Audio creator - cut TfL announcements

Search the iBus library - Stops, Destinations, Routes and Originals (e.g. Morrisons, a terminus, a route number, or S_WESTCOMBE…). Load a file, drag a region on the waveform, then save. The trimmed clip uploads straight to your Audio library so you can pick it in the stops portal.

Merge timeline - join words into one clip

Example: load Bloomfield Road…, trim to just “Bloomfield”, press “Add selection to merge”. Then load a Crescent file, trim to “Crescent”, add it too. Tweak each part's trim inline (or press Trim to load it back into the waveform editor), set the gap or crossfade on each transition, preview the exact result, then save - and come back to tweak and re-save any time.

No parts yet - add selections with the button above, or “+ Merge” a whole file from the search results.
