Amplitude Scale 'Y-axis' for Audio Annotation

**Is your feature request related to a problem? Please describe.**
When annotating audio data, there is no visible 'y-axis' scale representing amplitude. Without an amplitude reference, it is challenging to compare signal intensities and potentially introduce bias in label choices when scaling up/down the waveform height.

**Describe the solution you'd like**
I would like a y-axis scale for amplitude when annotating audio data. This scale should be clearly visible alongside the waveform and allow users to interpret amplitude values more accurately as they go through and annotate audio data. Ideally, it should support both linear and logarithmic (dB) scaling for different use cases and be togglable.

**Describe alternatives you've considered**
- Estimating amplitude levels visually and presetting the 'defaultScale' value, which is imprecise.
- Using external tools to measure amplitude separately and then cross-referencing within the software, which is inefficient.

**Additional context**
An amplitude scale would be beneficial for various applications. If possible, adding customization options (e.g., adjusting scale range or toggling between linear and dB views) would further enhance usability.
