The main window

The main window groups file identity at the top, monitor selection in the middle and the shared transport below.

Application header

The VinylRest ABC Player icon and name identify the application. The subtitle states its purpose: sample-synchronized A/B/C audio comparison.

A · Source and B · Cleaned file cards

Each card displays the role, filename, sample rate, channel layout and duration. Use Choose A · Source or Choose B · Cleaned to replace one side of the pair.

The labels describe the listening experiment: ABC Player does not inspect the restoration history. You decide which file is the original and which is the processed result.

Monitor buttons

A Source
Audible gain is applied only to the original A path.
B Cleaned
Audible gain is applied only to the processed B path.
C Difference
A is mixed at +1 and B at −1, producing the live A − B signal.

The selected monitor is turquoise. Inactive controls remain visibly outlined. Selecting another monitor changes gains only; it does not restart either audio player.

Shared transport

Play / Pause
Starts both files together or pauses them at the same frame. Resuming continues from that shared position.
Stop
Stops playback and returns the shared playhead to the beginning.
Scrubber
Drag to seek both files to the same timeline position.
Time readout
Shows the current position and total duration.
Format readout
Confirms the active pair’s sample rate and mono/stereo channel layout.
