5.2 Sample Files

A sample is a ﬁle that contains audio data. Live can play both uncompressed ﬁle formats (WAV,

AIF and Sound Designer II for Mac) and compressed ﬁle formats (MP3, AAC, Ogg Vorbis, Ogg

FLAC and FLAC). (Please note that not all of these ﬁle formats can be played in the Lite Edition.)

A note on using Variable Bit Rate (VBR) ﬁles: Please install QuickTime for decoding purposes if

you do not already have it on your system. It can be downloaded from the Apple website

As Live plays the samples directly from disk, you can work with a large number of (large)

samples without running into RAM memory limitations. Please note, however, that you may run

into disk throughput problems if your disk is nearly full, and/or (on Windows systems) highly

fragmented. Hard drive rotation speed can also affect disk performance. Refer to the section on

managing the disk load (page 571) for more information.

Live can combine uncompressed mono or stereo samples of any length, sample rate or bit depth

without prior conversion. To play a compressed sample, Live decodes the sample and writes the

result to a temporary, uncompressed sample ﬁle. This usually happens quickly enough that you

will be able to play the sample right away, without waiting for the decoding process to ﬁnish.

Note: When adding a long sample to a project, Live might tell you that it cannot play the sample

before it has been analyzed. Please see the section on analysis (page 42) for an explana-

tion.

5.2.1 The Decoding Cache

To save computational resources, Live keeps the decoded sample ﬁles of compressed samples

in the cache. Maintenance of the cache is normally not required, as Live automatically deletes

older ﬁles to make room for those that are new. You can, however, impose limits on the cache

size using the File/Folder Preferences’ Decoding Cache section. The cache will not grow larger
