SWAP PAL: Multichannel Swapper

Take control of multichannel audio directly from your iPhone or iPad. SWAP PAL makes it easy to import, inspect, monitor, reorder, and export audio channels without returning to a desktop workstation. IMPORT AND INSPECT Import WAV and AIFF audio from the Files app, iCloud Drive, Dropbox, OneDrive, Box, and other installed file providers. Work with a single interleaved audio file or select 1, 2, 6, or 8 mono files for interleaving. VIEW YOUR AUDIO See every channel as an individual waveform with channel labels, timecode, transport controls, and output meters. Move through the audio, monitor playback, and use mute, solo, or Multi Solo to inspect individual channels. CHOOSE THE CORRECT CHANNEL ORDER Quickly switch between SMPTE and Film channel layouts, or use Manual mode to create a custom channel order. SWAP PAL clearly identifies each channel so you can confirm the arrangement before exporting. EXPORT AND SHARE Create a new reordered audio file while preserving the original. Save the result to Files or send it directly to another compatible app using the iOS Share menu. The exported file is automatically loaded back into SWAP PAL for immediate verification.
