The FFMPEG Way To Deal With Your Audio: Extract - Waveform - Spectrogram - High/Low Pass Filters
In this video we deal with audio: we use ffmpeg to manage and record an audio stream using an audio input device available in the system.
We also use ffmpeg to produce the audio waveform as a single image and as video, also we see how to produce the spectrogram.
In the end, we also use the low pass and the high pass filters to cut out the frequency respectively above and below the given frequency.
For any questions or doubts, feel free to write a comment down below!
