# Recording Quality — VoiceNet dimension guide

*Category:* Language & Recording · *code:* `vn_RCQL` · *slot:* 72

This dimension measures the technical fidelity and cleanliness of the recording. Merge the `__high` / `__low` LoRA from `laion/moss-voicenet-dimension-loras` at 25/50/75/100/125%. Costs are shifts vs. the 24-sample neutral baseline.

**TL;DR.** **Recording Quality** controls the technical fidelity and cleanliness of the recording. The **__high** LoRA shifts it +0.14 at 125% (worst cost: burst-blend -0.16); the **__low** LoRA shifts it -0.30 at 125% (worst cost: speech quality -0.31). The **__low** direction is the stronger, more reliable knob here.

## ▲ HIGH — Recording Quality __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.518 | — | — | — | — |
| 25% | 0.622 | +0.10 | -0.04 | +0.03 | +0.11 |
| 50% | 0.634 | +0.12 | -0.06 | -0.06 | +0.12 |
| 75% | 0.638 | +0.12 | -0.06 | -0.07 | +0.10 |
| 100% | 0.648 | +0.13 | -0.08 | -0.20 | +0.13 |
| 125% ★ | 0.654 | +0.14 | -0.11 | -0.16 | +0.15 |

- **EmoNet emotion** — ↑ Emotional Numbness (+0.52), Contemplation (+0.47), Contentment (+0.41); ↓ Fatigue/Exhaustion (-0.57), Impatience and Irritability (-0.56), Longing (-0.48)
- **VoiceNet dimension** — ↑ Teacher/Didactic Style (+0.84), Esthetics (+0.83), Valence (+0.79); ↓ Disfluency (-0.77), Cognitive Load (-0.69), Respiration (-0.58)

Merging **Recording Quality __high** ramps the dimension: at the recommended **125%** dose the measured Recording Quality score moves from a 0.52 baseline to 0.65 (a +0.14 shift). The dose-response is clean and monotonic — each step pushes the dimension further. That reach is a real cost — the biggest hit is to **burst-blend** (-0.16); across the board genuineness -0.11, burst-blend -0.16, speech quality +0.15. Emotionally it reads as Emotional Numbness (r 0.52), Contemplation (0.47) and Contentment (0.41), and it moves away from Fatigue/Exhaustion, Impatience and Irritability and Longing. On other voice dimensions it co-moves most with Teacher/Didactic Style (0.84), Esthetics (0.83) and Valence (0.79), while pulling down Disfluency, Cognitive Load and Respiration. Practical call: merge __high at **100–125%**; expect Emotional Numbness and Teacher/Didactic Style to rise and burst-blend to fall. If you don’t want Emotional Numbness bleeding in, offset it with a prompt cue toward Fatigue/Exhaustion to keep the recording quality shift without the side-effect.

## ▼ LOW — Recording Quality __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.518 | — | — | — | — |
| 25% | 0.452 | -0.07 | +0.01 | -0.05 | -0.07 |
| 50% | 0.345 | -0.17 | +0.06 | +0.01 | -0.17 |
| 75% | 0.433 | -0.08 | +0.02 | -0.14 | -0.04 |
| 100% | 0.271 | -0.25 | +0.04 | -0.15 | -0.26 |
| 125% ★ | 0.216 | -0.30 | +0.04 | -0.22 | -0.31 |

- **EmoNet emotion** — ↑ Contemplation (+0.80), Interest (+0.77), Affection (+0.73); ↓ Fatigue/Exhaustion (-0.71), Pain (-0.57), Distress (-0.46)
- **VoiceNet dimension** — ↑ Esthetics (+0.94), Smoothness (+0.90), Warmth (+0.90); ↓ Disfluency (-0.78), Playful Style (-0.76), Genuineness (-0.57)

Merging **Recording Quality __low** suppresses the dimension: at the recommended **125%** dose the measured Recording Quality score moves from a 0.52 baseline to 0.22 (a -0.30 shift). The dose-response is clean and monotonic — each step pushes the dimension further. That reach is a steep cost — the biggest hit is to **speech quality** (-0.31); across the board genuineness +0.04, burst-blend -0.22, speech quality -0.31. Emotionally it reads as Contemplation (r 0.80), Interest (0.77) and Affection (0.73), and it moves away from Fatigue/Exhaustion, Pain and Distress. On other voice dimensions it co-moves most with Esthetics (0.94), Smoothness (0.90) and Warmth (0.90), while pulling down Disfluency, Playful Style and Genuineness. Practical call: merge __low at **100–125%**; expect Contemplation and Esthetics to rise and speech quality to fall. If you don’t want Contemplation bleeding in, offset it with a prompt cue toward Fatigue/Exhaustion to keep the recording quality shift without the side-effect.
