I've read in a wav file using 'tuneR':
silence<-readWave("silence0.5sec.wav")
I run summary(silence):
Wave Object
Number of Samples: 22051
Duration (seconds): 0.5
Samplingrate (Hertz): 44100
Channels (Mono/Stereo): Mono
PCM (integer format): TRUE
Bit (8/16/24/32/64): 16
Summary statistics for channel(s):
Min. 1st Qu. Median Mean 3rd Qu. Max.
0 0 0 0 0 0
I would like to save this file as a lower frequency file so that:
Samplingrate (Hertz): 8000
Is it possible?
I am trying:
savewav(silence,filename="silence0.5sec 8000.wav",f=800)
But it doesn't work - it saves the file but when I read it in,
Samplingrate is still 44100
What is savewav? At least not a tuneR function...
In "tuneR":
silence8000 <- downsample(silence, 8000)
writeWave(silence8000, file="silence0.5sec 8000.wav")
Best,
Uwe Ligges
