Ogg Vorbis Export Setup
- Quality: Choose a quality setting from 0 (lowest) to 10 (best). The current quality setting is displayed in the center of the slider. The default level of 5 typically produces a file of about the same size as Audacity's default 128 kbps MP3 encoding, but of higher quality. Higher OGG quality settings mean a larger file size, because a higher overall bit rate will be used.
This means that in order to maintain consistent quality throughout a track, a higher bit rate will be used when encoding a complex piece of audio (such as a full orchestral passage) than when encoding a solo voice or instrument. A recording which has more complex audio will produce a larger file. Increasing the sample rate in Selection Toolbar will increase the bit rate and so the file size (and vice versa).
