我想将 mp3 文件转换为 wav 16khz（这些是来自 Mozilla Common Voice 的文件）
我的功能
def one_sample(mp3_filename):
""" Take an audio file, and optionally convert it to 16kHz WAV """
if not os.path.splitext(mp3_filename.lower())[1] == ".mp3":
mp3_filename += ".mp3"
# Storing wav files next to the mp3 ones - just with a different suffix
wav_filename = os.path.splitext(mp3_filename)[0] + ".wav"
if not os.path.exists(wav_filename):
transformer = sox.Transformer()
transformer.convert(samplerate=SAMPLE_RATE, n_channels=CHANNELS)
try:
transformer.build(mp3_filename, wav_filename)
except sox.core.SoxError:
pass
我收到所有文件的错误：
