    Is there a simple circuit which converts a tone 'heard' by a microphone into an analogue voltage. The microbit will take analogue voltages between 0v and 3.3v DC.
    Alternatively if an i2c device exists that would make the solution neat i can write a micropython class for devices. Microbit also supports the uart protocol and the spi protocol

    Thanks in advance

    That's what a microphone does: convert acustic waves into an electric signal. You'll have to amplify the signal by a microphone (pre-) amplifier to get a useful signal level. What kind of amplifier you use depends on the type of microphone.
    You can buy microphone+amplifier as a kit.

    Or, as you suggested, use an I²C based Mems microphone.
