1.Recording Audio(record)

1.1 sound_level()¶

1.2 record()¶

1.3 start_record()¶

1.4 stop_record()¶

Example Description¶

In this simple example, our main goal is to use the functions in the previous text to measure the volume of sound, record the sound, start and end the recording.

Hardware Required¶

• UNIHIKER

Example Code¶

First, instantiate an object of the Audio class within the UNIHIKER class. Then, use this object to call the audio = Audio() function to initialize the pins for recording audio. Once initialized, proceed to collect ambient sound volume 30 times within a loop. Following this, utilize the audio.record() function to capture a three-second audio clip. Finally, manage the recording process using the audio.start_record() and audio.stop_record() functions.

from unihiker import Audio
import time

audio = Audio()  # Instantiating audio

print("Ambient sound size")
for i in range(30):
    print(audio.sound_level())
    time.sleep(0.1)


print("Record for 3 seconds")
audio.record('3s.wav', 3)  # Record for 3 seconds and save to file 3s.wav

print("start recording")
audio.start_record('6s.wav')  # Start recording in the background and save it to file 6s.wav
print("Wait for 6 seconds")
time.sleep(6)  # Wait for 6 seconds
audio.stop_record() # stop recording
print("stop recording")
