- The Driver Settings Panel is displayed.
- "Audio Buffer Size"
- You can adjust the audio input/output buffer size.
- Decreasing the buffer size will shorten the latency and improve realtime performance, but might make it more likely that you will experience audio clicks and pops, depending on your computer's processing power and the song data load.
Increasing the buffer size will lengthen the latency, but will make audio streaming more stable, and it will be less likely for audio clicks and pops to occur.
- In general, you'll probably want to decrease the buffer size for better realtime performance if you're playing a software synthesizer in real time, or if you're monitoring an audio input that's being passed through your DAW software.
Conversely, you can increase the buffer size to prevent audio clicks and pops if you're recording or playing back song data that contains numerous tracks and presents a heavy processing load.
- By changing the buffer size as appropriate for your situation, you can obtain the right balance between realtime performance and audio streaming stability.
-
- "Recording Margin"
- If the recorded audio data contains sound dropouts or noise even after you've adjusted the audio buffer size in your software and also adjusted the above "Audio Buffer Size," try increasing this "Recording Margin" setting.
* | For some software, it may not be possible to adjust the buffer size. |
-
- "Recording Timing"
- If the timing of the recorded audio data is not correct, adjust this value.
-
- Note)
