我有两个相同长度的声音文件,我想按顺序播放。具体来说,我希望第一个文件播放三次,第二个文件播放一次。
我可以通过SfPlayer
和TrigFunc
来实现这一点,但我的印象是每次切换声音时都会从磁盘读取声音文件。有没有办法通过SndTable
,which holds the sounds in RAM?
以下是使用SfPlayer
和TrigFunc
,using this example as inspiration的解决方案。
from pyo import *
s = Server().boot()
DOWNLOADS = 'C:\\Users\\mmoisen\\Downloads\\'
first = DOWNLOADS + 'first.wav'
second = DOWNLOADS + 'second.wav'
sf = SfPlayer(first, speed=100/135.0, loop=True, mul=0.5).out()
count = 0
def foo():
global count
count += 1
print count
if count == 3:
sf.path = second
if count == 4:
sf.path = forst
count = 0
trig = TrigFunc(sf['trig'][0], foo)
s.start()
答案 0 :(得分:0)
要从RAM顺序播放声音文件,我只需要在append
上拨打SndTable
,就像这样:
from pyo import *
s = Server().boot()
DOWNLOADS = 'C:\\Users\\mmoisen\\Downloads\\'
first = DOWNLOADS + 'first.wav'
second = DOWNLOADS + 'second.wav'
# Using an array like this didn't work; it just played the first clip
# t = SndTable([first,first,first,second])
t = SndTable(first)
t.append(first)
t.append(first)
t.append(second)
a = Osc(table=t, freq=t.getRate(), mul=.4).out()
s.start()
使用声音文件列表不起作用;它只是反复播放第一个声音。
