radicem Posted December 14, 2006 Share Posted December 14, 2006 I'm doing lots of interviews for my PhD research, using a digital recorder. My sound files are all one-to-one interviews lasting from 20 mins to about 3hrs (usually broken up into smaller files because of interruptions, but could be merged into long files). What sound file format and medium would anyone recommend for long-term storage and backups? e.g. mp3 / wav / ogg on CDs / USB stick / back-up portable hard drive (or all three!) I'm currently working mainly with the proprietary format of my digital recorder, but since that's a borrowed item, it's not a long-term storage option! Many thanks in advance for your replies.

nchtj Posted January 2, 2007 Share Posted January 2, 2007 save to .wav using the GSM codec save to either USB drive or external drive, a CD is no good for lots of data since its size to data-capacity ratio is no good. Link to comment Share on other sites More sharing options...

Thank you very much for the advice. Presumably you recommend that format and codec because it is the best quality? Link to comment Share on other sites More sharing options...
nchtj Posted January 16, 2007 Share Posted January 16, 2007 gsm .wav is optimized for voice in terms of quality vs. filesize Link to comment Share on other sites More sharing options...
