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, key control across 12 semitones and speed from 50% to 120% while preserving pitch.
Mix audio online
Set volume, Mute and Solo for each stem, 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 FX to each stem and the master
Use vocal, guitar, bass, drum and master effects including amp, reverb, delay that follows the beat, 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, reverb removal, Lo Fi processing, loudness normalization at minus 14 LUFS, 48 kHz audio super resolution and four mastering styles. Export MP3, lossless WAV, stems or your exact mix.
Effects that stay in time with your song
AudioStem goes beyond downloading separated files. The effects studio is a Pro and Studio feature: hear it live while the song plays, then include EQ and FX for each stem in individual lossless WAV files and custom mixes. The effects follow the 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.
