Every change to ChunkAudio that you can see or use, newest first. Files still never leave your browser.
MP3 files of any length, split without re-encoding
Frame-exact MP3 splitting. MP3 files are now cut on frame boundaries by copying, the same way WAV is cut by bytes. A 7-hour recording splits in seconds, the parts stay MP3 at the original quality, and the old 2 to 3 hour memory limit is gone. Smart split still finds silences first, then cuts the original.
Each part carries the original tags and a proper length header, so players show the right duration and can seek.
Links in three guides pointed at addresses without the .html ending and returned 404; fixed, and such addresses now redirect.
Cut, remove pauses, go Pro
Cut a section. A second mode in the app: drag two handles on the waveform or type start and end times, preview the selection, then keep it or remove it. Sample-exact on WAV. Try it or read the MP3 cutter and audio cutter guides.
Trim silence. One button in cut mode places the handles at the first and last sound.
Remove pauses. A third mode finds long pauses inside a recording, shows them on the waveform, and shortens them to a length you choose. Free for recordings up to 10 minutes. Guide: silence remover.
ChunkAudio Pro. A one-time €24 licence: no ads, MP3 export at 192 or 320 kbps, pause removal on recordings of any length. Paid through Stripe, activated with a key, no account. Details.
M4A support explained. Voice Memos and Zoom recordings, what your browser can decode, and why the output is WAV: M4A splitter.
Long WAV files. WAV files of any length are split by copying bytes instead of decoding the whole file, which fixes multi-hour recordings that used to fail.
New look. Fresh design across the site, a shared header and footer, and an About page that says who runs ChunkAudio.
Small fixes. Dropped files are accepted by extension as well as type, and a rejected drop now says why.
