Frequency Modulation (FM) Audio Demodulator
https://www.vocal.com/video/fm-audio-demodulator/
A basic FM audio demodulator is shown in Fig.1. The RF FM audio signal is first down-converted to the baseband. The baseband FM signal is filtered in the main filter to attenuate adjacent channels and other out of band signals. Then, the CORDIC technique is …
FM Demodulation Detection: Frequency Modulation ...

FM demodulator circuits are found in any receiver that uses FM: broadcast receivers, two way radios like walkie talkies and handheld radios that use FM, and any receiver where frequency modulation is used. FM demodulation basics. In any radio that is designed to receive frequency modulated signals there is some form of FM demodulator or detector.

Play back an audio file after applying FM broadcast modulation and demodulation using System objects to process the data in streaming mode. Load the audio file guitartune.wav by using an audio file reader System object™ with the samples per frame set to 4410.
Demodulate broadcast FM-modulated signal - Simulink
https://www.mathworks.com/help/comm/ref/fmbroadcastdemodulatorbaseband.html
Description. The FM Broadcast Demodulator Baseband block demodulates a complex baseband FM signal by using the conjugate delay method, and filters the signal by using a de-emphasis filter. To demodulate stereo audio using 38 kHz, enable stereo demodulation. To demodulate RBDS signals from the 57 kHz band, enable RBDS demodulation.
