New features in version 3.0 (June 2007):

• Updated to support Delphi 2007 and C++Builder 2007.
• Support for TeeChart 8.
• Support for update Intel IPP v5.2 and consequently Core 2 Duo optimized.
• HtmlHelp 2 format support added. Now F1 finally works again from code and components in D2007.
• All code examples now also have C++ examples.
• All code examples in the help have been recreated with support for Vector/Matrix expressions. (See MtxVec v3 new syntax options.)
• Demo updated with Vector/Matrix syntax.
• New C++Builder translation of the DSP Master demo.
• New set (hundreds) of true color 24x24 and 16x16 icons for components to support newer IDE tool palette.
• Many minor enhancements and bug fixes.

New features in version 2.1 (May 2006):

• Several new signal processing components.
• Further enhanced design of the streaming pipes

New features in version 2.1 (December 2005):

• Superfast arbitrary factor rate converter component tested and certified.
• TSignalBuffer component had some bugs fixed.
• TSignal.Pull methods are completely rewritten. It is now possible to build much more complex processing pipes with much less code.
• Fixed a bug in Complex Cepstrum, which occured during transition to .NET
• TSignalChart and TSpectrumChart now accept multiple inputs. Same component can be connected to the same chart more than once or to multiple charts at the same time with centralized redraw control.
• TSignalRead.RecordPosition now calls TSignal.Update.
• Fixed a bug with TSignalIn for mono signal recordings.
• Fixed onStart and OnStop events for the TSignalIn and TSignalOut.
• Fixed the Report generation for TSpectrumAnalyzer and others.Report interface has also changed to support .NET.
• Fixed Logarithmic property for TSpectrumAnalyzer. It is now possible to toggle between logarithmic and linear scale for averaged spectrums.without the need to perform the averaging again.
• Fixed a bug for TSignalGeneratorDialog where it did not store the changes made.
• TAnalysisList now has a Continuous property.
• Reset method has been added to all filtering components, and allows delay lines to be reset to zero.

Changes v2.0 (march 2005):

• Arbitrary FFT length for 1D and 2D transforms.
• Support for SSE3 instruction set.
• Intel SPL interface replaced with support for IPP library.
• Substantial increase in number of optimized primitive functions and methods via MtxVec v2.
• Many new "multi-channel" list components.
• Improved TSignalFile with several new properties.
• Support for .NET
• New TSignalStoreBuffer component.
• New TSignalEnvelopeDetector component.
• New connection mechanism for TSpectrumChart and TSignalChart.
• TSignalRead component editor.
• Minor bug fixes.
• Improved piping mechanism for data streaming.
• Substantially improved range checking and programmer safety.
• Support for TeeChart v7.x

Changes v1.1 (January 2004)

• Minor changes were made to TCrossSpectrumAnalyzer to allow access to the complex version of the transfer function.
• TSignalRead now has support for Audio Compression Manager and can read any audio file format supported by installed codecs. (Currently only the .wav extension is supported).
• SignalRead, TSignalWrite, TSignalIn, TSignalOut now support TWaveFormatExtensible. This enables recording and playback of 24-bit and 32-bit audio files with high sampling frequencies (24bit/192kHz).
• TSignalRateConverter, converts sampling frequency by any rational factor at top notch speed while retaining linear phase. Achieves 180dB SNR. Can be used in real time as a premixer stage.
• TSignalReadDialog, TSignalInDialog, TSignalOutDialog have new user user dialogs.
• Improved help file
