Create segments of spoken recordings
You can use Remove Silence to divide long spoken passages into several convenient
segments, like sentences, words, or syllables. For film synchronization or jingles, you can
move or reposition the speech segments by simply dragging them around in the Tracks
area.
Tempo changes allow you to simulate a time compression or expansion effect, as the
syllables automatically move closer together, or farther apart.
Create segments for drum loops
Dividing drum loops into small segments is a good way to perfectly synchronize them. For
example, in audio passages where the bass drum and snare are completely separate, you
can often use Remove Silence to isolate each individual beat.
Optimize synchronization
Different computers, different synchronization sources (internal or SMPTE code), different
tape machines, and—in theory—different samplers or hard disk recording systems will
exhibit slight variations in clock speed. Changing just one component can lead to a loss of
synchronization between recorded audio material and MIDI. This is particularly applicable
to long audio regions.
This is another situation where the Remove Silence function can help, by creating several
shorter audio regions, with more trigger points between the audio and MIDI events.
For example, you can use this method to roughly split up a whole audio file, and then divide
the new regions, using different parameters. The new regions can then be processed again
with the Remove Silence function.
Optimize files and regions
You can use Remove Silence to automatically create regions from an audio file that
contains silent passages, such as a single vocal take that runs the length of a project. The
unused regions or portions of the audio file can be deleted, saving hard disk space, and
simplifying (file and) region management.
Use Remove Silence to extract audio files
Many sample library discs (CD or DVD) contain thousands of audio recordings stored as
AIFF or WAV files. You can use Remove Silence to split these into individual regions, which
can be used directly in the Tracks area. In addition, you can convert regions into individual
audio files (samples), which can be used in the Sampler.
