Introduction

The Mic (Quarky Intellio) extension allows users to record and analyze audio using the built-in microphone of Quarky Intellio. It provides blocks and Python functions to record audio, save recordings, monitor sound levels, and stream microphone data.

Using this extension, you can:

  • Record audio using the built-in microphone.
  • Save audio recordings to a specified file.
  • Record audio for a fixed duration.
  • Record audio until the recording process finishes.
  • Save the recorded audio to the device’s flash memory.
  • Stop an ongoing recording.
  • Detect whether the microphone is currently recording.
  • Measure sound intensity using RMS values in decibels (dB).
  • Detect microphone volume levels for sound-triggered actions.
  • Stream live microphone data.

This extension is useful when creating voice recording applications, sound detection systems, noise-triggered automation, and audio-based robotics projects using Quarky Intellio.

PictoBlox Blocks

Start recording for seconds
This block starts recording audio to a specific file for the specified duration (in seconds) and saves the recording in wav or amr format.
Start recording for seconds until complete
This block starts recording audio to a specific file for the specified duration (in seconds) and saves the recording in wav or amr format. The recording continues until it is complete, and the script pauses until it finishes.
start recording file ( ) in flash for ( ) seconds
This block starts recording audio to a specific file for the specified duration (in seconds) and saves the recording in wav or amr format. The file is stored in the internal flash memory.
start recording to ( ) as ( )
This block begins continuous audio recording and saves the recording to the specified file in the selected wav or amr format.
Stop recording
This block stops the current audio recording and saves the recorded file.
is recording
This block reports whether the microphone is currently recording audio or not. It returns True or False and can display the value on the stage.
get RMS value in dB
This block measures the Root Mean Square (RMS) value of the sound signal and returns it in decibels (dB), representing the sound intensity
get volume
This block returns a simplified numerical value representing the current sound intensity detected by the microphone. It is useful for triggering actions based on sound levels, such as claps or loud noises.
mic stream ( )
This block starts or stops live microphone streaming, allowing the audio input to be processed in real time.
