New Features in Neutrino 1.8

Multiple markers

Neutrino 1.8 adds support for multiple markers per track. You can easily set up actions to trigger when playback reachers a particular marker.

Track Artwork

Add, view and edit artwork for your tracks. Features automatic syncing with iTunes' track artwork. Visualizers can access track artwork too!

A few other Neutrino Features

iTunes Integration

You've put a lot of time into collecting and organising your iTunes Library. Neutrino allows you to access all your playlists, tracks and tunes from the iTunes source.

Core Audio FXChain

Apple's Audio Units are the industry standard effects plug in format. There are literally thousands of AUs available, ready to use in Neutrino.

Per track settings

Unlike other players, Neutrino automatically saves effects, reverb, equalizer, visualizers and in fact all your settings on a per track basis. Or go global, it's up to you.

Quartz Compositions

Neutrino is one of the first apps to implement the Quartz Composer Music Visualizer protocol. Which means stunning animations which react to your music. Twenty included modules or create your own!

Independent time pitch

For musicians, the ability to slow down or speed up a track without altering pitch is a key to learning. For DJs, fine pitch or beat matching is essential. Neutrino makes it simple.

VideoCodex too...

Neutrino supports almost all media types, and does everything you expect from a player: full screen or windowed mode, track browsing, playlists, watched folders, and much more.

This software really hits the spot!
I have Protools HD and other top shelf audio software - but it is so much more convenient to do this kind of work from iTunes and in the formats of the files.
I never thought that my plugins could work on audio in compressed formats!
Very cool indeed!

One of the few shareware which REALLY worth the price! So stable, so well thought, so user friendly... My main guitar backing track player from now on.

Superb software. The people behind Neutrino are brilliant for replying to feature requests... No sooner had I requested a feature when, hey presto, it was incorporated into the new release! I could not have asked for more.
Neutrino is a joy to use. Highly recommended.



Simple interface, fast, great functionality, integrated with iTunes, reasonable price. What's not to like?



Ok, man, I just downloaded this to play with it, but it is absolutely STUNNINGLY awesome. Wow! Is all I can say. It may replace iTunes as my main player, especially if I want visualizations as well. Wow.



Simply fantastic. My favourite Player after iTunes. Everyone has to have this player on your own Mac.
