Lip-synching, as the name suggests, is when the singer doesn't really sing his voice when he performs, but through pre-recorded audio. This phenomenon is not uncommon in various ** programs and concerts, but it is often difficult for the audience to perceive. So, how do you determine if a song is falsetto?
First of all, we can judge from the pitch and rhythm of the song. Real singers are very accurate in pitch and rhythm when singing, while lip-syncers may have pitch deviations or unstable rhythms. This is because when a lip-synchro sings, they are actually mimicking pre-recorded audio, rather than actually singing.
Secondly, we can judge from the singer's mouth shape and breathing movements. When a real singer sings, the mouth shape and breathing movements are closely related to the rhythm and melody of the song, while the lip sync and breathing movements may not match the rhythm of the song.
Again, we can judge from the sound of the scene. When a real singer sings live, the sound effect tends to change due to the influence of the live environment, while the lip singer can ensure the consistency of the sound effect with pre-recorded audio.
In the end, we can judge from the singer's reaction. When a real singer sings, he or she reacts accordingly to the emotion of the song and his or her own feelings, while a lip singer may appear more aloof and not really emotionally engaged.
In general, determining whether a song is lip-syncing requires a combination of factors, including pitch, rhythm, mouth shape, breathing movements, live sound effects, and the singer's reaction. Although this requires a certain amount of expertise and experience, if we look closely, we will be able to find the flaws.
