提供了PortAudio运行库,可以做到低延迟声音输出。可说是很大的进步。在win7和以后的操作系统中都可以使用此运行库
mame 0.182 whatsnew.txt中的描述:
-Updated PortAudio library and added audio output module. [inte alls]
* Provides low-latency audio output on Windows 7 or later and Linux.
mamedev.org站点上,0.182 news中的描述:
We’ve received a contributed PortAudio output module and integrated it in this release. This provides a cross-platform low latency audio output solution. Performance should be similar to Steinberg ASIO on Windows 7 or later without the licensing issues, and better than SDL audio on Linux. It can be enabled by setting the sound parameter to portaudio on the command line or in an ini file. Of course, all the other audio output modules are still supported, so if you're happy with your current setup you don’t have to change anything.
使用PortAudio运行库输出声音的方法:
1、把mame 0.182 64位版解压到一个干净的目录中,使用mame64 -cc这个命令行语句建立mame.ini
2、用文本编辑软件打开mame.ini,修改如下项目,改成以下数值
#
# OSD SOUND OPTIONS
#
sound portaudio
pa_api "Windows WASAPI"
pa_device none
pa_latency 0.003334
audio_latency 1.0
或
#
# OSD SOUND OPTIONS
#
sound portaudio
pa_api "Windows WDM-KS"
pa_device none
pa_latency 0.001
audio_latency 1.0
两个设置方法都可以使用PortAudio运行库
然后即可享受低延迟声音输出
