Free Delphi and Pascal Libraries and Source Code

TurboPower Async Professional

If you need to add speech to your programs, or enable it to process speech input, TurboPower's Async Professional provides you an easy access to Microsoft's Speech API (SAPI) allowing you to integrate voice/speech recognition and speech synthesis in your programs. It also handles the sending and receiving (as well as viewing and printing) of faxes (and converts BMP, DCX, PCX and TIF files automatically), alphanumeric and text (GSM/SMS) paging, high speed file transfers (including the major file transfer protocols like Zmodem and FTP), IP telephony (audio and video, Voice Over IP or VOIP), Internet communications (Winsock access), supports ISDN modems, RS-232 and RS-485 standards, and includes an XML-based modem database. And so on. Like most of the TurboPower tools, this open source toolkit may be used with Delphi and Borland C++ Builder and ActiveX environments like Microsoft Visual C++ and Visual Basic. If you use Borland Kylix on Linux, you might want to try the TurboPower Async Professional CLX version.

TurboPower SysTools

TurboPower SysTools contain numerous utility functions and classes for Borland Delphi and Borland C++ Builder as well as programming environments that support COM objects (like Microsoft Visual Basic, Microsoft Visual C++. Among the routines included in this library are string manipulation routines, date and time math routines, high-speed sorting, high-precision maths, runtime math expression analyzer, Microsoft Excel-like finance and statistical routines, email attachment MIME encoding and decoding, reusable containers (stacks, queues, trees, deques, hash tables), CRC data integrity checking, 1 dimensional and 2 dimensional (1-D and 2-D) bar codes, money routines, logging classes, patterns, random number distributions, text data manipulation and more. SysTools is open source, released by TurboPower under the Mozilla Public License. It works on Windows systems. There is also a version of TurboPower SysTools for Kylix.

TurboPower Orpheus

TurboPower Orpheus contains over 120 VCL components such as data entry components, data entry validators, grid for presenting and editing 2 column information, status bars, progress bars, button and tab styles, report views, countdown and elapsed timer components, etc. Orpheus is open source, and may be used with development tools that support VCL such as Borland Delphi and C++Builder.

TurboPower ShellShock

ShellShock contains native VCL components that allow your application to integrate with the Windows shell and Windows explorer. Included in this package are tree views, list views, combo boxes, enumeration of folder contents, monitoring of shell events, file operations (copy, delete, move, rename, together with Windows shell animations), drag and drop support, Windows shortcut creation and inspection, customization of common dialog boxes, minimization to the system tray, etc. You need to use a development tool that supports VCL such as Borland C++Builder and Delphi to use this toolkit. ShellShock comes with source code.

TurboPower OnGuard

If you need to create demo versions of your programs, you might want to check out TurboPower's OnGuard library. The library provides you the ability to create applications that are time-limited, feature-limited, limited to a certain number of uses, limited to a certain number of concurrent network users, etc. Written in Object Pascal, it may be used in Windows development using tools like Borland C++Builder or Delphi.

TurboPower Essentials

TurboPower Essentials has 13 open source native VCL components that provides drop-down calendars and calculators, roll-up dialog boxes, 3-D labels, tiled backgrounds, scrolling messages, menu buttons, etc. You need to use a development tool that supports VCL such as Borland C++Builder and Delphi to use this toolkit.

TurboPower Visual PlanIt

Add time, task and contact management to your applications with Visual PlanIt's synchronized data-aware VCL components. You can create mult-column Outlook style contact grids; day, week, month event views, Outlook style task lists, connect-and-go database connectivity, printing, etc. The components are compatible with Delphi and C++Builder (and presumably any other development system that supports VCL components).

TMidiGen

This Delphi and C++ Builder component allows you to create MIDI sound effects and note sequences in your programs. It generates the MIDI data in memory, and thus does not require external files or resources. It has 175 instruments, Advanced Pitch Blend, Modulation, Sustain, Chorus, Reverb effects, volume and pan adjustments, etc. It appears to be free (although the website makes no mention of the licence under which it is released; let me know if you have information about this).

TToneGen

TToneGen is a Delphi and C++ Builder component that lets your application create waveform sound effects. It generates the WAV waveforms in memory. It supports amplitude modulation, full AHDSR envelope shaping to alter the dynamics of the selected waveform, handles a frequency range from 20Hz to 20kHz, etc. It appears to be free (although the website makes no mention of the licence under which it is released; let me know if you have information about this).

Soundlib2 Sound Library

SoundLib 2 is a library for mixing and playing sound files under Borland Pascal 7 and the Free Pascal Compiler with 32 bits DPMI on a SoundBlaster or compatible. It currently supports WAV, VOC, RAW, MOD, S3M and XM files. The library does automatic sample rate conversion, sample interpolation, has 32 bit mixing routines with support for a maximum of 256 channels, and support for Dolby Pro Logic. It comes with a Borland Pascal help-file and some demo files.
