from pathlib import Path
import soundfile as sf  # for reading audio
import dfpwm

data, sample_rate = sf.read('./someaudio.mp3')  # read audio

# If sample rate is not 48000, may get strange result
# use `dfpwm.resample(...)` to resample
if sample_rate != dfpwm.SAMPLE_RATE:
    raise ValueError(f"{sample_rate} != {dfpwm.SAMPLE_RATE}")

if len(data.shape) != 0 and data.shape[1] > 1:
    data = data[:, 0]  # get channel 0

dfpwm = dfpwm.compressor(data)  # convert
Path('out.dfpwm').write_bytes(dfpwm)  # write result to file
