Mp3 to WAV converter???

Hi all,

I would like to build a MP3 to WAV conveter. Is this possible in VB and if possible any source code would be much welcomed.

Thanks for your help

Sorry, vb jsut isn't powerful enough to do this. You'll need either c or asm for this job!

Okay thanks for the help anyway. - I just use a third party tool.

Thanks again for the quick response :).

Code:

'code from Megatron

Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As Any, ByVal uReturnLength As Long, ByVal hwndCallback As Long) As Long
                                     
Private Sub cmdRecord_Click()

    'Open a WaveAudio called Record
    mciSendString "open new type waveaudio Alias record", 0&, 0, 0
    'Start Recording
    mciSendString "record record", 0&, 0, 0
    'Play your MP3 Here.

End Sub

Private Sub cmdSave_Click()

    'Stops recording
    mciSendString "stop record", 0&, 0, 0
    'Saves the sound
    mciSendString "save record C:\Windows\Desktop\MyWav.wav", 0&, 0, 0
    'Close "Record"
    mciSendString "close record", 0&, 0, 0
                                     
End Sub

Okay thanks very much - Shall try the code a little later on.

Thnaks again

VB *is* powerful enough to do it, and not just with MCI
u can do it manually if u want - find mp3 file format and wav format and find info about recording sound.
u can do just about nething in VB; it's only limited slighly by no proper pointer implementation

Powerful enough to do anything? Ok, maybe I was wrong about VB. Maybe I didn't go deep enough. For mp3 decoding you need to block read ahead according to the bitrate. So how do you variably block read a file?

Okay thanks - Shall have a play around with some code and see if I can produce a converter.

Decided to use CD Maker 1.30 - it is great for converting MP3 to CD - I.e no decoding.

Thnaks for all your replies - This is such a great forum.

You can get the file format specification of mp3 and wav here.

Thanks again people - Sound interesting - When I get the time I shall play around - To much college work at the mo :)

Thanks again

with API calls u can do all sorts of funny file ops..
ReadFile, CreateFile
