change the Audio rendering settings (not APU or emulation). My Nes uses Direct
Sound as audio renderer. Playback and Record settings is fixed to 44100 Hz
- 16 Bit PCM - Mono. The Band-Limited Sound Buffer "Blip_Buffer"
> is applied to Nes emulation sound output and thus it applied in
playback and record as well.
- To open the
audio settings window, go to Settings>Audio or press CTRL+SHIFT+A.
In the audio
playback: indicates if the sound
playback is enabled or not.
size: allows to set sound playback
and "Blip_Buffer" buffer sizes. 8KB is good for
performance and quality, 16KB produce more quality sound but may reduce
- Volume: allows to adjust the volume level
the difference between generated sound and playback buffer pointers during
game play, measured by BufferSize Percentage. Bigger latency values is
better but not likable since it changes the playing experience.
- Use Save button to save and
apply. Use Cancel button
to discard changes. Use the Defaults
button to restore default settings.
- Changing Buffer size and Latency values may
improve sound quality and performance.
- When the
sound get ugly (losing synchronization), pause the emulation (Press
F2) for 2 seconds or more then resume the emulation (Press F2 again). This
should reset pointers and then fix the sync problem.
