Random Audio waveforms make testing them indeterminate

[obulat]

Problem

Currently, if the API does not return peaks for audio, we create an array of random values for the waveform. This makes it impossible to have visual regression tests for the audio detail page because the waveforms will always be different.

Description

We can use prng with a seed of audio id to make sure that each audio will always have the same waveform.

Implementation
