audio-contextcljs
An atomic reference to a global audio context that gets created the first
time you call clock and is reused for any subsequent clocks.
An atomic reference to a global audio context that gets created the first time you call `clock` and is reused for any subsequent clocks.
callback-at-time!cljs
(callback-at-time! clock-atom f deadline & {:as opts})Schedules f to run before deadline. Returns the event.
opts may contain :tolerance-early and :tolerance-late for optionally
overriding the clock's timing window for events.
Schedules `f` to run before `deadline`. Returns the event. `opts` may contain :tolerance-early and :tolerance-late for optionally overriding the clock's timing window for events.
clear!cljs
(clear! {:keys [clock-id] :as event})Unschedules an event by removing it from its clock's event queue.
Unschedules an event by removing it from its clock's event queue.
current-timecljs
(current-time {:keys [context]})Returns the current time of a clock's audio context, in milliseconds.
Returns the current time of a clock's audio context, in milliseconds.
repeat!cljs
(repeat! {:keys [deadline] :as event} time)Sets the event to repeat every time milliseconds
Sets the event to repeat every `time` milliseconds
set-timeout!cljs
(set-timeout! clock-atom f delay-ms & {:as opts})Schedules f after delay-ms milliseconds. Returns the event.
opts may contain :tolerance-early and :tolerance-late for optionally
overriding the clock's timing window for events.
Schedules `f` after `delay-ms` milliseconds. Returns the event. `opts` may contain :tolerance-early and :tolerance-late for optionally overriding the clock's timing window for events.
start!cljs
(start! clock-atom)Remove all scheduled events and start the clock.
Remove all scheduled events and start the clock.
time-stretch!cljs
(time-stretch! e ratio)(time-stretch! e time-reference ratio)Reschedules events according to a time-reference and a ratio.
If the event is a repeating event, adjusts its repeat-time accordingly.
The first argument can be either a single event or a list of events. Returns the rescheduled event, or a list of rescheduled events, depending on the input type.
e.g.
(time-stretch! e (current-time clock) 0.5)
^-- makes an event e occur twice as soon as it would otherwise
If time-reference is omitted, the default value is the current time of the
event's clock.
