Convert WAV to WMA VB/C#/C++ Example

[Maarten]

Hi,

I just bought the dbpoweramp reference. Until now we use windows scripting host to convert from wav to wma but your application offers better control.

I'm able to convert from wav > mp3 or wma > mp3 without any problems.

When I try to convert from wav > wma I get various errors (based whether I type in : 'Windows Media Audio 9.1' or 'Windows Media Audio 9'

Error Creating WMA Profile. [clEncoder::BeginConversion]
Error: Unable to load encoder 'Windows Media Audio 9.1'. [dBCoreConverter::dBCoreConverter]

Does someone have a working code sample? (can be VB/C++/C#)

I've been playing a bit with your components, but without luck.

CREATE(DMConverter);
CREATE(DMWMASettings);


//DMWMASettings.SetWMA('Windows Media Audio 9.1', 'VBR Quality 98, 44kHz, stereo VBR', 1);
DMConverter.Convert(
'c:\temp\org.wav',
'c:\temp\converted.wma',
'Windows Media Audio 9.1',
'VBR Quality 98, 44kHz, stereo VBR',
'c:\temp\log.txt'
);

Re: Convert WAV to WMA VB/C#/C++ Example

Try:

"Windows Media Audio 9.2 Lossless"

"VBR Quality 100, 44 kHz, 2 channel 16 bit VBR"

Re: Convert WAV to WMA VB/C#/C++ Example

Hi, Thanks for your answer.

Error: Unable to load encoder 'Windows Media Audio 9.2 Lossless'. [dBCoreConverter::dBCoreConverter]

In configuration I switched to detailed error logging.
C:\Program Files\dBpoweramp\encoder\Windows Media Audio 9.2 Lossless.dll
is not found

C:\Program Files\dBpoweramp\encoder\Windows Media Audio 9.dll
is there.

Now when I set back the option back to 'Windows Media Audio 9'
Error Creating WMA Profile. [clEncoder::BeginConversion]

I tried to play with the options:

'VBR Quality 25, 44kHz, stereo VBR'
'' (EMPTY)
'1' --> to try for an option
'VBR Quality 100, 44 kHz, 2 channel 16 bit VBR'

But no luck either.

Can I call some code to verify available profiles to the application?
Or is this info available in some registry key?

Dear,

Through comment line I get the same error

Will look on google as well

"c:\program files\dbpoweramp\coreconverter.exe" -infile="c:\temp\org.wav" -outfile="c:\temp\converted.wma" -convert_to="Windows Media Audio 9" -codec="Windows Media Audio 9" -settings="VBR Quality 98, 44 kHz, stereo VBR" -vbr

Re: Convert WAV to WMA VB/C#/C++ Example

I managed to get this command-line working:

"E:\program files\dbpoweramp\coreconverter.exe" -infile="E:\test.m4a" -outfile="E:\test.wma" -convert_to="Windows Media Audio 10" -codec="Windows Media Audio 9.2" -settings="VBR Quality 98, 44 kHz, stereo VBR" -vbr

Note I'm using WMA 10, not WMA 9.

However, I'm having trouble with the scripting equivalent also. Trying this, which would seem to be what I want:

Call dMC.Convert("E:\test.m4a", "E:\test.wma", "Windows Media Audio 10",   -codec="Windows Media Audio 9.2" -settings="VBR Quality 98, 44 kHz, stereo VBR", "E:\error.txt")

gives a Windows Scripting Host error:
Type mismatch: '[string: "Windows Media Audio "]'.

Other various permutations end up giving me the error in my error log: "Error Creating WMA Profile. [clEncoder::BeginConversion]"
The line that gave me that error is:

Call dMC.Convert("E:\test.m4a", "E:\test.wma", "Windows Media Audio 10",   "VBR Quality 98, 44 kHz, stereo VBR", "E:\error.txt")

More ideas, anyone?

Re: Convert WAV to WMA VB/C#/C++ Example

Hi,

Thanks for all your comments!

I've command line working as well.

I noticed some other topic on the form where someone replaced the

"VBR Quality 98, 44 kHz, stereo VBR" -vbr
{qt}VBR Quality 98, 44 kHz, stereo VBR{qt} -vbr

What we could check is:

1. command line works; so profiles are valid
2. what does the dmConverterreceive?

- does my application send correct ascii code to the converter --> the reason why we put in xml '&amp' instead of '&'????

- is there a way (debugging option) to see what is actually received by the external dBpoweramp application?

- I noticed: ' -vbr' <-- a space!! could this be the problem????

:-) getting closer:

DMConverter.Convert(

'c:\temp\converted.wma',
Compression,
' ' + '-vbr does' + 'text' + 'come' + 'here',
'c:\temp\log.txt'

RESULTS IN ERROR

Re: Convert WAV to WMA VB/C#/C++ Example

'xxx' + '-vbr' + 'VBR Quality 98, 44 kHz, stereo VBR',

OR

'xxx -vbr' + 'VBR Quality 98, 44 kHz, stereo VBR',

RESULTS IN DEBUGGER
Converting to 'c:\temp\converted.wma' encoder settings ' -vbrVBR="Quality"'
Converting to 'c:\temp\converted.wma' encoder settings ' -vbrVBR="Quality"'

somehow it completely misses all information which is send.

:-( let's try to add it to some other line of code...

Re: Convert WAV to WMA VB/C#/C++ Example

SOLVED :D

DMConverter.Convert(
'c:\temp\org.wav',
'c:\temp\converted.wma',
Compression,
'-codec="Windows Media Audio 9.1" -settings="VBR Quality 98, 44 kHz, stereo VBR" -vbr',
'c:\temp\log.txt'
);

When you put all information about the profile in one big string.. then it's working..

please can someone add this to the standard help page (rewrite to vb./c#/c++ if he likes)

would save a lot of time since there is no simple example on * > wma conversion.

Re: Convert WAV to WMA VB/C#/C++ Example

For vbs scripting, since single-quotes are comment marks, you have to use chr(34) to make double-quotes appear in the string. So my example looks like:
Call dMC.Convert("E:\test.m4a",
"E:\test.wma",
"Windows Media Audio 10",
"-codec="+chr(34)+"Windows Media Audio 9.2"+chr(34)+" -settings="+chr(34)+"VBR Quality 98, 44 kHz, stereo VBR"+chr(34)+" -vbr",
"E:\error.txt")
