KIMIX v1.0

Project Overview

KIMIX v1.0 is a desktop audio platform built around a listening-first workflow with a full editor available as a power mode.

Core architecture:

Now Playing: immersive playback UI
Playlist: local/featured library browsing, queue-style playback, favorites, share/copy track info
Editor: multi-track, timeline-based audio editing and export

Tech stack:

Python 3.11/3.12
PyQt5 (GUI + multimedia)
pydub (audio processing/export)
simpleaudio (editor playback)
sounddevice + numpy (microphone recording)
