<chan> indicates the channel for multi-channel sequences (f<number> - number of the front channel, b<number>- number of the back channel, s<number> - number of the side channel, l<number> - number of the LSF channel).
<coder> indicates the coder used to encode the content (ce – CELP, sa – Structured Audio, pcm – PCM)
<coreSetup> refers to a certain audio coder setup. It is most likely a number, but might also contain characters.
<delay> refers to the decoder delay, it can become "ld" (low delay) or "nd" (normal delay).
<epConfig> can be 0, 1, 2 or 3, depending on epConfig (defined in AudioSpecificConfig).
<epSetup> is required if (epConfig==2 || epConfig==3). It refers to a certain error protection setup.
<fs> sampling frequency (08, 11, 12, 16, 22, 24, 32, 44, 48, 64, 88 or 96).
_level<lvl> refers to the level with regard to DRC.
_cut<fac>_boost<fac> referes to the cut and boost factors with regard to DRC.
_lay<highestLay> is required for any scalable configuration. It marks the highest layer of the scalable configuration used for decoding (starting with 0 for the core layer).
_p<pitchfac> is a number refering to the decoder configuration with regard to the pitch factor.
_ref<decCfg> is a number refering to the decoder configuration with regard to delay mode, speed and pitch change.
_s<speedfac> is a number refering to the decoder configuration with regard to the speed factor.
