Previous pageReturn to chapter overviewNext page

First of all let us say that if this guide should not be clear to you, feel free to contact our support team for any doubt or curiosity you may have: we usually answer all of our customers questions in less than 24 hours. Note that the purpose of this guide is to give a taste of the main features available inside Active Sound Recorder.

 

As an integration to this guide, several examples of use of this component, in Visual Basic 6 and Visual C++ 6 languages, can be found inside the "Samples" folder: if during the setup phase you left the installation directory to its default, you will find them inside "C:\Program Files\Active Sound Recorder\Samples".

 

The first needed step is to add the control to your project: see the Adding the control to a project section for details.

 

Main features provided by this control are the following:

 

Recording from an input device, usually defined as "sound card": see the How to perform a recording session section for further details.
Recording from other sources like sound files on disk or from an Internet URL: see the How to record from files, memory or clipboard and the How to perform an Internet-based recording session sections for further details.
Ripping CD tracks: see the How to perform a CD ripping session section for further details.

 

An important topic to keep count of is how synchronization between the container application and events generated by this control works: see the How to synchronize the container application with the control tutorial for further details.

 

Further capabilities of the control, not directly related to sound recording, are the following:

 

the ExtractAudioFromVideoFile method allows extracting the audio track from a video clip and to store it inside an output sound file that may be used later for further editing.
Control of the volume through mixers: usually every sound card have a mixer which can be used in order to set the card volumes; you can access these information using the following methods:

 

MixerGetCount to get the number of mixers currently installed: usually one mixer is available for every installed sound card.

MixerGetDesc to retrieve a friendly description of a mixer.

MixerVolumeSet/MixerVolumeGet to set/get the volume of a system mixer

MixerMuteSet/MixerMuteGet to set/get the mute state of a system mixer

 

When dealing with Windows Vista and higher versions, mixers can be managed more easily through the usage of the CoreAudioDevices object: see the How to access settings of audio devices in Windows Vista and later versions tutorial for further information about this feature.
