## bark_mel_erb.jpg

The image is a graph that displays four different frequency scales: ERB (Equivalent Rectangular Bandwidth), Mel, Bark, and Linear. The x-axis represents Frequency in Hertz (Hz) on a logarithmic scale, ranging from approximately 10 to 100,000 Hz. The y-axis represents Normalized Scales.

The graph shows four distinct curves corresponding to each frequency scale:

- **ERB**: This curve starts at the bottom left and rises gradually as it moves towards higher frequencies.
- **Mel**: This curve also begins near the bottom left but rises more steeply than ERB, especially in the lower frequency range. It then levels off slightly before continuing its rise.
- **Bark**: This curve is similar to Mel but starts at a slightly higher point on the y-axis and has a steeper initial slope, indicating it increases faster with increasing frequency compared to both ERB and Linear scales.
- **Linear**: This curve is a straight line that rises steadily from left to right. It indicates a linear relationship between frequency and scale.

The legend in the lower-left corner identifies each of these curves by name: ERB (blue), Mel (orange), Bark (yellow), and Linear (green). The graph does not contain any people or characters, only data representing different frequency scales.
