Audio Spectrogram Generator

Background

A podcast producer wants to check a newly recorded episode for low-frequency rumble and high-frequency hiss before editing.

Problem

The producer needs a quick way to inspect the entire audio spectrum visually without listening to the full hour-long track.

How to use

Upload the MP3 podcast file, set the width to 1600, height to 600, select the 'Viridis' color scheme, and check the 'Show Legend' option.

Outcome

A detailed PNG spectrogram showing the frequency distribution over time, making it easy to spot and target specific noise frequencies for filtering.

Background

A video editor is working on a short film and needs to verify that the dialogue track in an MP4 export does not clip or contain unwanted low-end rumble.

Problem

The editor needs to analyze the audio frequencies directly from the video file without manually extracting the audio track first.
