TrackScope

Watch every track at once. Put TrackScope on the tracks you care about and a single window shows all of them together — with the names already set in Logic Pro, and a colour of its own for each track.

Hear it. See it. Fix it.

TrackScope's Spectrum view. A sidebar lists twenty-five tracks from a rock session — kick, snare, hi-hats, toms, overheads, two guitar amps, organ, room and summing busses — each with a colour and an on/off switch. The graph beside it draws all of them at once as overlaid coloured curves running from 10 Hz to 20 kHz, so the tracks competing for the same frequencies can be seen against each other rather than one at a time. — Twenty-five tracks in one window, which is the whole point — the sidebar is the session, and every curve on the graph is one of its tracks.

Why it's different

Not one meter on your master — every track, together.

Most analyzers show you one channel. To compare two parts you open two windows, and to compare eight you give up. TrackScope instances talk to each other inside Logic Pro, so whichever window you open shows every track you have inserted it on — selected track in front, the rest drawn behind it for context.

You can add it to a whole mixer's worth of channels in one go: select the strips, then hold Option + Shift while choosing it from an insert slot. The same trick takes them all off again.

Four ways to look at the same tracks.

Spectrum

The selected track drawn as bars, every other track behind it as a thin coloured outline.

You can see the bass and the kick fighting for the same space without soloing either one.

Phase

A correlation meter for each track you are watching, and a goniometer for the one you have selected.

Flags the stereo widener that may thin out or drop when somebody plays it in mono — a reason to check the track in mono before somebody else does.

Dynamics

Loudness and peaks for each track across the length of the song, with crest figures.

Shows which parts you have already squashed flat, and which still have life in them.

Spectrogram

The whole song as a frequency heatmap, one per track.

Rumble, room resonances and two parts sitting on top of each other all show up as shapes.

TrackScope's Phase view. A correlation meter for each track runs down the middle of the window: most read 1.00 in green, meaning the two channels agree, while a room track reads minus 0.31 in red and two others sit part-way at 0.11 and 0.17. On the right, a goniometer plots the selected track as a scatter cloud leaning along one diagonal. — The meter reading −0.31 in red is a room channel whose two sides are fighting each other — the kind of thing that can lose level or disappear when the mix is played in mono, and worth a listen in mono before it ships. Green is agreement; the goniometer on the right is the selected track alone.

Release status

TrackScope is still in development. There is no build-it-yourself route and no buy button — it will be sold, with a signed installer, once it is finished, and not before.
