# Audio setup

Audio setup is the only technical hurdle you should solve before making your first beat.

## Output device

Start with the system default output device unless you already know you need something else.

In Settings, Meiji Sampler exposes:

* audio host
* output device
* Stereo Channels
* buffer size
* sample rate
* input device
* input channel

## Buffer size

Meiji Sampler supports these buffer sizes:

* `64`
* `128`
* `256`
* `512`
* `1024`

Recommended starting point:

* `64` if you want the lowest possible latency and your machine can handle it
* `256` if your machine is reasonably fast and you want tighter response
* `512` if you want a safer default

If you hear crackles, underruns, or glitching, move up to `512` or `1024`.

## Sample rate

Available sample rates:

* `44100 Hz`
* `48000 Hz`
* `88200 Hz`
* `96000 Hz`

Recommended starting point:

* `44100 Hz` for most users
* `48000 Hz` if it matches the rest of your setup

Higher rates use more CPU. If playback is unstable, increase your buffer size before reaching for a lower sample rate.

When you change the audio host, output device, buffer size, or sample rate, Meiji Sampler saves the preference and asks whether to restart the audio engine when you exit Settings. Choose **\[Apply Now]** to use the new settings immediately, or **\[Next Launch]** to keep the current engine running until you reopen the app.

## Linux audio hosts

On Linux, the audio host can be:

* `Auto`
* `ALSA`
* `JACK`

If `Auto` is unstable, try `ALSA`. If you already run a JACK setup, use `JACK`.

## Input setup

If you want to sample external audio or use the recording feature:

1. choose the correct input device in Settings
2. select the input channel or stereo pair you want to record
3. test monitoring before starting a real take
