Audio Editor & Tool is an audio editor app for iPhone and iPad.
Cut, trim, insert silence, insert a file, separate to vocal and accompaniment, add effects. Then, export the file.
Notes & Tips:
Import File
Can import only non-DRM files
An imported file is converted to PCM/44.1kHz/32bit float
Supports Mono/Stereo audio
Edit
Edit a single waveform
Cut/Trim for selected time
Insert a silence at the beginning, the end, or arbitrary time for max 30 seconds
Insert a file at the beginning, the end, or arbitrary time
Source Separation
Separate source to vocal and accompaniment
Do not expect to be perfect
Separation takes some time, but should be performant; this app uses CoreML
Inserting a second of slience at the beginning and the end might improve the separation
Source separation might work as a noise reduction; separating to voice and other sounds (i.e. background music, noise, ... etc.)
