- Example 1:Overdubbing of a few voices into a larger choral sound.
- Example 2:
Sometimes with a project, especially a new one, one does not have access to the ideal number of performers, both singers and/or musicians. This is where “Over-dubbing” can help.
In this example only 10 people were available, (all singers and including the four soloists) to record a work designed for a choir of 40, plus soloists and a full orchestra.
The solution adopted was to have the singers of each SATB part perform four times, each time positioned slightly differently in relation to the microphone positions. When the four takes for each part were mixed together, it resulted in an accurate representation of four times as many singers of each part in a main choir. The soloists were then recorded individually in a single take each.
As no orchestra was available, the orchestral backing was produced from the full score, using separate tracks for each set of instruments, by using “Sibelius” software and “EastWest” orchestral samples. This had the added advantage, when uses as a simple backing track, played to the singers through monitor loudspeakers, of enabling the singers to remain in pitch, and in time, for the whole piece, without the need for headphones, which many choral singers find unnatural and off-putting.
The unwanted “leaking” of the orchestral backing onto the voice tracks was reduced by having the loudspeakers behind the directional microphones, and further reduced by using speciality phase inversion techniques.
The resultant audio, placed onto a DVD with illustrative photographs as a slide show.
