The Playback buffer length setting is found in File > Settings under the Advanced tab and controls the amount of audio data that PlayIt Live buffers before playing it back through your audio devices.

How it affects performance:

Increasing the playback buffer length decreases the chance of audio breaking up or dropping out on slower computers, but it also increases the latency (delay) when processing audio. This creates a trade-off between audio stability and responsiveness.

When to adjust this setting:

• Increase buffer length if you experience audio dropouts, glitches, or break-ups during playback, especially on older or slower computers
• Decrease buffer length if you need lower latency for live broadcasting situations where timing is critical, such as when using microphones or external mixing equipment

Important considerations:

A restart of PlayIt Live is required to apply any changes to the playback buffer length setting. The default setting works well for most users, so only adjust this if you're experiencing specific audio performance issues.
