Audio Trim & Merge & Slice

Audio Trim & Slice, also called TrimAudio, is an iPhone app for simple audio editing. Its waveform editor lets the user drag to select a region with precision of 0.01 seconds, see the playback position in real time and zoom in and out for accurate cuts.

Three core operations are provided. Trim keeps only the selected section, Slice Out removes unwanted parts such as noise, mistakes or silence and joins the remainder automatically, and Merge combines several clips into one file after reordering them by drag and drop. A project system saves edits so work can be resumed, and a clips library keeps reusable segments.

The app processes audio on the device and is available in several languages. It is distributed through the App Store by an individual developer as a free download with in-app purchases. It suits podcasters, students, musicians and anyone who needs quick edits to voice memos and recordings.
