    I have 10 GB worth of voice MP3 files (at 128 Kb/s). I want to compress them to fit into an 8GB MP3 player I have. I'm not too concerned about quality because voice doesn't matter as much. How can I compress these MP3 files down? What's the minimum bit rate to hear the human voice comfortably?

    Thanks. Baedaebok

    Great question. The lower the bit rate the lower highest pitch can be. The high end of a human voice is 2 kHz. 16 CBR will capture that faithfully for sure maybe even 8 might do. I use 16.

    I suggest downloading the trial version of dbPowerAmp. Load all the codes you think you will ever need. The app will not work after the 30 days but the utilities that are called from file Explorer do not expire. I would also rip any of your CDs in this period. I think it has the best ripper on the market. It is the smartest, fastest and easiest to use for sure. The utilities are more handy and work faster as well. You highlight the files you want to convert and right click.

    I suggest using LAME that will goes down to 8 CBR, it does 16 CBR.

    Mez...thanks man for your guidance to use a low bitrate like 32. I downloaded a dozen MP3 compressors. An article in online PC World mentioned "Blaze Media Pro". I ended up using this because I could open Folders to compress all the files within (and retain the same folder structure in the output) while most other programs would only open individual files to compress. Since I needed to compress 312 MP3 voice files, Blaze Media Pro was the only program where I could open folders to compress without clicking each file to compress.

    Cheers. BDB

    Audacity can do the same job. Will import all your 300 audio files, and compress/convert to whatever format you need. And is free(not to forget awesome!).

    I probably average over 100 albums a week. I would have to be very simple indeed not to know if you can do an album at a time. Infact you can do a hundred albums in a hundred folders in a batch if you like.
