```
    convertToBuffer:error:withInputFromBlock:
    Perform any supported conversion.
    It attempts to fill the buffer to its capacity. On return, the buffer's length indicates the number of sample frames successfully converted.
    
    Parameters:
    
    inputBlock - A block which will be called to get input data as needed. See description for AVAudioConverterInputBlock.
    
    outputBuffer - The output buffer.
    
    outError - An error if the conversion fails.
    
    Returns:
    
    An AVAudioConverterOutputStatus is returned.

```
    convertToBuffer:fromBuffer:error:
    Perform a simple conversion. That is, a conversion which does not involve codecs or sample rate conversion.
    The output buffer's frameCapacity should be at least at large as the inputBuffer's frameLength. If the conversion involves a codec or sample rate conversion, you instead must use convertToBuffer:error:withInputFromBlock:.
    
    Parameters:
    
    inputBuffer - The input buffer.
    
    outputBuffer - The output buffer.
    
    outError - An error if the conversion fails.
    
    Returns:
    
    YES is returned on success, NO when an error has occurred.
