# Audio Spectrogram Generator Generate a spectrogram image from an audio file or a video audio track > Canonical page: https://elysiatools.com/en/tools/audio-spectrogram-generator - **Category:** Media - **Keywords:** audio, spectrogram, frequency, image, ffmpeg ## Overview Creates a PNG spectrogram with ffmpeg showspectrumpic to visualize frequency content over time. Audio files are supported directly; video files can also be uploaded and the first audio track will be used. ## Inputs - **Audio File** (file): Select an audio or video file - **Image Width** (text): e.g., 1200 - **Image Height** (text): e.g., 500 - **Color Scheme** (select) - **Show Legend** (checkbox) ## When to use - When you need to analyze the frequency distribution and noise levels of an audio recording. - When you want to extract the audio track from a video file and visualize its spectral density. - When you need to generate high-quality spectrogram images for audio mastering, sound design, or educational presentations. ## How it works - Upload an audio file (such as MP3, WAV, FLAC) or a video file (such as MP4, MKV) containing an audio track. - Configure the output image dimensions, choose a color scheme like Magma or Viridis, and decide whether to display the frequency legend. - The tool processes the file using FFmpeg's showspectrumpic filter to map frequencies over time. - Download the generated PNG spectrogram image showing the visual representation of your audio. ## Use cases - Analyzing audio recordings to identify background noise, hums, or specific frequency spikes. - Visualizing the frequency range of video soundtracks to ensure audio quality before publishing. - Creating visual assets of sound waves for music production portfolios, podcasts, or academic reports. ## Frequently asked questions ### What file formats are supported? You can upload common audio formats like MP3, WAV, and FLAC, as well as video formats like MP4 and MKV. ### How does the tool extract audio from video files? The tool automatically targets and processes the first audio track found within the uploaded video file. ### What is the purpose of the color scheme option? It changes the color palette (such as Magma, Viridis, or Fire) used to represent different frequency intensities. ### Can I display frequency and time scales on the image? Yes, enabling the 'Show Legend' option adds frequency and time axes to the generated spectrogram. ### What is the maximum file size I can upload? The tool supports audio and video file uploads up to 100 MB. ## Related tools - [Image Sequence to Video](https://elysiatools.com/en/tools/image-sequence-to-video): Convert uploaded image files or a ZIP archive of frames into a video, sorted naturally by filename - [Cover Art Embed](https://elysiatools.com/en/tools/cover-art-embed): Embed cover artwork without re-encoding media. - [Audio to Spectrogram Video](https://elysiatools.com/en/tools/audio-to-spectrogram-video): Create a video from audio with a spectrogram visualization - [Audio to Waveform Video](https://elysiatools.com/en/tools/audio-to-waveform-video): Create a video from audio with a waveform visualization - [Audio Waveform Generator](https://elysiatools.com/en/tools/audio-waveform-generator): Generate a waveform image from an audio file - [Data URI Generator](https://elysiatools.com/en/tools/data-uri-generator): Convert files into Data URIs (Base64 or percent-encoded) for inlining images, fonts, and assets directly into HTML, CSS, or Markdown - [Convert GIF to WebM](https://elysiatools.com/en/tools/gif-to-webm): Convert GIF images to WebM video format with modern compression and web optimization - [Low-CPU Video Preview Generator](https://elysiatools.com/en/tools/video-preview-generator): Create a preview montage from 5-10 evenly spaced video clips without re-encoding. ## Samples - [WebRTC Real-Time Communication Samples](https://elysiatools.com/en/samples/webrtc-samples): Comprehensive WebRTC samples for peer-to-peer audio/video communication, data channels, screen sharing, and signaling server implementation - [Bevy Game Engine Samples](https://elysiatools.com/en/samples/bevy-samples): Bevy Rust game engine examples with ECS, 2D/3D graphics, audio, and game mechanics implementations - [Copyright-Free FLAC Audio Samples](https://elysiatools.com/en/samples/flac-samples): Lossless FLAC audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Copyright-Free MP3 Audio Samples](https://elysiatools.com/en/samples/mp3-samples): Collection of royalty-free audio samples for testing and development purposes including nature sounds, meditation music, and ambient audio ## Related content - [Audio Analysis and Visualization Tools](https://elysiatools.com/en/hubs/audio-analysis-and-visualization-tools): Visualize audio, inspect stereo, diagnose signal and timing, and check files before delivery.
