BeatMV AI Music Remixer vs StemForge

BeatMV AI Music Remixer has no write-up on Specifiction yet; its figures are above.

StemForge is a locally run, browser-based audio workstation for separating stems, extracting MIDI, generating audio, composing songs, mixing, and exporting. Demucs and BS-Roformer can separate audio into vocal, drum, bass, other, guitar, and piano stems; spectral analysis informs engine and model recommendations. For MIDI extraction, StemForge uses BasicPitch on instrument stems and faster-whisper with pitch tracking on vocal melodies. Its Synth tab generates text-conditioned audio with Stable Audio Open for up to 600 seconds, with optional audio or MIDI conditioning. Compose uses AceStep for song generation and RVC for voice conversion, with 14 built-in voices and a HuggingFace model browser. Mix combines stems, MIDI-rendered tracks, synth outputs, and composed songs; exports include WAV, FLAC, MP3, and OGG, individually or in a ZIP. The project says audio remains on the user's computer and no internet is needed after initial model downloads. Setup requires Python 3.12, FFmpeg, and FluidSynth with a GM soundfont. The software is free and open source.
