# Sound

The **Sound** tab configures audio output. Use **Save** for your global defaults
or **Save for ROM only [*]** to apply settings to the
[selected ROM](index.md#global-vs-per-rom-settings).

| Setting | Description |
|---------|-------------|
| **Enable Sound** | Master switch for all audio. |
| **Frequency** | Output sampling frequency. Set this as high as your system allows without affecting performance; the default works on most systems. |
| **Samples** | Audio buffer size, in samples. Smaller buffers reduce latency; larger buffers are more tolerant of system load. Tweak only if you hear stutter or crackle. |
| **Auto Buffer Size** | Let kat5200 choose the host audio buffer size automatically. This is the recommended starting point. |
| **Buffer Size** | Manual host audio buffer size. Appears only when **Auto Buffer Size** is off; raise it if audio stutters, lower it if latency matters more. |
| **Volume** | Output volume level. |
