Fission can crop and trim audio, paste in or join files, or just rapidly split one long file into many. It’s streamlined for fast editing. Plus, it works without the quality loss caused by other editors, so you can get perfect quality audio even when editing MP3 and AAC files.
If you need to convert formats, Fission can do that too! You can rapidly export or batch convert files to the MP3, AAC, Apple Lossless, FLAC, AIFF, and WAV formats.

Initial Support for M Chip-Based Macs
Fission is now a Universal app, offering initial support for the new M1 chip-based Macs.
Fission now respects the user-specified system-wide “Accent” color on MacOS 10.14 (Mojave) and up. It also supports Big Sur’s new “Multicolor” option, with an appropriate, app-specific gold.
Fission now shows sample rates in Hz, rather than kHz, for consistency across all Rogue Amoeba apps.
