More than an AI stem splitter: a complete browser audio studio
Keep one track open from upload to finished export. The synchronized player, practice controls, stem mixer, song analysis, effects and mastering tools all work on the same separated audio.
Practice with synchronized stems
Play, seek, mute, solo and loop a difficult section. Pro adds automatic BPM and live chords. Studio adds an Auto Metronome, ±6-semitone key control and pitch-preserving 50–120% speed.
Mix audio online
Set per-stem volume, Mute and Solo, shape each part with a 10-band equalizer and 13 presets, then save custom EQ presets and build a complete custom mix in the browser.
Add per-stem and master FX
Use vocal, guitar, bass, drum and master effects including amp, reverb, beat-synced delay, drive, chorus, wah, octaver, compression, stereo width and limiting.
Analyze BPM, chords and MIDI
Follow the detected tempo and current or upcoming chords during playback. Chord names transpose with your practice key. Pro and Studio can export MIDI from one stem or the full mix.
Clean, master and export
Studio adds AI denoise, de-reverb, Lo-Fi processing, −14 LUFS normalization, 48 kHz super-resolution and four mastering styles. Export MP3, lossless WAV, stems or your exact mix.
Song-aware effects that stay with your mix
AudioStem goes beyond downloading separated files. Every plan can preview the complete effects studio live. Pro and Studio can bake per-stem EQ and FX into individual lossless WAV files and custom mixdowns. Beat-synced effects follow detected BPM even when practice speed changes.
Vocals
Hall, room and plate reverb, slapback and ping-pong delay, doubler, pitch, drive, filters and ring modulation.
Instruments and drums
Guitar amp and modulation, bass compression and octaver, plus drum punch, gated rooms and filter sweeps.
Master bus
Stereo width, glue compression, limiting, Lo-Fi and reverb for the complete mix.

- Choose a separation model. Split the song into the vocals, instruments or drum parts you need.
- Practice and remix. Play synchronized stems, loop a section, follow chords, change key or speed, mix, EQ and add effects.
