Re: How to get Extended File Info

No, I’ve used it with MP3 and AAC and AIFF; I’m pretty sure it supports every format there’s a system codec for (i.e. most audio formats except Ogg and FLAC, but you can get 3rd party components to do those.)

Rumor (i.e. Stack Overflow) has it that AVFoundation will only work with AAC, but I have not confirmed that myself.

AVFoundation has a higher-level OOP API for this. Look for methods for accessing metadata, and constants defining the various metadata types like Title, Artist, etc.

AudioToolbox, especially Audio File Services (don’t have links but should be able to search docs easily), appear to have this capability.

Hi,

Looking at the Finder “Get Info” window, for instance for an mp3 file, it displays under the “More Info” tab, the Title, Authors, etc.

How can I get this information programatically?

Thanks a lot
All the Best
Dave
