-filter_complex
enables the complex filtering to manage splitting the input to two audio streams
[0:a:0]asplit=2[a][b];
asplit allows audio streams to be split up for seperate manipulation. This command splits the audio from the first input (the master file) into two streams "a" and "b"
[b]afifo[bb];
this buffers the stream "b" to help prevent dropped samples and renames stream to "bb"

[1:a:0][bb]concat=n=2:v=0:a=1[concatout]
concat is used to join files. n=2 tells the filter there are two inputs. v=0:a=1 Tells the filter there are 0 video inputs and 2 audio inputs. This command appends the audio from the second input to the beginning of stream "bb" and names the output "concatout"

-map "[a]"
this maps the unmodified audio stream to the first output
-codec:a libmp3lame -dither_method modified_e_weighted -qscale:a 2
sets up mp3 options (using constant quality)
output_file
path, name and extension of the output file (unmodified)
