Fire on Motion

We released a new version of Audio record component.

The major update is that we update some underline audio encoders. Feel free to upgrade or try

Our audio record component can be used in web page via javascript or vbscript.

This allows developers to build online recording application by recording the audio on clients’ computer and uploading the audio file to servers. See more http://www.guangmingsoft.net/wordpress/index.php/153/record-audio-and-upload/

One question is how to deploy audio record to client’s computer. Audio record component is based on ActiveX. Tradional way is to make a CAB file so web browser can download and install it.

But nowadays, ActiveX downloading and installing is not automatical way now as IE will always prompt dilaog for user to confirm installing those ActiveX files.

So another choice is to build a setup package and ask your user to install it before doing record. Setup can be built with the free InnoSetup builder.

Yes, our Audio Record Component  supports recording multiple sources on the same PC.

Suppose you have more than one sound card installed, in order to record on the two cards simultaneously,

1. Create multiple audio record object

2. Set the correct device index and device line index.

3. Start recording of all the objects

Each record object can record its source perfectly

We add an upload method in audio record component.

Suppose  you are a website owner, you want to record your user’s voice and save to your server. Now you can do this with audio record component.

Your user can install the component on their machines, then they can record audio or speech, upload the audio. All these can be done in web browser.

We have provided a demo application in the latest release of Audio Record Component.

We just updated Active Audio Record. The features added are:

1. Play the VOX file. You can use the play object to play the raw VOX file by specifying the sample rate and channels

2. Add an event and method to record object to help advanced users to grap the content of the raw PCM wave data from sound card.

3. Some bug fixes.

Flash movie has support for Action Script which is a kind of scripting language.

But it doesn’t provide built-in audio record functionality for flash developers.

Some developers uses Zinc which extends Action Script to include more powerful functions. One of them is the support for ActiveX control. (Note, not General ActiveX Automation). This makes it possible to use Active Audio Record in Flash.

Since Active Audio Record is an ActiveX automation aerver, We have made an ActiveX Control Wrapper around it so that it can be used in Zinc. And we also provide a demo flash movie (Demo\Zinc) and its source FLA file.

Please download and try audio record in flash now.
If you want to redistribute a flash movie with audio record component now, the files needs to be redistributed are AudioCtrlWrapper.ocx, AudioCtl.dll and lame_enc.dll. And the first two needs to registered with regsvr32.exe like tools.

Our audio record object can support recording with multiple sound cards. You can do like this:

1. Create multiple audio record objects at initialization time like this. (Take VB.Net as example)

Public Class Form1
    Inherits System.Windows.Forms.Form
    Private rec As AudioCtl.CAudioRecord
    Private rec1 As AudioCtl.CAudioRecord
 
#Region ” Windows Form Designer generated code ”
    Public Sub New()
        MyBase.New()

        ‘This call is required by the Windows Form Designer.
        InitializeComponent()
        ‘Add any initialization after the InitializeComponent() call
        rec = New AudioCtl.CAudioRecord
        rec1 = New AudioCtl.CAudioRecord
        rec.SetSilenceLevel(1000)
    End Sub

2. Then the record objects can be used independently by setting the device index to different sound cards. You can record different source line for different sound cards and save the audio in different output files.
