How to convert WAV to FLAC

[FLACConverter]

Hi!

I have this problem, that I don't know how to convert my recorded Wave into FLAC format. Is there any way I can do it easily?

Not sure if this a spam bot, where the the next reply will be with a link to some commerical software that has a trial.

In either case one of the first links was Xrecode

It looks like they have a portable version (so no installer needed) and it works with the command line.

That's the quick and dirty solution.  There is probably a better one using some .Net/ActiveX product

I have been probably misunderstood. I need to do this in my app in LabVIEW, so it would be great if someone had some .dll's that are know to work with LV and that I can use in my VI. A site with well described coding algorithm would be ok too (even better because I could make the encoding myself). 🙂 Though thank You for help. 🙂

Why reinvent the wheel?  If someone has a commandline program that will do the converting, why not call that program from the commandline using LabVIEW?

He's probably unaware that you can do this.

OP, use System Exec.vi to call the aforementioned tool from cmd line.

I'm trying to use the System Exec, but i get a quite annoying error:

C:\Programs is not recognized as an internal or external command, operable program or batch file.

While I try to use command:

C:\Users\xxxxx\Documents\LabView Projects\flac.exe -f abc.wav

I also got this VorbisEnc.dll for FLAC encoding, but I have no idea how to use the .NET connectivity tools to use it (or maybe else - I don't know what arguments should I pass to the dll to get the conversion). Anyone has some experience with stuff like this?

The flac.exe was downloaded from here:

http://sourceforge.net/projects/flac/files/flac-win/flac-1.2.1-win/

Thank You for help in advance!

Put the command in quotes.

Already tried it in many different options... Still nothing.

The thing I don't get most, is why it's referencing to directory C:\Programs while I do not refer to it in any means. The message with the error is written in the standard error field. At the NI offcial help I found that it's something with 32 and 64 bit apps but it doesn't work for me because my exe is not a system one... Maybe I'm doing something wrong...

Post the VI you're trying to run... you're probably just hitting a syntax error.

I've deleted some stuff from string inputs just not to pass my personal directories... 🙂
