Split Audio into Parts, Every Way: Silence, Chapters, Fixed Length

Every way the free Audio Splitter cuts, on one 1:33 recording holding three takes: equal parts (three pieces of 0:31.2, each a byte copy of the original — 610 KB, nothing re-encoded, one ZIP), fixed length (30 s makes four, the last keeps 0:03.6), silence (the defaults find 24 gaps — every breath; a 2-second minimum gap finds exactly the three takes), and a pasted chapter list that names each piece, with a filename pattern. Choosing M4A re-encodes, and the tool says so. Nothing is uploaded.

The Audio Splitter, every mode, on one recording that holds three takes — a voice note, a studio take and a meeting, 1:33.6 in all. Equal parts: three pieces of 0:31.2, and every piece is a byte copy — the original’s own MP3 frames written into new files, 610 KB each, nothing re-encoded — downloadable one by one or in a single ZIP. Fixed length: 30 seconds makes four pieces, the last keeping the 3.6 s that is left. Silence: at its defaults (-35 dB, 0.7 s) it finds 24 gaps — every pause for breath — and 13 pieces; raise "Gap at least" to 2 seconds and it finds only the breaks between the takes: three pieces, each cut in the middle of the break. Chapters: paste a time and a name per line and each piece takes its name; the filename pattern {n} - {title} makes "1 - Voice note.mp3". Choosing M4A re-encodes and says so; MP3 for an MP3 stays a byte copy. Free splits one file up to 50 MB and 30 minutes into 20 pieces; Pro takes 25 files and 500 pieces. Nothing is uploaded.
