Wav2vec2.0, as the name already suggests, claims to receive a raw audio file in its waveform and convert it to a vector (encode it in the latent space). Therefore, many downstream tasks can be performed on top of this vector representation extracted by the model. Meta claims that using …

In this blog post, I'll be diving into some concepts of digital signal processing (DSP). Most of them I had to learn before starting to work with models that take audio files as input and therefore, require some preprocessing steps.

The concepts I'll briefly discuss here are:
1. Fourier transforms …
