Vox To Wav Converter
Hi,
I have to develop a Voice Logger for which I need to convert a Vox file to Wav file. There are such programs available on net but most of them are standalone applications with a user interface. I want to write a program to do this conversion. Can anyone tell me where i can find source code (program) that does this conversion or else an algorithm with the help of which I can write the program.
Thanks and regards,
Gunjan Mishra.

Here is some code, in an Intel's web page (in C):

Thanks for the reply.
I have explored this link before and the vox to wav conversion using this file/exe was ineffective. All I could hear after the conversion was "noise". There are various sampling rates and compression ratios that are used while creating Vox files and the C file in this link does not specify as to which type of Vox file can be converted through this exe.
Is there any other website where I can get help on this?

Hi Gunjan,
I'm wondering if you found what you needed, because I'm looking for a way to play a vox file (uLaw,8000 mono) through the computer's speakers rather than over the phone line.
Thanks!

Re: Vox To Wav Converter
It is going to take more information to properly help you. Like where did the vox file come from. It is ADPCM or compressed using alaw , ulaw ?
There are a multitude of different options for compression of vox files and you would have to use that specific decompression to be able to get proper output, ie. Dialogic ADPCM and Brooktrout ADPCM are different in their bit structutres.
if you can provide more info about the source vox file I might be able to help you.

Re: Vox To Wav Converter
Thanks Liqdfire,
I'm using Dialogic, I don't think it's ADPCM. When I use a program like GoldWave to open it, I have to specify ulaw, sampling rate 8000, mono.
Thanks for any help you can give.

What language are you using ??
I might have an example for you on decoding mulaw in c++

Ok here is the sample source code from the book "A Programmer's Guide To Sound" written by Tim Kientzle published by Addison-Wesley

muLaw is the same a uLaw. It looks like a U but it pronounced mu

Re: Vox To Wav Converter
Thanks, Liqdfire,
Actually, I'm a VB programmer using VB.NET... been doing various forms of BASIC for about 25 years.
Thanks for the C++ code, I don't think I'll use it though. Too much learning curve to get going with it.
Sometimes I get C# code and can either read it or convert it, though.

Yeah I am a VB .Net developer as well, I am in the middle writing a complete audio compression / decopression library in VB .Net complete managed code but there is a lot of work to be done on it as of yet. If I get something new on this I will post it for you.
