在开始学习基于音频R包和其他包的时候我遇到了2个问题:
- 声音很难听，听不懂
- my console is filled with messages
一开始我得到这些消息:
ALSA lib pcm_dsnoop.c:641:(snd_pcm_dsnoop_open) unable to open slave
ALSA lib pcm_dmix.c:1089:(snd_pcm_dmix_open) unable to open slave

ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
经过一些猜测尝试和谷歌搜索错误，我设法删除了其中的大部分，我现在只得到那些(编辑，我仍然得到第一个消息，他们只是变得很少:/):
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred
错误行数是随机的有时没有错误有时一堆。
我用简单的play(sin(1:10000/20))代码和Rmusic包来使用音频包:play_music(c("B5","A5","G5","F#5","E5","D5","C#5","B4"),c(1,1,1,1,1,1,1,1))
两者都犯了相同的错误
我在kubuntu 20.04最新的R-base安装3.6.3
> audio.drivers()
name description current
1 portaudio PortAudio driver TRUE
Portaudio19-dev在开始测试前安装
我的"银屏"也有类似的问题。文本到语音的python框架:
ALSA lib pcm.c:8545:(snd_pcm_recover) underrun occurred silero
我通过安装"软件"应用程序"中建议的编解码器来修复它。
插件→编解码器→GStreamer多媒体编解码器安装
我安装了所有建议的编解码器，并重新启动。对我来说，错误已经消失了。GL !
我在pygame.mixer中遇到了这个问题(而且声音很恶心)。
我在患有als的饮食习惯上运行它。
pygame.mixer.pre_init(frequency=48000, buffer=2048)
self._mixer=pygame.mixer.init()
我以频率调用pre_init()增加了缓冲区的大小.
现在声音好多了，没有漏音了
