# Audio source editor workflows
|
||
|
||
Phases 69–79 use the existing bounded mono WAV reader. Stereo input is downmixed;
|
||
these are offline control-thread tools, not stereo restoration or time stretching.
|
||
The project format remains 16. No new dependencies are required.
|
||
|
||
## Phase 69 — Source inspection
|
||
|
||
Select an audio clip and use View / Sample editor or double-click it. The modal
|
||
editor loads an independent snapshot of the complete source, up to 4,194,304 frames
|
||
(about 87 seconds at 48 kHz). Drag or enter half-open native frame bounds; zoom
|
||
1..64 and View start control the visible region. Statistics show raw mono min/max,
|
||
RMS and mean/DC before clip gain, fades or mixer processing. Display clamps to
|
||
±1; sample statistics retain finite over-range values. Editing project MIDI still
|
||
opens the piano roll. This editor does not audition or stream long files.
|
||
|
||
## Phase 70
|
||
|
||
Trim clip to selection applies source-frame endpoints within the current audible clip. Start rounds up and end rounds down to musical ticks; empty sub-tick ranges reject. Leading removal moves the timeline start by the same amount, preserving alignment. Source content, reference and clip gain/fade settings remain intact; project Undo restores the prior trim.
|
||
|
||
## Phase 71
|
||
|
||
Export selected frames writes a new mono float32 WAV of the half-open selection at native rate. Save full copy and relink writes the complete source and relinks only the selected clip after successful preparation. The original source is never overwritten. Full-copy adoption requires matching source frame count/rate. Project undo restores the reference but retains the new file, which may be referenced by redo/history or other projects. Failed adoption removes its owned new file. Export/copy runs synchronously outside audio callbacks.
