mc.record~ Reference

Record sound into a buffer

mc.record~

Description

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

Arguments

buffer-name [symbol]

Obligatory. Names the buffer~ where record~ will write the recorded samples.

input-channels [int]

Optional

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.

Attributes

append [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.

loop [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.

loopend [10 atoms]

Sets the loop end point for the object. The sampling interval can be specified in any of the time formats used in Max.

loopstart [10 atoms]

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.

Common Box Attributes

Messages

int

Arguments

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

Arguments

recording-flag (0 or nonzero) [float]
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.

list

Arguments

loop-start/loop-end/timing-parameters [list]
list can be used to specify loop-start and loop-end points or timing/synchronization settings for transport.

anything

Arguments

loop-start/loop-end/timing-parameters [list]
list can be used to specify loop-start and loop-end points or timing/synchronization settings for transport.

(mouse)

Double-clicking on record~ opens an editing window where you can view the contents of its associated buffer~ object.

reset

The word reset resets the record-loop points to the default values (which record through the whole duration of the assigned buffer~).

set

Arguments

buffer-name [symbol]
The word set, followed by the name of a buffer~, changes the buffer~ where record~ will write the recorded samples.

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~.

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.
