15.64 RF64 files
RF64 is an audio file format. You have an option (set in Options > Audio File editing
preferences > Files tab) to support the RF64 file format. If this is activated, the standard
Wave file format switches automatically to the RF64 file format as soon as the file size ex-
ceeds 2GB, without any performance loss or interruption. This is especially useful when
recording very long sessions as there is no need to worry about file size limit (apart from disk
space availability).
An RF64 file uses the ".wav" extension but it can only be opened with an application that
supports the RF64 standard.

15.65 RMS
RMS (Root Mean Square) can be used as a measurement of intensity of sound (or AC
voltage, etc.) over a period of time. The RMS measurement calculates a practical average
value of all the points on a waveform as a single number over a variable period that could be
1 ms, 20 ms, or 1 hour.
RMS is often a good basis for determining an "equal level" when equalizing Clip volumes,
producing more natural results than using Peak levels, since RMS offers a more realistic
measure of the perceived "loudness" of a sound.

15.66 Sample rate
The Sample Rate, or sampling frequency, is the number of samples per second used to
store a sound. High sample rates are better able to approximate the original continuous
waveform, but require more storage space.

15.67 SMPTE timecode
The Society of Motion Picture and Television Engineers devised a code to synchro-
nize time between devices, the SMPTE time code. The time code is composed of
hours:minutes:seconds:frames.
Frames are fractions of a second based on the frame rate (which can take the values 24, 25,
29.97 and 30 frames per second).
