music ducking
Takes a voice recording and a music track and returns one mix in which the music is lowered by sidechain compression whenever the voice is present and returns in pauses — the standard podcast and voice-over sound. The music is looped or trimmed to the voice length, starts at the chosen bed level and fades out at the end; the voice is levelled first. Depth of ducking and music level are selectable, and the mix is brought to the target loudness, measured afterwards. Billing per started minute.
