I would like to convert a sound file (from a digital voice recorder) with the extension .voc to an .mp3 file or some other common sound files. I am on Windows 7 64 bit.

I have tried the program voc2wav but it gives me an error message saying that the program isn't 64 bit.

I need a solution that does not require installing software. (The voice recorder did come with a program that I could install, but I would like to avoid that).

  • What is wrong with installing a program? – Moab May 15 '12 at 0:37
  • @Moab There is nothing wrong with installing a program... I would like something that I could run of a USB drive. But if I don't find a standalone program, I will just have to install the software. – Thomas May 15 '12 at 0:39

    I bet the portable version of VLC can convert it...videolan.org/vlc/download-windows.html – Moab May 15 '12 at 0:40
  • @Moab Ok, I will try that. I see that it is quite a huge program though. – Thomas May 15 '12 at 0:43

VLC Player should be able to read .voc files. You can use its built-in conversion feature (go to Media -> "Convert / Save..." or hit Ctrl+R) to convert them to MP3s.

VLC Player is free and is available as a portable version that doesn't require installation, so seems to meet all your requirements.

Edit: in case your .voc files are in the RCA-VOC proprietary format, rather than the more common Creative Voice format, try this online converter. Or if you want to be able to do it offline, get devoc (that the online converter is based on) to convert your .voc files to .wav, then use LAME to convert them to MP3s. Note, however, that devoc is 16-bit and thus won't run on 64-bit Windows.

Edit2: I compiled devoc to a 32-bit executable that runs on both 32-bit and 64-bit Windows. You can download it here. I tested it with the sample .voc files posted on the devoc homepage and it converts them to .wav just fine.

  • This is what I was looking for. However, it doesn't seem to work. On videolan.org/vlc/features.html it looks like VLC doesn't support the .voc format... ? – Thomas May 15 '12 at 1:19
  • @Thomas VLC does support .voc, it's listed as Creative Voice. However, your files seem to be in another, proprietary format that just happens to use the same file extension. See the edits in my answer for a possible solution. – Indrek May 15 '12 at 12:56
  • That was exactly what I needed. Thanks a bunch for compiling the program! It works perfectly! – Thomas May 15 '12 at 18:27

Never used this but looks promising

Audio/Video to EXE Converter is a Portable Software that allows you to convert Audio and Video files from one format to another. The utility can be used as either a converter or player. In addition, you can create self playing executable files from your audio or video files. Audio to EXE, Video to EXE etc. You can play the resulting exe without a dedicated player and accompanying codec. It works standalone.

Audio Video to EXE

Supported conversion formats: 3gp, aac, ac3, aiff, asf, avi, exe, flac, flv, gif, m1v, m2v, m4v, mka, mkv, mov, mp2, mp3, mp4, mpc, mpg, nut, ogg, ra, rm, swf, vob, voc, wav, wma, wmv, wv, yuv

  • I just tried this on my files and it claims that it is an unknown format.... ? – Thomas May 15 '12 at 1:19
  • It mat be a proprietary format of voc, you may have to use the software that came with the VR, or try VLC. – Moab May 15 '12 at 1:22
  • Thanks for the effort though. I did try the VLC and that also doesn't work. I am wondering if the format is really voc... – Thomas May 15 '12 at 1:24
  • They can use any file extension they want, more than likely it is a proprietary file format that uses the voc file extension. See if mediainfo can tell what it is...sourceforge.net/projects/mediainfo – Moab May 15 '12 at 1:42

For converting offline you could also try to use Audacity, As far as I know you can install additional codecs if you need to, I'm not sure if they support VOC out of the box, but they support pretty much anything.
