Say() Function > ExportAudio.js > wav > mp3

[MrV]

If I want to export audio as either a wav or an mp3 from the symbols in Watchlist 0 for text-to-speech TTS accessibility...

How can I use Say() function to encode and create the wav or mp3 file to then export?

This is TTS-Test2.afl code

_VoiceNumber = Param("VoiceNumber",9,0,11,1);
VoiceSelect(_VoiceNumber);
//VoiceSelect(9); // Is this a persistent variable as it will not refresh for all voices when I change the number?
_Fullname = FullName();
_SayThis = "AmiBroker is really amazing software to chart " + _Fullname;
AddTextColumn(_SayThis, "_SayThis");
Say(_SayThis, purge=True);

// how can I export variable "_SayThis" from each symbol in Watchlist 0 - as an .mp3 file?
// do I have to create a .wav file and then convert that to an .mp3?
// Can this be done thru a separate .js file via ShellExecute as well? - functioning Watchlist 0 parsing code below

Here is what I have so far...
// To be placed in AmiBroker/Scripts directory
// WL0_ExportAudio.js

iWatchList = 0; // you can define watch list number here

DateObj=new Date();
D=DateObj.getDate();
M=(DateObj.getMonth()+1);
Ye=DateObj.getYear();
H=DateObj.getHours();
mi=DateObj.getMinutes();

AB = new ActiveXObject("Broker.Application");
Qty = AB.Stocks.Count;

for( i = 0; i < Qty; i++ )
{
    Stk = AB.Stocks( i );

    // exportfolder = "C:\\DataExport\\" + Stk.Ticker + ".wav";
	
	// export file name with date format = "Symbol_YYYYMMDD_HH-MM"
	//exportfolder = "C:\\DataExport\\" + Stk.Ticker + "_"+Ye+M+D+"_"+H+"-"+mi+ ".wav";  
        exportfolder = "C:\\DataExport\\" + Stk.Ticker + "_"+Ye+M+D+"_"+H+"-"+mi+ ".mp3";

    if( iWatchList < 32 )
    {
	
        if( Stk.WatchListBits & ( 1 << iWatchList ) )
        {
            AB.ActiveDocument.Name = Stk.Ticker;
            WScript.Sleep( 100 ); // 0.1 sec wait
            AB.ActiveWindow.ExportAudio( exportfolder , channels: 1, sampleRate: 16000, bitDepth: 128);
        }
    }
    else
    {
        if( Stk.WatchListBits2 & ( 1 << ( iWatchList - 32 ) ) )
        {
            AB.ActiveDocument.Name = Stk.Ticker;
            WScript.Sleep( 100 ); // 0.1 sec wait
            AB.ActiveWindow.ExportAudio( exportfolder );
        }
    }
}

//notify the user when finished
Shell = new ActiveXObject("WScript.Shell");
Shell.Popup("Audio file(s) exported to file - Done!", 10.0);

Thanks in Advance.

Say() function sends audio data to audio device directly. It does not create any files, therefore you can't save as mp3.

If you want to render text to mp3 you should use 3rd party tools.

Solution: Google for text to speech save as mp3
