Custom Configuration: Audio

What to change for Rock Band 3 under the Audio tab in RPCS3's Custom Configuration.

A screenshot of Rock Band 3's Audio custom settings, highlighting "Audio Buffer Duration" and "Audio Out" highlighted in blue with a dotted outline, and "Microphone Settings", "Microphone Type" ("Standard"), "Mic1", "Mic2", "Mic3", and "Mic4" in tan with a solid outline.

Tweak depending on audio hardware and CPU:
- Adjust “Audio Buffer Duration“ depending on system.
  - Set this as low as you can before you hear crackling. 32 ms is a decent starting point.
  - Lower values give you less audio latency but use more CPU.
  - Higher values give you more audio latency but use less CPU.
  - Vocalists are affected the most by this, as a higher latency creates a distracting echo. Instrument players can use calibration to compensate regardless of audio buffer setting.
  - You can change this while the game is running, but it will require re-calibrating in Rock Band 3’s system settings.
- Change “Audio Out” to “XAudio2“ - While most users should stay on “Cubeb“, a couple of people have experienced better performance with XAudio2. Your milage may vary.
For Vocalists:
- Set “Microphone Type” to “Standard” or “Rocksmith“.
- Select an input device in “Mic1”, “Mic2”, and “Mic3“ for vocals. If not playing vocals, “Mic1” will be used for voice chat.
