Tone.Compressor is a thin wrapper around the Web Audio DynamicsCompressorNode. We'll do this by reducing the level of the loudest parts of the signal, then increasing the level of the whole signal by the same amount we reduced in the loudest parts. Applies compression, an equalizer emphasizing low and high mids, volume normalization plus highest-quality sample rate conversion. We train neural networks to impute new time-domain samples in an audio signal; this is similar to the image super-resolution problem, where individual audio samples are analogous to pixels.

The main idea of JPEG compression is to apply a specific transform to the image so that most of the coefficients of the transformed image are very small and can be cancelled out, thus gaining storage at the cost of very little visual degradation. Compression reduces the volume of loud sounds or amplifies quiet sounds by narrowing or "compressing" an audio signal's dynamic range. The typical goal of compression for voiceover is to increase the intelligibility of the quietest parts of the signal. A compressor reduces the volume of the loudest parts of an audio signal and levels out the overall volume variations (dynamic range) of an audio signal.
