Enumeration Type Documentation

◆ LengthOfOneBeat

enum class tracktion::core::tempo::LengthOfOneBeat

strong

Used to determine the length of a beat in beat <-> time conversions.

Enumerator

dependsOnTimeSignature

Signifies that the length (in seconds) of one "beat" at any point in an edit is considered to be the length of one division in the current bar's time signature.

So for example at 120BPM, in a bar of 4/4, one beat would be the length of a quarter-note (0.5s), but in a bar of 4/8, one beat would be the length of an eighth-note (0.25s)

isAlwaysACrotchet

Signifies the length of one beat always depends only the current BPM at that point in the edit, so where the BPM = 120, one beat is always 0.5s, regardless of the time-sig.

E.g. 7/4 is treated the same as 7/8/
