问题
I have the following code in python
from scipy.io.wavfile import read
rate, signal = read('./data/input.wav')
# get only one channel
signal = signal[:,0]
# do a bunch of processing here
Now I want to create an pydub segment using 'signal' and 'rate'
audio_segment = pydub.AudioSegment()
So how can I create this audio segment, and after that, how can I get back my signal as an numpy array?
回答1:
I was able to run this code on my machine:
from scipy.io.wavfile import read
from pydub import AudioSegment
rate, signal = read("./test/data/test1.wav")
channel1 = signal[:,0]
audio_segment = pydub.AudioSegment(
channel1.tobytes(),
frame_rate=rate,
sample_width=channel1.dtype.itemsize,
channels=1
)
# test that it sounds right (requires ffplay, or pyaudio):
from pydub.playback import play
play(audio_segment)
