# SNR (Signal-To-Noise Ratio)

> Calculates a score based on the ratio between the desired signal power and background noise power in the audio.

<Note>SNR is a Statistical Metric</Note>

## Input

* **Required Inputs:**
  * **`output`**: URL of the audio recording to evaluate

## Output

* **`Result`**: Numeric SNR value (e.g., in dB)
* **`Reasoning`**: Brief explanation of audio quality assessment

## Interpretation

* **Higher values**: Clearer audio with less background noise
* **Lower values**: Significant noise interference impacting clarity

> SNR of 20dB indicates ***Good*** quality, while 5dB indicates ***Very Bad*** quality
