Logic Pro 7.1 – Apple Loops (2005-0905) 21 of 23

Indexing non Apple Loops

Importing standard audio files (aiff, wav)

Regular audio files (aiff, wav) with no Apple Loop tags can also be indexed with the Loop Browser. This provides you with a search engine for regular

audio files. You can use the following search fields:

• Name: OF course you can search for the name of the indexed audio files

• Folder: When you drag a whole with audio files onto the Loop Browser for indexing, then the name of the folder will be part of the “Jam Pack

Management” popup menu. This enables you can restrict your search i.e. to a specific FX Library folder.

• Keyword Tags: This is one of the undocumented features of the Loop Browser: The audio files of course have no keyword tags, which can be

indexed. The Loop Browser however uses some intelligent algorithm to create some Keyword tags on fly, automatically when you index the

audio files. The Loop Browser analyses each audio file an looks if any word in the file name or its folder name (and subfolder) matches any

phrase of the “Genre”, “Instrument” or “Mood Descriptor” tag available for Apple Loops. All the matching keywords will be attached as tags to

the indexed audio file. The tags are stored in the index file not the actual audio file. The audio file stays untouched.

The “matching algorithm” goes even one step further: It has some intelligence build in which can interpolate keywords from similar words or

phrases:

o The file name “If you are happy” or “We wish you a merry Christmas” will be interpreted with the tag “cheerful”

o The file name “Angry River” will be interpreted with the tag “Intense”

Importing Acid Loops

Acid Loops only include transition markers for tempo matching but no other metatags

Acid Loops to Loop Browser

• You can drag an Acid file (acidized wav file) direct onto Logic’s "Loop Browser”. This has much more advantages than the AUL

procedure:

• Logic uses the tempo matching info of the Acid file to create the transient marker

• The key tag and the Signature tag will also be detected

• The great feature is the automatic Keyword Tags creation. If the file name or the folder name (if you drag a folder) contains any of the

keywords of the “Genre” “Instrument” or “Mood Descriptor” then it will index those tags on the fly. You can manipulate the tag

creation before dragging them to the Loop Bowser by putting all the acid files in a folder naming it with all the keywords you want

them to have and drag it over the Loop Browser

• The original wav file stays untouched

• All the added tags are stored in the index file not in the audio file!

Acid Loops to Apple Loops Utility (ALU)

ALU treats an Acidized wav file like a regular wave file when you open it: it detects the transition marker and key but no tags are set. You have

to set them manually. When you enter a whole Acid Library then you can use the Batch function in ALU. After ‘tagging” the files, you save them

as new “genuine” Apple Loops.

What audio file format can the Loop Browser index and what metatags will be indexed
