Mp3 Fast Cutter & Joiner

The fastest way to cut, join and split MP3 files, and the sound stays bit-for-bit original.

Mp3 Fast Cutter & Joiner works directly on the MP3 frames instead of decoding and re-encoding your audio. The cut is instant, the quality never drops, and the file you save is still an MP3. It is made for audiobooks, podcasts, lectures, DJ mixes and long recordings, as well as everyday songs.

Open a file, drag two handles, listen and save. Joining is just as simple: pick the files, put them in order and tap Join.

LOSSLESS CUT
• No re-encoding: the audio frames are copied exactly as they are, so a three-hour file is cut in about a second.
• MP3 in, MP3 out. The app never quietly converts your file to M4A or another format.
• Keep the selection, or remove it and keep everything else.
• Works on very long files: a 10-hour audiobook opens with an instant waveform built from the frame index, while the precise waveform loads in the background.
• Supports MPEG-1, MPEG-2 and MPEG-2.5 Layer III, both CBR and VBR.

JOIN MP3 FILES
• Pick as many files as you need and drag them into the right order.
• Files with the same format are joined losslessly and instantly.
• Smart join (Pro) handles mixed files: different sample rates, mono and stereo, even M4A or WAV. They are decoded and re-encoded into one clean MP3.
• Ideal for putting the chapters of a book or a series of podcast episodes into one file.

MULTI-CUT AND SPLIT
• Multi-cut (Pro): keep or remove several parts in one pass, for example every ad break in a podcast episode.
• Split into equal parts, or every N minutes.
• Split at silences (Pro): the app finds the pauses between chapters or songs and splits there, with a threshold and minimum silence you can adjust.
• Split by chapters (Pro) using the chapter marks inside the MP3 or a CUE sheet.
• Parts are named automatically, such as "Book – Part 03", and get track numbers so they play in order.
• Batch queue (Pro): apply one rule to many files at once. Trim the same intro from every episode, trim the end, split every N minutes or split at silences.

PRECISE
• Handles snap to MP3 frames of about 26 ms, which is what keeps every cut lossless.
• Nudge the start or end by one frame at a time, or type an exact time.
• Zoom into the waveform to place a cut between two words.
• Loop preview plays exactly what will be saved before you save it.

KEEPS TAGS AND COVER
Title, artist, album and cover art are carried over into every output. Each saved file gets a fresh header, so the right length shows in every player, even for VBR files and joined tracks.

ALSO
• Files are saved to Music/Mp3 Fast Cutter and listed under My files.
• Share a result straight from the app.
• Short tips guide you through the first cut and can be shown again from Settings.
• Set a cut as your ringtone, notification sound or alarm.
• Uses the system file picker, so it finds every MP3 on your phone or SD card, without asking for storage permission.

PRIVACY
Everything happens on your device. No file is uploaded, no account is needed, and your recordings stay yours.
