为什么会抛出 'sample width not specified' 错误？

Question

我正在尝试使用 wave 模块写入 Python 3 中的 wav 文件，但出现 'sample width not specified' 异常。这是为什么？

def write_sample(path, sample):
    """Writes a sample to a file at path location

    Arguments:
    path -- file path
    sample -- sample to be written 
    """
    with wave.open(path, 'w') as wave_file:
        # set up (make generic later)
        wave_file.setnchannels(1)
        wave_file.setsampwidth(16)
        wave_file.setframerate(44100)

        sample = struct.pack(f"<{len(sample)}h", sample)
        wave_file.writeframesraw(sample)

Answer 1

已解决，将 .setsampwidth 方法误读为 n 是位，而不是字节

为什么会抛出 'sample width not specified' 错误？

Why is the 'sample width not specified' error being thrown?
