What do sound engineers do?
They look after all the studio equipment, setting it up at the start of the recording session and dismantling and checking it all again afterwards. They set up sound levels and dynamics (the loudness and softness of instruments) and acoustics within the live room. They then operate the mixing desk and/or recording software and any digital recording equipment during recording, and mix the different recorded tracks together onto the master tape. They then check the tapes, label them, assemble all the information on the recording needed by the record company and do anything else the producer needs them to do with regard to the recording.
