ACM V.1.1

Welcome

The ACM.OCX is an object for Visual Basic ( 32 Bit ) and other programming tools for Windows 95 and NT 4. In this file you will find a limited Demo, that will convert 25% from a Wave file into a compress file ( like ADPCM, MP3 and any ACM codec )

Check our Web Site for more info's and updates.

( New: Audio CD writer Ocx, Audio CD reader grabber OCX... )

Audio compression and decompression Software

High compression audio files with high quality sound.

How to use in VB 5.0 !

1) Insert OCX in VB under PROJECT / COMPONENTS and a factory symbol apears in the components window

2) For the first step you can use a COMMAND button with the few lines

Private Sub Command1_Click()
Dim err

ACM.SetInputFile ("c:\PCM.wav") ' 44khz/16Bit/stereo
ACM.SetOutputFile ("c:\ADPCM.wav")

'find ADPCM codec
For i = 1 To ACM.GetNumACMs
    If ACM.GetNameACM(i) = "Microsoft IMA ADPCM CODEC" Then ACM.SelectACMDriver (i)
Next i

err = ACM.SetFormatTags(2) ' from Wave to ADPCM

err = ACM.SetFormat(8) ' 44khz/4Bit/stereo

err = ACM.Convert
End Sub

4) That's all ! Now you can use all Windows ACM compressor in your program.

5) The OCX in the root work with all Windows 95 and NT 4 version. For the ActiveX version you need a Windows update ( MFC 4.2 ).

You find a demo source for Visual Basic 5.0 SP3 in the directory VB.
