Python中字符串格式化str.format的详细介绍
要实现变声,你可以使用PyAudio库提供的`effects`模块,其中包含了一些变声效果的函数,比如`chipmunk`、`robot`、`man`等。你可以在读取音频数据的时候,对数据应用这些变声效果。
下面是一个简单的实现示例,该示例将音频数据变成小矮人的声音:
```python
import pyaudio
from pydub import AudioSegment
from pydub.effects import speedup
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 16000
CHUNK = 1024
RECORD_SECONDS = 5
SPEEDUP_FACTOR = 2.0
p = pyaudio.PyAudio()
stream = p.open(format=FORMAT,
channels=CHANNELS,
rate=RATE,
input=True,
frames_per_buffer=CHUNK)
frames = []
for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
data = stream.read(CHUNK)
frames.append(data)
# 将音频数据转换为PyDub的音频片段
audio_segment = AudioSegment(
data=b''.join(frames),
sample_width=p.get_sample_size(FORMAT),
frame_rate=RATE,
channels=CHANNELS
)
# 变声
audio_segment = audio_segment.speedup(
playback_speed=SPEEDUP_FACTOR,
chunk_size=CHUNK,
crossfade=10
)
# 将变声后的音频片段转换回PyAudio可播放的数据
data = audio_segment.raw_data
stream.stop_stream()
stream.close()
p.terminate()
```
需要注意的是,这里使用了`pydub`库进行音频变声。在使用之前,你需要先安装它,可以使用以下命令进行安装:
```bash
pip install pydub
```
