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.
