Audio Offline Renderer – User Manual

1. What AOR Does
Audio Offline Renderer is a focused editor for full-file audio work without opening a DAW session.
You can trim, shape fade-in/fade-out, pan-flip stereo, embed metadata, and create watermark variants in one render package.

2. Quick Start (Core Workflow)

  1. Click Load File (or drag audio into the main waveform area).

  2. Set trim, fades, and optional pan flip.

  3. (Optional) Enable Add Audio Watermark and choose Random White Noise or Custom File.

  4. Fill metadata fields.

  5. Click Render, choose destination folder, and AOR creates a render package.

3. Top Header Controls

  • Load File: opens source audio.

  • File name: output stem (base file name for rendered files).

  • Render: opens destination-folder picker and runs render.

  • Light-bulb button: global tooltip toggle for all control hints.

  • HOW TO: short in-app quick guide.

  • ABOUT: product/about overlay card.

  • Window title includes version (example: v1.1).

4. Zoom / Navigation Row (Main Waveform)

  • Pointer icon: normal edit mode (trim/fade/playhead/watermark handle editing).

  • Magnifier icon: zoom mode.

  • <: jump visible range to trim start side.

  • -: zoom out.

  • +: zoom in.

  • >: jump visible range to trim end side.

  • 1:1: reset full-view zoom.

  • x.x label: current zoom ratio.

  • Extra gestures:

    • In zoom mode, click = zoom in; Alt+click = zoom out.

    • Mouse wheel = horizontal pan.

    • Cmd+wheel = cursor-centered zoom.

5. Transport + Keyboard

  • |< jump to trim start cursor position.

  • << hold to shuttle rewind.

  • > play from current red playhead.

  • || pause.

  • >> hold to shuttle forward.

  • >| jump to trim end cursor position.

  • Keyboard: Space toggles play/pause, Left/Right Arrow shuttle rewind/forward while held.

6. Trim + Fade Editing

  • Trim start / end fields: enter exact seconds.

  • You can also scrub these values by clicking field and dragging left/right.

  • Main waveform trim handles: orange edge flags.

  • Fade endpoint handles: near trim edges.

  • Fade shape top dots: drag to change curve shape/exponent.

  • Left/Right fade panels (Fade In / Fade Out) include:

    • OFF toggle (enables/disables actual fade processing).

    • Preview In / Preview Out button (toggle stop/play preview).

    • Preview window - [seconds] + (default 3s).

    • Mini panel zoom - / + (time zoom for that side panel).

    • Vertical slider = waveform amplitude scaling in that side preview panel.

7. Pan Flip

  • Pan Flip swaps left/right channels in the render output.

  • Visual channel orientation also flips in main and side previews.

8. Add Audio Watermark (Detailed)
Turn on Add Audio Watermark to create watermark render variant.

A) Random White Noise mode

  • Count: number of watermark placements (1..64, default 5).

  • Length ms: per-placement duration (20..10000, default 700).

  • vol (0..127): watermark level step mapped internally to approx -60 dB .. -6 dB.

  • You can reposition watermark masks directly in waveform using white handles:

    • Drag body/bottom grab handle to move placement.

    • Drag left/right white edge lines to resize placement.

    • Drag center dot on mask line up/down to adjust watermark level.

  • Placements stay inside trim region.

B) Custom File mode

  • Enable Custom File, then Browse... or drag/drop an audio file into the custom watermark preview lane (Drop audio here).

  • > button previews only the watermark clip.

  • Norm normalizes custom clip gain (peak-target workflow).

  • count (right of Norm) controls number of custom watermark placements (default 5).

  • Inside custom clip editor:

    • Edge vertical lines = trim start/end of watermark clip.

    • Top dots = fade-in/fade-out of watermark clip.

    • Center dot up/down = custom clip gain (-24 dB .. +24 dB).

  • In custom mode, random-noise controls are dimmed/disabled.

  • Placement resizing is shrink-oriented to keep mask tied to effective custom clip duration.

9. Metadata Section (All Fields)
AOR currently exposes 10 fields:

  • ISRC: International Standard Recording Code (validated; bad format blocks render).

  • Title

  • Artist

  • Album

  • Year

  • Genre

  • Composer

  • Publisher/Label

  • Copyright

  • Comment

10. Render Package, Naming, Recall

  • Destination folder created as: <SourceName> Rendered.

  • If that folder already exists, AOR auto-creates numbered folder variants.

  • Output naming includes edit tags in parentheses when applicable (example: (fadein_fadeout_trim)).

  • Package includes:

    • Processed audio file

    • Watermark variant file (if watermark enabled)

    • .edits.txt summary

    • .session-recall.oarsession recall file

  • Success dialog contains clickable folder path link to open location immediately.

  • Opening a recall file restores session state; if source audio moved, AOR asks you to relink it.
