AboutAudioLab
What can I build with AudioLab?
With AudioLab you can do just about anything imaginable: synthesize, capture, process, and analyze; mix, listen, visualize and more.
Applications include:
- Audio recording/playback.
- Audio converters/re-encoders.
- Jukeboxes, and Play Lists.
- Audio broadcasting.
- Connecting to audio streams.
- Audio Editing, and analysis.
Supports ASIO and VST 2.X and VST3
“Audio Stream Input/Output (ASIO) is a computer sound card driver protocol for digital audio specified by Steinberg, providing a low-latency and high fidelity interface between a software application and a computer’s sound card.” (See steinberg.net. Quote from wikipedia.)
“Steinberg’s Virtual Studio Technology (VST) is an interface for integrating software audio synthesizer and effect plugins with audio editors and hard-disk recording systems.” ( See steinberg.net. Quote from wikipedia.)
“
VST3 marks an important milestone in audio technology with a completely rewritten code base providing not only many new features but also the most stable and reliable VST platform ever.” ( See steinberg.net. )
Play recorded audio (see .NET or VCL tutorial):
Capture and record audio (see .NET or VCL tutorial):
Capture, process and record audio:
Play or capture, analyze the audio, and display the results:
Mix different audio sources, record and listen to the result:
The latest version of AudioLab supports the older Win32 API ( WaveAPI, Audio ACM ), the newer DirectShow and DMO; and allows, if needed, any mixture of these technologies. The developer can choose the technology and can switch from one to the other at any moment: AudioLab hides the complexity of the chosen technology and makes the components look almost identical from the developer’s perspective.
Here is the full list of the supported technologies:
Win32 API:
- Audio Compression Manager ( ACM )
- WaveAPI
DirectX:
- DirectShow
- Direct Media Objects ( DMO )
Intel:
- Intel MMX
- Intel Performance Primitives ( IPP )
The library includes Wave Player, Wave Logger with compression capabilities, DirectShow Audio Player and Audio Logger, Signal and Noise generators, graphic equalizer, audio mixer, multiplier, convertors, spectrum component, channel splitter and merger, a Win32 API and DirectShow Audio Capture components, a Win32 API and DirectShow Audio Playback components. Three additional components from the SignalLab have been added to allow processing Spectrum Data.
Our component libraries come in 3 versions a VCL – Firemonkey version (for Delphi / C++ Builder / RAD Studio XE4 to 10.1 Berlin), an MFC compatible Visual C++ version, and a .NET 2.0 and 4.0 (4.5 and 4.6 compatible) supporting Visual Studio 2005 to 2015.
The RAD Studio version is a set of native VCL and Firemonkey components of which all include now the powerful Mitov Runtime.
The Visual C++ version is a set of native Visual C++ classes (components).
The NET 2.0 and 4.0 (4.5 and 4.6 compatible) version is a set of managed .NET components. The .NET version has the same performance as the native versions, and supports all the Microsoft .NET languages including Visual Basic, C#, J#, F# and C++/CLI.
Due to the unique architecture of the OpenWire platform, the components are implemented the same way in Managed .NET and native Windows (32 and 64 bit) environments. The code to control a component from VB.NET, C++/CLI, C#, and J#, Visual C++ MFC, Delphi, and C++ Builder is almost identical. This allows the developers to migrate and share code between the different environments thus significantly improving the productivity.
OpenWire Libraries: for fast, complex data stream processing with almost zero lines of code!

OPENWIRE FREQUENTLY ASKED QUESTIONS
Does AudioLab support the format of my Audio Files?
AudioLab supports both Win32 API and DirectShow technologies. Win32 API will allow you to play only Wave files. If you decide to use DirectShow AudioLab will use any DirectShow filter available on your system. If you have a DirectShow filter for a particular video format AudioLab will recognize the format and use the proper filter. This means that AudioLab is capable of using any format available today. If you have a file that you can’t play in AudioLab, it means that you probably don’t have the proper DirectShow filter. Please search the web and download the filter needed for the particular format.
I can’t play my video file! What is wrong?
In order to play format other then basic Wave you must use the DirectShow TVLDSAudioPlayer component. If you still can’t play the file, please check if you have installed a DirectShow codec for the file format. AudioLab needs a codec available in the system in order to decode the file. A huge selection of codecs is available on the WEB.
Do I have to purchase AudioLab?
AudioLab is free for non commercial purposes. This means that you can use it for personal pleasure, hobby, or evaluation purposes. If you are student you can also use it for free for your educational needs including school projects. If you are a tutor at present you also can use it for free for your classes. However in the near future a low cost tutor license will be available, and you will have to purchase it. Your students however will not need license to use the product at class.
Is AudioLab multithreading? Will it stop streaming while I move the window with the mouse?
Yes. AudioLab is fully multithreaded and will not stop streaming while the main thread is busy.
Does AudioLab support DirectShow?
Yes. AudioLab supports DirectShow 8.1 or higher.
What version of DirectShow I need to run AudioLab?
AudioLab supports DirectShow 8.1 or higher.
Can I capture and save audio sample out of the audio stream?
Yes. Use the TALGenericFilter to obtain the sample. Check the CustomFiltersDemo example in the demos directory.
Can I create a audio on the fly?
Yes. Use the TALGenericFilter to generate the buffers. Check the “Quick Start” manual for more information.
Can I process the audio faster than the normal audio speed.
Yes. Check the “Quick Start” manual for more information.
I want to copy and paste parts of the audio a new file. Can AudioLab do that?
Yes. AudioLab uses DirectShow to play and record files. Many formats do not allow easy positioning and can’t be used with DirectShow Editing Services. AudioLab offers a different approach. It allows you to play even non seek enabled file to a specific position and copy a portion of the file into a new one. Check the “Quick Start” manual for more information.
I want to use AudioLab. Do I have to install DirectShow?
Yes. Check the “DirectShow is not required on your system if you are not planning to write application using the DirectShow components of the package.
Can I play audio files from a Web URL?
Yes. You can use the TALDSAudioPlayer to play files as well as any audio URL from the web.
