configure.ac.
  • configure generates HAS_ values (in packages.cfg), which is used by srcdeps to make sure USE_ and HAS_ is consistent. Using USE_=$(HAS_ in settings.cfg can be used to make usage conditional. On windows the user should make sure that the build/packages-win.cfg file is reflecting his system
  • configure has a new way to present the user with the possibity to disable the use of specific libraries. If the user does not have a specific library, it can tell configure not to use it. The generate HAS_ value will be false, and if a settings.cfg tries to use it, srcdeps will notice it. This allows to compile certain examples that don't use libraries you don't have.
• MS Visual support:
  • MS Visual 6 is no longer supported.

2004-04-13 CLAM 0.6_1

2004-01-12 CLAM 0.5_6

'XML and Ladspa rewrite'

• XML:
  • Both, basic XMLStorage usage interface and customization interface have changed. Check 'Migration Guidelines' on the documentation and update your code.
  • Ported to XercesC 2.3. Library dependant code is more isolated and structured so libxml or expat ports will be easy.

  • One statement calls using static methods XMLStorage::Dump and XMLStorage::Restore
  • Trapable error notification using exceptions.
  • API Change: XMLStorage::Store and XMLStorage::Load receives a const-ref and a ref to adapters instead a pointer
  • API Change: Component::StoreOn is now a const method.
  • Scoped XML: [Experimental] allows (write only) fast XML generation without having to define CLAM data.
  • Cppunit Tested and general code clean up
• Network Editor:
  • Smarter conections display (control conection with vertical tangent and that wires always goes outward the processing)
  • Refactoring of the application structure.
  • Bug fixing.
  • Created Unit Tests for the entire application.
• Processing Objects:
  • GetName has been removed from all CLAM processing configurations because it was not really useful.
  • Simplified Processing interface related to ports and controls.
• Error handling:
  • Failed assertions dump a backtrace in GNU/Linux.
• SMSTools:
  • Fix: SDIF storage was unconfigured on release mode.

2003-11-06 CLAM 0.5.4

• Build system:
  • Added 'Compiling_against_CLAM_example' subdir to the build dir. It contains an out-of-the-box example of how a CLAM external aplication can compile against the library. It contains a tutorial in its 'readme.html' file. Since now it was a separated tarball available in the web. Now integrated in the CLAM dir tree.
  • Configuration:
    • Use fltk-config to get the paths to fltk includes/paths
    • QTDIR support
  • Added rules to pre-process headers with moc (QT)
  • Add .dsp files for many CLAM programs

    • Don't look through xerces include directories recursively
    • Performance improvements
    • Bugfixes
    • Generate from empty dsp
• Standard/Misc:
  • Text: Added to the standard as substitution for std::string on those case when we need multiword strings on XML. (XML loads only one word for std::strings)
  • BPF: Modified BPFTmpl<>::Insert() (both overloads) to return the index at which the element was actually inserted (i.e. the inserted element's index).
  • CLAMMath: Fixed a bug in Round() and Chop() which caused the fpu control word to be changed when calling these functions (but only in debug build).
  • Moved some includes from hxx's to cxx's and doing forward decl to improve compilation speed
  • Working towards supporting MacOSX/PPC (including byte order issues)
  • Added a FileMIDIDevice
  • SoundFileIO improvements ( support for more sample formats added, better errors)
  • Declare template specializations in header inline ( gcc 3.x compatibility issue )
• ProcessingData:
  • SpectralPeakArray ProcessingData; when adding an IndexArray to an already existing SpectralPeakArray and calling InitIndices(), the IndexArray would be allocated to the actual number of elements in the other arrays, not their allocated size (i.e. the maximum elements they can hold without reallocating).
  • Fundamental ProcessingData; removed two Dynamic Type attributes which were used to keep track of the size and allocated size (max size) of the Fundamental. These values are now derived from either of the arrays (freq/err). Also calling SetnCandidates() or SetnMaxCandidates() now actually affects the arrays instead of merely setting the size fields. This is more consistent with SpectralPeakArray for instance.
  • Audio ProcessingData: bug fixed in GetAudioChunk method that left extracted chunks with uninitialized Sample Rate and Begin Time
  • Spectrum Conversions: Added a method called Complex2LogMagPhase() which efficiently converts a complex spectrum to a log. magnitude (i.e. in dB's)/phase spectrum.

