Creative MuVo V100 with Linux

I am currently testing a Creative MuVo 100 under Linux. I am planning to use this to record some sound snipplets or interviews. Main reason for this blog entry is to say: yes it works! If you are interested in buying such a device. the sound quality is not really good – and recording works a little difficult at first. first you best erase the existing intro file on this device. Then
you needto press the scroll wheel to get into the upper menu. What the manual doesnt tell you is how to record:

  • Go to the microphone men entry and select it with pressing the wheel.
  • You now get a display of how much time is left to record.
  • You start recording by pressing the play/pause button once.
  • I had trouble recognizing that it is recording. But it did it.

My version has 2 GB of memory and it shows me I have recording time of about 138 minutes. Thats more than 2 hours. Mplayer can play it and it shows this on Foresight Linux 2 Alpha 3:


$ mplayer voc002.wav
MPlayer dev-SVN-rUNKNOWN-4.1.1 (C) 2000-2007 MPlayer Team

I am not an audio expert, but what i did find out is that this is not a normal WAV but seems to be called ADPCM, which is a speech codec thats “quantizes the difference between the speech signal and a prediction that has been made of the speech signal”. Uhm, ok 😉 if that works… A file that is about a bit more than 36 minutes long has the size of: 8,3M of ADPCM or 33MB WAV -a dn recoded to OGG 6 MB, although recoding should rather not be considered because I highly suggest that switching compression algorithms is very costly? Again I am not an audio expert.

So with MPlayer you can read that format. As far as i understood This: (ratio: 4031->16000) means that this generates a 16 kbit audio from a 4031 compressed file? See also G.726. What is interesting is that it seems in U.S. there is no 2GB version of this device. Strangely though the german page tells me I can record 4 minutes only while the american page of Creative says 125 hours! same device – I think both is false. even the 512 MB version should be able to record more than 4 minutes. And OTOH 125 hours that would be five days! LOL, Creative seems to be creative when it comes to numbers. my estimate is that 2.3 hours is right for 2 GB version and maybe 1 hour for the 1 GB version.

Thre recordings you make are put in a folder “Recorded Tracks”. The first one is named “voc001.wav.” and the next are the same. Unfortunately WordPress forbis to upload WAV files (no matter what size). So I decided to rename it to voc001.ppt. So to check it out you should rename it back to voc001.wav.
