Use the sfrecord~ object to record and save MSP output as an audio file.
Sets the number of input channels, which determines the number of inlets that the sfrecord~ object will have. The maximum number of channels is 64, and the default is 1. The audio file created will have the same number of channels as this argument. Whether you can actually record the maximum number of channels is dependent on the speed of your processor and hard disk.
An optional second argument sets the buffer size. The defult value is 20160.
Bits Per Sample
dither [int] (default: 0)
Enable triangular dithering when writing PCM (integer) files.
0 = 'Off' ( Apply no dithering when writing PCM files )
1 = 'Dither' ( Apply triangular dither (TPDF) when writing PCM files )
2 = 'Dither + Noise Shaping' ( Apply triangular dither (TPDF) with noise shaping when writing PCM files )
Sets the number of channels for the audio file to be recorded (1-64). The default is 1.
quantization [int] (default: 0)
Select the quantization rule when writing PCM (integer) files.
0 = 'Round' ( Round when quantizing to integer values. )
1 = 'Floor' ( Floor when quantizing to integer values. )
Upsamples or downsamples the file. Sample rates are expressed as floating-point values - 1.0 is the current sampling rate, 0.5 is half the current, 2.0 is twice the current sample rate, etc.
sortloop [int] (default: 0)
When the sortloop attribute is on, a recording made with the message will be re-ordered so that the beginning of the file is the beginning of the most recent recording. If sortloop is off (default), the beginning of the recording will likely be somewhere in the middle of the resulting audio file.
Common Box Attributes
Recording may also stop spontaneously if there is an error, such as running out of space on your hard disk.
: 8-bit integer
: 16-bit integer
: 24-bit integer
: 32-bit integer
: 32-bit floating-point
: 64-bit floating-point
: 8-bit "mu"-law encoding
: 8-bit a-law encoding
The optional second argument, a 0 or 1, specifies whether or not byte-swapping should be used, which is only useful when writing a 'raw' audio file.
The time, in milliseconds, since recording of the file began. If recording has stopped, the signal value will remain at the length of the last recording until a new recording is started.
