Audio recording

The audio recording extension lets you record and play back audio with the micro:bit. If your version of the micro:bit has a microphone you can record a brief amount of audio and play it back on the speaker or at a sound output pin. Audio that you record is stored in an audio buffer and can be played later or recorded over with new audio.

Works with micro:bit V2

Using these blocks requires the micro:bit V2 hardware. If you use any blocks that attempt access flash memory on a micro:bit v1 board, you will see the 927 error code on the screen.
