Signal Desk Pro is a professional audio player for iOS. Process, analyze, and export your mixes anywhere.
Your mix on every speaker. Before it's too late. Toggle any console mode to hear exactly how your mix will sound in the real world. Tap once to engage. Tap again to instantly A/B against your unprocessed source.
Professional metering. No studio required. A swipeable suite of meters gives you the visual analysis tools of a professional studio. In your pocket. From analog VU needles to EBU R128 loudness to a real-time stereo vectorscope — and Projector, a Milkdrop-class visualizer driven by your own track.
Connect Dropbox and Signal Desk Pro creates a single folder for you. Drop tracks in and they sync automatically, with new files, updated versions, and deletions detected on their own. Subfolders work too, and an image dropped into a folder becomes the cover art for the tracks inside it. Every sync opens a review screen grouped by folder, so you choose what lands in your library — anything you skip is offered again next time. Google Drive and local files import through a picker.
Activate any console mode and tap the share icon to render a full-quality processed version of your track, with your settings baked in. Export as WAV, AIFF, or AAC and send it anywhere via AirDrop, Dropbox, or Messages.
Device simulations, phase tools, stereo width control, and more. Everything you need to hear your mix the way your audience will.
