OBS Studio + voice changer: the complete stack for streaming, recording and content production

OBS Studio is where audio actually gets mixed for any serious streamer. Twitch, YouTube, Kick, local recording for TikTok/Reels — it all flows through OBS in a pro workflow. Adding a voice changer to the pipeline transforms what reaches your audience, but it pays to understand where VoxBooster slots into the processing chain.

The basic pipeline

Without voice changer:

Physical mic → Windows driver → OBS (filters: noise gate, compressor, EQ) → Encoder → Stream

With voice changer:

Physical mic → Windows driver (VoxBooster intercepts) → OBS (receives transformed voice) → Encoder → Stream

Interception happens before OBS receives the signal. You don’t need to configure anything special in OBS — it keeps using your real mic as input device, and automatically receives the already-modified voice.

Straight setup

1. Install VoxBooster, log in, enable Real-time on the desired voice.
2. Open OBS.
3. Settings → Audio → Mic/Auxiliary Audio Device.
4. Pick your real mic (not a virtual device).
5. Confirm levels show up on OBS meters when you talk.
6. Start stream/recording.

VoxBooster always running in parallel. OBS captures audio that already came out transformed.

OBS filters after the voice changer

OBS supports a chain of filters applied to the mic. Recommended order after the voice changer:

1. Noise Suppression: leave it off. RNNoise (default filter) can mistake transformed voice for noise and cut chunks of it. VoxBooster has its own suppression that runs before the transformation.

2. Noise Gate: light usage is fine. Threshold at -45dB, attack 5ms, release 100ms. Cuts dead silence without touching the voice.

3. Compressor: apply lightly. Ratio 3:1, threshold -18dB, attack 6ms, release 60ms. Smooths peaks without sounding squashed.

4. Equalizer: optional, to tweak the timbre of the transformed voice if the clone sounds too dark/bright. Careful — neural voice already ships pre-balanced.

5. Limiter: apply at the end. Threshold -1dB. Prevents hard clipping if you scream.

Desktop audio capture

To capture audio coming out of the PC (music, game, notifications), use Desktop Audio in OBS. That’s separate from the voice changer — VoxBooster only modifies mic input, not speaker output.

Recommended streaming setup:

• Mic/Auxiliary: your real mic (with VoxBooster transforming)
• Desktop Audio: capture from the default output device

Audience hears your transformed voice + game audio, all mixed.

Local recording for YouTube

Same setup. OBS records to a local file (.mkv or .mp4) with the transformed voice already baked in. Edit in DaVinci Resolve / Premiere afterwards as usual — recorded audio is the transformed voice, not your natural one.

Offline mode for production polish

For content where you want maximum quality (short film, dubbed animation, audiobook), use VoxBooster’s Offline mode:

1. Record your raw voice in OBS (voice changer off).
2. Export the audio from the MKV/MP4.
3. Open VoxBooster → Process File.
4. Pick the desired voice and drag the audio file in.
5. Get the transformed audio at peak neural quality.
6. Re-import into the video editor.

Offline mode uses a beefier neural model (no latency constraint), producing more polished voice than real-time. For evergreen content, it’s worth it.

Multi-track audio

OBS supports multi-track recording. Advanced setup:

• Track 1: transformed voice (goes to stream and recording)
• Track 2: raw voice (separate recording to edit later if needed)
• Track 3: desktop / game audio
• Track 4: separate soundboard audio

To run raw voice in parallel with transformed voice you need a dual input. VoxBooster has a “Dual Output” option that creates a second virtual device with raw voice, while the main device serves transformed voice. In OBS, you add both as separate inputs.

Streaming to Twitch + YouTube simultaneously

OBS with the Multi-RTMP plugin (or recent native OBS Studio versions) lets you stream to two endpoints. Voice changer applies to both automatically — because the transformation happens before the encoder.

Stream latency

OBS adds ~50-200ms of encoder buffer. Voice changer adds:

• Effect: 5ms
• Default neural clone: 480ms
• Low-latency clone: 250ms

Stream total: 50-680ms (max). Twitch low-latency mode runs ~3 seconds total delay for the viewer. The voice changer fits inside that delay with zero perception by the audience.

For chat interaction (answering a question), you’re using Twitch’s standard 5s delay. No noticeable extra latency from the voice changer.

NDI conferencing

Pro setups use NDI to push feeds between machines. Voice changer on source PC → OBS on destination PC via NDI → stream. Works transparently — NDI carries already-transformed audio.

For streaming via Discord screen share

Common case: streamer screen-shares in Discord with friends while also streaming to Twitch. Voice changer transforms voice on both channels simultaneously. No extra config needed — both pull from the same intercepted Windows mic.

Compatibility

OBS Studio (Windows): voice changer runs perfectly.

OBS Studio (Mac/Linux): VoxBooster is Windows-only in 2026, so it doesn’t run on other OSes.

Streamlabs Desktop: works identically (it’s an OBS fork).

Twitch Studio: works, but you get less filter control.

Lightstream / cloud streaming: depends. If audio capture is local on your PC and sent to the cloud encoder, it works. If capture happens directly on the cloud (e.g., stream bot), the voice changer has nowhere to run.
