Open-Unmix vs RipX DAW

Open-Unmix is a PyTorch reference implementation for music source separation, aimed at researchers, audio engineers, and artists. Its ready-to-use models split pop music into vocals, drums, bass, and other instruments; a separate model, umxse, is for speech enhancement and was trained on the 28-speaker Voicebank+DEMAND corpus. Pre-trained choices include umxl, umxhq, umx, and umxse, with spectrogram variants also available. Each source model uses a three-layer bidirectional LSTM, a design the project says cannot run online or in real time. The code supports reproducing results, developing architectures, and adding data, while training is documented separately from the package. Install through pip or use the Docker container; pre-trained models can be loaded in Python or through torch.hub, and a Colab notebook supports online experimentation without local setup. The command line handles WAV, FLAC, and OGG, not MP3; stempeg can extend formats, including STEMS export. The software is MIT-licensed; umxl weights are non-commercial under CC BY-NC-SA 4.0.

RipX DAW separates mixed audio into layers that users can edit at note level, in a MIDI-like way. AI stem separation can split a track into vocals, bass, drums, guitars, instruments, and percussion, after which each layer can be edited note by note. Audio controls cover tempo, pitch, key or scale, effects, time-stretch, stereo panning, volume, and EQ. Built-in live effects include Reverse, Delay, Vibrato, Harmony, Formant Shift, and low- and high-pass filters. Users can print audio to MIDI for a VST or synthesizer, and export WAV, MP3, AIFF, or MIDI. RipX DAW PRO adds advanced harmonic editing, audio repair and cleanup, RipScripts, and RipLink plug-in integration. The app runs on macOS and Windows; the maker lists macOS 10.15 or later and 64-bit Windows 8, 10, or 11, with minimum hardware requirements of a 2-core 2.5 GHz CPU, 8 GB RAM, and 20 GB free disk space. A 21-day trial offers full PRO access without a credit card. Without a valid activation code, existing rips can be played, but new audio cannot be ripped.
