		Additionally some resampling can be applied by using the key `fs` followed by the desired sampling rate.
		The general bitstream processing configuration can be locally overwritten for each EVS and IVAS condition with the key `tx`.
		The additional key `evs_lfe_9k6bps_nb` is only available for EVS conditions and ensures a bitrate of 9.6kbps and narrow band processing of the LFE channel(s).
		Also only available for EVS conditions is the `sba_format` key where a SBA format of lower order than the input can be specified for SBA input formats.
		Also only available for EVS conditions is the `sba_fmt` key where a SBA format of lower order than the input can be specified for SBA input formats.
		#### IVAS
		The configuration of the IVAS condition is similar to the EVS condition. However, only one bitrate for all channels (and metadata) can be specified.
		In addition to that, the encoder and decoder take some additional arguments defined by the key `opts`.
