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.
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 gate uses AudioWorklet when available. Keep tracking effects light on slower computers and do detailed processing while mixing.
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.
Mixdown & Mastering handoff
Leave headroom for mastering. -6 dB is a safe starting point.
Musician Tools
Everything below runs in your browser. Pick what you are working on instead of scrolling through one giant page.
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.

Song Split Sheet Builder
Document collaborators while everyone still remembers the agreement. Drafts stay in this browser; Jam45 does not receive the split-sheet data.
This tool organizes collaborator information; it does not provide legal advice or register the work with a PRO, publisher, distributor or copyright office.
