From stems to your finished mix.

Stem mixing available now

Instrument mixing

Role-based high-pass filters, EQ and compression. Slow automated panning for guitar, piano and other instruments; bass and kick locked to center.

Vocal shaping & adjustable fades

Up to 16 layers, adjustable 2,000 Hz EQ, word-protected breath-like noise reduction, and adjustable 1–20 ms fades at detected vocal boundaries. Subscriber fade controls default to 2 ms; your choice is remembered on this device.

Piano envelope

Gentle envelope shaping smooths piano peaks without shortening the performance. Keep your timing and musical feel.

Listen and export

Compare your mix, export 320 kbps MP3 or stereo WAV, and save the preset and edit report. Files are processed on your device.

Video audio conversion

Open a supported MP4 or audio file and export its soundtrack as MP3 or WAV. Codec support depends on your browser.

AI stem separation

The included offline engine estimates vocals, drums, bass, guitar, piano and other instruments. Website separation is not connected yet. Import separated stems here to mix them.

Download the offline engine

Separation estimates can contain bleed. Drums remain grouped unless you supply a separate kick stem. Automatic breath reduction never erases a detected region; word timing protects nearby words. Review before removing any breath completely. Without word timing, connected words may share one fade.

Protect words is always on. Automatic breath edits only reduce volume by up to 6 dB. Supplied word boundaries are protected with a 50 ms margin. Fades only touch quiet samples near segment boundaries. Full breath removal requires listening review in the offline engine.

Joyelle · iPhone Mixing & Mastering Engine

Keep the groove centered and make space around it. Joyelle shapes music for iPhone playback. Enable this profile for gentle mix-bus shaping, controlled width and 24-bit / 48 kHz WAV export. Compare with your original before release.

With separate stems, kick, bass, grouped drums and the lead vocal stay centered in this profile. A full stereo mix retains its existing instrument placement. Backing vocal layers remain spread. Instrument pan automation starts off; enable it for selective slow movement. Gentle 1.5:1 bus compression and attenuation-only peak protection preserve headroom. No loudness normalization or true-peak certification is claimed.

Frequency, panning & playback guide

Audio processing can shape the audible range (roughly 20 Hz–20 kHz). Phone speakers cannot reproduce deep bass like full-range speakers; avoid boosting sub-bass to compensate.
Vocal and instrument high-pass settings depend on the source. Vocals commonly start at 80–120 Hz; keep kick and bass fundamentals. Cut troublesome boxiness before adding brightness. The controls here shape the whole mix gently.
Pan from full left through center to full right. Keep lead vocals, kick and bass centered; place backing vocals, guitar, keys and percussion around them. Use modest movement and check mono.
Headphones reveal left/right placement. Check the final export on actual iPhone speakers at moderate volume, then headphones and a full-range system. A mono check reveals cancellation but does not simulate an iPhone speaker.
48 kHz / 24-bit is a practical production format. Higher sample rates do not create stronger bass, brighter vocals or wider stereo. Apple Music supports up to 24-bit/192 kHz with appropriate hardware; above 48 kHz requires an external DAC. Bluetooth from iPhone does not provide Apple Music lossless.
Spatial audio requires a compatible app, content and playback path. This studio exports conventional stereo; stereo widening is not Dolby Atmos or head-tracked Spatial Audio.

Apple: lossless playback requirements

Add your stems to begin. Choose Full mix / stereo master for an existing song, or assign instrument roles to separate stems.

Review before releasing. Automatic edits are estimates. Compare against your original vocal, especially around soft words and consonants. Keep your original files. Your files stay on this device; this studio does not publish your song.
