trakk'em vs Stacktune
Stacktune is built for the revision loop between engineer and client: level-matched, auto-aligned version compare and timestamped comments that turn into a checklist. trakk'em is built around the listen: whether each person played the mix, how much, from which device, which section they replayed, live, on a private link per person.

Why creators switch
What they heard, not only what they said
Comments tell you what the client noticed. The listen curve tells you where their attention actually went: replays, skips and how far they got, per person, before any note is written.
Live playing-now
See the listen happen in real time, with a marker gliding along the waveform as the client plays.
Delivery beyond the mix
Attachments, files sent back from the player, an embeddable player for your site and live streaming to a link, on the same account as your tracked links.
