Splitter Basics

Find your recordings in the Session Rack and learn how to open and manage them.

Main Tabs

After signing in, you can use Splitter to import audio and open recordings in the Session Rack, Classes for your courses and their folders, and Account for your allowances and settings. Log out sits at the right of the navigation. Lab members can work privately under Personal. Instructors set Listening Guy instructions under Account → Settings.

Account → Dashboard in an administrator account. Your allowances depend on your account.

Open a Recording

The Session Rack lists your newest splits first. When you open a recording, its mixer appears and the other recordings collapse to title rows. Their buttons remain available. Each status badge shows whether the recording is queued, processing, ready, or failed. When it reads READY, you can listen. A failed split does not count toward your daily allowance.

The Split actions menu open on a class recording, with Rename and Export, Copy link and Stop sharing, Open class, Add to class folder and Start sharing playback, and Delete

To rename your recording, you can click its title in the Session Rack, type a new title, and press Enter to save or Esc to cancel. You can also open the three-dot Split actions menu and choose Rename. The menu also groups Export and Move to My folders under Recording, Copy link and Stop sharing under Sharing, and, on a recording assigned to a class, Open class, Add to class folder, and shared playback under Class. See Export & Sharing for the download contents and sharing permissions.

Mixer Controls

At the top of the mixer, you can play or pause, move through the recording, see the time, and add a note. You can also change the speed without changing the pitch. Each stem has a colored label, a waveform showing the sound over time, Solo and Mute buttons, and a download arrow. Solo cycles through Front, Only, and the previous mix. See The Mixer for details.

The vertical line marks your place in the recording. Click a waveform or a note's timestamp to move to a passage. Use Refresh class notes to reload classmates' notes. Below them, click the Listening Guy header to open its guide and chat. See The Mixer for controls and keyboard shortcuts.

Folders

My folders, below the Session Rack, holds folders only you can see. Choose Move to My folders in Split actions to file a recording there. Expand a folder to see its recordings, choose Load all to open them in the Session Rack, or choose Rename. Folders a class can open are on the Classes page, where the app checks membership before access. On a recording assigned to a course, Open class in Split actions opens that course.

Resplit a Stem

At the end of a stem's row, you can choose the curved-arrow Resplit button to separate that audio again. Choose the number of stems and where to keep the result, then choose Resplit. Separate split creates another entry. For your own saved recording in the same workspace, With original split groups the result beneath it. Check the remaining allowance shown in the dialog before starting.

Delete or Hide

Open Split actions to find Delete for your own recording. For a recording owned by someone else, Hide removes it from your rack until your next visit. Download any stems you need before deleting your recording. Once the app accepts your request, it hides the split and blocks access. It then removes private content after any active processing finishes, while preserving audio still used by another split.
