Song structure and size

Song structure

The following diagram shows the structure of songs saved on the hard disk.

As you can see from the diagram, each song consists of the following two areas.

	■ System area
■ Song	Various settings
	Song name
(maximum 6.4 GB per song)
	Libraries
	Scenes
	Automix data

■ Data area 16 tracks × 8 Stereo track Samples Undo data

Hard disk

(maximum 64 GB/ ■ CD production work area

30,000 songs) Required when producing an audio CD

(not allocated beforehand)

❍System area

This area contains data for various settings, the song name, libraries, scenes, and automix data. The size of the system area is fixed at approxi- mately 2 MB.

❍Audio area

This area contains audio data for the audio tracks and stereo track, sample data, and undo data. The size of the audio area will depend on the size of the recorded tracks and virtual tracks. You can increase the available free area by deleting the audio data of unneeded tracks and then executing the Song Optimize operation.

Usable hard disks/song capacity

The AW4416 can use a hard disk of up to 64 GB, and allows you to create a max- imum of 30,000 songs. However, the size of each song (system area + data area) is limited to a maximum of 6.4 GB.

•If you have used up the available space of a song or of the hard disk, you can delete the audio data of unwanted tracks or virtual tracks (→ P.156), and exe- cute the Song Optimize operation (→ P.182) to create more free space. (It is not possible to increase the free space by performing other operations.)

•The song size (SIZE) displayed in the song list shows only the size of the data area. Be aware that in actuality, each song also uses a system area of approxi- mately 2 MB. On the AW4416, data sizes are displayed as 1 KB= 1,024 bytes.

Work area for audio CD production

When using an internal/external CD-R/RW drive to create an audio CD, you will need at least as much work area on the hard disk as occupied by the audio data being written to the CD. For example in order to create a 74 minute audio CD, the internal hard disk must have sufficient free area to record a 74 minute or longer 16 bit/44.1 kHz stereo track (approximately 650 MB).

To check the amount of free area on the internal hard disk, select a 16 bit/

44.1 kHz song, and press the REC TRACK SELECT [ST] key to put the stereo track
