Music and audio tools that install from the browser

Short answer

AudioMass is a full waveform editor that runs in a tab — trim, fade, apply effects, export, with no upload and no account. Mixxx covers DJ mixing, BitMidi holds a large MIDI archive, and Radio Garden lets you listen to stations by spinning a globe. Bandcamp works as an installed app for anyone who buys music rather than streams it.

Editing audio in a tab

AudioMass is the strongest entry here: a waveform editor with trimming, fades, normalisation and effects, running entirely in the browser. It keeps working with no connection, and the file you open never leaves your machine.

For a quick trim of a voice memo or a podcast segment, it removes the whole step of finding, installing and licensing a desktop editor.

Playing and mixing

Mixxx covers DJ mixing — decks, crossfader, beat detection — and works offline once installed. BitMidi holds a large archive of MIDI files and plays them in the browser, which is a small pleasure and an occasionally useful one.

Radio Garden is the one people keep: a globe you spin to hear live radio from wherever your finger lands.

Libraries and listening

Bandcamp works well installed for anyone who buys music rather than renting it — the collection, the player and the discovery feed all behave like an app once it has its own window.

Spotify Release List is narrower and useful: it tells you what the artists you follow have actually put out, which the streaming apps bury.

Frequently asked

Can a browser really edit audio?

Yes — the Web Audio API has been capable for years. AudioMass does waveform editing with effects entirely client-side; the limit is very long files, where memory becomes the constraint.

Do these work offline?

The editors and tools generally do once installed. Anything that streams — radio, a music library — needs the connection by definition.
