MediaZip vs Spatial Audio Preview

A video too large to send? Photos taking up space? MediaZip helps you get videos, images and PDFs ready for sharing, right on your iPhone or iPad. MAKE FILES EASIER TO SHARE • Compress videos and adjust quality or resolution for messaging, email and uploads. • Convert videos to MP4 or MOV, or extract their audio as MP3 or M4A. • Compress photos, resize images and convert between supported image formats. • Reduce PDF size, turn images into PDFs and export PDF pages as JPG or PNG. CHOOSE, PROCESS, SHARE Import from Photos, Files or another app. Pick the operation you need, compare the original and output sizes, then save or share the result. Reopen an item in History when you want to process it again. File processing takes place on your device, without uploading your media to a conversion server. Handy for sending family videos, preparing class materials or managing everyday files.

Spatial Audio Preview is a focused tool for hearing exactly how Apple's spatial audio renderer handles your files. Load any audio or video file and switch between Apple's Music and Movie spatial rendering profiles in real time. Spatial Audio Preview reads your file's true format — sample rate, bit depth, channel count, and channel layout, including Dolby Atmos and multichannel surround layouts — and shows you exactly what's playing. The app also tells you whether your connected output (AirPods, Beats, or other accessories) actually supports spatial audio rendering, so you always know if what you're hearing is spatialized or just raw channels being played back. Features: • Switch between Music and Movie spatial rendering modes on the fly — the same modes used by Apple Music, Apple TV, and more. • View info on the current file, such as sample rate, bit depth, channels, and layout. • Play back audio in several channel layouts, including stereo, surround, and Dolby Atmos. • See if your device and headphones support spatial audio playback. • Background playback with lock screen and Control Center controls allow you to listen with the device locked or unlocked. • Spatial Audio Preview is built with accessibility in mind with a VoiceOver-first interface. Spatial Audio Preview doesn't collect, transmit, or store any of your data. Everything happens on your device. Supported file types: • WAV • AIFF • CAF • M4A • MP4 • MOV Supported channel layouts: • Mono • Stereo • Quadraphonic • 5.0 • 5.1 • 6.0 • 6.1 • 7.1 • 5.1.2 • 5.1.4 • 7.1.2 • 7.1.4 • 9.1.6 • Dolby Atmos (E-AC-3) • Dolby Digital (AC-3)
