DDP Player

Starts at 00:02:00. Red Book puts two seconds of silent lead-in before track 1, which a CD player never plays. Transport controls land on the track start, as a real player would — the shaded head of the overview is that silence.

Reference listening. Timings, order, spacing and levels are exact. Playback is 44.1 kHz with no resampling, though your output device may still convert.

Structural checks only. These test the PQ data and audio image against the limits in IEC 60908. A fileset cannot tell you everything — lead-in, subcode interpolation and whether an ISRC's registrant code is really registered are all outside it. Zero-length pregaps between tracks are legal and are not flagged.

Nothing leaves this machine. The fileset is read with the browser's local File API and decoded in the tab. There is no upload, no server, and no copy made.
