# Room tone under a generated voice

Edit / Sound / Voice. Checked 2026-11-13.

A generated line stops sounding generated between the words.

- Use when: Text-to-speech voice-overs.
- Phrase: lay recorded room tone under every generated line, roll off the highs above 7 kHz, add light compression and a short room reverb

## Watch out

- Measured on 28 Oct 2026: a generated line drops to digital zero between words, -240 dBFS in the quietest 50 milliseconds; a recorded line never does. With a stand-in room tone the quietest moment rose to -67.7 dBFS. (measured; Director Chair field notes on motion graphics)
- The recipe is one studio's. Whether the result sounds natural is judged by ear, not by the meter. (practitioner; Director Chair notes on Video from code at Anfloy (Dima Bilous))

Give me a sound brief: what to record or pick, where it sits on the timeline, the levels, and what to check before export, for a short video about [your product], for [your audience]. The technique is room tone under a generated voice: a generated line stops sounding generated between the words. How it works: lay recorded room tone under every generated line, roll off the highs above 7 kHz, add light compression and a short room reverb. It is right for: text-to-speech voice-overs. Measured on 28 Oct 2026: a generated line drops to digital zero between words, -240 dBFS in the quietest 50 milliseconds; a recorded line never does. The recipe is one studio's. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing.
