Streamlined audio editor.

Overview

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.

Key Features:
  • Edit MP3, AAC, Apple Lossless, and AIFF files with no quality loss
  • Quickly split a long audio file into smaller files
  • Remove unwanted content, such as commercials, from your audio file
  • Re-arrange audio in a single file, copy audio from one file to another, or merge with a quick drag and drop
  • Create great-sounding MP3 or AAC ringtones for your cell phone.

What's new in Fission

Version 2.7.0:
  • Fission is now compatible with the newest Macs, the M1 Mac Mini, M1 MacBook Pro, and M1 MacBook Air.
  • 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.

Took A YEAR to fix the 'waveform drawing' UI bug introduced in 2.5.0 released Oct 2019 and not resolved until version 2.6.0 in Oct 2020. During that time, Fission was USELESS for editing, as the waveform would constantly display as a FLAT line, forcing user to constantly change magnification or resize the windows to force display to update. I was forced to move on and started using Amadeus and Audacity. Falling back to an earlier version of Fission was not option because prior versions did not support Catalina. These recent improvements since 2.6.0 have not won me back or restored my confidence in their development process. If the company wishes to win me back as a user they will need to do more than pretend like 'business as usual' and acknowledge what happened during that YEAR of no updates and no fixing of a show-stopper bugs.

I attempted to download Fission but got some kind of php file. When I double clicked that file, I got a message saying Xcode needed to install something. This link might be a scam.

To compress a FLAC file size, a professional FLAC compressor - Avdshare Video Converter is recommended to use.

Single waveform for stereo files? Deal breaker.

I really appreciate simple apps which aren't full of bloatware. Fission is such an app—perfect for editing and batch converting for the non-professional (and maybe pros too!?) I'm sure there are audio editing apps with lots more features, but the simplicity of Fission is what wins my praise

Great for quick lossless audio trimming and turning snippets into iPhone ringtones too. I bought this app when it first came out in 2006, bought the v.2 update five years ago(!) and am happy to see that they are still thinking of it, supporting 32-bit files. It's an app I only need to use occasionally, but it's solid and does its job.

Fission is one of the best apps I have ever bought! It makes editing audio easy and painless. I don't write many reviews but I do want to help spread the word.
