Audacity and File Formats

The table below can help you estimate the kind of mp3 quality/compression and bit rates to use for your own applications. We also give you approximate file sizes to help you compare. For most in-class audio lectures 32 kbps will work. For supplemental recordings that are shorter in length, 64kbps-96kbps will offer better audio quality.
