This is known as an audio wave or a sound wave. To interpret and work with sound, humans came up with the visual representation of waveforms. The traveling wave represents the movement of sound through the air, in time. It's a form of data visualization that captures sound waves. A single waveform has an X-axis and a Y-axis.

The Waveform Audio File Format (WAV) is an audio file format. It is considered a "first-generation" format with no compression except with some manipulations in order to store the sound digitally, resulting in larger sizes compared to formats like MP3 and WMA. This standard was developed by IBM and Microsoft for storing an audio bitstream on PCs. The Waveform Audio File Format is …

Usually 44100 samples (44.1 khz ). You can see that using 44 thousand pixels to represent one second of sound is not feasible, so divide total seconds by required waveform width. Take the result & multiply by 2 (to cover two bytes) and that is how you much you jump-&-sample the amplitudes as you form the waveform.

Waveform draw algorithm. PCM audio data is stored as a sequence of signal amplitude samples recorded at regular intervals. One second of the low-quality 8kHz audio consists of 8000 amplitude samples. To display every point of this fragment as is, you need at least an 8000-pixel wide display. I believe that such a screen resolution is still rare in 2021.

Waveform data is created in two steps: If you pass an ArrayBuffer containing encoded audio, the audio is decoded using the Web Audio API's decodeAudioData method. This must done on the browser's UI thread, so will be a blocking operation. The decoded audio is processed to produce the waveform data.

Although .wav is widely used when audio data analysis is concerned. Once you have successfully installed and imported libROSA in your jupyter notebook. You can read a given audio file by simply passing the file_path to librosa.load() function. librosa.load() —> function returns two things — 1. An array of amplitudes. 2. Sampling rate.

Audio file overview. The sound excerpts are digital audio files in .wav format. Sound waves are digitized by sampling them at discrete intervals known as the sampling rate (typically 44.1kHz for CD-quality audio meaning samples are taken 44,100 times per second).
