MYRIAD supports any sampling rate and channel count, is extremely metadata savvy, and supports Dropbox, Soundcloud, and FTP file transfers out of the box. 

If you deal with audio files on the Mac in any capacity, MYRIAD 4 will make your day. And if you deal with large numbers of files, it is – quite simply – an absolute must-have.

Analysis & Metadata

MYRIAD 4 lets you see and organize your audio by its properties...both in terms of audio measurement statistics as well as metadata. Sort and filter your assets by audio features including but nowhere near limited to program loudness, pitch, sample rate, DC offset or BPM, and read & write metadata properties from categories like Broadcast WAVE, Radio Traffic, or SoundCloud.


Actions & Workflows

MYRIAD 4 comes with a huge selection of Actions for processing your files, ranging from simple file conversions to time stretching and sending files via FTP. In the Workflow window, you assemble these into Workflows. You can, of course, save presets for your Actions and Workflows for maximum efficiency..
