APM Sweep is the successor of the well known APM Tool: it let you quickly measure the acoustical performance of a room (reverberation time, clarity, etc. in octave and third octave bands), check if that room is well suited for its purpose and, if not, choose which materials can improve the acoustical quality. Everything still there but with an exciting improvement: now you can use all the power of the Exponential Sine Sweep technique for the measurement process, so your results can be extremely precise and accurate. You can also, save, load and export results in common spreadsheet format. The app can also generate pdf reports with photos. A tutorial slideshow explains the app use. Required at least iOS 11.0

( THIS IS AN AUDIOUNIT. AudioUnits are app extensions, requiring any audio host application to perform. ) Use the same AudioUnits across all modern Apple devices, including the iPhone and the Mac (Apple Silicon). Native MacOS apps like GarageBand, MainStage 3 and Logic Pro X are fully supported. Any 3rd-party AUv3 supporting host should be able to host the plugin too. The JAX ESSENTIAL SERIES Phaser is a multi stage phaser modulation effect that uses multiple allpass filters, to produce all kinds of the famous phaser effect. A low frequency oscillator modulates depth and speed of the filter modulation on both stereo channels for various living and moving sound nuances. Make static sounding voices more interesting or create sweaping special effects. You may share the presets for this effect across all your supported devices. Around 200 factory presets are included, you can make and export/import your own. The complete manual is included and can be previewed on our support website: https://audio.digitster.com For advanced usage (i.e. mastering and exciting), we recommend to select the phaser from our SELECTIVE RANGE SERIES, which allows to limit the frequency range for processing. This build is truly 'universal', meaning, the audio unit is available for: - iOS (all actual iPhones) - iPadOS (all actual iPads) - macOS (Apple Silicon) - visionOS (Apple Vision Pro) Requirements: MacOS 11.0++ iOS 14.0++ Behaviour on all devices is identical. The parametric interface is resizeble and adopts to any screen size and orientation. This especially applies to Logic Pro X and all hosts with adjustable window sizes on all platforms. Display contrast can be adjusted freely and is now saved with each preset.
