Bitrate_index
indicates the bitrate (Kbit/sec) depending on the MPEG ID.
Sampling Frequency
indicates the sampling frequency of the encoded audio signal (KHz) depending on the MPEG ID
Padding bit
if this bit equals ’1’, the frame contains an additional slot to adjust the mean bitrate to the sampling fre-
quency, otherwise this bit is set to ’0’.
Private bit
Bit for private use. This bit will not be used in the future by ISO/IEC.
Mode
Indicates the mode according to the following table. The joint stereo mode is intensity_stereo and/or
ms_stereo.
