ggwave 0.4.2

功能

• 可听和超声波传输可用

• 8-16字节/秒的带宽（取决于传输协议）

• 鲁棒的FSK调制

• 基于Reed-Solomon的错误纠正

安装

pip install ggwave

API

encode(payload, [protocolId], [volume], [instance])

built-in function encode in module ggwave

encode(...)
    Encode payload into an audio waveform.
    @param {string} payload, the data to be encoded
    @return Generated audio waveform bytes representing 16-bit signed integer samples.

decode(instance, waveform)

built-in function decode in module ggwave

decode(...)
    Analyze and decode audio waveform to obtain original payload
    @param {bytes} waveform, the audio waveform to decode
    @return The decoded payload if successful.

用法

• 使用声音编码和传输数据

import ggwave
import pyaudio

p = pyaudio.PyAudio()

# generate audio waveform for string "hello python"
waveform = ggwave.encode("hello python", protocolId = 1, volume = 20)

print("Transmitting text 'hello python' ...")
stream = p.open(format=pyaudio.paFloat32, channels=1, rate=48000, output=True, frames_per_buffer=4096)
stream.write(waveform, len(waveform)//4)
stream.stop_stream()
stream.close()

p.terminate()

• 捕获和解码音频数据

import ggwave
import pyaudio

p = pyaudio.PyAudio()

stream = p.open(format=pyaudio.paFloat32, channels=1, rate=48000, input=True, frames_per_buffer=1024)

print('Listening ... Press Ctrl+C to stop')
instance = ggwave.init()

try:
    while True:
        data = stream.read(1024, exception_on_overflow=False)
        res = ggwave.decode(instance, data)
        if (not res is None):
            try:
                print('Received text: ' + res.decode("utf-8"))
            except:
                pass
except KeyboardInterrupt:
    pass

ggwave.free(instance)

stream.stop_stream()
stream.close()

p.terminate()
