The most reliable to quickly edit MP3, Lossless, WAV and AIFF files with no quality loss.

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

nice! it's quicky and simple, but wish it had more features like adding filters and effects to repair and enhance the audio file. would be great to have audio meters too!

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.
