GET READY
Headphones on. Your next layer awaits.
Record. Bounce. Create. A few practical answers to keep you moving.
Press PLAY. Check device media volume, MASTER LEVEL, track LEVEL, Mute and Solo. Make sure the playhead is inside a selected audio range. Check connected headphones and Bluetooth devices. In Audio Diagnostics, PLAY TEST TONE checks the playback path only. Safari/iOS controls the output device; the Studio cannot force the iPhone speaker.
Use HTTPS or localhost. Press RECORD and allow microphone access in your browser settings. Close other apps using the microphone. Use headphones and keep this page in the foreground. Audio Diagnostics offers a separate two-second microphone capture test that does not change your tracks. A playback test tone does not prove that your microphone works.
Choose IMPORT AUDIO, then select a local WAV or MP3 file. No microphone permission or previous recording is needed. If the file is only in iCloud or another file provider, download it to the device first. Wait for decoding; a large file needs time and memory. Read any error in the status line. A failed import keeps the current tracks.
Press CLEAR TAKE on TRACK 02. This clears only that track; your base on TRACK 01 stays unchanged. UNDO can restore the take while it remains in the six-step history.
Download PROJECT BACKUP if you want to keep this project, then press NEW PROJECT and confirm. Both tracks are cleared. The previous state remains temporarily available through UNDO, so its audio may still occupy local storage.
SAVE LOCAL writes the project into this browser on this device. Changes are also saved automatically when possible. Check the save message below the project buttons. PROJECT BACKUP downloads a separate .mullivox file that you can keep outside the browser. Local browser storage can be cleared; keep backups of important work.
The last successful local save is restored automatically on the same browser and website address. To open a downloaded backup, choose OPEN PROJECT and select its .mullivox file. WAV/MP3 files are imported with IMPORT AUDIO instead.
Listen to your new take with PLAY first. BOUNCE mixes the audible selected ranges with their levels, pan and effects into a new TRACK 01, then clears TRACK 02 for another recording. Audio outside the trim markers is not included in the new mix. UNDO restores the previous sources; a project backup keeps them beyond the temporary history. RESET TRIM selects the full original source before bouncing.
Browsers limit storage. Low disk space, private browsing, disabled storage, another open Studio tab or an operating-system interruption can prevent a save. Large audio is stored in small blocks, but total storage and memory limits still apply. A failed save shows a warning and keeps the last successful local save. Download PROJECT BACKUP. Removing a take or starting a new project keeps Undo audio until it leaves the history.
Playback only. Does not request or test the microphone.
Requests microphone access for a short local capture. The test is discarded; your project is unchanged.
iPhone output routing is controlled by Safari and iOS. Check media volume and connected headphones.
