record~

Record sound into a buffer

Description

record~ records a signal into a buffer~ object. You can record up to 4 channels by specifying the optional argument. Recording stops when it has filled up the buffer~.

Arguments

Name Type Opt Description
buffer-object-name symbol Obligatory. Names the buffer~ where record~ will write the recorded samples.
number-of-input-channels int opt Specifies the number of input channels (1, 2, or 4). This determines the number of inlets record~ has. The two rightmost inlets always set the record start and end points.

Messages

int recording-flag (0 or nonzero) [int]
In left inlet: Any non-zero number starts recording; 0 stops recording. Recording starts at the start point unless append mode is on.

In the inlet to the left of the right inlet: Set the start point within the buffer~ (in milliseconds) for the recording. By default, the start point is 0 (the beginning of the buffer~).

In right inlet: Sets the end point of the recording. By default, the end point is the end of the buffer~ object's allocated memory.
float recording-flag (0 or nonzero) [float]
Converted to int.
list loop-start/loop-end/timing-parameters [list]
A list which can specify loop-start and loop-end points or timing/synchronization settings for transport.
anything loop-start/loop-end/timing-parameters [list]
Performs the same function as list.
append append-recording-flag (0 or nonzero) [int]
The word append, followed by a non-zero number, enables append mode. In this mode, when recording is turned on, it continues from where it was last stopped. append 0 disables append mode. In this case, recording always starts at the start point when it is turned on. Append mode is off initially by default.
(mouse) Double-clicking on record~ opens an editing window where you can view the contents of its associated buffer~ object.
loop loop-recording-flag (0 or nonzero) [int]
The word loop, followed by a non-zero number, enables loop recording mode. In loop mode, when recording reaches the end point of the recording (see above) it continues at the start point. loop 0 disables loop recording mode. In this case, recording stops when it reaches the end point. Loop mode is off initially by default. The record~ object also takes into account any changes in the buffer~ object's sampling rate if the buffer~ object's length is modified for the purpose of establishing loop points.
set buffer-object-name [symbol]
The word set, followed by the name of a buffer~, changes the buffer~ where record~ will write the recorded samples.
reset The word reset resets the record-loop points to the default values (which record through the whole duration of the assigned buffer~).
signal In left inlet: When recording is turned on, the signal is recorded into the sample memory of a buffer~ at the current sampling rate.

In middle inlets: If record~ has more than one input channel, these inlets record the additional channels into the buffer~.

Attributes

Name Type g/s Description
loopend atom Sets the loop end point for the object. The sampling interval can be specified in any of the time formats used in Max.
loopstart atom Sets the loop start point for the object. The sampling interval can be specified in any of the time formats used in Max.
transport symbol The name of a transport object with which to associate. By default the global transport is used.

Output

signal: Sync output. During recording, this outlet outputs a signal that goes from 0 when recording at the start point to 1 when recording reaches the end point. When not recording, a zero signal is output.
