What is playback?

What Does playback Mean

The notion of playback has its origin in the English language. Also referred to as play back , it refers to the reproduction , within the framework of a concert or show , of music that was previously recorded .

An artist who does playback, therefore, moves his lips as if he were singing , when in reality what the public hears is a recording . Similarly, musicians can pretend to play their instruments live while a recorded sound is played.
Playback, in short, is a simulation . It is a common resource in television programs, where a concert is usually staged with the presence of soloists or musical bands who "act" their role.

For playback to be successful, it is imperative that there is precise timing between actions and recording. Whoever sings must move their lips simultaneously with what is expressed in what is recorded, and the musicians must be attentive to their own participation.
Playback is often a hoax . There are those who pay a ticket to listen to their favorite artists live but end up attending a playback session because the protagonist has problems with his voice , does not know the songs or another cause.
On television, playback by singers and marching bands can be forgiven at times; for example, if the stage characteristics you give them do not meet your acoustic requirements to produce good sound . In fact, many times television producers "force" their guests to use recordings because they do not give them the possibility to organize themselves before the presentations.
We must not forget that interpreting a song live with electronic instruments and amplification requires several hours of previous work by different professionals, to fine-tune the volume levels of the microphones and headphones, tune the instruments, place them on stage and do at least one trial. If there is not enough budget for all this, or if the artists are not given enough time to prepare, then playback is preferable to a low quality show.
Beyond music , playback resources are frequent in the field of cinema . It is common for dialogue to be re-recorded in post - production and added via lip sync. Animated films and dubbing work also make use of such techniques. In these cases, however, we do not usually talk about playback.

With regard to the songs and other musical pieces that appear in the films, it is also very common for them to be recorded in the studio, edited and only later filmed the scenes in which the characters interpret them, even if the actors do nothing other than playback over your recordings. In this case there is also another possibility: that the musicians are not the actors, with which the need for playback is even greater.
In a movie , lip syncing to a music scene is not considered a hoax or negative practice; on the contrary, since filming sessions are often exhausting and multiple takes of each part are usually taken, it would be abusive to require actors to perform their parts every time a scene is filmed. This does not mean that some directors may opt for this requirement: in the film Les Misérables , based on the eponymous book by Victor Hugo, the actors were forced to actually sing during filming, regardless of the conditions they had to undergo (such as be with half your body submerged in the water).
