Contact maga40@naver.com with your Android and app versions. Avoid sending private recordings unless you intend to share them.

Import your audio

Use Android Files to import a source or a Slicevane1 project JSON. Buyer library starts empty. Supported sources: mono/stereo RIFF PCM16/24/32 or float32 WAV; uncompressed AIFF PCM16/24/32; MP3, M4A/AAC, FLAC or Ogg if the device system decoder supports them. AIFC, surround and RF64 are unsupported. Use 8–192 kHz, at least 32 frames, at most 20 seconds, 2 million decoded frames and 32 MiB original input. Original decoded sample rate and channel count are preserved. System codec delay or padding can appear in decoded frame counts, so compressed duration can differ from the container label. Use WAV or AIFF for sample-exact source boundaries.

Cut and audition

Choose amplitude-energy-rise candidates or equal 2/4/8/16 cuts. Every range is contiguous and has at least 32 source frames. Tap pads to select and hear actual processed audio, one at a time. Edit exact start inclusive/end exclusive frames, name, gain −18…6 dB, fade 0…10 ms and reverse. The project menu contains split, merge, rename and manual BPM 40…240. Undo holds 20 edits. The first start and final end stay at the source edges.

Preview and output share constant gain, linear edge fades, reverse and per-slice −1 dBFS sample-peak attenuation, then PCM16 quantization. No true-peak limiter, beat/tempo/key detection, recording, time stretching, effects or destination certification is provided. Source playback uses a PCM16 listening copy.

Save projects and files

Save explicitly to retain the source and cuts. Library supports 12 projects and 200 MiB of retained original sources, open, duplicate and confirmed deletion. Replacing unsaved work offers cancel, replace or save and continue. A source-bearing Slicevane1 Project.json from iOS or Android can be imported as a new project; limit 46 MiB JSON. Empty or invalid imports preserve current work.

Export creates N separate PCM16 WAVs plus six files: unchanged Source, Original-timing.mid, Cuts.csv, Project.json, Cut-proof.pdf and Readme.txt. MIDI format 0, PPQ960, channel 10 and notes 36 onward. Its onsets and durations follow original source frames, rounded to nearest MIDI tick using the stored manual tempo. Map those note numbers to WAVs yourself. View the real PDF or save ZIP and individual files through Android Files. Saving does not verify recipient delivery.

Recover local work

Failed atomic index writes keep prior committed projects. An unreadable, missing or changed saved project blocks normal saving and package export. Save recovery ZIP before resetting library links. Reset retains project files until explicit unused-file cleanup; it clears library links and open edits. Recovery ZIP is a raw preservation copy, not automatic repair. Extract individual readable project JSONs and import them. Confirmed unused-file cleanup removes only unreferenced private project files and temporary exports. Keep original and external copies before deletion or uninstalling.
