Marf Audio Analysis : Where can I find data for SpeakerIdent app?

Question

I am using SpeakerIdentApp of marf for audio analysis . I wanted to explore it with more data other than provided by speakerIdentApp . I tried with some of the wave files at : http://www.wavsource.com/ but those files are not supported by marf .

nullwave is not 16 bit file

Then a tried SOX to covert the files into 16-bit .But the files are MP3 encoded and it doesn't support mp3 encode wav file .

So my Problen is to find data which is supported by marf 16-bit wave files .

Answer 1

Marf Only Support

bit Rate = 16-bit 
sampling rate = 8000Hz

One may find training sample from Marf Site With SpeakerIdentApp .Samples

But the problem is that the samples are not good with real world entities .

So One may Download any Wav files . Then the person has to convert that file to wav 16-bit 8000HZ

may use to convert ->  Ubuntu : Sound Converter
