Sound design: editing vocals

I transplanted a vocal performance from one song to a different one by manipulating pitch, formants and tempo. Plus, cleaning up historical speeches.

Vocal transformation

After the demo stage of my album After 1989, I scrapped a song called Niemandsland, featuring a marvellous vocal performance by Rachel Goodman. Since the lyrics were critical for the concept, I repurposed them for the new lead single Skinny Kid. Despite the two songs having different tonality and tempo, I decided to salvage Rachel’s parts as backing vocals and counterpoint to Dan Ecclestone’s lead.

Before & after

Rachel Goodman’s performance in Niemandsland (an unpublished demo scrapped in 2017) and the same chorus section edited and adapted for Skinny Kid. The tempo jumped from 78 to 105.

The painstaking process of transforming a vocal performance from one song to another was done using Logic Pro and Soundtoys. Working on both the pitch and the formant, I strived to obtain a new track that sounded coherent with the new lead single without showing notable artifacts.

Robert F. Kennedy eulogy clean-up

I love restoring audio for historical speeches. A famous eulogy given by Robert Francis Kennedy in 1968 after Martin Luther King’s assassination was used in this song. iZotope RX was the only tool I used.