    • Editor widget layout tweaked a bit to make bigger the screen area devoted to transformation parameters edition

2003-07-03 CLAM 0.5.1

'SMSTools update and Mac compilation issues'

2003-06-11 CLAM 0.5.0

'flashing new build system and SMSTools'

• Build system:
  • New flashing build system, fast, crossplatform and easy to use
  • Configuration file for each binary is shared between platforms
  • Automatic detection of binaries dependencies
  • Automatic generation of dsp's and make dependencies
  • See the documentation for more details
  • Depends on FLTK 1.1.3 instead 1.0.X
• Processing - All:
  • Concreteconfigure should asserts false instead throwing bad_cast exceptions when a wrong type of configuration is provided.
  • Provided a helper template function 'CopyAsConcreteConfig()' to be used in ConcreteConfigure instead using slow dynamic_cast's.
  • Most Processing in CLAM adapted to use 'CopyAsConcreteConfig'.
• Processing - Generator:
  • Oscillator had a heavy compilation dependency since it used AudioManager for initializing sample-rate. Now it doesn't (uses 44100 as default)
• Processing - Analysis and Synthesis:
  • SMSAnalysis uses a StreamBuffer with one write region and two read regions
  • SpectralAnalysis does not have an internal CircularBuffer anymore
  • SpectralSynthesis does not have OverlapAdd as an internal Processing anymore
  • Now SMSSynthesis has three OverlapAdd Processings for each component: global, sinusoidal and residual.
  • OverlapAdd now uses a StreamBuffer with one WriteRegion, one AddRegion and one ReadRegion.
  • CleanTracks is much more faster, (and then usable)
• Flow - Network & FlowControl:
  • New Network and FlowControls classes that works quite together: Network manages processings ownership, nodes, gives simple interface for stablishing processing topologies. FlowControls gets the topology from the associated network and does its processing-firing scheadule. The scheaduling algorithm is reimplementable now we have a pull-scheadule implementation
  • Limitation: only tested for fixed buffer size.
• Flow - Nodes:
  • New pure virtual interface for attaching ports and traversing processings
  • Some refactoring simplifying checking logic. Further refactoring in progress
  • A new AddStreamRegion has been introduced (used for overlap and add).
  • StreamRegions can be now used using center position logic.
  • StreamRegions belonging to a StreamBuffer are now automatically initialized so the center time is zero and the first half of the biggest read region is already written with zeros.
  • Limitation: Do using ports (supervised mode) only tested with fixed size buffers.
• Factory:
  • Added a general purpose factory which is templatized by the abstract product (returned type). Nested class Registrator helps registering concrete classes to the factory.
• Standard:
  • Added the Filename type to be used in configurations instead of std::string. Configurators detect them and use a suited widget.
  • Flags: Flags derived classes should define the copy constructors explicitly. One parameter template constructors is not enough (it never was)
  • Array: debugged the copy constructor when array does not own memory and introduced a CopyChunk method, similar to GiveChunk but with memory copying.
• DynamicTypes:
  • Fix: Definition of DynamicTypes on foreign namespaces leaded to compilation problems if you don't use the ugly 'using namespace CLAM;'.
  • Fix: dynamic type self-assignation doesn't modify the object.
• Examples - SMS (old AnalysisSynthesisExample):
  • FlowControlExamples. Gives examples of use of networks and flow-control.
  • Renamed as SMS. GUI is now SMSTools.
  • Applies chained SMS transformations
  • Menu reorganization
  • New views: sinusoidal tracks, spectrum & peaks
  • Frame navigator
  • Fixes and performance enhancements
• Examples - Other:
  • Fix: The Tutorial4 didn't compile (used Complex in an old fashioned way).
• XML:
  • New method XMLStorage::UseIndentation to enable pretty XML formatting
  • Obsoleted constructor receiving the root tag as parameter
  • Obsoleted _restoreFrom and dumpOn, use Dump and Restore instead
• Visualization Module:
  • Major rework in several areas:
• View concept has now been mapped into two different classes, ModelAdapter's whose mission is to wrap Core CLAM objects so they can have Visualization Module components attached, and ModelController's whose mission consists in allowing Visualization Module components to be controlled indirectly by the user from the GUI. From now on VM interface will be kept stable ( at least until CLAM 1.0 )
• Presentation semantics are preserved, but their nature of widgets is emphasized in several ways
• Several new graphic representations of DSP concepts such as the sinusoidal tracks
• OpenGL data renderers optimized and debugged
• Old CbLib interface deprecated in favor of libSigSlot, CLAM own implementation of the C++ idiom of Signals & Slots
• New plot's substitute the functionality offered by old snapshots
• Most of VM code is now documented with Doxygen comments
• Several new FLTK widgets, such as the Fl_Axis, Fl_SmartTile, etc.
  • Configurators: New type suported: 'Filename'
  • 'Formal' documentation will be soon made publicly available
