2.2.2 Profile Quality Settings
Each of the low-sample-rate profile groups has eleven quality profiles, numbered from
00 to 10. The high-sample-rate profile groups have six quality profiles from 00 to 05.
This chapter presents the five profile groups and gives estimates of typical bitrates that
can be obtained with the profile.
In general, quality setting 05 is designed to be a typical value that gives good quality
for the application. Qualities 00 and 01 are for emergency use only when there just
isn’t storage space for better quality settings. High qualities, starting from 07 or 08,
are intended for transparent sound quality, the intent being that compression cannot be
heard anymore even under stringent circumstances.
The “Voice” Profiles
The “Voice” profiles are intended for speech applications.
These profiles support Vox and Pause.

The “Wideband Voice” Profiles
“Wideband Voice” is intended to be used when high speech quality is required.
These profiles support Vox and Pause.

The “Wideband Stereo Voice” Profiles
“Wideband Stereo Voice” is intended to be used when high speech quality with direc-
tional information is required.
These profiles don’t support Vox and Pause.
