From first take to final master.
Record multitrack sessions, arrange waveform clips and takes, mix with effects, buses and automation, master with a full A/B preview, build AI-assisted instrumental ideas and stems, then turn the finished song into visualizers, lyric videos, music-video montages and social promos — all in your browser. Project audio and source media stay on your device by default.
Load your mix
Choose your character
Optional. Load a WAV or MP3 reference. Jam45 analyzes it locally, then maps tonal balance, loudness, dynamics and stereo character into your mastering controls.

PRO MASTERING CONTROLSOpen the full mastering chain
These controls feed the rendered mastering engine. The live sound check previews the main EQ, compression, width, saturation and limiter choices; the final render adds adaptive Dynamic EQ, precision multiband, de-essing and full quality control.
Professional Analyzer
Live Sound Check
Play your mix and adjust the mastering controls above. Changes are heard instantly.
Switch to Live settings to audition the selected profile and slider changes in real time. The rendered master performs the final precision loudness and limiter pass.
Mastering is performed on this device. Keep this tab open while Jam45 Studio works.

Record & Mix
Record and mix from one console: assign an input on the track, watch the live level, arm it, record, review, save, lock, then move to the next track. Finished mixes can go straight into Jam45 Mastering.
Built in: waveform arrangement, punch recording, loop-recorded take lanes and comping, detailed automation, buses, channel effects, vocal de-essing and pitch correction, freeze, stem export, reference A/B, tuner, automatic latency tools, autosave/recovery and local project storage.
Waveform Tracks & Editing
Record & Mix Console
Simple path: create a track → assign its input → watch the live meter → arm REC → Start Recording → Stop → review → Save Track → Lock Track → move to the next track.
Channel effects
Track
The advanced gate and vocal de-esser run locally in the browser. Keep live tracking effects light on slower computers; use the post-recording pitch-correction tool below for gentle vocal/lead tuning.
Local projects
Important: local projects can be lost if browser/site data is cleared. Export important recordings and mixes as backups. Avoid private/incognito mode for projects you need to keep.
Finish Your Mix
Leave headroom for mastering. -6 dB is a safe starting point.
Mix Down to 24-bit WAV creates one finished stereo WAV using the audible tracks and your fader, pan, EQ, effects, buses and automation settings. Muted tracks are left out. Use Send Mix to Jam45 Mastering when you want that stereo mix loaded directly into Master.
Jam45 Music Video Maker
Create visualizers, lyric videos, montage-style music videos and vertical promo clips locally in your browser.
Turn a finished song into a video
Load a song, add cover art or your own photos/video clips, choose a style, preview it, and export a finished social or YouTube-ready video. Your source media stays on this computer by default.
Build the whole music video on a real timeline
Multi-layer editing, keyframes, transitions, effects, speed curves, animated text, beat tools and local automatic lyric captions — without making the quick Video Maker harder to use.
Full Video Editor
New local project • not savedDrag either edge of the highlighted waveform selection, or drag the selected area itself to move the whole clip. The selected range is used by Preview and Export in every Video mode.
No montage media added yet.
MP4 export is used when the browser exposes a compatible MP4 MediaRecorder. If not, Jam45 automatically falls back to high-quality WebM instead of failing the render.
Build the song. Keep control of every track.
Generate an instrumental idea locally, split it into stems, then send those stems into Record / Mix for Jam45 EQ, effects, buses, automation and mastering.
Jam45 AI Engine
Install once and Jam45 handles the rest. The AI Engine runs quietly on this computer, starts with Windows, reconnects automatically, and keeps generation local.
Troubleshooting / Advanced
Describe the song
Hum it. Jam45 builds around it.
Optional: hum, whistle, or play a melody for up to 30 seconds. Jam45 uses it as the musical seed, then builds the arrangement you describe.
Advanced generation settings
Generated tracks
After handoff, generated stems are ordinary Jam45 mixer tracks. Use the same faders, pan, EQ, channel effects, buses, automation, arrangement and export tools as recorded audio.
Musician Tools
Everything below works locally on your device. Pick what you are working on instead of scrolling through one giant page.
Vocal Isolator / Remover
Separate a finished song into vocals and instrument tracks on your own computer, then download the isolated vocal, a vocals-removed instrumental, or the individual stems.
Choose a song to begin.
Separation uses Demucs in the private Jam45 AI Engine. Results vary with the mix: doubled vocals, heavy reverb and instruments sharing the vocal frequency range can leave artifacts.
Cut / Join / Trim Audio
Load one file to cut or trim it, or load several files to reorder and join them. Everything is processed locally in the browser.
Add one or more songs or clips.
Beat Maker
Build a full groove with produced drums plus a large library of genuine recorded acoustic drums and percussion, per-lane effects, and a tunable deep bass instrument — then export exactly what you hear.
Click steps to build your pattern. Each lane has Volume, Pan, Mute and Solo. 100% preserves the original level; Pan runs L100–Center–R100. Use ▶ beside a drum lane to audition it with the current lane mix settings.
Sound Profiles remember your drum/percussion choices, Volume, Pan, Mute/Solo, lane FX and Deep Bass tone settings without overwriting the programmed beat. Lane FX now open directly beneath the instrument you are editing.
Audio Converter
Open audio your browser can decode and create a fresh 24-bit WAV or 320 kbps MP3 without uploading it.

Audio Repair
Clean common recording problems with conservative local processing: DC offset, isolated clicks, electrical hum, background-noise gating and safe peak normalization.
Choose an audio file.
Repair is intentionally conservative. Severe clipping, room echo and complex broadband noise may require a dedicated restoration editor.
Pitch Shifter
Transpose a song or practice track up or down while keeping approximately the same tempo and length.

Tempo Changer
Slow down a difficult passage or speed up a track while preserving its musical pitch.

Analyze before you release
Technical second opinions without uploading your songs.
Audio Lab
One upload gives you mix/loudness analysis, BPM, estimated key, stereo health and a release-readiness report. Your audio never leaves this device.
Technical report
Use this as a technical second opinion, not as a replacement for listening.
Audio file diagnostics
Cover Art Checker
Check your artwork master before you build the release. Jam45 Studio looks at format, dimensions, shape and file size without uploading the image.
Make a release-ready square copy
Jam45 Studio uses high-quality browser resizing. Enlarging a small image can meet pixel dimensions, but it cannot recreate detail that was not present in the original.
Promo Artwork Generator
Turn a cover into square posts, stories and video thumbnails with release-ready announcement text.
Metadata & Tag Checker
Inspect common MP3 ID3 tags and WAV technical headers before delivery. Nothing is uploaded.

This tool organizes collaborator information; it does not provide legal advice or register the work with a PRO, publisher, distributor or copyright office.
