EKO is a graphical sound editor built with Qt 6. It loads audio into memory and uses a 32-bit floating-point mixing and digital signal processing engine, with PortAudio providing access to recording and playback devices.
The editor works with numerous formats through libsndfile. It can also open MP3 files and extract audio from video with FFmpeg, while MP3 export is provided through an external encoder such as LAME.
This is public domain software.
