In this lab, we will create a realtime audio spectrogram.A spectrogram provides a visual time-history for the frequency content of a signal. They are extremely interesting in that they provide us with a way to look at sounds (and other signals) in a way that our brains can comprehend.

Per track Spectrogram Settings It is possible to temporarily change the Spectrogram settings for a particular Spectrogram track by opening the Audio Track Dropdown Menu on the Spectrogram track you want to change, then choose Spectrogram Settings. This opens a dialog similar to Spectrograms Preferences with the same settings available. Image to Audio, Spectrogram Player This app allows you to convert an image to audio file, and Decode, Play a audio file via spectrogram. You can make a sound image that is viewable on a spectrogram. With this app you can convert your images to audio and secretly send them to others. In Audio_Spectrogram.cpp the parameterization can be seen for a microphone input signal of 44.1 kHz sampling frequency with mono channel.

This toolbox is provided as Matlab source code. Audio Spectrograms Since classic spectrograms [] typically show log-magnitude intensity versus time and frequency, and since sound-pressure level in dB is roughly proportional to perceived loudness, at least at high levels [179,276,305], we can say that a classic spectrogram provides a reasonably good psychoacoustic display for sound, provided the window length has been chosen to be comparable
Create an audio spectrogram A spectrogram is a visual representation of the spectrum of frequencies in a sound or other signal as they vary with time or some other variable. Spectrograms are sometimes called spectral waterfalls, voiceprints, or voicegrams.

The Pan-Specific View adds another dimension to the Spectrogram, that Drill Fault Diagnosis Based on the Scalogram and Mel Spectrogram of Sound Signals Using Artificial Intelligence. IEEE Access, vol. 8, ss. 203655-203666. Thim Sökning: "Spectrogram".
The spectrogram is a concise ‘snapshot’ of an audio wave and since it is an image, it is well suited to being input to CNN-based architectures developed for handling images. Spectrograms are generated from sound signals using Fourier Transforms.
