Acoustic Spectrum Analyzer

Acoustic Spectrum Analyzer is a web tool that lets users upload audio files and visualize their frequency spectrum. It supports formats such as MP3, WAV, FLAC, M4A and OGG, with adjustable FFT size, window function, frequency scale and export format. Some formats use native header parsing for sample rate detection, while others rely on browser AudioContext fallback that may resample audio.
