Classic Rock Covers is an audio or music resource for streaming, discovery, editing, production, or library management.
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.
fre:ac is a free audio converter and CD ripper supporting formats such as MP3, M4A/AAC, FLAC, WMA, Opus, Ogg Vorbis, WAV and others. It converts between supported formats, can rip audio CDs while querying the CDDB/GNUdb database for title information, and can be installed on a USB stick as a portable application.
A site for finding recently played songs, playlists and station history across SiriusXM, with searching tracks and browsing channels and options to listen on Spotify, Apple Music and YouTube. It also offers API documentation and plans: public endpoints are free, and an API key unlocks authenticated endpoints such as search and reports.
A basic tuner app written mostly in Kotlin. It detects pitch based on autocorrelation and FFT spectrum, improves accuracy by evaluating spectrum phase information and polynomial fitting, shows how pitch changes over time, and tunes to equal temperament. Settings include concert pitch, FFT window size, FFT window type and overlap. Licensed under GPLv3.
